Description

  The present invention relates to an electronic device, a gaming machine, and an electronic device authentication method that include a plurality of substrates and authenticate communication between these substrates.

  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 control command information 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, Patent Document 2 transmits control command information from the main control board to the sub control board, and further transmits a state monitoring command for monitoring the communication state of the control command information in a predetermined communication path. Describes a configuration for verifying the validity of control command information using a status monitoring command and stopping control of a control target when it is determined that there is an error.

  Further, as in Patent Document 2 described above, when a state monitoring command different from the control command information is transmitted from the main control board to the controlled board, the gaming machine may be cheated ("got" action). Since the state monitoring command is easily analyzed illegally 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 a machine. 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. There is also a problem peculiar to gaming machines that the processing load on the main control unit cannot be increased due to the authentication process.

Then, based on the individual identification value corresponding to the authentication history data that matches the peripheral history data among the extracted three or more types of authentication history data, the individual identification in the main control unit The storage order of values can be determined. Then, after the storage order of the individual identification values is determined, the peripheral unit identifies the storage order based on the command value of the control command information received from the main control unit, and matches the individual identification value corresponding to the storage order. The authentication history data is extracted by removing the expected value from the received authentication information by the additional method. Then, the peripheral unit can authenticate the main control unit based on the determination result of whether or not the extracted authentication history data and the peripheral history data match.

  According to the present invention described in claim 2, the main control board, for example, at the predetermined timing such as at the time of start-up, at the time of reset, etc., the leading individual identification value from among three or more types of individual identification values And the three or more types of individual identification values are stored in the individual identification value storage means in a predetermined order from the determined first individual identification value. When the main control board transmits control command information to the peripheral board according to the operation of the gaming machine, the main control board generates history data indicating the history by the history generation method. The main control board calculates the command value and random number value of the control command information by a predetermined calculation method, and from among the storage order of three or more types of individual identification values stored in the individual identification value storage means, One storage order corresponding to the calculation result is extracted. The main control board can generate the authentication information by adding the extracted individual identification value of the storage order to the history data by a predetermined addition method, and transmit the authentication information to the peripheral board. On the other hand, the expected value storage means of the peripheral board stores three or more types of expected values that match each of the three or more types of individual identification values of the main control board. And when the peripheral board receives the control command information from the main control board, the peripheral board performs predetermined processing corresponding to the control command information, and peripheral side history data indicating the history of the control command information received from the main control board, It is generated by the same history generation method as the main control board. Based on the command value of the control command information received from the main control board, the peripheral board specifies the storage order to be extracted by the main control board from the storage order of the three or more types of individual identification values. The peripheral board extracts three or more kinds of authentication history data by removing each of the three or more kinds of expected values stored in the expected value storage means from the received authentication information by the same additional method as the main control board. Then, based on the individual identification value corresponding to the authentication history data that matches the peripheral history data among the extracted three or more types of authentication history data, the individual identification on the main control board The storage order of values can be determined.

The authentication history data is extracted by removing the expected value from the received authentication information by the additional method. Then, the peripheral board can authenticate the main control board based on the determination result of whether or not the extracted authentication history data matches the peripheral history data.

  According to the present invention described in claim 4, for example, control command information is identified and disordered for each of a plurality of types of control command information in the electronic device during the design and manufacture of the electronic device. A command value for specifying one individual identification value can be set by calculation with a numerical value. Then, the main control unit determines a head individual identification value from among three or more types of individual identification values, for example, at a predetermined timing such as at the time of activation, at the time of resetting, and the determined head individual identification Three or more types of individual identification values are stored in the individual identification value storage means according to a predetermined order from the value. When the main control unit transmits the control command information to the peripheral unit according to the operation of the electronic device, the main control unit generates history data indicating the history by the history generation method. The main control unit calculates the command value and random number value of the control command information by a predetermined calculation method, and from among the storage order of three or more types of individual identification values stored in the individual identification value storage means, One storage order corresponding to the calculation result is extracted. The main control unit can generate authentication information by adding the extracted individual identification value of the storage order to the history data by a predetermined addition method and transmit the authentication information to the peripheral unit. On the other hand, the expected value storage means in the peripheral portion stores three or more types of expected values that match each of the three or more types of individual identification values of the main control unit. Then, when the peripheral unit receives the control command information from the main control unit, the peripheral unit performs predetermined processing corresponding to the control command information, and peripheral side history data indicating the history of the control command information received from the main control unit, It is generated by the same history generation method as the main control unit. Based on the command value of the control command information received from the main control unit, the peripheral unit specifies the storage order to be extracted from the storage order of the three or more types of individual identification values. The peripheral unit extracts each of three or more types of expected values stored in the expected value storage unit from the received authentication information by the same additional method as the main control unit, and extracts three or more types of authentication history data. Then, based on the individual identification value corresponding to the authentication history data that matches the peripheral history data among the extracted three or more types of authentication history data, the individual identification in the main control unit The storage order of values can be determined. Then, after the storage order of the individual identification values is determined, the peripheral unit identifies the storage order based on the command value of the control command information received from the main control unit, and matches the individual identification value corresponding to the storage order. The authentication history data is extracted by removing the expected value from the received authentication information by the additional method. Then, the peripheral unit can authenticate the main control unit based on the determination result of whether or not the extracted authentication history data and the peripheral history data match.

  As described above, according to the present invention, the main control unit stores three or more types of individual identification values whose arrangement order is determined in a random rotation order, and stores existing control command information. By simply calculating a command value and a random value, one individual identification value is extracted from three or more types of individual identification values from the storage order corresponding to the calculation result, and the extracted individual identification value is used as history data. Since the added authentication information is generated and transmitted to the peripheral part, even if the peripheral part uses the authentication information history data for authentication of the main control part, the individual identification value added to the history data is a random value. Therefore, the regularity of the authentication information is lost, and it can be expected to prevent unauthorized analysis of the authentication information. In addition, since the storage order of the three or more types of individual identification values in the main control unit changes randomly, the individual identification values extracted based on the storage order change. It can be changed in a more complicated manner, and can contribute to prevention of unauthorized analysis of authentication information. In addition, the peripheral unit determines the storage order of three or more types of individual identification values in the main control unit from the storage order specified based on the control command information and the authentication history data extracted from the authentication information. If the peripheral part stores only the arrangement order of three or more types of individual identification values, the main control unit can detect and determine the storage order changed. Unauthorized analysis of authentication information can be made difficult. The peripheral unit extracts authentication history data from the authentication information using only the expected value corresponding to the command value of the control command information with respect to the three or more types of expected values. Since the main control unit is authenticated based on the determination result of whether or not the side history data match, the pattern to be extracted by the main control unit can be changed by different types of command values. The main control unit does not need to determine (recognize) the change, and the peripheral unit can bear the processing related to the authentication of the main control unit. Therefore, the pattern to be extracted is linked to a plurality of types of command values. It is possible to switch, and it is possible to make fraud analysis on authentication information even more difficult. Furthermore, since the main control unit can store three or more types of individual identification values in advance, it is not necessary to perform complicated calculations when generating authentication information, and an increase in processing load on the main control unit can be prevented. On the other hand, since the peripheral unit is configured to confirm and authenticate the communication continuity of the control command information based on the history data, it can detect unauthorized communication switching due to unauthorized control command information. It can contribute to prevention of communication switching. Moreover, since the peripheral part extracts the authentication history data from the authentication information using one or a plurality of expected values, the authentication history data and the peripheral side are added when the regular individual identification value is not added to the history data. Since the history data does not match, fraud can be reliably detected. In addition, for example, when an illegal board intervenes between the main control unit and the peripheral part, the processing load must be increased because the analysis load on the illegal board increases, so the cost and design difficulty are reduced. By increasing the number, it is possible to contribute to deterring production of illegal substrates. Therefore, it is possible to confirm the communication continuity of the control command information and to make it difficult to analyze the authentication information used for authentication by using an existing configuration and minimizing an increase in processing load on the main control unit.

  The prize ball control unit 203 performs control for paying out the number of prize balls at the time of winning a prize to the payout unit 291 connected via the I / F 284. The award ball control unit 203 detects an operation of launching a game ball with respect to the launch unit 292 and controls the launch of the game ball in the launch unit 292. The payout unit 291 includes a motor for paying out a predetermined number from the game ball storage unit. The winning ball control unit 203 controls the paying unit 291 to pay out the number of winning balls corresponding to the game balls won in each winning port (start winning port 105, normal winning port 107, large winning port 109). Do.

  The launcher 292 launches a game ball for a game, and includes a sensor that detects a game operation by the player, a solenoid that launches the game ball, and the like. When the prize ball control unit 203 detects a game operation by the sensor of the launch unit 292, the game ball 103 is intermittently fired by driving a solenoid or the like in response to the detected game operation, and the game area 103 of the game board 101 is played. A game ball is sent out.

  The main control unit 201, the effect control unit 202, and the prize ball control unit 203 configured as described above are provided on different printed circuit boards (main control board, effect board, and prize ball board). 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 control command information for operating the peripheral board 330, and includes a data storage unit 311, a determination unit 312, a history data generation unit 313, a calculation unit 314, an extraction unit 315, and authentication information. A generation unit 316 and a transmission unit 317 are included. The main control board 310 is formed of a board different from the peripheral board 330 and is electrically connected so that unidirectional communication with the peripheral board 330 is possible.

  The data storage unit 311 corresponds to the individual identification value storage means of the present invention, and includes control command information (control command), individual identification value, authentication information, history generation method data (history generation) transmitted to the peripheral part (peripheral board 330). System), additional method data, and the like. 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 a plurality of types of control command information and a plurality of authentication information transmitted to the peripheral unit in a time series as log data. The number of control command information and authentication information stored in the data storage unit 311 can be arbitrarily set. Moreover, the timing which memorize | stores in the data storage part 311 of control command information and authentication information can determine arbitrarily timings, such as after transmitting to a peripheral part, when it is decided. In this embodiment, for example, a case where a plurality of types of control command information such as a jackpot reach command, a jackpot start command, a jackpot command, a jackpot end command, and the like are stored in the data storage unit 311 as a history target will be described. Instead, only one kind of predetermined control command information can be stored.

  The data storage unit 311 stores three or more types of individual identification values arranged in a predetermined order. Each of the three or more types of individual identification values is a value used by the peripheral board 330 for authentication (individual value identification) of the main control board 310 (main control unit). Three or more types of individual identification values are different data. As an example of the individual identification value, there are a checksum of each of a plurality of types of predetermined areas in the ROM 212 of the main control unit 210, a predetermined unique value, and the like.

  The history generation method data indicates a history generation method used by the history data generation unit 313, is determined in advance with the peripheral board 330, and an initial value is set at the time of startup or the like and is stored in the data storage unit 311. Is done.

  The determination unit 312 corresponds to a determination unit of the present invention, and randomly determines the first individual identification value at a predetermined timing from among three or more types of individual identification values arranged in a predetermined order. The determination unit 312 randomly determines one leading individual identification value from among three or more types using, for example, random numbers. Note that three or more types of individual identification values arranged in a predetermined order are stored in advance in the ROM 212 or the like, and the relationship is a ring.

  The determination unit 312 stores three or more types of individual identification values in the data storage unit 311 in the order determined in advance for the three or more types of individual identification values from the determined first individual identification value. That is, the determination unit 312 rotates three or more types of individual identification values and stores them in the data storage unit 311. Specifically, an individual identification value assigned in order before the determined first individual identification value is attached to the tail so that the relationship becomes a ring. Thus, the storage order of the present invention means the order in which three or more types of individual identification values are rotated and stored in the data storage unit 311.

  The history data generation unit 313 corresponds to the history data generation means of the present invention, and generates history data indicating the history of control command information transmitted from the main control board 310 to the peripheral board (peripheral part) 330, as a predetermined history generation. Generate by method. The history data generation unit 313, for example, at a predetermined generation timing such as an arbitrary timing from generation (determination) of control command information to transmission to the peripheral part of the control command information in the pachinko gaming machine 100 at a predetermined generation timing History data is generated and stored based on the generation method and the control command information stored in the data storage unit 311. Then, the history data generation unit 313 calculates control command information for a predetermined number of transmissions based on a history generation method such as an error detection method, a predetermined encryption method, an exclusive OR, and the history data. Is generated. That is, in the history generation method, when generating history data for control command information, for example, the number of retrospective transmissions of transmitted single control command information, the retroactive range of multiple types of control command information, and the like are targets for generation of history data. Specifies control command information. When the history data generation unit 313 generates the history data as a checksum, the history data is a total value obtained by summing a single type of control command information for a plurality of times or a total of a plurality of control command information. Note that the history data can use, for example, control command information for one time such as the previous time or a predetermined number of times as it is, thereby simplifying processing when generating authentication information, which will be described later.

  The history data generation unit 313 according to the present embodiment will be described with respect to a case where the history data stored in the data storage unit 311 is updated to the generated history data and stored. In this case, the data storage unit 311 functions as history data storage means. Instead of this, for example, the history data may be stored in a register of the CPU 211, a predetermined storage area of the RAM 213, or the like. Also, the history data generating means and the storage means can be realized by dedicated hardware. If the history data generation unit 313 generates the same history data as the individual identification value, for example, the authentication information generation unit 316 does not generate authentication information having the history data, or the transmission unit 317 The authentication information including the history data is discarded without being transmitted. Alternatively, the history data generation unit 313 may be designed to generate history data having a value different from the individual identification value, or may be implemented in various different embodiments such as corresponding to the bit adjustment of the history data.

  The calculation unit 314 corresponds to the calculation means of the present invention, calculates different command values and random numbers possessed by each of a plurality of types of control command information by a predetermined calculation method, and stores the calculation results in the RAM 213 or the like. Remember. Examples of the calculation method include logical operation, four arithmetic operations, and calculation using a predetermined function.

  Here, each of the command values of the plurality of types of control command information is different data. The command value is data defining an individual identification value that can be extracted from three or more types of individual identification values of the main control board 310. In other words, the extraction range (extraction pattern) of individual identification values that can be extracted can be changed depending on the type of command value. Then, each of a plurality of types of command values according to the present embodiment is mask data that masks other than the desired bits of the random number value, so that the calculation unit 314 simply performs the calculation of the command value and the random number value, Change the valid bit of the numeric value and specify one computed value within that range. Then, each of a plurality of types of calculation values that are calculation results calculated by the calculation unit 314 is associated with one of three or more types of individual identification values on a one-to-one basis.

  For example, when the calculation method is a logical product (AND) operation, the calculation unit 314 performs an AND operation on the command value of the control command information, which is a fixed value, and a random value that randomly changes to obtain the calculated value. Ask. This calculated value is a value for randomly specifying one individual identification value among extractable individual identification values predetermined for three or more types of individual identification values. In addition, although the case where the calculating part 314 of a present Example is implement | achieved by software is demonstrated, it replaces with this and you may implement | achieve the same process with hardware, such as a logic time.

  The extraction unit 315 corresponds to the extraction unit of the present invention, and the calculation result of the calculation unit 314 is selected from the storage order of three or more types of individual identification values stored in the data storage unit (individual identification value storage unit) 311. One storage order corresponding to is extracted and stored in the RAM 213 or the like. That is, the calculation result of the calculation unit 314 and the storage order are associated one-to-one. With such a configuration, the extraction unit 315 extracts one storage order so that an individual identification value corresponding to the storage order can be specified by the data storage unit 311.

  In the present embodiment, the configuration in which the calculation unit 314 and the extraction unit 315 are separated from each other will be described. However, instead of this, the calculation unit 314 and the extraction unit 315 may be configured integrally. it can.

  The authentication information generation unit 316 corresponds to the authentication information generation unit of the present invention, and stores the individual identification values in the storage order extracted by the extraction unit 315 in the data storage unit 311 using a predetermined additional method. Authentication information is generated by adding to the history data. That is, the authentication information generation unit 316 extracts the individual identification value corresponding to the extracted storage order from the data storage unit 311, and generates authentication data that is a composite value obtained by adding the individual identification value to the history data by the addition method. Authentication information is generated. The addition method is a method for the main control board 310 to add an individual identification value to the history data, and is determined in advance with the peripheral board 330. The additional method is, for example, one predetermined calculation method among a plurality of types of calculation methods such as four arithmetic operations, XOR, XNOR, and the like, and the main control board 310 and the peripheral board 330 change the calculation method. The additional method data shown is stored in advance. Further, in the present embodiment, a case where an individual identification value is added to the latest history data will be described, but instead of this, for example, when a plurality of history data is stored in time series, a history a predetermined number of times before Various embodiments such as addition to data can be made.

  The transmission unit 317 corresponds to a transmission unit of the present invention, and each of the authentication information generated by the authentication information generation unit 316 and a plurality of types of control command information for controlling the peripheral substrate 330 is a peripheral substrate (peripheral portion). 330. Then, the transmission unit 317 of this embodiment transmits control command information from the main control board 310 to the peripheral board 330 as a control signal. For example, the transmission unit 317 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.

  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 reception unit 331, a peripheral side storage unit 332, a peripheral side history data generation unit 333, a specification unit 334, a first extraction unit 335, a storage order determination unit 336, and a second extraction unit. 337 and an authentication unit 338.

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

  The peripheral side storage unit 332 corresponds to expected value storage means of the present invention. As the peripheral storage unit 332, for example, a part of the ROM 242 and the RAM 243 (see FIG. 2) of the effect control unit 202 can be used. The peripheral storage unit 332 also has a storage area for storing a plurality of control command information and a plurality of authentication information received from the main control board 310 as log data in a time series manner, like the main control board 310. ing.

  The peripheral storage unit 332 has three or more types of individual identification values to be received from the main control board 310, that is, each of three or more types of individual identification values stored in the data storage unit 311 of the main control board 310. 3 or more types of expected values that match As a result, the peripheral board 330 matches any one of three or more expected values if the individual identification value added to the history data of the authentication information is a normal individual identification value. History data can be extracted from the authentication information based on the expected value. In addition, if the individual identification value of the authentication information is invalid, it does not match any of the three or more expected values, so the peripheral board 330 cannot extract regular history data from the authentication information based on the expected value.

  The peripheral storage unit 332 stores the same history generation method data and additional method data as the main control unit 201. The history generation method data indicates a history generation method used by the peripheral side history data generation unit 333, and an initial value is set at the time of startup or the like and stored in the peripheral side storage unit 332. The additional method data indicates the same additional method as that of the main control board 310 used by the authentication history data extraction unit 335.

  The peripheral side storage unit 332 has a storage area for storing storage order information indicating the storage order of three or more types of individual identification values in the main control board 310. The storage order information is generated as information having data indicating the storage order determined by the storage order determination unit 336 and stored in the peripheral side storage unit 332.

  The peripheral side history data generation unit 333 corresponds to the peripheral side history data generation means of the present invention, and the peripheral side history data indicating the history of the control command information received from the main control board 310 is the same as that of the main control board 310. Generate by history generation method. The peripheral side history data generation unit 333 receives the same history generation method and peripheral side as the main control board 310 at a predetermined peripheral side generation timing such as when receiving control command information from the main control board 310, after receiving the control command information. Peripheral history data is generated and stored based on the control command information stored in the storage unit 332. That is, the peripheral history data generation unit 333 calculates control command information for a predetermined number of receptions based on a history generation method such as an error detection method, a predetermined encryption method, an exclusive OR, etc. Generate data. Therefore, if the peripheral side history data receives only the control command information transmitted by the main control board 310, it will match the history data of the main control board 310. It can be determined that information is received.

  The peripheral history data generation unit 333 according to the present embodiment will be described with respect to the case where the peripheral history data stored in the peripheral storage unit 332 is updated to the generated peripheral history data and stored. In this case, the peripheral side storage unit 332 functions as a peripheral side history data storage unit. Instead of this, for example, the peripheral history data can be stored in the registers of the CPUs 241 and 281, the predetermined storage areas of the RAMs 243 and 283, and the like. In addition, the peripheral history data generating means and its storage means can be realized by dedicated hardware.

  The specifying unit 334 corresponds to the specifying unit of the present invention, and the main control board 310 stores three or more types of individual identification values based on the command value of the control command information received by the receiving unit 331 from the main control board 310. The storage order to be extracted is specified from the list. For example, when the main control board 310 has four storage orders of 0x00 to 0x03, if the command value indicates the first and third, the two storage orders of 0x00 and 0x02 are specified as extraction targets. Similarly, when the command value indicates only the first command, the specifying unit 334 specifies one storage order of 0x00 as an extraction target. In this way, the specifying unit 334 specifies any one of 0x00 to 0x03 as the extraction target storage order.

  The first extraction unit 335 corresponds to the first extraction unit of the present invention, and removes each of three or more types of expected values from the authentication information received by the reception unit 331 using the same addition method as that of the main control board 310. Three or more types of authentication history data are extracted and stored in the peripheral storage unit 332. That is, when there are four expected values, the first extraction unit 335 extracts four pieces of authentication history data. Accordingly, since the three or more types of authentication history data extracted by the first extraction unit 335 are values obtained by removing each of the three or more types of expected values from the authentication information (authentication data), the normal authentication information is received. If so, one of the three or more types of authentication history data extracted therefrom matches the history data of the main control board 310. Therefore, the expected value when the matched authentication history data is removed is a value that matches the individual identification value extracted by the main control board 310.

  The storage order determination unit 336 corresponds to the storage order determination unit of the present invention, and corresponds to authentication history data that matches the peripheral history data among the three or more types of authentication history data extracted by the first extraction unit 335. The storage order of the individual identification values in the main control board 310 is determined based on the individual identification values to be determined and the storage order specified by the specifying unit 334. That is, before the storage order determination unit 336 determines the storage order of the main control board 310, the storage order of the main control board 310 is unknown. After the storage order is determined, the authentication unit 338 authenticates the main control board 310. Is possible. As a result, the determination unit 312 of the main control board 310 can rotate while keeping the arrangement order of three or more types of individual identification values.

  The second extraction unit 337 corresponds to the second extraction unit of the present invention, and corresponds to each of one or a plurality of storage orders specified by the specification unit 334 in the storage order determined by the storage order determination unit 336. The expected value that matches the individual identification value is removed from the authentication information received by the receiving unit 331 by the same addition method as that of the main control board 310, and one or a plurality of authentication history data is extracted. The second extraction unit 337 extracts one or a plurality of authentication history data removed from the authentication information and stores them in the peripheral storage unit 332. That is, the second extraction unit 337 extracts two pieces of authentication history data when two expected values are specified, and three authentication values when three expected values are specified. Historical data is extracted. Accordingly, one or a plurality of authentication history data is a value obtained by removing one or a plurality of expected values from the authentication information (authentication data). Therefore, if normal authentication information is received, the extracted 1 Alternatively, one of the plurality of authentication history data is history data of the main control board 310. In addition, by extracting and using the expected value corresponding to the command value to extract the authentication history data from the authentication information, the authentication accuracy can be improved rather than extracting the authentication history data using all the expected values. It can be improved.

  The authentication unit 338 corresponds to the authentication unit of the present invention, and the latest peripheral side history data stored in the peripheral side storage unit 332 in the one or more authentication history data extracted by the second extraction unit 337. The main control board (main control unit) 310 is authenticated based on the determination result of whether or not there is a match. If there is a match with the peripheral history data, the authentication unit 338 can determine that the history data of the received authentication information is valid, and thus establish authentication. In addition, when the authentication unit 338 does not match the peripheral history data, for example, it is considered that the history data and the peripheral history data are different due to fraud, or that incorrect authentication information is used. Therefore, since the history data or the individual identification value of the received authentication information can be determined to be invalid, authentication is not established. That is, the authentication unit 338 authenticates the main control board 310 (main control unit 201) based on communication continuity (history data).

  In the present embodiment, a case will be described in which after the second extraction unit 337 extracts a plurality of authentication history data, the authentication unit 338 compares each of the plurality of authentication history data with the peripheral history data. Instead of this, for example, every time the second extraction unit 337 extracts one piece of authentication history data, the authentication unit 338 may compare with the peripheral side history data.

  The peripheral board 330 configured in this way, after determining the storage order of the three or more types of individual identification values of the main control board 310, according to each of a plurality of types of control command information received from the main control board 310, Predetermined processing in the pachinko gaming machine 100 is performed. The peripheral board 330 performs the predetermined process corresponding to the control command information indicated by the received control signal when the authentication unit 338 is authenticated, and notifies when the authentication is not established. Note that the predetermined processing is processing corresponding to each of a plurality of types of control command information from the main control unit 201 in the pachinko gaming machine 100, for example, discontinuation processing, jackpot reach processing, jackpot start processing, jackpot round processing , Jackpot end processing, and the like.

  In the present embodiment, a case where the CPU 211 of the main control board 310 functions as a first computer and each of the CPUs 241 and 281 of the peripheral board 330 functions as a second computer will be described. The ROM 212 of the main control board 310 causes the first computer to function as various means such as determination means, history data generation means, calculation means, extraction means, authentication information generation means, and transmission means in the claims. The main control side authentication program is stored. In addition, each of the ROMs 242 and 282 of the peripheral board 330 includes the receiving unit, the peripheral side history data generating unit, the specifying unit, the first extracting unit, the storage order determining unit, the second extracting unit, and the second computer. The peripheral side authentication program for functioning as various means such as authentication means 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 situation of the game balls for each winning opening to the winning ball control unit 203 as control command information. The winning ball control unit 203 pays out the number of winning balls corresponding to the winning situation in accordance with the control command information output from the main control unit 201.

  The main control unit 201 outputs corresponding control command information 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 and stop. The main control unit 201 outputs the corresponding control command information 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. Then, control for opening the special winning opening 109 is performed. 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 performing specific driving for various types of accessories and correcting 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 FIGS. 4 to 9, “send a command” means “send a control signal including data (control command information) indicating the command”. The presence or absence of data is not considered.

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

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

  In step S <b> 403, the main control unit 201 refers to the unlottery winning number data stored in the ROM 212 or the RAM 213, and determines whether or not the unlotted winning number is zero. The number of undrawn winnings is the number obtained by subtracting the number of times that a lottery corresponding to the winning ball has been performed (number of already drawn lots) from the number of winning balls detected at the start winning opening 105 (number of winnings). If the main control unit 201 determines that the number of undrawn winning prizes is not zero (S403: No), the process proceeds to step S410. On the other hand, if the main control unit 201 determines that the number of undrawn winning prizes is zero (S403: Yes), in step S404, the main control unit 201 measures the time elapsed since the demonstration was started, and proceeds to the process of step S405. To do.

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

  The various commands in FIGS. 4 and 5 described above correspond to the control command information of the present invention, and each time the main control board 310 transmits the various control command information, the control command information is stored in the data storage unit 311 as a history. I remember it. In response to the storage of the control command information, the main control board 310 updates the history data in the data storage unit 311. Note that the history data is updated when a plurality of types of authentication information is generated, so that the processing load on the main control board 310 can be reduced. In addition, every time the peripheral board 330 receives various control command information, the peripheral board 330 stores the control command information in the peripheral side storage unit 332 as a history, and updates the peripheral side history data in the peripheral side storage unit 332.

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

  First, the symbol variation process by the effect control unit 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 determining 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 determining that the symbol stop command has been received (S706: Yes), the effect control unit 202 transmits the effect stop command to the lamp control unit 251 and the voice control unit 252 in step S707, and according to this flowchart. End the process.

  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, control command information 1010 indicated by a normal control signal has a command value 1001 and accompanying data 1002. The command value 1001 is the command value described above, and 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 command value 1001, and is data necessary for processing based on the command value 1001 such as the number of winning game balls, for example.

(Authentication information data format)
Next, an example where an authentication information signal different from the control signal 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. An example of the identification data is one type of authentication command. For example, hexadecimal values such as 0xA0 and 0xB0 are set. Thereby, the peripheral part can identify the authentication information 1020 based on the identification part 1021. The authentication command is differentiated from the command value 1001 by using a command value different from the command value of the command value 1001 described above.

  In the data part 1022, authentication data obtained by adding an individual identification value to the above-described history data is set. In this embodiment, the case where the authentication information 1020 includes the identification unit 1021 and the data unit 1022 will be described, but instead, the identification unit 1021 is excluded and the authentication information 1020 is configured only by the data unit 1022. You can also.

(Example of relationship between three or more types of individual identification values and storage order)
As shown in FIG. 12, the main control board 310 stores four individual identification values UA, UB, UC, and UD as a part of the program. In the main control board 310, the order of the individual identification values UA, UB, UC, UD is determined in advance, and the relationship is a ring. In this embodiment, the individual identification value UA is set to 0x11, the individual identification value UB is set to 0x33, the individual identification value UC is set to 0x55, and the individual identification value UD is set to 0x77.

  The main control board 310 sets the first individual identification value from among the four individual identification values UA, UB, UC, UD at predetermined timings such as when the pachinko gaming machine 100 is started or reset. Make a decision. That is, the main control board 310 rotates the four individual identification values UA, UB, UC, and UD arranged in order at every predetermined timing to switch the storage order in the data storage unit 311 at random.

  Each of the four storage orders is defined as relative addresses 0x00, 0x01, 0x02, and 0x03 in the data storage unit 311. When the main control board 310 determines that the individual identification value UA is the head, the relative address 0x00 of the data storage unit 311 is stored in the storage order of the individual identification values UA, UB, UC, and UD, as shown in Case 1 of FIG. Store at address ~ 0x03. Further, when the main control board 310 determines that the individual identification value UB is the head, as shown in case 2 of FIG. 13, the relative address 0x00 of the data storage unit 311 in the storage order of the individual identification values UB, UC, UD, and UA. Store at address ~ 0x03. When the main control board 310 determines that the individual identification value UC is the head, as shown in case 3 in FIG. 13, the relative address 0x00 of the data storage unit 311 in the storage order of the individual identification values UC, UD, UA, and UB. Store at address ~ 0x03. Further, when the main control board 310 determines that the individual identification value UD is the head, as shown in Case 4 of FIG. 13, the relative address 0x00 of the data storage unit 311 in the storage order of the individual identification values UD, UA, UB, and UC. Store at address ~ 0x03.

  Therefore, as shown in FIG. 13, the correspondence between the relative addresses 0x00 to 0x03 and the individual identification values UA, UB, UC, and UD is switched according to the first individual identification value determined by the main control board 310 at random. Therefore, even if it is the same relative address (storage order), the corresponding individual identification value can be changed. Therefore, even if the main control board 310 stores a limited number of individual identification values, More than that number of storage patterns can be used, and illegal analysis of a limited number of individual identification values can be made difficult.

(Example of command value setting for control command information)
The command value 1001 of the control command information 1010 is a unique value that can identify the control command information 1010. The command value 1001 defines different numbers of individual identification values to be extracted, which are determined in advance for three or more individual identification values, by calculating a logical product with a random number value. This is a value for specifying one individual identification value. The command value 1001 is set, for example, between the time when the pachinko gaming machine 100 is designed and the time when it is manufactured. The command value 1001 of this embodiment is mask data for extracting (validating) a desired bit of the random value by the logical product operation. For example, when extracting the lower 1 bit of the random value, the command value is 0x01, and when extracting the lower 2 bits of the random value, the command value is 0x03.

  Thereby, when the logical product of the command value 1001 and the random number value is calculated, a calculated value corresponding to a desired bit of the random value defined by the command value 1001 can be obtained. Therefore, each of the plurality of types of command values 1001 is set as different mask data from which arbitrary bits that always change the random number value can be extracted.

  In addition, although the random number value of an Example demonstrates the case where the main control board 310 produces | generates a random number value when the main control board 310 calculates with the command value 1001 of the control command information 1010, it replaces with this, for example, The jackpot determination random number used in the pachinko gaming machine 100, other random numbers, or the like may be used.

(Example of relationship between calculated value and individual identification value)
In the present embodiment, the above-described relative address is a calculated value obtained by calculating the logical product of the command value and the random number value, and one individual identification value can be derived from the calculated value. Note that when there are five or more individual identification values, the operation values after 0x04 can be handled by repeating the relative addresses 0x00 to 0x03, or by increasing the relative addresses.

(Operation example of command value and random value)
Next, an example of calculating the logical product of the command value and the random value will be described. It is assumed that the command value and the random number value are 8 bits, and the control command information 1010 is four types of control commands CA, CB, CC, and CD.

  First, as shown in FIG. 14, the command value of the control command CA is 0x00, the command value of the control command CB is 0x01, the command value of the control command CC is 0x02, and the command value of the control command CD is 0x03. The four individual identification values will be described on the assumption that they are stored in the data storage unit 311 in the storage order of the individual identification values UA, UB, UC, and UD as shown in case 1 of FIG.

  When the logical product of the command value (0x00) of the control command CA and the random value is calculated, the value of the random value becomes invalid, and the calculated value is only one (fixed) 0x00. Therefore, in the case of the calculated value of the control command CA and the random number value, the relative address (storage order) that can be selected from the above-described relative addresses 0x00 to 0x03 is 0x00, and therefore, the four individual identification values UA, UB, UC , Only one individual identification value UA is extracted from the UD.

  When the logical product of the command value (0x01) of the control command CB and the random value is calculated, only the lower bit is valid for the random value, and the calculated value is either 0x00 or 0x01 depending on the random value that changes randomly. One can be specified. Therefore, in the case of the calculated value of the control command CB and the random number value, the relative address (storage order) that can be selected from the above-described relative addresses 0x00 to 0x03 is 0x00 or 0x01, so that the four individual identification values UA and UB , UC, UD, two individual identification values UA, UB corresponding (stored) to the relative address are extractable individual identification values.

  When the logical product of the command value (0x02) of the control command CC and the random value is calculated, only the lower 2nd bit of the random value is valid, and the calculated value is either 0x00 or 0x02 depending on the random value that changes randomly. One can be specified. Accordingly, in the case of the calculated value of the control command CC and the random number value, the relative address (storage order) that can be selected from the above-described relative addresses 0x00 to 0x03 is 0x00 or 0x02, and therefore, the four individual identification values UA and UB , UC, UD, two individual identification values UA, UC corresponding (stored) to the relative address are extractable individual identification values. The control command CC is different in that the number of individual identification values that can be extracted matches the control command CB, but the individual identification value UB that can be extracted from the control command CB cannot be extracted.

  When the logical product of the command value (0x03) of the control command CD and the random value is calculated, all the lower 2 bits of the random value are valid, and the calculated value is any one of 0x00 to 0x03 depending on the random value that changes randomly. Can be specified. Therefore, in the case of the calculated value of the control command CD and the random value, the relative address (storage order) that can be selected from the above-described relative addresses 0x00 to 0x03 is any one of 0x00 to 0x03, so four individual identifications are made. All of the values UA, UB, UC and UD are extractable individual identification values. That is, the control command CD differs from the control commands CA, CB, and CC in the number of individual identification values that can be extracted.

  As described above, only by calculating the command value and random number value of the control commands CA, CB, CC, CD, one of the four individual identification values UA, UB, UC, UD, or a plurality of individual identification values The number of objects to be extracted can be changed in association with the desired control command information 1010, and the individual identification value can be extracted at random from the random number value.

  In the present embodiment, a case where four control commands UA, UB, UC, and UD are used will be described. However, instead of this, five or more control command information 1010 may be used. In that case, it can be set as various different embodiments, such as increasing the number of individual identification values and associating a plurality of control commands with one individual identification value.

  In the present invention, the control commands CA, CB, CC, and CD having the command values described above are selected from a plurality of existing control commands, for example, at the time of designing or manufacturing the pachinko gaming machine 100. By using them, it is possible to prevent the above-described new addition of command values.

  As shown in FIG. 15, when the command value of the existing control command CA is 0xX0, the command value of the control command CB is 0xX1, the command value of the control command CC is 0xX2, and the command value of the control command CD is 0xX3, In the embodiment, when the four individual identifications UA, UB, UC, and UD are accessed, an address generation process for adjusting the address range is performed. Note that “X” in the command value means that any of hexadecimal numbers 0 to F may be used. Further, the control command information 1010, the effective bit of the random value, the extractable range, and the selectable address in FIG. 15 are the same as those described in FIG.

  In that case, as an example of the address generation process, the lower 4 bits are extracted by a bit mask or the like from the operation value by the logical product of the command value and the random number value, so that the value matching the above-described relative address is obtained. Generate. Alternatively, the address generation processing may be an embodiment in which the relative address is generated using a calculation value of a command value and a random value, a conversion table, and the like.

(Example of additional method)
Next, as the above-described method of adding history data to the individual identification value, for example, one arithmetic method among four arithmetic operations, XOR, XNOR and the like is determined in advance in the pachinko gaming machine 100. When the additional method is determined as “+” of the four arithmetic operations, the main control board 310 sets authentication data obtained by adding the individual identification value extracted as described above to the history data in the data portion 1022 and authentication information. 1020 is generated. On the other hand, the peripheral board 330 extracts one or a plurality of authentication history data by subtracting one or a plurality of expected values specified as described above from the data set in the data portion 1022 of the received authentication information 1020. . Since the three or more types of expected values coincide with the three or more types of individual identification values, one of the one or more authentication history data extracted by removing the expected value from the peripheral board 330 is one. Since normal history data can be extracted, it should match the peripheral history data.

  In addition, when the additional method is determined as “−” of the four arithmetic operations, the main control board 310 sets authentication data obtained by subtracting the individual identification value extracted as described above from the history data in the data portion 1022 and authentication information. 1020 is generated. On the other hand, the peripheral board 330 extracts one or more authentication history data by adding one or more expected values specified as described above from the data set in the data portion 1022 of the received authentication information 1020. . Even if it implements in this way, since three or more types of expected values coincide with three or more types of individual identification values, if the peripheral board 330 adds the expected values, one or more extracted authentication values are used. Since one regular history data can be extracted from the history data, it should match the peripheral history data.

  Therefore, any calculation method may be used as long as the additional method is a calculation method in which the peripheral substrate 330 can perform reverse calculation. In this embodiment, the case where the main control board 310 adds only the individual identification value to the history data will be described, but instead of this, a predetermined additional value between the individual identification value and the peripheral board 330 is used. Different embodiments may be made, such as adding both data (eg, predetermined values).

(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. It is assumed that the three or more types of individual identification values are the above-described four individual identification values UA, UB, UC, and UD.

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes the authenticated side processing shown in FIG. 16, and in step S1201, for example, when the pachinko gaming machine 100 is started or reset, It is determined whether or not it is a decision timing (timing) such as a predetermined date and time. If the main control unit 201 determines that it is not the determination timing (S1201: No), the main control unit 201 proceeds to the process of step S1204. On the other hand, when the main control unit 201 determines that it is the determination timing (S1201: Yes), it is necessary to determine the storage order of the individual identification values, and thus the process proceeds to step S1202.

  In step S1202, the main control unit 201 obtains a random number value and randomly determines a leading individual identification value from the four individual identification values. In step S1203, the main control unit 201 determines from the determined leading individual identification value, The four individual identification values are stored in the data storage unit 311 in the order (order) of the four individual identification values, and then the process proceeds to step S1204. By this processing, four individual identification values are rotated and stored in the data storage unit 311.

  In step S1204, the main control unit 201 determines whether the generation of the control command information 1010 has been detected based on the control command information 1010 stored in the data storage unit 311. If the main control unit 201 determines that the generation of the control command information 1010 has not been detected (S1204: No), the main control unit 201 proceeds to the process of step S1212. On the other hand, if the main control unit 201 determines that the generation of the control command information 1010 is detected (S1204: Yes), the history generation method data and the history generation method data in the data storage unit 311 are generated in step S1205. Based on the target control command information 1010, history data is generated and stored in the data storage unit 311. Thereafter, the process proceeds to step S1206.

  In step S1206, the main control unit 201 obtains a random number value, performs an operation based on a logical product of the command value 1001 of the control command information 1010 and the random number value, stores the operation result in the RAM 213, etc., and then in step S1207. Proceed to processing. In step S1207, the main control unit 201 extracts one individual identification value in the storage order corresponding to the calculation result (relative address) from the four individual identification values UA, UB, UC, and UD, and stores the RAM 213. Etc., and then the process proceeds to step S1208.

  In step S1208, the main control unit 201 generates authentication data (composite value) in which the extracted individual identification value is added to the latest history data stored in the data storage unit 311 by the addition method, and then the step The process proceeds to S1209. In step S1209, the main control unit 201 generates authentication information 1020 in which the authentication command is set in the identification unit 1021 and the authentication data is set in the data unit 1022, and is stored in the data storage unit 311. Then, the process proceeds to step S1210. Note that the timing for generating the authentication information 1020 of the main control unit 201 can be set to a predetermined authentication timing or the like when the individual identification value is generated.

  In step S1210, the main control unit 201 encrypts the authentication information 1020 generated this time with a predetermined encryption method with the peripheral unit, and in step S1211, the encryption information 1020 is transmitted at a predetermined transmission timing. An authentication information signal is generated based on the converted authentication information 1020 and transmitted from the transmission unit 317 to the peripheral unit, and then the process proceeds to step S1212. If encryption is not required between the main control unit 201 and the peripheral unit, the processing in step S1210 is deleted, and the authentication information 1020 is transmitted to the peripheral unit as it is.

  In step S1212, 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 (S1212: 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 (S1212: Yes), the process according to this flowchart ends.

  Next, the authentication information signal reception processing procedure performed by the peripheral CPUs 241 and 281 (second computer) will be described with reference to the flowcharts of FIGS. 17 and 18.

  First, when the peripheral unit executes the storage order determination process shown in FIG. 17 in response to, for example, activation or reset of the pachinko gaming machine 100, the main control unit 201 refers to the peripheral side storage unit 332 in step S1301. Control command information 1010 received from step S1302, and then the process proceeds to step S1302. In step S1302, based on the command value 1001 of the control command information 1010, the peripheral unit determines that one or more individual identification values to be extracted by the main control unit 201 from three or more types of individual identification values. The storage order is specified, the specified result is stored in the peripheral storage unit 332, etc., and then the process proceeds to step S1303.

  In step S <b> 1303, the peripheral unit determines whether the receiving unit 331 has received authentication information (authentication information signal) 1020 from the main control unit 201. When it is determined that the authentication information 1020 has not been received (S1303: No), the peripheral unit waits for reception of the authentication information 1020 by repeating this determination process. On the other hand, if it is determined that the authentication information 1020 has been received (S1303: Yes), the peripheral unit proceeds to the process of step S1304.

  In step S1304, the peripheral unit decrypts the received authentication information 1020 with a decryption method corresponding to the encryption method of the main control unit 201, extracts authentication data from the data unit 1022 of the authentication information 1020, and One or a plurality of authentication history data obtained by removing one or a plurality of expected values corresponding to the individual identification values of one or a plurality of storage orders indicated by the identification result from the authentication data based on the additional method data is stored in the peripheral side The information is stored in the unit 332, and then the process proceeds to step S1305. If encryption is not required between the main control unit 201 and the peripheral unit, the decryption process in step S1304 is deleted.

  In step S1305, the peripheral unit is based on the individual identification value corresponding to the authentication history data that matches the peripheral history data among the extracted one or more authentication history data and the specified storage order. Then, the storage order of the individual identification values in the main control unit 201 is detected, it is determined whether or not the storage order is determined from the detection result, the determination result is set in the determination flag, and the peripheral storage unit 332 or the like is set. Then, the process proceeds to step S1306. The confirmation flag is cleared in the omitted initial process at the time of startup.

  In step S1306, the peripheral unit determines whether or not the storage order is determined based on the determination flag. If it is determined that the storage order is not fixed (S1306: No), the peripheral unit returns to the process of step S1303 and waits for reception of the next authentication information 1020. That is, the storage order is detected in combination with the next authentication information 1020. On the other hand, when it is determined that the storage order is fixed (S1306: Yes), the peripheral unit proceeds to the process of step S1307.

  In step S1307, the peripheral unit determines the correspondence between the three or more types of individual identification values in the main control unit 201 and the storage order in the data storage unit 311 and enters the authenticable state of the main control unit 201 based on the authentication information 1020. After that, the process according to this flowchart is terminated.

  Subsequently, when executing the authentication-side process shown in FIG. 18, the peripheral unit determines whether or not control command information 1010 has been received from the main control unit 201 with reference to the peripheral-side storage unit 332 in step S1401. . If it is determined that the control command information 1010 has not been received (S1401: No), the peripheral unit proceeds to the process of step S1404.

  On the other hand, if it is determined that the peripheral unit has received the control command information 1010 (S1401: Yes), in step S1402, the history generation method data and the history in the peripheral storage unit 332 are the same as the main control unit 201. Based on the control command information 1010 to be generated by the generation method, peripheral history data is generated and stored in the peripheral storage unit 332, and then the process proceeds to step S1403. In step S1403, based on the command value 1001 of the control command information 1010, the peripheral unit stores the order in which one or more individual identification values to be extracted from the three or more types of individual identification values by the main control unit 201 are stored. , And the identification result is stored in the peripheral storage unit 332 and the like, and then the process proceeds to step S1404.

  In step S <b> 1404, the peripheral unit determines whether the receiving unit 331 has received authentication information (authentication information signal) 1020 from the main control unit 201. When it is determined that the authentication information 1020 has not been received (S1404: No), the peripheral unit proceeds to the process of step S1411. On the other hand, if the peripheral unit determines that the authentication information 1020 has been received (S1404: Yes), the process proceeds to step S1405.

  In step S1405, the peripheral unit decrypts the received authentication information 1020 with a decryption method corresponding to the encryption method of the main control unit 201, extracts authentication data from the data unit 1022 of the authentication information 1020, and One or more authentication history data obtained by removing one or more expected values that match the individual identification value in the storage order indicated by the specific result from the authentication data based on the additional method data are stored in the peripheral storage unit 332 Then, the process proceeds to step S1406. If encryption is not required between the main control unit 201 and the peripheral unit, the decryption process in step S1405 is deleted.

  In step S 1406, the peripheral unit compares the extracted one or more authentication history data with the latest peripheral history data stored in the peripheral storage unit 332, and the authentication history that matches the peripheral history data. The determination result as to whether or not data exists is stored in the peripheral storage unit 332 and the like, and then the process proceeds to step S1407.

  If the peripheral unit determines in step S1407 that the matching authentication history data exists (S1407: Yes), the history data of the authentication information 1020 matches the peripheral history data, and the continuity of communication is valid. Therefore, in step S1408, the authentication of the main control unit 201 is established, and then the process proceeds to step S1411. On the other hand, if it is determined that the matching history data for authentication does not exist (S1407: No), the continuity of communication is not valid or the authentication information is invalid in step S1409. In step S1410, for example, a notification signal is output from the speaker 262 (see FIG. 2) or the like, and then the process proceeds to step S1411.

  In step S1411, the peripheral unit determines whether or not the pachinko gaming machine 100 is powered off. If the peripheral portion determines that the power is not turned off (S1411: No), the processing returns to step S1401, and a series of processing is repeated. On the other hand, when it is determined that the power source is turned off (S1411: Yes), the peripheral unit ends the process according to this flowchart.

  In this embodiment, a case has been described in which the peripheral portion extracts all of the plurality of authentication history data, and then collectively compares them with the peripheral history data. However, instead of this, one authentication history data is extracted. It can also be an embodiment in which it is compared with the peripheral history data each time.

(Example of authentication process)
Next, in the pachinko gaming machine 100, the main control board 310 and the peripheral board 330 use the above-described four individual identification values UA, UB, UC, UD and the expected values VA, VB, VC, VD. This will be described with reference to the drawings of FIGS.

  First, as a precondition, the main control board 310 sets the four individual identification values UA, UB, UC, and UD in the arrangement order, and the addition method is “+”. On the other hand, the peripheral board 330 stores four expected values VA, VB, VC, VD that match the individual identification values UA, UB, UC, UD of the main control board 310 in the peripheral storage unit 332 in advance. It is stored that the addition method of the control board 310 is “+”. That is, the peripheral board 330 stores “−”, which is an addition method opposite to the main control board 310. Further, the control command information 1010 has the same configuration as that shown in FIG.

  In FIG. 19, the main control board 310, which is the person to be authenticated, randomly selects the head from among the four individual identification values UA, UB, UC, UD in response to, for example, activation or reset of the pachinko gaming machine 100. When the identification value UA is determined (S1501), as shown in case 1 of FIG. 13, the data storage unit 311 sequentially stores the individual identification values UA in the order of the four individual identification values UA, UB, UC, and UD. Store (S1502).

  When the main control board 310 transmits the control command CA to the peripheral board 330, the main control board 310 stores the control command CA in the data storage unit 311 (S1503). The main control board 310 generates history data based on the transmitted control command CA and the history generation method, and stores the history data in the data storage unit 311 (S1504). The main control board 310 calculates a logical product of the command value 1001 (0x00) of the control command CA and a random value, and stores the calculation result of 0x00 in the RAM 213 or the like (S1505). Since the calculation result is 0x00, the main control board 310 extracts the individual identification value UA (see case 1 in FIG. 13) whose relative address is 0x00 and stores it in the RAM 213 or the like (S1506).

  On the other hand, when the peripheral board 330 receives the control command CA, the peripheral board 330 stores the received control command CA in the peripheral-side storage unit 332 and performs a predetermined process corresponding to the control command CA (S1551). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command CA and history generation method, and stores it in the peripheral side storage unit 332 (S1552). Since the command value 1001 of the control command CA is 0x00, the peripheral board 330 specifies that the extraction target storage order of the main control board 310 is 0x00 (S1553).

  Thereafter, the main control board 310 generates authentication information 1020 having authentication data C0 obtained by adding (adding) the extracted individual identification value UA to the latest history data, and transmits it to the peripheral board 310 (S1507). On the other hand, the peripheral board 330 subtracts (removes) each of the four expected values VA, VB, VC, VD from the authentication data C0 of the received authentication information 1020, and the authentication history data C0-VA, C0-VB. , C0-VC, C0-VD are extracted, and it is determined whether or not any of them matches the latest peripheral history data. Then, since the peripheral substrate 330 matches the authentication history data C0-VA, the individual identification value UA that matches the expected value VA is detected as the specified storage order is 0x00 (first) and stored. It is determined that the order is the order of individual identification values UA, UB, UC, UD (S1554).

  As shown in FIG. 13, the control command CA can select only 0x00 as the relative address from the command value, so the correspondence between the storage order and the individual identification value is determined by one authentication information 1020. However, when a plurality of storage orders can be selected like the control commands CB, CC, and CD, a plurality of authentication information 1020 is received and the storage order is determined.

  For example, in the case of the control command CB, since the relative address of the selection target is either 0x00 or 0x01, the relationship between 0x00 and 0x01 and the individual identification value is detected based on a plurality of authentication information 1020. One storage order is determined.

  When the main control board 310 transmits the control command CA to the peripheral board 330 according to the operation of the pachinko gaming machine 100, the main control board 310 stores the control command CA in the data storage unit 311 (S1508). Then, the main control board 310 generates history data based on the transmitted control command CA and the history generation method and stores it in the data storage unit 311 (S1509). Then, the main control board 310 calculates the logical product of the command value 1001 (0x00) of the control command CA and the random value, and stores the calculation result of 0x00 in the RAM 213 or the like (S1510). Since the calculation result is 0x00, the main control board 310 extracts the individual identification value UA (see case 1 in FIG. 13) whose relative address is 0x00 (storage order) and stores it in the RAM 213 or the like (S1511). .

  On the other hand, when the peripheral board 330 receives the control command CA, the peripheral board 330 stores the received control command CA in the peripheral storage unit 332 and performs a predetermined process corresponding to the control command CA (S1555). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command CA and history generation method, and stores it in the peripheral side storage unit 332 (S1556). Since the peripheral board 330 has a command value 1001 of the control command CA of 0x00, 0x00 in the storage order is an extractable storage order of the main control board 310, and the individual identification value UA corresponding to the 0x00 is specified. (1557).

  Thereafter, the main control board 310 generates authentication information 1020 having authentication data C1 obtained by adding (adding) the extracted individual identification value UA in the storage order to the latest history data, and transmits it to the peripheral board 310 (S1512). . On the other hand, the peripheral board 330 subtracts (removes) the expected value VA corresponding to the identified individual identification value UA from the authentication data C1 of the received authentication information 1020 to extract the authentication history data C1-VA, Based on whether the authentication history data C1-VA matches the latest peripheral history data, authentication is performed based on the continuity of communication of the control command information 1010 with the main control board 310 (S1558).

  When the main control board 310 transmits the next control command CD to the peripheral board 330, the main control board 310 stores the control command CD in the data storage unit 311 (S1513). Then, the main control board 310 generates history data based on the transmitted control command CD and the history generation method and stores it in the data storage unit 311 (S1514). When the acquired random number value is 0x02, the main control board 310 performs a logical product operation of the command value 1001 (0x03) of the control command CD and the random value (0x02), and the operation result of 0x02 is stored in the RAM 213. (S1515). Since the calculation result is 0x02, the main control board 310 extracts the individual identification value UC (see case 1 in FIG. 13) whose relative address is 0x02 (storage order) and stores it in the RAM 213 or the like (S1516). .

  On the other hand, when receiving the control command CD, the peripheral board 330 stores the received control command CD in the peripheral storage unit 332 and performs a predetermined process corresponding to the control command CD (S1559). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command CD and history generation method, and stores it in the peripheral side storage unit 332 (S1560). In the peripheral board 330, since the command value 1001 of the control command CD is 0x03, all of the storage orders are the storage orders that can be extracted from the main control board 310, and the four individual identification values UA, UB, UC, UD All are specified that the main control board 310 can be extracted (S1561).

  Thereafter, the main control board 310 generates authentication information 1020 having authentication data C2 obtained by adding (adding) the extracted individual identification value UC to the latest history data, and transmits it to the peripheral board 310 (S1517). On the other hand, the peripheral board 330 subtracts each of the expected values VA, VB, VC, VD corresponding to the identified four individual identification values UA, UB, UC, UD from the authentication data C2 of the received authentication information 1020. (Removes) authentication history data C2-VA, C2-VB, C2-VC, C2-VD, and the authentication history data C2-VA, C2-VB, C2-VC, C2-VD and the latest Authentication is performed based on the continuity of communication of control command information with the main control board 310 based on whether or not the peripheral history data of the two match (S1562).

  When the main control board 310 transmits the next control command CB to the peripheral board 330, the main control board 310 stores the control command CB in the data storage unit 311 (S1518). The main control board 310 generates history data based on the transmitted control command CB and the history generation method, and stores the history data in the data storage unit 311 (S1519). When the acquired random number value is 0x01, the main control board 310 performs an AND operation between the command value 1001 (0x01) of the control command CB and the random value (0x01), and the operation result of 0x01 is stored in the RAM 213. (S1520). Since the calculation result is 0x01, the main control board 310 extracts the individual identification value UB (see case 1 in FIG. 13) whose relative address is 0x01 (storage order) and stores it in the RAM 213 or the like (S1521). .

  On the other hand, when the peripheral board 330 receives the control command CB, the peripheral board 330 stores the received control command CB in the peripheral-side storage unit 332 and performs a predetermined process corresponding to the control command CB (S1563). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral history data based on the received control command CB and history generation method, and stores it in the peripheral storage section 332 (S1564). Since the command value 1001 of the control command CB is 0x01 in the peripheral board 330, 0x00 and 0x01 in the storage order are the storage orders that can be extracted from the main control board 310, and the individual identification corresponding to the 0x00 and 0x01 The values UA and UB are specified (S1565).

  Thereafter, the main control board 310 generates authentication information 1020 having authentication data C3 obtained by adding (adding) the extracted individual identification value UB to the latest history data, and transmits it to the peripheral board 310 (S1522). On the other hand, the peripheral board 330 subtracts (removes) the expected values VA and VB corresponding to the two identified individual identification values UA and UB from the authentication data C3 of the received authentication information 1020. Data C3-VA and C3-VB are extracted, and control command information with the main control board 310 is determined based on whether or not the authentication history data C3-VA and C3-VB match the latest peripheral history data. Authentication based on the continuity of the communication 1010 is performed (S1566). Thereafter, the same processing is performed.

  According to the pachinko gaming machine 100 described above, the main control board 310 stores three or more types of individual identification values whose arrangement order is predetermined in a storage order that is randomly rotated, and the existing control command information By simply calculating the command value and random number value of 1010, one individual identification value 1001 is extracted from three or more types of individual identification values from the storage order corresponding to the calculation result, and the extracted individual identification value is Since the authentication information 1020 added to the history data is generated and transmitted to the peripheral board 330, even if the peripheral board 330 uses the history data of the authentication information 1020 for authentication of the main control board 310, it is added to the history data. Since the identified individual identification value 1020 changes irregularly depending on the random number value, the regularity of the authentication information 1020 is lost, and illegal analysis of the authentication information 1020 is prevented. It can be expected. In addition, since the storage order of the three or more types of individual identification values on the main control board changes randomly, the individual identification values extracted based on the storage order change. It can be changed in a more complicated manner, and can contribute to prevention of unauthorized analysis of the authentication information 1020. In addition, the peripheral board 330 determines the storage order of three or more types of individual identification values in the main control board 310 from the storage order specified based on the control command information 1010 and the authentication history data extracted from the authentication information 1020. Therefore, if the peripheral board 330 stores only the arrangement order of three or more types of individual identification values, the storage order changed by the main control board 310 can be detected and determined, so that there are three types. Unauthorized analysis of the individual identification value and the authentication information 1020 can be made difficult. Moreover, the peripheral board 330 extracts the authentication history data from the authentication information 1020 using only the expected value corresponding to the command value 1001 of the control command information 1010 for the three or more types of expected values, and the extracted authentication data Since the authentication of the main control board 310 is performed based on the determination result of whether or not the history data and the peripheral side history data match, the extraction target of the main control board 310 is determined by a plurality of different command values 1001. Even when the pattern is changed, the main control board 310 does not need to determine (recognize) the change, and the peripheral board 330 can bear the processing related to the authentication of the main control board 310. The pattern to be extracted can be switched in cooperation with the value 1001, and fraud analysis on the authentication information 1020 is made more difficult. Rukoto can. Furthermore, since the main control board 310 can store three or more types of individual identification values in advance, it is not necessary to perform complicated calculations when generating the authentication information 1020, and the processing load on the main control board 310 is increased. Can be prevented. On the other hand, since the peripheral board 330 is configured to confirm and authenticate the communication continuity of the control command information 1010 based on the history data, it can detect unauthorized communication switching due to unauthorized control command information. It can contribute to prevention of unauthorized communication switching. In addition, since the peripheral substrate 330 extracts the authentication history data from the authentication information 1020 using one or a plurality of expected values, the authentication history data and the history data are added when the regular individual identification value is not added to the history data. Since the peripheral history data does not match, fraud can be reliably detected. Further, for example, when an illegal board or the like intervenes between the main control board 310 and the peripheral board 330, the processing load must be increased because the analysis load on the illegal board increases. Increasing the degree can contribute to deterring the production of illegal substrates. Therefore, it is possible to check the communication continuity of the control command information 1010 and to make the analysis of the authentication information 1020 used for authentication difficult by using an existing configuration and minimizing an increase in processing load on the main control board 310. it can.

  Further, according to the pachinko gaming machine 100 described above, the main control board 310 calculates the command value and the random number value even when the number of individual identification values to be extracted and the extraction pattern are different, and calculates the individual identification value from the calculation result. Since it is only necessary to execute a common process of extraction, the process of the main control board 310 can be simplified as compared with the case where the number of individual identification values to be extracted and the process for each extraction pattern are performed.

  Further, the pachinko gaming machine 100 described above identifies, for each of a plurality of types of control command information 1010, a command value for identifying the control command information 1010 and specifying one individual identification value by calculation with a random value. Therefore, the main control board 310 only needs to calculate the command value and the random number value, and the processing of the main control board 310 can be simplified, so that the data amount of the program can be reduced.

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

  As described above, the present invention is useful for an electronic device in which fraud to the main control unit is a concern and a gaming machine on which the electronic device is mounted, and in particular, a pachinko gaming machine, a slot gaming machine, and a sparrow ball gaming machine. It can be applied to various other gaming machines. Even in these gaming machines, the same effects as those of the above-described embodiments can be obtained by configuring similarly to the above-described embodiments.
