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.

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

  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.

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

A transfer step of transferring to the subsequent stage, a peripheral side receiving step of receiving the subsequent authentication result data from the subsequent stage, and the predetermined processing based on the control command information according to the received subsequent authentication result data And a processing step to be performed.

  According to the first and third aspects of the present invention, the main control unit has three or more types based on predetermined storage data, for example, at a predetermined timing such as at the time of start-up and at the time of resetting. When the individual identification values are generated in a predetermined order, the first individual identification value is determined from the three or more types of individual identification values, and the predetermined individual identification value is determined from the determined first individual identification value. As shown, three or more types of individual identification values are stored in the individual identification value storage means. 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 in which the extracted individual identification value in the storage order is added to the history data by a predetermined addition method, and can transmit the authentication information to the peripheral unit. On the other hand, the peripheral unit transfers each of the authentication information and the control command received from the main control unit to the subsequent unit. On the other hand, the expected value storage means in the subsequent stage stores in advance three or more types of expected values that match each of the three or more types of individual identification values to be generated by the main control unit. Then, when receiving the control command information from the main control unit via the peripheral unit, the subsequent unit generates subsequent-stage history data indicating the history of the received control command information 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 latter stage unit specifies the storage order to be extracted from the storage order of the three or more types of individual identification values. The subsequent stage extracts each of the three or more types of expected values stored in the expected value storage means 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 latter-stage 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 subsequent stage specifies 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 authentication information received from the main control unit by the additional method. Then, the post-stage unit generates post-stage authentication result data indicating the authentication result of the main control unit determined based on whether or not the extracted authentication history data matches the post-stage history data, and transmits it to the peripheral unit can do. On the other hand, the peripheral unit can perform a predetermined process in the electronic device based on the control command information received from the main control unit according to the subsequent authentication result data received from the subsequent unit.

  According to the second aspect of the present invention, the main control board has three or more types of individual identification based on predetermined storage data at predetermined timings such as at the time of start-up and at the time of reset. When the values are generated in a predetermined order, the head individual identification value is determined from the three or more types of individual identification values, and the order of the predetermined order is determined from the determined head individual identification values. As described above, three or more types of individual identification values are stored in the individual identification value storage means. When the main control board transmits control command information to the peripheral portion of 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 unit can generate authentication information in which the extracted individual identification value in the storage order is added to the history data by a predetermined addition method, and can transmit the authentication information to the peripheral unit. On the other hand, the peripheral part of the peripheral board transfers each of the authentication information and the control command received from the main control part to the subsequent stage part. On the other hand, the expected value storage means at the rear stage of the peripheral board stores in advance three or more types of expected values that match each of the three or more types of individual identification values to be generated by the main control board. Then, when receiving the control command information from the main control unit via the peripheral unit, the subsequent unit generates subsequent-stage history data indicating the history of the received control command information by the same history generation method as that of the main control board. . Based on the command value of the control command information received from the main control board, the subsequent stage specifies the storage order to be extracted from the storage order of the three or more types of individual identification values. The latter stage extracts each of the three or more types 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, and extracts three or more types of authentication history data. Then, the individual identification in the main control board is performed based on the individual identification value corresponding to the authentication history data that matches the subsequent history data among the extracted three or more types of authentication history data and the specified storage order. The storage order of values can be determined. Then, after the storage order of the individual identification values is determined, the subsequent stage specifies the storage order based on the command value of the control command information received from the main control board, and matches the individual identification value corresponding to the storage order. The authentication history data is extracted by removing the expected value from the authentication information received from the main control board by the additional method. Then, the post-stage unit generates post-stage authentication result data indicating the authentication result of the main control board determined based on whether or not the extracted authentication history data matches the post-stage history data, and transmits it to the peripheral unit can do. On the other hand, the peripheral part of the peripheral board can perform a predetermined process in the electronic device based on the control command information received from the main control part according to the post-authentication result data received from the post-stage part.

  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. In addition, the main control unit generates, for example, three or more types of individual identification values in a predetermined order based on predetermined storage data at predetermined timings such as at start-up and resetting. Then, the first individual identification value is determined from the three or more types of individual identification values, and the three or more types of individual identification values are individually identified from the determined first individual identification values in a predetermined order. Store in the value storage means. 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 in which the extracted individual identification value in the storage order is added to the history data by a predetermined addition method, and can transmit the authentication information to the peripheral unit. On the other hand, the peripheral unit transfers each of the authentication information and the control command received from the main control unit to the subsequent unit. On the other hand, the expected value storage means in the subsequent stage stores in advance three or more types of expected values that match each of the three or more types of individual identification values to be generated by the main control unit. Then, when receiving the control command information from the main control unit via the peripheral unit, the subsequent unit generates subsequent-stage history data indicating the history of the received control command information 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 latter stage unit specifies the storage order to be extracted from the storage order of the three or more types of individual identification values. The subsequent stage extracts each of the three or more types of expected values stored in the expected value storage means 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 latter-stage 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 subsequent stage specifies 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 authentication information received from the main control unit by the additional method. Then, the post-stage unit generates post-stage authentication result data indicating the authentication result of the main control unit determined based on whether or not the extracted authentication history data matches the post-stage history data, and transmits it to the peripheral unit can do. On the other hand, the peripheral unit can perform a predetermined process in the electronic device based on the control command information received from the main control unit according to the subsequent authentication result data received from the subsequent unit.

  As described above, according to the present invention, 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 latter part via the peripheral part, even if the latter part uses the history data of the authentication information for authentication of the main control part, the individual added to the history data Since the identification value changes irregularly depending on the random number value, 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 main control unit generates three or more types of individual identification values in the order of arrangement based on the stored data of the main control unit, three or more types of individual identification values are stored in the main control unit in advance. Therefore, an increase in the amount of data stored in advance for authentication of the main control unit can be suppressed. Since the main control unit can store three or more types of individual identification values in advance by the time of generating the authentication information, it is not necessary to perform a complicated operation when generating the authentication information. Increase in burden can be prevented. 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 latter part determines the storage order of the three or more types of individual identification values in the main control part from the storage order specified based on the control command information and the authentication history data extracted from the authentication information. If the latter part stores only the arrangement order of three or more types of individual identification values, the storage order changed by the main control unit can be detected and determined, so that three or more types of individual identification values and Unauthorized analysis of authentication information can be made difficult. Moreover, the latter part extracts the authentication history data from the authentication information using only the expected value corresponding to the command value of the control command information for the three or more kinds of expected values, and the extracted authentication history data and the latter part 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 subsequent 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. Further, since the latter part is configured to confirm and authenticate communication continuity of the control command information based on the history data, it is possible to detect unauthorized communication switching due to unauthorized control command information. It can contribute to prevention of communication switching. Moreover, since the latter part extracts the history data for authentication using one or a plurality of expected values from the authentication information, if the regular individual identification value is not added to the history data, the authentication history data and the latter side 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 subsequent stage 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. Furthermore, since the latter part performs authentication processing for the main control unit and transmits the subsequent authentication result to the peripheral part, the peripheral part only needs to refer to the latter authentication result without performing the authentication process. The processing load on the peripheral CPU can be reduced. In addition, since the latter part manages the history of control command information from the main control part, the history of control command information is not required in the peripheral part, so the processing burden on the peripheral part is increased by improving security. Can be prevented. In addition, since the peripheral unit can transfer the control command information received from the main control unit to the subsequent stage unit and perform predetermined processing, the peripheral unit and the subsequent stage unit can perform processing simultaneously. It is possible to prevent a delay from occurring in the predetermined processing. Therefore, it is possible to check the communication continuity of the control command information by using the existing configuration and minimizing the increase in processing load of the main control unit, making it difficult to analyze the authentication information used for authentication, and The processing load on the peripheral CPU can be reduced.

  The configuration of the board of the pachinko gaming machine 100 is not limited to this. For example, the prize ball control unit 203 is provided on the same printed circuit board as the main control unit 201 or the production control unit 202A and the rear stage unit 202B. Different configurations can be used. In addition, the production control unit 202A and the rear stage unit 202B are configured so that one printed circuit board is mounted on the other printed circuit board instead of the structure realized by the same printed circuit board, and a separate printed circuit board is electrically connected by a cable or the like. Various embodiments such as a configuration to be connected can be used.

(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, an individual identification value generation unit 312, a determination unit 313, a history data generation unit 314, and a calculation unit 315. , An extraction unit 316, an authentication information generation unit 317, and a main control side transmission unit 318. 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 portion 202A of the peripheral board 330 is possible.

  The data storage unit 311 corresponds to the individual identification value storage unit of the present invention, and includes control command information (control command), authentication information, individual identification value, history generation method data (history generation method), additional information transmitted to the peripheral unit 202A. Various data such as method data are stored. As the data storage unit 311, for example, a part of the ROM 212 and the RAM 213 (see FIG. 2) of the main control unit 201 can be used.

  The data storage unit 311 has a storage area for storing a plurality of types of control command information and a plurality of authentication information transmitted to the peripheral unit 202A 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 set arbitrarily timings, such as after transmitting to the peripheral part 202A, 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 generated by the individual identification value generation unit 312 described later and arranged in a predetermined order from the first individual identification value determined by the determination unit 313. Each of the three or more types of individual identification values is a value used by the rear stage part 202B of the peripheral board 330 for authentication (individual value identification) of the main control board 310 (main control part), and will be described later. Is added to the history data.

  The history generation method data indicates a history generation method used by the history data generation unit 314, and is determined in advance with the rear stage unit 202B of the peripheral board 330, and an initial value is set at the time of startup or the like to store data. Stored in the unit 311.

  The individual identification value generation unit 312 corresponds to the individual identification value generation unit of the present invention, and three or more types of individual identification values arranged in a predetermined order for identifying the main control board 310 are used as the main control board 310. Are generated based on predetermined storage data. Note that three or more types of individual identification values arranged in a predetermined order are stored in the ROM 212 or the like, and the relationship is a ring. The predetermined order is an order in which three or more types of individual identification values are arranged, and examples include ascending order, descending order, and irregular order. Then, the individual identification value generation unit 312 generates an individual identification value in accordance with the storage data and a predetermined individual identification value generation method, so that an expected value that matches the individual identification value to be generated by the main control board 310 is set. If stored in the peripheral board 330, the rear stage 202B of the peripheral board 330 is illegal in the stored data of the main control board 310 based on whether or not the individual identification value matches the expected value. And the individual identification of the main control board 310 can be authenticated.

  The stored data is unique data of the main control unit 310 stored in advance in the ROM 212 of the main control unit 201. Examples of stored data include program data executed by the CPU 211 of the main control unit 310, fixed data dedicated for authentication, etc., in which case the data is determined by the time of manufacturing the pachinko gaming machine 100, etc. Will do. Since the stored data is stored in the data storage unit 311, ROM 212, etc., the data storage unit 311, ROM 212, etc. store the stored data as stored data storage means. Also, the jackpot related program data (a part of the program data stored in the ROM 212) for the main control board 310 to control the jackpot in the pachinko gaming machine 100 may be illegally rewritten. By using stored data having program data, the individual identification value generated by the individual identification value generation unit 312 and the expected value of the rear stage unit 202B do not coincide with each other due to the occurrence of data falsification. Can be detected and can contribute to prevention of tampering.

  The individual identification value generation unit 312 generates an individual identification value at a predetermined generation timing. As an example of the generation timing, when the pachinko gaming machine 100 is activated, when a predetermined control command information is generated or when a predetermined number of occurrences is detected, a predetermined time or after the pachinko gaming machine 100 is activated For example, every time the main control board 310 is authenticated when a predetermined time has elapsed. Note that each time the main control board 310 is authenticated means a timing for generating authentication information to be described later or a timing for transmitting to the peripheral board 330.

  As an example of an individual identification value generation method of the individual identification value generation unit 312, a checksum of stored data in different predetermined areas (ranges) in the ROM 212, a total value of odd or even addresses in each predetermined area, For example, stored values extracted from a plurality of different predetermined addresses may be used. Note that the generation timing and the individual identification value generation method of the individual identification value generation unit 312 can be set differently for each type of pachinko gaming machine 100, each specification, and the like. The individual identification value generation method of the individual identification value generation unit 312 is a generation method different from the history generation method of the history data generation unit 313 described later so that the individual identification value and the history data do not match. In addition, the design can be performed in consideration of, for example, different bit assignments, generation ranges, and the like.

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

  The determination unit 313 corresponds to a determination unit of the present invention, and the first of three or more types of individual identification values generated by the individual identification value generation unit 312 and arranged in a predetermined order is determined at a predetermined timing. Individual identification values are randomly determined. The determination unit 313 randomly determines one leading individual identification value from among three or more types using, for example, random numbers.

  The determination unit 313 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 313 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 generation timing generated by the individual identification value generation unit 312 and the determination timing determined by the determination unit 313 may be the same timing or different timings. As the same timing, for example, both the generation timing and the determination timing are when the pachinko gaming machine 100 is started, when it is reset, and the like. Further, as different timings, for example, the generation timing is set to the pachinko gaming machine 100, and the determination timing is set to an arbitrary timing thereafter.

  The history data generation unit 314 corresponds to the history data generation unit of the present invention, and generates history data indicating a history of control command information transmitted from the main control board 310 to the peripheral part 202A of the peripheral board 330. Generate by method. The history data generation unit 314, for example, at a predetermined generation timing such as an arbitrary timing from the generation (determination) of control command information to the peripheral unit 202A of the control command information in the pachinko gaming machine 100, Based on the history generation method and the control command information stored in the data storage unit 311, history data is generated and stored. Then, the history data generation unit 314 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, etc. 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 314 generates the history data as a checksum, the total value of the single type of control command information and the history data are the total value obtained by summing up the 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 314 according to the present embodiment will be described in the 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 314 generates the same history data as the individual identification value, for example, the authentication information generation unit 317 does not generate authentication information having the history data, or the main control side transmission The configuration is such that the unit 318 discards the authentication information having the history data without transmitting it. Alternatively, the history data generation unit 314 may be designed to generate history data having a value different from the individual identification value, or may be various embodiments such as corresponding to the bit adjustment of the history data.

  The calculation unit 315 corresponds to the calculation means of the present invention, calculates different command values and random numbers included in each of a plurality of types of control command information using 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 selected from among 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 in this embodiment is mask data that masks other than the desired bits of 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 315 is associated with one of three or more types of individual identification values on a one-to-one basis.

  For example, when the operation method is a logical product (AND) operation, the operation unit 315 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 an operation 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. The calculation unit 315 of the present embodiment will be described with respect to the case where it is realized by software, but instead, the same processing may be realized by hardware such as logic times.

  The extraction unit 316 corresponds to the extraction unit of the present invention, and the calculation result of the calculation unit 315 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 results of the calculation unit 315 and the storage order are associated one-to-one. With such a configuration, the extraction unit 316 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 addition, although a present Example demonstrates the structure which separates the calculating part 315 and the extraction part 316, it replaces with this and may be set as embodiment which comprises the calculating part 315 and the extraction part 316 integrally. it can.

  The authentication information generation unit 317 corresponds to the authentication information generation unit of the present invention, and generates authentication information used by the subsequent stage unit 202B for authentication of the main control unit 201. The authentication information generation unit 317 generates authentication information by adding the individual identification value in the storage order extracted by the extraction unit 316 to the latest history data stored in the data storage unit 311 by a predetermined addition method. . That is, the authentication information generation unit 317 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 rear stage portion 202B of 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, etc., and the rear stage 202B of the main control board 310 and the peripheral board 330 is Additional method data indicating the calculation method is stored in the data storage unit 311 or the like. 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 main control side transmission unit 318 corresponds to the main control side transmission unit of the present invention, transmits each of the authentication information and the control command information generated by the authentication information generation unit 317 to the peripheral unit 202A of the peripheral board 330, and Then, the data is transmitted to the rear stage part 202B via the peripheral part 202A. Then, the main control side transmission unit 318 of this embodiment transmits control command information from the main control board 310 to the peripheral part 202A of the peripheral board 330 as a control signal. The main control side transmitting unit 318 transmits authentication information to the peripheral unit 202A as an authentication information signal that is a signal different from the control signal transmitted from the main control board 310 to the peripheral unit 202A, for example. 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 a function as a peripheral part such as the above-described effect control unit 202A will be described. As shown in FIG. 3, the peripheral board 330 includes a peripheral part (effect control part) 202 </ b> A and a rear stage part 202 </ b> B. And the peripheral board | substrate 330 is comprised so that bidirectional | two-way communication is possible between the peripheral part (effect control part) 202A and the back | latter stage part 202B. In this embodiment, the peripheral board 330 having the production control unit 202A and the rear stage part 202B will be described, but instead, a peripheral board provided with the rear stage part 202B on the prize ball control unit 203 side. You can also

  First, the post-stage unit 202B includes a post-stage reception unit 331, a post-stage storage unit 332, a post-stage history data generation unit 333, a specification unit 334, a first extraction unit 335, a storage order determination unit 336, a second extraction unit 337, a post-stage An authentication result data generation unit 338 and a rear-stage transmission unit 339 are included.

  The post-stage receiving unit 331 corresponds to the post-stage receiving unit of the present invention, and receives the control command information and authentication information transmitted from the peripheral unit 202A by the main control board 310 and transferred from the peripheral unit 202A. That is, the rear receiving unit 331 receives various information from the main control board 310 via the peripheral unit 202A. The rear-stage receiving unit 331 of the present embodiment receives the authentication information from the main control board 310 via the peripheral unit 202A, for example, by receiving an authentication information signal corresponding to the authentication information. Further, the rear receiving unit 331 receives the control command information by receiving the control signal transferred from the peripheral unit 202A separately from the authentication information signal. The subsequent-stage receiving unit 331 stores the received control command information and control command information in the subsequent-stage storage unit 332 in time series.

  The rear stage storage unit 332 corresponds to the expected value storage unit of the present invention. As the rear-stage storage unit 332, for example, a part of the ROM 22 and the RAM 23 (see FIG. 2) of the rear-stage unit 202B can be used. Further, the rear-stage storage unit 332 stores a plurality of control command information and a plurality of authentication information received from the main control board 310 via the peripheral unit 202A in a time series as log data, like the main control board 310. Storage area.

  The rear-stage storage unit 332 has three or more types of individual identification values to be received from the main control board 310 via the peripheral unit 202A, that is, three or more types of individual identification values generation unit 312 of the main control board 310 should generate. Three or more types of expected values that match each individual identification value are stored. As a result, the rear stage 202B of the peripheral substrate 330 matches any one of three or more expected values if the individual identification value added to the authentication data history data is a normal individual identification value. The post-stage unit 202B can extract history data from the authentication information. Further, if the individual identification value of the authentication information is invalid, it does not match any of the three or more expected values, so that the historical data 202B cannot be extracted from the authentication information.

  The expected value is obtained in advance by three or more types of individual identification values to be generated by the individual identification value generation unit 312 of the main control board 310 by calculation using the storage data of the main control board 310 and the history generation method. It is stored (written) in advance in the rear storage unit 332 when the machine 100 is manufactured. When the rear-stage storage unit 332 is the RAM 243, three or more types of expected values are stored in the ROM 232, and stored in the rear-stage storage unit 332 from the ROM 232 when the pachinko gaming machine 100 is activated.

  The post-stage 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 subsequent-stage history data generation unit 333, and an initial value is set at the time of startup or the like and is stored in the subsequent-stage storage unit 332. The additional method data indicates the same additional method as that of the main control board 310 used by the second extraction unit 337.

  The rear 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 subsequent storage unit 332.

  The latter-stage history data generation unit 333 corresponds to the latter-stage history data generation means of the present invention, and the latter-stage history data indicating the history of control command information received from the main control board 310 is the same as the main control board 310 described above. Generate by history generation method. The post-stage history data generation unit 333 receives the same history generation method and post-stage side as the main control board 310 at a predetermined post-stage generation timing such as when receiving control command information from the main control board 310, after receiving the control command information. Based on the control command information stored in the storage unit 332, post-stage history data is generated and stored. In other words, the latter-stage 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 only the control command information transmitted from the main control board 310 is received, the subsequent-stage history data matches the history data of the main control board 310. If not, an illegal control command is obtained. It can be determined that information is received.

  Note that the latter-stage history data generation unit 333 of the present embodiment will be described with respect to the case where the latter-stage history data stored in the latter-stage storage unit 332 is updated and stored in the generated latter-stage history data. In this case, the post-stage storage unit 332 functions as post-stage history data storage means. Instead of this, for example, the post-stage history data may be stored in a register of the CPU 21, a predetermined storage area of the RAM 23, or the like. Further, the post-stage history data generation means and the 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 has three or more types of individual identification values based on the command value of the control command information received from the main control board 310 by the rear receiving unit 331. The storage order to be extracted is specified from the storage order. 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 a first extraction unit of the present invention, and authentication information received by the subsequent-stage receiving unit 331 for each of three or more types of expected values using the same additional method as the main control board 310. The authentication history data of three or more types is extracted and stored in the subsequent storage unit 332. That is, when there are four expected values, the first extraction unit 335 extracts four pieces of authentication history data. Therefore, 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 latter-stage 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, and after the storage order is determined, the main control by the subsequent authentication result data generation unit 338. The substrate 310 can be authenticated. Thereby, the determination part 313 of the main control board 310 can rotate in accordance with the arrangement order of three or more kinds 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 rear receiving unit 331 by the same additional 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 subsequent-stage 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 each of one or a plurality of expected values from the authentication information (authentication data), and therefore extracted from the authentication information if received. One of the one or more authentication history data is the 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 post-authentication result data generation unit 338 corresponds to post-authentication result data generation means of the present invention, and is stored in the post-stage storage unit 332 in 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 whether or not there is a match with the latest post-stage history data, and the post-authentication result data indicating the authentication result is generated. And transmitted to the peripheral portion 202A. Then, if there is a match with the post-stage history data, the post-authentication result data generation unit 338 can determine that the history data of the received authentication information is valid, and thus establish authentication. Further, when there is no data that matches the post-stage history data, the post-stage authentication result data generation unit 338 uses, for example, invalid authentication information in which the history data and the post-stage history data are different due to fraud. Therefore, since the history data or individual identification value of the received authentication information can be determined to be invalid, authentication is not established. That is, the latter-stage authentication result data indicates an authentication result indicating whether or not the latter-stage unit 202B has authenticated the main control board 310 (the main control unit 201) based on communication continuity (history data).

  In this embodiment, after the authentication history data extraction unit 335 extracts a plurality of authentication history data, the second extraction unit 337 compares each of the plurality of authentication history data with the subsequent history data. However, instead of this, for example, each time the authentication history data extraction unit 335 extracts one authentication history data, the subsequent authentication result data generation unit 338 compares with the subsequent history data. You can also.

  The post-stage transmission unit 339 corresponds to the post-stage transmission unit of the present invention, and transmits the post-stage authentication result data generated by the post-stage authentication result data generation unit 338 to the peripheral unit 202A. Then, the post-stage transmission unit 339 transmits the generated post-stage authentication result data to the peripheral unit 202A as a post-stage authentication result signal, for example.

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

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

  The peripheral side receiving unit 352 corresponds to the peripheral side receiving means of the present invention, and receives the post-stage authentication result data and the like transmitted by the post-stage part 202B of the peripheral board 330. Then, the peripheral side receiving unit 352 of the present embodiment receives the post-stage authentication result data from the post-stage unit 202B, for example, by receiving the post-stage authentication result signal transmitted by the post-stage unit 202B.

  The processing unit 353 corresponds to the processing means of the present invention, and performs predetermined processing in the pachinko gaming machine 100 according to the subsequent authentication result data received from the subsequent unit 202B. The processing unit 353 extracts control command information from the control signal received from the main control board 310 and performs a predetermined process corresponding to the control command information when the post-authentication result data indicates that authentication is established. Moreover, the process part 353 alert | reports, when the said back | latter authentication result data has shown authentication failure. The predetermined processing is performed in accordance with control command information from the main control unit 201 in the pachinko gaming machine 100, such as, for example, discontinuation processing, jackpot reach processing, jackpot start processing, jackpot round processing, jackpot end processing, etc. Processing.

  In the present embodiment, data that is communicated between the peripheral unit 202A and the subsequent unit 202B is not encrypted. However, data that is communicated between the peripheral unit 202A and the subsequent unit 202B is also encrypted. It can also be configured.

  In this embodiment, the CPU 211 of the main control board 310 is the first computer, the CPU 241 of the peripheral part (production control part) 202A of the peripheral board 330 is the second computer, and the CPU 21 of the rear stage part 202B of the peripheral board 330 is the third computer. Will be described. The ROM 212 of the main control board 310 includes an individual identification value generation unit, a determination unit, a history data generation unit, a calculation unit, an extraction unit, an authentication information generation unit, a main control side transmission unit, and the first computer. The main control side authentication program for functioning as various means such as is stored. The ROM 242 of the peripheral portion 202A of the peripheral board 330 stores a peripheral side authentication program for causing the second computer to function as various means such as transfer means, peripheral side receiving means, and processing means. Yes. Further, the ROM 22 of the rear stage portion 202B of the peripheral board 330 includes the third computer in the rear side receiving means, the rear stage history data generating means, the specifying means, the first extracting means, the storage order determining means, and the second extraction. The post-stage authentication program for functioning as various means such as means, post-stage authentication result data generation means, and post-stage transmission means is stored. That is, the authentication program of the present invention is constituted by the main control side authentication program, the peripheral side authentication program, and the subsequent stage side authentication program.

(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 202A every time a game ball wins the start winning opening 105, and the effect control unit 202A displays the symbols on the symbol display unit 104 in a variable manner. Repeat and stop. The main control unit 201 outputs the corresponding control command information to the effect control unit 202A when the occurrence of the jackpot is determined, and the effect control unit 202A aligns with a predetermined design and stops the variable display. Then, control for opening the special winning opening 109 is performed. The effect control unit 202A displays various effects in addition to the symbol variation display on the symbol display unit 104 during the jackpot occurrence period and during the reach until the jackpot occurrence or at the time of the reach notice. . In addition, effects such as 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, the control process of the effect control unit 202A by the main control unit 201 will be described. 4 to 9, the authentication data and the accompanying data are not considered in order to clarify the control processing procedure of the effect control unit 202A. That is, in the description of FIGS. 4 to 9, “send a command” means “send a control signal including data (control command 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 202A and the prize ball control unit 203, and the process proceeds to step S403. When the power-on command is transmitted by this process, the effect control unit 202A controls the lamp control unit 251, the sound control unit 252, and the symbol display unit 104 for control command information for the effect at the time of power-on (specifically, Control command for instructing lamp lighting, sound output, demonstration 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 410. On the other hand, if the main control unit 201 determines that the number of undrawn winning prizes is zero (S403: Yes), in step S404, the main control unit 201 measures the time elapsed since the demonstration was started, and proceeds to the process of step S405. To do.

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

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

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

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

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

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

  The various commands in FIGS. 4 and 5 described above correspond to the control 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 the authentication information is generated, so that the processing load on the main control board 310 can be reduced. Further, every time the rear stage unit 202B of the peripheral board 330 receives various control command information, the control unit stores the control command information in the rear stage storage unit 332 as history, and the rear stage history data of the rear stage storage unit 332 is stored. Update at any time.

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

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

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

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

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

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

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

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

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

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

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

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

(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 this embodiment, it is assumed that the main control unit 201 transmits an authentication information signal from the main control unit 201 to the rear stage unit 202B by outputting an authentication information signal to the rear stage unit 202B via the peripheral unit 202A. To do.

  In FIG. 11, authentication information 1020 includes an identification unit 1021 and a data unit 1022. The identification unit 1021 is set with identification data that can identify the authentication information 1020. An example of the identification data is one type of authentication command. For example, hexadecimal values such as 0xA0 and 0xB0 are set. As a result, the post-stage unit 202B can identify the authentication information 1020 based on the identification unit 1021. The authentication command can be differentiated from the command value 1001 by using a command different from the control command having 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.

  Subsequently, the subsequent authentication result signal illustrated in FIG. 11 transmits, to the peripheral unit 202A, the subsequent authentication result information 1030 indicating the authentication result of the authentication performed by the main control unit 201 using the authentication information 1020 described above. . The latter authentication result information 1030 includes an identification unit 1031 and a result unit 1032. In the identification unit 1031, identification data that can identify the subsequent authentication result information 1030 is set. As the identification data, various embodiments such as diverting data set in the identification unit 1021 of the authentication information 1020 or using predetermined data can be used. The result unit 1032 is set with authentication result data indicating whether or not the post-stage unit 202B has authenticated the main control board 310. Note that when the result unit 1032 indicates that authentication is not established, the result unit 1032 includes detailed data indicating that the authentication data is not established due to a mismatch in history data, for example.

(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, 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 two 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, the method of adding history data to the individual identification value described above defines a method of adding the individual identification value to the history data. For example, one arithmetic method among four arithmetic operations, XOR, XNOR, etc. It is predetermined 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 sets the authentication information 1020. Is generated. On the other hand, the rear stage part 202B of the peripheral board 330 subtracts one or more expected values specified as described above from the data set in the data part 1022 of the received authentication information 1020, thereby obtaining one or more authentication histories. Extract data. Since the three or more types of expected values coincide with each of the three or more types of individual identification values, one or a plurality of pieces of authentication data extracted by removing the expected value by the rear stage portion 202B of the peripheral board 330 are extracted. Since one piece of regular history data has been extracted, it should match the latter-stage history data.

  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 sets the authentication information 1020. Is generated. On the other hand, the rear stage part 202B of the peripheral board 330 adds one or more expected values specified as described above from the data set in the data part 1022 of the received authentication information 1020, to thereby obtain one or more authentication histories. Extract data. 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 rear stage part 202B of the peripheral board 330 adds the expected values, the extracted 1 or Since one regular history data can be extracted from a plurality of authentication data, it should match the latter history data.

  Therefore, any calculation method may be used as long as the additional method is a calculation method in which the rear stage 202B of the peripheral substrate 330 can perform reverse calculation. In the present embodiment, a case will be described in which the main control board 310 adds only the individual identification value to the history data. Instead, it is determined in advance between the individual identification value and the rear stage portion 202B of the peripheral board 330. Various embodiments such as adding both of the added data (for example, a predetermined value) can be used.

(Processing for sending and receiving authentication information signals)
Hereinafter, an example of communication of the authentication information signal performed between the main control unit 201 and the subsequent stage unit 202B will be described. First, an example of an authentication information signal transmission procedure by the CPU 211 (first computer) of the main control unit 201 will be described with reference to 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 pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes the authenticated-side process shown in FIG. 16, and in step S1200, as described in the individual identification value generation unit 312, Based on the stored data and the individual identification value generation method, three or more types of individual identification values are generated according to the order, stored in the data storage unit 311, and then the process proceeds to step S <b> 1201. With this process, three or more types of individual identification values arranged in a predetermined order are generated.

  In step S1201, for example, the main control unit 201 determines whether or not it is a decision timing (timing) such as when the pachinko gaming machine 100 is started, when it is reset, or when a predetermined date and time is reached. 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, when the main control unit 201 determines that the generation of the control command information 1010 has been detected (S1204: Yes), the history generation method data in the data storage unit 311 and the history generation method are generated in step S1205. Based on the 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 S1206. 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 subsequent stage unit 202B, and in step S1211, at the predetermined transmission timing, An authentication information signal is generated based on the encrypted authentication information 1020 and transmitted from the main control side transmission unit 318 to the peripheral unit 202A, and then the process proceeds to step S1212. If encryption is not required between the main control unit 201 and the subsequent stage unit 202B, the processing in step S1210 is deleted and the authentication information 1020 is transmitted to the subsequent stage unit 202B 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.

  Subsequently, the procedure of the reception process of the authentication information signal by the CPU 21 (third computer) of the rear stage unit 202B will be described with reference to the flowcharts of FIGS.

  First, when the post-stage unit 202b executes the storage order determination process shown in FIG. 17 in response to, for example, activation or resetting of the pachinko gaming machine 100, the main control unit is referred to the post-stage storage unit 332 in step S1301. The control command information 1010 received from 201 is acquired, and then the process proceeds to step S1302. In step S1302, the rear stage unit 202B determines, based on the command value 1001 of the control command information 1010, one or more individual identification values that the main control unit 201 extracts from three or more types of individual identification values. The storage order is specified, the specified result is stored in the post-stage storage unit 332, etc., and then the process proceeds to step S1303.

  The post-stage unit 202B determines whether or not authentication information (authentication information signal) 1020 has been received from the main control unit 201 by the post-stage receiving unit 331 in step S1303. If it is determined that the authentication information 1020 has not been received (S1303: No), the latter stage unit 202B repeats this determination process to wait for reception of the authentication information 1020. On the other hand, when determining that the authentication information 1020 has been received (S1303: Yes), the subsequent stage unit 202B proceeds to the process of step S1304.

  In step S1304, the succeeding unit 202B decrypts the received authentication information 1020 with a decryption method corresponding to the encryption method of the main control unit 201, and extracts authentication data from the data unit 1022 of the authentication information 1020. One or a plurality of authentication history data obtained by removing one or a plurality of expected values matching 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 It memorize | stores in the memory | storage part 332, and it progresses to the process of step S1305 after that. If encryption is not required between the main control unit 201 and the subsequent unit 202B, the decryption process in step S1304 is deleted.

  In step S1305, the subsequent stage unit 202A determines that the individual identification value corresponding to the authentication history data that matches the subsequent history data among the extracted one or more authentication history data and the specified storage order. Based on this, 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 subsequent storage unit 332 etc. 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 subsequent stage unit 202B determines whether or not the storage order is determined based on the determination flag. Then, if it is determined that the storage order is not fixed (S1306: No), the rear stage unit 202B returns to the process of step S1303 and waits for the 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, if the latter stage unit 202B determines that the storage order is fixed (S1306: Yes), the process proceeds to step S1307.

  In step S1307, the rear stage unit 202B 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 can authenticate the main control unit 201 with the authentication information 1020. Then, the process according to this flowchart is terminated.

  Subsequently, when the post-stage unit 202B executes the authentication-side process illustrated in FIG. 18, the post-stage reception unit 331 performs the main control unit based on the control command information 1010 stored in the post-stage storage unit 332 in step S1401. It is determined whether control command information 1010 is received from 201. If the rear stage unit 202B determines that the control command information 1010 has not been received (S1401: No), the process proceeds to step S1404.

  On the other hand, if the latter stage unit 202B determines that the control command information 1010 has been received (S1401: Yes), the history generation method data of the latter stage side storage unit 332 and the same as the main control unit 201 in step S1402 Based on the control command information 1010 to be generated by the history generation method, the latter-stage history data is generated and stored in the latter-stage storage unit 332, and then the process proceeds to step S1403. Then, in step S1403, the rear stage unit 202B determines, based on the command value 1001 of the control command information 1010, one or more individual identification values that the main control unit 201 extracts from three or more types of individual identification values. Are stored in the subsequent storage unit 332 and the process proceeds to step S1404.

  The post-stage unit 202B determines whether or not authentication information (authentication information signal) 1020 is received from the main control unit 201 by the post-stage reception unit 331 in step S1404. If the latter stage unit 202B determines that the authentication information 1020 has not been received (S1404: No), the process proceeds to step S1411. On the other hand, if the latter stage unit 202B determines that the authentication information 1020 has been received (S1404: Yes), the process proceeds to step S1405.

  In step S1405, the rear stage unit 202B decrypts the received authentication information 1020 with a decryption method corresponding to the encryption method of the main control unit 201, extracts the authentication data from the data unit 1022 of the authentication information 1020, and performs the subsequent stage. One or a plurality of authentication histories that are stored in the side storage unit 332 and one or a plurality of expected values that match the individual identification values in the storage order indicated by the identification result are removed from the authentication data based on the additional method data The data is stored in the subsequent-stage storage unit 332, and then the process proceeds to step S1406. If encryption is not required between the main control unit 201 and the subsequent unit 202B, the decryption process in step S1405 is deleted.

  In step S1406, the rear stage unit 202B compares the extracted one or more authentication history data with the latest rear stage history data stored in the rear stage storage unit 332 and performs authentication for matching with the rear stage history data. The determination result as to whether or not history data exists is stored in the subsequent-stage storage unit 332 and the like, and then the process proceeds to step S1407.

  If the post-stage unit 202B determines in step S1407 that the matching authentication history data exists (S1407: Yes), the history data matches the post-stage history data, and the continuity of communication is valid. In step S1408, the authentication of the main control unit 201 is established, post-authentication result data indicating the establishment of authentication based on the history is generated and stored in the RAM 23, and then the process proceeds to step S1410. On the other hand, if it is determined that the matching authentication history data does not exist (S1407: No), the subsequent stage unit 202B indicates that the continuity of communication is not valid or is invalid authentication information, so that step S1409 is performed. , Authentication for the main control unit 201 is not established, post-authentication result data indicating that the authentication is not established is generated and stored in the RAM 23 or the like, and then the process proceeds to step S1410.

  In step S1410, the post-stage unit 202B sets the generated post-stage authentication result data in the result unit 1032 to generate post-stage authentication result information 1030, and generates a post-stage authentication result signal to which the post-stage authentication result information 1030 is added. Transmission is performed from the rear transmission unit 339 to the peripheral unit 202A, and then the process proceeds to step S1411.

  The post-stage unit 202B determines whether or not the pachinko gaming machine 100 is powered off in step S1411. If the rear stage unit 202B determines that the power is not turned off (S1411: No), the process returns to step S1401 and repeats a series of processes. On the other hand, if it is determined that the power is turned off (S1411: Yes), the rear stage unit 202B ends the process according to this flowchart.

  In the present embodiment, a case has been described in which the subsequent stage unit 202B extracts a plurality of pieces of authentication history data and then collectively compares them with the subsequent stage history data. However, instead of this, one piece of authentication history data is stored. It can also be set as the Example compared with back | latter stage side historical data, whenever it extracts.

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

  In step S1501, the peripheral unit 202A determines whether a control signal (control command information 1010) has been received from the main control unit 201. If the peripheral unit 202A determines that the control signal has been received (S1501: Yes), the control signal is transferred (transmitted) from the transfer unit 351 to the subsequent stage unit 202B as it is in step S1502, and then the process proceeds to step S1503. In step S1503, the peripheral unit 202A performs predetermined processing based on the control command data 1001 and the accompanying data 1002 included in the received control signal, and then proceeds to processing in step S1508.

  On the other hand, when it is determined that the peripheral unit 202A has not received the control signal (S1501: No), in step S1504, the peripheral unit 202A determines whether the authentication information (authentication information signal) 1020 has been received from the main control unit 201. . When it is determined that the authentication information 1020 has been received (S1504: Yes), the peripheral unit 202A transfers (transmits) the authentication information 1020 as it is from the transfer unit 351 to the post-stage unit 202B in step S1505, and then performs the process of step S1508. Proceed to On the other hand, if the peripheral unit 202A determines that the authentication information 1020 has not been received (S1504: No), the process proceeds to step S1506.

  In step S1506, the peripheral unit 202A determines whether or not the subsequent authentication result signal has been received from the subsequent unit 202B based on whether or not the received signal has the identification unit 1031. If the peripheral unit 202A determines that the subsequent authentication result signal has not been received (S1506: No), the process proceeds to step S1508. On the other hand, if the peripheral unit 202A determines that the post-authentication result signal has been received (S1506: Yes), the process proceeds to step S1507.

  In step S1507, the peripheral unit 202A refers to the result part 1032 of the received subsequent authentication result signal, and determines whether or not the subsequent authentication result signal indicates that authentication has been established. If the peripheral unit 202A determines that the subsequent authentication result indicates that the authentication is successful (S1507: Yes), the peripheral unit 202A stores the authentication result in the RAM 243 or the like, and then proceeds to the process of step S1508.

  In step S1508, the peripheral unit 202A determines whether or not the pachinko gaming machine 100 is powered off. If it is determined that the power is not turned off (S1508: No), the peripheral unit 202A returns to the process of step S1501 and repeats a series of processes. On the other hand, when it is determined that the power source is turned off (S1508: Yes), the peripheral unit 202A ends the process according to this flowchart.

  On the other hand, if the peripheral unit 202A determines in step S1507 that the subsequent authentication result does not indicate that authentication is successful (S1507: No), in step S1509, for example, the peripheral unit 202A outputs a notification signal from the speaker 262 (see FIG. 2) or the like. Then, the process according to this flowchart is terminated. As for the processing of the peripheral portion 202A when the subsequent authentication result does not indicate that authentication is successful, that is, when authentication is not successful, the processing of the peripheral portion 202A is continued only by outputting a notification signal. Also good.

  The peripheral part 202A of the present embodiment has been described with respect to the case where the latter part 202B corresponds to the same process before and after determining the storage order of the three or more types of individual identification values. Before the storage order is determined, various embodiments may be adopted, such as handling with a dedicated process for transferring various information from the main control unit 201 to the subsequent stage unit 202B.

(Example of authentication process)
Next, in the pachinko gaming machine 100, when the latter part 202B of the main control board 310 and the peripheral board 330 uses the above four individual identification values UA, UB, UC, UD and expected values VA, VB, VC, VD. An example of authentication 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 rear stage portion 202B of the peripheral board 330 stores the four expected values VA, VB, VC, and VD of the main control board 310 in the rear stage storage section 332 in advance, and the addition method of the main control board 310 is “+ ”Is remembered. That is, the rear stage portion 202 </ b> B of 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. 20, the main control board 310, which is the person to be authenticated, generates the four individual identification values UA, UB, UC, UD according to the sequence in accordance with, for example, activation or reset of the pachinko gaming machine 100 And stored in the RAM 213 or the like (S1600). Thereafter, when the main control board 310 randomly determines the head as the individual identification value UA from among the generated four individual identification values UA, UB, UC, and UD (S1601), as shown in case 1 of FIG. In addition, the data is stored in the data storage unit 311 in order from the individual identification value UA in the order in which the four individual identification values UA, UB, UC, and UD are arranged (S1602).

  When the main control board 310 transmits the control command CA to the peripheral section 202A of the peripheral board 330, the main control board 310 stores the control command CA in the data storage section 311 (S1603). 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 (S1604). 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 (S1605). 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 (S1606).

  On the other hand, when the peripheral portion 202A of the peripheral substrate 330 receives the control command CA, the peripheral portion 202A transfers the control command CA to the subsequent portion 202B of the peripheral substrate 330 (S1641). Then, the peripheral unit 202A performs a predetermined process corresponding to the received control command CA (S1642). Note that when the determination of the storage order is realized by the initial processing, dedicated processing, or the like of the peripheral board 330, the processing of S1642 can be deleted.

  On the other hand, when receiving the control command CA, the rear stage unit 202B of the peripheral board 330 stores the control command CA in the rear stage storage unit 332 (S1671), and, similarly to the main control board 310, the received control command CA and Based on the history generation method, post-stage history data is generated and stored in the post-stage storage unit 332 (S1672). Since the command value 1001 of the control command CA is 0x00, the post-stage unit 202B specifies that the storage order of the extraction target of the main control board 310 is 0x00 (S1673).

  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 part 202A of the peripheral board 310 (S1607). ). On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 received from the main control board 310 to the rear stage part 202B of the peripheral board 330 (S1643).

  On the other hand, the rear stage portion 202B of 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 post-stage unit 202B matches the authentication history data C0-VA, it detects that the specified storage order of the individual identification value UA that matches the expected value VA is 0x00 (first), and stores it. It is determined that the order is the order of the individual identification values UA, UB, UC, UD (S1674).

  As shown in FIG. 14, 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 a control command CA to the peripheral portion 202A of 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 section 311 (S1608). 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 (S1609). Then, the main control board 310 calculates the logical product of the command value 1001 (0x00) of the control command CA and the random number value, and stores the calculation result of 0x00 in the RAM 213 or the like (S1610). 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 (S1611). .

  On the other hand, when the peripheral portion 202A of the peripheral substrate 330 receives the control command CA, the peripheral portion 202A transfers the control command CA to the subsequent portion 202B of the peripheral substrate 330 (S1644). Then, the peripheral unit 202A performs a predetermined process corresponding to the received control command CA (S1645). On the other hand, the post-stage unit 202B stores the control command CA received from the peripheral unit 202A in the post-stage storage unit 332 (S1675) and, based on the received control command CA and the history generation method, similarly to the main control board 310. Post-stage history data is generated and stored in the post-stage storage unit 332 (S1676). Since the command value 1001 of the control command CA is 0x00, the post-stage unit 202B specifies 0x00 in the storage order that can be extracted from the main control board 310, and specifies the individual identification value UA corresponding to the 0x00. (S1677).

  Thereafter, the main control board 310 generates authentication information 1020 having authentication data C1 obtained by adding (adding) the extracted individual identification value UA to the latest history data, and transmits it to the peripheral part 202A of the peripheral board 310 (S1612). ). On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 received from the main control board 310 to the rear stage part 202B of the peripheral board 330 (S1646). On the other hand, the post-stage unit 202B 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 or not the authentication history data C1-VA matches the latest succeeding-stage history data, authentication is performed based on the continuity of communication of the control command information 1010 with the main control board 310 (S1678). Then, the post-stage unit 202B generates post-stage authentication result data indicating the authentication result and transmits it to the peripheral part 202A of the peripheral board 330 (S1679). On the other hand, the peripheral unit 202A stores the received subsequent authentication result data in the RAM 243 or the like.

  In FIG. 21, when the main control board 310 transmits the next control command CD to the peripheral portion 202A of the peripheral board 330, the main control board 310 stores the control command CD in the data storage section 311 (S1613). 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 (S1614). 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. (S1615). 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 (S1616). .

  On the other hand, when the peripheral part 202A of the peripheral board 330 receives the control command CD, the peripheral part 330A transfers the control command CD to the rear stage part 202B of the peripheral board 330 (S1647). Then, if the latter authentication result data indicates normality, the peripheral unit 202A performs a predetermined process corresponding to the received control command CD (S1648). On the other hand, the post-stage unit 202B stores the control command CD received from the peripheral unit 202A in the post-stage storage unit 332 (S1680), and similarly to the main control board 310, the post-stage unit 202B is based on the received control command and history generation method. Side history data is generated and stored in the subsequent-stage storage unit 332 (S1681). Since the command value 1001 of the control command CD is 0x03, the post-stage unit 202B has the storage order that can be extracted from the main control board 310, and includes four individual identification values UA, UB, UC, and UD. All are specified that the main control board 310 can be extracted (S1682).

  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 part 202A of the peripheral board 310 (S1617). ). On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 received from the main control board 310 to the rear stage part 202B of the peripheral board 330 (S1649). On the other hand, the post-stage unit 202B 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 based on continuity of communication of the control command with the main control board 310 is performed based on whether the subsequent-stage history data matches (S1683). Then, the post-stage unit 202B generates post-stage authentication result data indicating the authentication result and transmits it to the peripheral part 202A of the peripheral board 330 (S1684). On the other hand, the peripheral unit 202A stores the received subsequent authentication result data in the RAM 243 or the like.

  When the main control board 310 transmits the next control command CB to the peripheral section 202A of the peripheral board 330, the main control board 310 stores the control command CB in the data storage section 311 (S1618). Then, the main control board 310 generates history data based on the transmitted control command CB and the history generation method, and stores it in the data storage unit 311 (S1619). 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. (S1620). 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 (S1621). .

  On the other hand, when the peripheral part 202A of the peripheral board 330 receives the control command CB, the peripheral part 330A transfers the control command CB to the rear stage part 202B of the peripheral board 330 (S1650). Then, if the latter authentication result data indicates normality, the peripheral unit 202A performs a predetermined process corresponding to the received control command (S1651). On the other hand, the post-stage unit 202B stores the control command CB received from the peripheral unit 202A in the post-stage storage unit 332 (S1585), and, based on the received control command CB and the history generation method, similarly to the main control board 310. Post-stage history data is generated and stored in the post-stage storage unit 332 (S1686). Since the command value 1001 of the control command CB is 0x01, the post-stage unit 202B has 0x00 and 0x01 in the storage order, and the storage order in which the main control board 310 can be extracted, and the individual identification corresponding to the 0x00 and 0x01 The values UA and UB are specified (S1687).

  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 part 202A of the peripheral board 310 (S1622). ). On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 received from the main control board 310 to the rear stage part 202B of the peripheral board 330 (S1652). On the other hand, the rear stage portion 202B of 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. ) The authentication history data C3-VA, C3-VB are extracted, and based on whether the authentication history data C3-VA, C3-VB match the latest succeeding-stage history data, the main control board 310 Authentication based on the continuity of communication of the control command is performed (S1688). The post-stage unit 202B generates post-stage authentication result data indicating the authentication result, and transmits the post-stage authentication result data to the peripheral part 202A of the peripheral board 330 (S1689). On the other hand, the peripheral unit 202A stores the received subsequent authentication result data in the RAM 243 or the like. 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 1001 of 1010 and the random number 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 obtained. Since the authentication information 1020 added to the history data is generated and transmitted to the rear stage section 202B of the peripheral board 330 via the peripheral section 202A, the rear stage section 202B transmits the history data of the authentication information 1020 to the main control board 310. Even if it is used for authentication, the individual identification value added to the history data changes irregularly depending on the random number value. It can be expected to prevent unauthorized analysis of 020. In addition, since the main control unit generates three or more types of individual identification values in the order of arrangement based on the stored data of the main control unit, three or more types of individual identification values are stored in the main control unit in advance. Therefore, an increase in the amount of data stored in advance for authentication of the main control unit can be suppressed. Since the main control unit can store three or more types of individual identification values in advance by the time of generating the authentication information, it is not necessary to perform a complicated operation when generating the authentication information. Increase in burden can be prevented. Moreover, since the storage order of the three or more types of individual identification values in the main control board 310 changes randomly, the individual identification values extracted based on the storage order change, so that the individual identification values added to the history data Can be changed in a more complicated manner, and it is possible to contribute to prevention of unauthorized analysis of the authentication information 1020. Further, the rear stage unit 202B 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 history data for authentication extracted from the authentication information 1020. Therefore, if the rear stage unit 202B stores only the arrangement order of three or more types of individual identification values, the main control board 310 can detect and determine the changed storage order, so that there are three types. Unauthorized analysis of the individual identification value and the authentication information 1020 can be made difficult. Moreover, the post-stage unit 202B 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 subsequent stage 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 rear stage 202B of 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 a plurality of types of command values, and fraud analysis with respect to the authentication information 1020 can be further performed. It can be difficult. Furthermore, since the rear stage part 202B of the peripheral board 330 confirms and authenticates the communication continuity of the control command information 1010 based on the history data, it detects an unauthorized communication switching due to the unauthorized control command information. Therefore, it is possible to contribute to prevention of unauthorized communication switching. In addition, since the post-stage unit 202B extracts the authentication history data from the authentication information 1020 using one or a plurality of expected values, when the regular individual identification value is not added to the history data, the authentication history data and Since the latter-stage 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 rear stage portion 202B of the peripheral board 330, the analysis load on the illegal board increases, so the processing capability must be increased. It is possible to increase the cost and the degree of design difficulty and contribute to the inhibition of the production of illegal substrates. Further, since the rear stage unit 202B performs the authentication process for the main control board 310 and transmits the subsequent stage authentication result to the peripheral unit 202A, the peripheral unit 202A simply refers to the subsequent stage authentication result without performing the authentication process. Therefore, the processing load on the CPU 241 in the peripheral portion 202A can be reduced. Further, since the rear stage unit 202B manages the history of the control command information 1010 from the main control board 310, the peripheral unit 202A does not need to manage the history of the control command information 1010. An increase in processing load on 202A can be prevented. In addition, since the peripheral unit 202A can transfer the control command information 1010 received from the main control board 310 to the rear stage unit 202B and perform a predetermined process, the peripheral unit 202A and the rear stage unit 202B can perform processing simultaneously. Therefore, it is possible to prevent the predetermined process in the peripheral portion 202B from being delayed. Therefore, it is possible to check the communication continuity of the control command information 1010 by using an existing configuration and minimizing an increase in the processing load of the main control board 310, making it difficult to analyze the authentication information 1020 used for authentication. And the processing load on the CPU 241 in the peripheral portion 202A can be reduced.

  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.
