Description

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

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

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

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

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

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

  Furthermore, 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.

A peripheral side receiving step of receiving a subsequent authentication result data, characterized in that it comprises a and a processing step of performing predetermined processing based on the control command in response to the subsequent authentication result the received data.

  According to the gaming machine authentication method of the present invention described in claim 7, when the main control unit transmits a control command to the peripheral unit according to the operation of the gaming machine, the history data indicating the history is generated as a history generation method. Generate with The main control unit generates authentication information having the history data as authentication data and transmits the authentication information to the subsequent stage unit via the peripheral unit. Further, when the main control unit randomly determines to switch the history generation method, the main control unit generates authentication information having the individual identification value stored in the individual identification value storage unit as the authentication data, and adds a peripheral part to the latter part. The history generation method of the history data generation means can be switched by a predetermined switching method from a plurality of predetermined history generation methods. On the other hand, the peripheral unit transfers the authentication information and the control command received from the main control unit to the subsequent unit. On the other hand, when receiving the control command from the main control unit, the subsequent stage unit generates the subsequent stage history data indicating the history of the received control command by the same history generation method as that of the main control unit. Then, the latter part includes the latter authentication result data indicating the authentication result of the main controller determined based on whether or not the authentication data of the authentication information received from the main controller matches the expected value or the latter history data. Generate and send to the periphery. Then, if the authentication data matches the expected value, the subsequent stage unit can similarly switch the history generation method of the subsequent stage history data generation means by the same switching method as that of the main control unit. On the other hand, the peripheral unit can perform a predetermined process in the gaming machine based on the control command received from the main control unit in accordance with the subsequent authentication result data received from the subsequent unit.

  As described above, according to the present invention, the main control unit transmits the authentication information having either one of the history data indicating the history of the control command or the individual identification value to the subsequent stage, and the authentication information having the individual identification value is transmitted. Since the history generation method for generating history data in response to transmission is switched, history data can be generated by switching the history generation method, making it difficult to analyze the history data generation method. In addition, it can be difficult to estimate whether the authentication information has history data or an individual identification value. In addition, since the post-stage unit only has to switch the history generation method of the post-stage history data in the same way as the main control unit in response to the reception of the authentication information having the individual identification value, it is easy to synchronize with the main control unit, and the authentication information is illegal. When this occurs, the history generation methods do not match, which can contribute to prevention of fraud. And since the latter part checks and authenticates the communication continuity of the control command based on the history data, it can detect unauthorized communication switching by an unauthorized control command. Can be prevented from being transmitted to the peripheral portion, which can contribute to prevention of unauthorized communication switching. Since the history generation method is switched, the continuity of the history data to be generated is lost, and unauthorized analysis of the history data used for authentication information can be made difficult. Unauthorized use can be prevented. Specifically, fraud analysis based on the relationship (corresponding relationship) between the appearance order of control commands and the appearance order of history data can be made difficult. In addition, since the latter part performs authentication processing for the main control unit and transmits the subsequent authentication result to the peripheral part, the peripheral part only needs to refer to the latter authentication result without performing the authentication process. The processing load on the peripheral CPU can be reduced. Furthermore, since the individual identification value can be stored in advance, it is not necessary to perform a complicated calculation when generating authentication information, and an increase in processing load on the main control unit can be prevented. In addition, since the latter part manages the history of control commands from the main control part, the history of control commands in the peripheral part is no longer necessary, preventing an increase in the processing burden on the peripheral part due to improved security. can do. In addition, since the peripheral unit can transfer the control command received from the main control unit to the subsequent stage unit and perform a predetermined process, the peripheral unit and the rear stage unit can perform processing simultaneously. It is possible to prevent a delay in the processing. Therefore, it is possible to confirm the communication continuity of the control command, to make it difficult to analyze the authentication information used for authentication, and to reduce the processing load on the peripheral CPU.

  In the gaming machine described above, the main control unit and the latter stage unit count the number of appearance and reception of the individual identification value, and when the number of times satisfies the switching condition, the history generation method is switched by the switching method. Since the switching timing of the generated history data and the history generation method can be further complicated, unauthorized analysis can be made more difficult.

  In the gaming machine described above, since the switching information is associated with the plurality of individual identification values of the main control unit and the plurality of expected values of the subsequent stage, the history generation method is switched based on the switching information. Since the switching timing of the generated history data and the history generation method can be further complicated, unauthorized analysis can be made more difficult. In addition, since it becomes difficult to estimate whether the authentication information has history data or an individual identification value, unauthorized use of the authentication information can be prevented.

  In the gaming machine described above, since the history data and the subsequent-stage history data indicate the history of the control command for a plurality of times, even if the number of authentication information transmissions is reduced, the control command fraud that occurred during that time is detected. Therefore, it is possible to improve the authentication accuracy. Further, since the history data is complicated, unauthorized analysis can be made more difficult.

  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 part that transmits a control command for operating the peripheral board 330, and includes a data storage unit 311, a history data generation unit 312, a selection unit 313, an authentication information generation unit 314, a switching unit 315, A control-side transmission unit 316. The main control board 310 is formed of a board different from the peripheral board 330, and is electrically connected so as to be communicable with the peripheral portion 202A of the peripheral board 330.

  The data storage unit 311 corresponds to the individual identification value storage unit of the present invention, and includes control command data (control command), authentication information, individual identification value, history generation method data (history generation method), switching, transmitted to the peripheral unit 202A. Various data such as information 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 control commands and a plurality of authentication information transmitted to the peripheral unit 202A in a time series as log data. The number of control commands and authentication information stored in the data storage unit 311 can be arbitrarily set. Further, the timing of storing the control command and authentication information in the data storage unit 311 can be arbitrarily determined at the time when it is determined, after being transmitted to the peripheral unit 202A, or the like.

  The data storage unit 311 stores one or a plurality of individual identification values. The individual identification value is a value used by the rear stage portion 202B of the peripheral substrate 330 for authentication (individual value identification) of the main control board 310 (main control section). When a plurality of individual identification values are used, different data are used. As an example of the individual identification value, there are a checksum of a plurality of types of predetermined areas in the ROM 212 of the main control unit 210, a predetermined unique value, and the like. The history generation method data indicates the history generation method used by the history data generation unit 312, and an initial value is set at the time of startup or the like, and thereafter, the switching unit 315 performs switching.

  The history data generation unit 312 corresponds to a history data generation unit of the present invention, and history data indicating a history of control commands transmitted from the main control board 310 to the peripheral part 202A of the peripheral board 330 is set as a predetermined history generation method. Generate with The history data generation unit 312 generates a history at a predetermined generation timing such as an arbitrary timing from the generation (determination) of the control command to the peripheral unit 202A of the control command in the pachinko gaming machine 100, for example. History data is generated and stored based on the method and the control command data stored in the data storage unit 311. Then, the history data generation unit 312 calculates control command data 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 a control command, for example, the number of retroactive transmission of a single control command, the retroactive range of a plurality of types of control commands, etc. Stipulate. When the history data generation unit 312 generates the history data as a checksum, the history data is a total value obtained by taking a total value of a plurality of single types of control command data or a total of a plurality of control command data. Note that the history data can use the control command for one time such as the previous time or a predetermined number of times as it is, thereby simplifying the process when generating authentication information, which will be described later.

  The history data generation unit 312 according to the present embodiment will be described with respect to a case where the history data stored in the data storage unit 311 is updated and stored in the generated history data. 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 312 generates the same history data as the individual identification value, for example, the authentication information generation unit 314 does not generate authentication information having the history data, or the transmission unit 316 The authentication information including the history data is discarded without being transmitted. Alternatively, various embodiments may be adopted in which the history data generation unit 312 is designed so as to generate history data having a value different from the individual identification value, or corresponds to bit adjustment of history data.

  The selection unit 313 corresponds to the selection unit of the present invention, and the individual identification value stored in the data storage unit (individual identification value storage unit) 311 and the history data generated by the history data generation unit (history data generation unit) 312. Either of these is selected at random. The selection unit 313 uses a random number or the like so that the selection frequency between the individual identification value and the history data becomes random. The selection unit 313 can adjust the selection frequency by setting a random number or the like. For example, by setting a random number or the like so that only one out of ten selections becomes an individual identification value and increasing the selection frequency of history data, the continuity of communication of control commands is intensively monitored. Therefore, detection of unauthorized communication switching can be expected. In the present invention, since the history generation method is switched according to the occurrence of the individual identification value, the frequency of switching the history generation method can be increased by setting the selection frequency of the individual identification value high. It is possible to increase the difficulty of a simple analyst analyzing the switching timing.

  The authentication information generation unit 314 corresponds to the authentication information generation unit of the present invention, and the identification information or history data selected by the selection unit (selection unit) 313 is the authentication information used by the subsequent unit 202B for authentication of the main control unit 201. One of the above is generated as authentication data. That is, when history data is selected by the selection unit 313, the authentication information generation unit 314 generates authentication information in which history data is set in the authentication data of the authentication information. Further, when the individual identification value is selected by the selection unit 313, the authentication information generation unit 314 generates authentication information in which the individual identification value is set in the authentication data of the authentication information. Therefore, the authentication information has authentication data, and either one of history data or individual identification value is set in the authorization data.

  The switching unit 315 corresponds to the switching unit of the present invention. When the selection unit (selection unit) 313 selects an individual identification value, the history generation method of the history data generation unit (history data generation unit) 312 is determined in advance. The plurality of history generation methods are switched by a predetermined switching method, and the history generation method data in the data storage unit 311 is set. For example, the switching unit 315 can switch between two types of history generation methods, or switch a plurality of history generation methods in order.

  The main control side transmission unit 316 corresponds to the main control side transmission unit of the present invention, and the authentication information generated by the authentication information generation unit 314 and the control command data for controlling the peripheral unit 202A are transmitted to the peripheral unit of the peripheral substrate 330. It transmits to 202A, and transmits to the back | latter stage part 202B via the peripheral part 202A. The main control side transmission unit 316 of the present embodiment transmits the control command data to the peripheral portion 202A of the peripheral substrate 330 as a control signal. Further, the main control side transmission unit 316 transmits the authentication information as an authentication information signal which is a signal different from the control signal, to the rear stage unit 202B via the peripheral unit 202A. 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 side reception unit 331, a post-stage side storage unit 332, a post-stage side history data generation unit 333, a post-stage authentication result data generation unit 334, a post-stage side transmission unit 335, and a post-stage side switching unit 336. Is configured.

  The post-stage receiving unit 331 corresponds to the post-stage receiving unit of the present invention, and receives the control command data and authentication information transmitted from the peripheral unit 202A by the main control board 310 and transferred from 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 data by receiving the control signal transferred from the peripheral unit 202A separately from the authentication information signal.

  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 commands 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. It has a storage area.

  The rear-stage storage unit 332 displays one or more individual identification values to be received from the above-described main control board 310, that is, an expected value that matches the individual identification value stored in the data storage unit 311 of the main control board 310. I remember it. As a result, if the authentication data set in the authentication information matches the expected value, the rear stage part 202B of the peripheral substrate 330 can determine that the authentication data is a regular individual identification value. Further, if the authentication data set in the authentication information does not match the expected value, it can be determined that it is not an individual identification value. The rear-stage storage unit 332 stores history generation method data similar to that of 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. An initial value is set at the time of startup or the like, and thereafter, switching is performed by the subsequent-stage switching unit 336.

  The post-stage history data generation unit 333 corresponds to the post-stage history data generation means of the present invention, and the post-stage history data indicating the history of control commands received from the main control board 310 is the same as the history generation of the main control board 310. Generate by method. The post-stage history data generation unit 333 has the same history generation method and post-stage storage as the main control board 310 at a predetermined post-stage generation timing such as when receiving a control command from the main control board 310, after receiving the control command. Based on the control command data stored in the unit 332, post-stage history data is generated and stored. In other words, the latter-stage history data generation unit 333 calculates control command data 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 data transmitted by the main control board 310 has been received, the subsequent stage history data will match the history data of the main control board 310. If not, an illegal control command will be obtained. It can be determined that data is being 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 post-authentication result data generation unit 334 corresponds to post-authentication result data generation means of the present invention, and determines whether or not the authentication data of the received authentication information matches the expected value or the peripheral history data. The main control board (main control unit) 310 is authenticated based on the above, and subsequent authentication result data indicating the authentication result is generated and transmitted to the peripheral unit 202A. That is, the latter-stage authentication result data indicates an authentication result indicating whether or not the latter-stage unit 202B has authenticated the main control board 310 (main control unit 201). Then, when the authentication data matches the post-stage history data, the post-stage authentication result data generation unit 334 sets the history data in the authentication data, and the control command used to generate the post-stage history data is valid. Since it can be determined that there is, authentication is established. Further, if the authentication data matches the expected value, the latter-stage authentication result data generation unit 334 can determine that the individual identification value is set in the authentication data and the legitimate individual identification value is received. Establish. That is, the post-authentication result data generation unit 334 establishes authentication of the main control board 310 when either the continuity of the communication state or the received individual identification value is valid. The post-authentication result data generation unit 334 may be configured to establish authentication when it is determined that both the continuity of the communication state and the received individual identification value are valid.

  The post-stage transmission unit 335 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 334 to the peripheral unit 202A. Then, the post-stage transmission unit 335 transmits the generated post-stage authentication result data to the peripheral unit 202A as a post-stage authentication result signal, for example.

  The latter-stage switching unit 336 corresponds to the latter-stage switching unit of the present invention. When the authentication data of the received authentication information matches the expected value, the history generation method of the latter-stage history data generation unit 333 is changed to the main control. Similarly to the switching unit 315 of the substrate 310, switching is performed by a predetermined switching method from a plurality of predetermined history generation methods. Therefore, since the switching unit 315 and the subsequent-stage switching unit 336 can switch the history generation method with the synchronized switching timing and the same switching method, unless the subsequent-stage unit 202B of the peripheral board 330 receives unauthorized authentication information, There is no switching to a different history generation method.

  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 transfer means of the present invention, receives authentication information and a plurality of types of control command data from the main control board 310, and transfers the received authentication information and a plurality of types of control commands to the subsequent stage unit 202B. To do. For example, when receiving the authentication information signal and the control signal corresponding to each of a plurality of types of authentication information from the main control board 310, the transfer unit 351 of the present embodiment sends the authentication information signal and the control signal to the subsequent stage unit 202B. By transmitting as it is, a plurality of types of authentication information and control command data are transferred to the subsequent stage 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 a control command from the control signal received from the main control board 310 and performs a predetermined process corresponding to the control command when the latter-stage 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. Note that the predetermined processing is performed in accordance with a control command from the main control unit 201 in the pachinko gaming machine 100, for example, processing such as loss processing, jackpot reach processing, jackpot start processing, jackpot round processing, jackpot end processing, etc. Is mentioned.

  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.

  The pachinko gaming machine 100 of the present invention transmits authentication information in which either history data or individual identification value is set from the main control board 310 to the rear stage part 202B of the peripheral board 330, and the rear stage part 202B of the peripheral board 330 is A configuration for performing authentication based on the continuity of communication of the control command based on the history data of the authentication information, and performing authentication based on the individual identification of the main control board 310 based on the individual identification value of the authentication information. Adopted. Then, the subsequent stage unit 202B of the main control board 310 and the peripheral board 330 switches the history generation method by the same switching method according to the appearance of the authentication information having the individual identification value. Since it can be changed irregularly, unauthorized analysis of authentication information can be made difficult. Therefore, even if the authentication information is independently transmitted from the main control unit 201 to the subsequent stage 202B of the peripheral substrate 330, it can be difficult to easily analyze the authentication information.

  Further, in the present embodiment, the CPU 211 of the main control board 310 is the first computer in the claims, and the CPU 241 of the peripheral part (effect control unit) 202A of the peripheral board 330 is the second computer in the claims, the latter stage of the peripheral board 330. A case where the CPU 21 of the unit 202B functions as the third computer in the claims will be described. The ROM 212 of the main control board 310 causes the first computer to function as various means such as history data generation means, selection means, authentication information generation means, switching means, main control side transmission means, etc. The main control side authentication program 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 202B of the peripheral board 330 includes the third computer in the rear side receiving means, the rear stage history data generating means, the rear stage authentication result data generating means, the rear stage side transmitting means, and the rear stage side switching means. A post-stage authentication program for functioning as various 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 status of the game ball for each winning port to the winning ball control unit 203 as a control command. The winning ball control unit 203 pays out the number of winning balls corresponding to the winning situation in accordance with the control command output from the main control unit 201.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  In the data part 1022, either the above-described history data or individual identification value is set as authentication data. The data unit 1022 of the present embodiment will be described in the case where either history data or individual identification value is set, but instead of this, the history data or individual identification value is associated with other data. The embodiment may be set in the unit 1022.

  That is, as shown in FIG. 12, the authentication information 1020 of the present embodiment is a data type K1 in which one type of “authentication command C” is set in the identification unit 1021 and history data is set in the data unit 1022. The authentication information 1020 is a data type K2 in which “authentication command C” is set in the identification unit 1021 and an individual identification value is set in the data unit 1022.

  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. When the result unit 1032 indicates that authentication is not established, the result unit 1032 has detailed data indicating details such as history data mismatch, individual identification value mismatch, and the like.

(Example of history generation method)
In the present embodiment, a case will be described in which the history data generation unit 312 and the subsequent-stage history data generation unit 333 of the main control board 310 switch the history generation method based on the history generation method information illustrated in FIG. 13. To do.

  The history generation method information shown in FIG. 13A is information used for switching between four calculation methods, for example, addition, subtraction, XOR, and XNOR. In this case, it is assumed that the control command to be calculated is predetermined. Next, the history generation method information illustrated in FIG. 13B is information used for switching four control commands, for example, a jackpot control command, a reach control command, and a loss control command. In this case, the calculation method for the corresponding control command is based on the premise that calculation methods such as addition, subtraction, XOR, and XNOR are determined in advance. Next, the history generation method information shown in FIG. 13C is information used when the control commands one, three, five, and five before the received control command are to be calculated. Similarly in this case, it is assumed that the calculation method is predetermined. Next, the history generation method information shown in FIG. 13 (d) is used to switch the retroactive number of control commands such that three received control commands are accumulated, five are accumulated, and ten are accumulated. It is used information. Similarly in this case, it is assumed that the calculation method is predetermined.

  The history data generation unit 312 and the subsequent-stage history data generation unit 333 switch a plurality of history generation methods indicated by the history generation method information with a predetermined common switching method. As an example of the switching method, there are sequentially switching from the top, specifying the switching order, specifying the switching pattern, and the like. For example, when sequentially switching the history generation method information of FIG. 13A, first, the “addition” history generation method is used, and then the next “subtraction” history generation method according to the generation of the individual identification value. Switch to Further, when the history generation method information in FIG. 13A is switched by the switching pattern, the switching pattern is switched to the first, third, second, and fourth. Thus, if the switching method can be used in common, the switching method can be arbitrarily set.

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

  When the pachinko gaming machine 100 is powered on (turned on), the main control unit 201 executes the authenticated side processing shown in FIG. 14 and based on the control command stored in the data storage unit 311 in step S1201. It is determined whether or not a control command is generated. If the main control unit 201 determines that a control command has not been generated (S1201: No), the main control unit 201 proceeds to the process of step S1203. On the other hand, if the main control unit 201 determines that a control command has been generated (S1201: Yes), in step S1202, the history generation method data in the data storage unit 311 and the control command to be generated by the history generation method. Based on the data, history data is generated and stored in the data storage unit 311, and then the process proceeds to step S 1203.

  In step S1203, the main control unit 201 determines whether it is a predetermined authentication timing. When the main control unit 201 determines that it is not the authentication timing (S1203: No), the main control unit 201 proceeds to the process of step S1211. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1203: Yes), the process proceeds to step S1204.

  In step S1204, the main control unit 201 randomly selects one of history data / individual identification value based on a random number and the like, stores the selection result in the RAM 213, and then proceeds to the processing of step S1205. Then, the main control unit 201 determines whether or not history data has been selected in step S1205. If the main control unit 201 determines that history data has been selected (S1205: Yes), in step S1206, authentication information (history) in which the authentication command C is set in the identification unit 1021 and the history data as authentication data is set in the data unit 1022. Data) 1020 is generated and stored in the data storage unit 311, and then the process proceeds to step S 1209.

  On the other hand, if the main control unit 201 determines that no history data has been selected (S1205: No), in step S1207, an authentication command C is set in the identification unit 1021, and an individual identification value as authentication data is set in the data unit 1022. The generated authentication information (individual identification value) 1020 is generated and stored in the data storage unit 311, and then the process proceeds to step S 1208. In step S1208, the main control unit 201 switches one history generation method from a plurality of predetermined history generation methods using the switching method, and the data storage unit 311 so that the switched history generation method is obtained. The history generation method data is updated, and then the process proceeds to step S1209.

  In step S1209, the main control unit 201 encrypts the authentication information 1020 generated this time using a predetermined encryption method with the subsequent unit 202B, and in step S1210, based on the encrypted authentication information 1020. The authentication information signal is generated and transmitted from the main control side transmission unit 316 to the peripheral portion 202A of the peripheral board 330, so that the authentication information signal is transmitted to the rear stage portion 202B via the peripheral portion 202A, and then the step The process proceeds to S1211. If encryption is not required between the main control unit 201 and the subsequent stage unit 202B, the processing in step S1209 is deleted, and the authentication information 1020 is transmitted as it is to the subsequent stage unit 202B via the peripheral unit 202A.

  In step S1211, 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 (S1211: 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 (S1211: Yes), the process according to this flowchart ends.

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

  When the post-stage unit 202B executes the authentication-side process illustrated in FIG. 15, in step S1301, the post-stage unit 202B determines whether the post-stage receiver unit 331 has received a control command from the main control unit 201. If the rear stage unit 202B determines that the control command has not been received (S1301: No), the process proceeds to step S1303. On the other hand, if it is determined that the control command is received (S1301: Yes), the post-stage unit 202B stores the received control command (control signal) in the post-stage storage unit 332 and the main control unit 201 in step S1302. Similarly, based on the history generation method data in the latter-stage storage unit 332 and the control command data to be generated by the history generation method, the latter-stage history data is generated and stored in the latter-stage storage unit 332. The process proceeds to 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 the latter stage unit 202B determines that the authentication information 1020 has not been received (S1303: No), the process proceeds to the process of step S1312. 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 latter 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 part 1022 of the authentication information 1020, and performs the subsequent stage. It memorize | stores in the side 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 202B determines that the authentication data is the history data (based on the determination result of whether or not the received authentication data matches the subsequent stage history data stored in the subsequent stage storage unit 332). It is determined whether or not it is subsequent stage history data). If the subsequent stage unit 202B determines that the authentication data is history data (S1305: Yes), the control command received from the main control unit 201 is valid, and the continuity of communication is valid. In step S1306, authentication based on history data for the main control unit 201 is established, post-authentication result data indicating establishment of authentication based on the history is generated and stored in the RAM 23, and then the process proceeds to step S1311.

  On the other hand, if the latter stage unit 202B determines that the authentication data is not history data (S1305: No), in step S1307, the authentication data matches the expected value stored in advance in the rear stage storage unit 332. It is determined whether or not. If the post-stage unit 202B determines that the authentication data and the expected value match (S1307: Yes), since the individual identification value received from the main control unit 201 is a regular one, in step S1308, the individual Authentication based on the identification value is established, post-authentication result data indicating establishment of authentication based on the individual identification value is generated and stored in the RAM 23 or the like, and then the process proceeds to step S1309. Then, in step S1309, the rear stage unit 202B switches one history generation method from among a plurality of predetermined history generation methods using the switching method in the same manner as the main control unit 201, and the changed history generation method. The history generation method data in the rear-stage storage unit 332 is updated so that the process proceeds to step S1311. On the other hand, if the latter part 202B determines that the authentication data does not match the expected value (S1307: No), the authentication data does not match any of the latter stage history data and the expected value, so in step S1310, 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 S1311.

  In step S1311, 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 335 to the peripheral unit 202A, and then the process proceeds to step S1312.

  The post-stage unit 202B determines whether or not the pachinko gaming machine 100 is powered off in step S1312. If it is determined that the power source is not turned off (S1312: No), the peripheral unit returns to the process of step S1301 and repeats a series of processes. On the other hand, when determining that the power is turned off (S1312: Yes), the rear stage unit 202B ends the process according to this flowchart.

  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 S1401, the peripheral unit 202A determines whether or not the control signal 1010 has been received from the main control unit 201. If the peripheral unit 202A determines that the control signal 1010 has been received (S1401: Yes), the control signal 1010 is transferred (transmitted) from the transfer unit 351 to the subsequent stage unit 202B as it is in step S1402, and then the process of step S1403 is performed. move on. In step S1403, 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 1010, and then proceeds to processing in step S1408.

  On the other hand, if it is determined that the peripheral unit 202A has not received the control signal 1010 (S1401: No), it is determined in step S1404 whether authentication information (authentication information signal) 1020 has been received from the main control unit 201. To do. If it is determined that the authentication information 1020 has been received (S1404: Yes), the peripheral unit 202A transfers (transmits) the authentication information 1020 as it is from the transfer unit 351 to the subsequent unit 202B in step S1405, and then performs the process of step S1408. Proceed to On the other hand, when it is determined that the peripheral information 202A has not received the authentication information 1020 (S1404: No), the process proceeds to step S1406.

  In step S1406, the peripheral unit 202A determines whether or not the post-authentication result signal is received from the post-stage unit 202B based on whether or not the received signal includes the identification unit 1031. If the peripheral section 202A determines that the subsequent authentication result signal has not been received (S1406: No), the peripheral section 202A proceeds to the process of step S1408. On the other hand, if the peripheral unit 202A determines that the post-authentication result signal has been received (S1406: Yes), the process proceeds to step S1407.

  In step S1407, 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 (S1407: Yes), the peripheral unit 202A stores the authentication result in the RAM 243 or the like, and then proceeds to the process of step S1408.

  In step S1408, 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 (S1408: No), the peripheral unit 202A returns to the process of step S1401 and repeats a series of processes. On the other hand, when it is determined that the power source is turned off (S1408: Yes), the peripheral unit 202A ends the process according to this flowchart.

  On the other hand, if it is determined in step S1407 that the subsequent authentication result does not indicate that the authentication is successful (S1407: No), the peripheral unit 202A outputs a notification signal from, for example, the speaker 262 (see FIG. 2) or the like in step S1409. 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.

(History generation method switching procedure example)
Next, in the pachinko gaming machine 100, an example of a procedure when the rear stage 202B of the main control board 310 and the peripheral board 330 sequentially switches between the first history generation method and the second history generation method will be described with reference to the drawing of FIG. I will explain.

  In FIG. 17, when the main control board 310, which is a person to be authenticated, transmits a control command to the peripheral part 202 </ b> A of the peripheral board 330 according to the operation of the pachinko gaming machine 100, the control command is stored in the data storage part 311 ( S1501). Then, the main control board 310 generates history data based on the transmitted control command and the first history generation method and stores it in the data storage unit 311 (S1502). On the other hand, when the peripheral part 202A of the peripheral board 330 receives the control command, the peripheral part 202A transfers the control command to the rear stage part 202B of the peripheral board 330 (S1541). Then, the peripheral unit 202A performs a predetermined process corresponding to the received control command (S1542). On the other hand, the post-stage unit 202B stores the control command received from the peripheral unit 202A in the post-stage storage unit 332 (S1571), and similarly to the main control board 310, based on the received control command and the first history generation method. Post-stage history data is generated and stored in the post-stage storage unit 332 (S1572).

  Thereafter, when the main control board 310 randomly selects the history data of the history data and the individual identification value (S1503), the main control board 310 generates authentication information 1020 having the history data as authentication data and generates a peripheral portion of the peripheral board 310. It is transmitted to 202A (S1504). On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information received from the main control board 310 to the rear stage part 202B of the peripheral board 330 (S1543). On the other hand, the post-stage unit 202B performs authentication based on the continuity of communication of control commands between the peripheral board 330 and the main control board 310 because the authentication data of the received authentication information 1020 matches the post-stage history data (S1573). ). 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 (S1574). Then, 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 to the peripheral part 202A of the peripheral board 330, the main control board 310 stores the control command in the data storage unit 311 (S1505). Then, the main control board 310 generates history data based on the transmitted control command and the first history generation method and stores it in the data storage unit 311 (S1506). On the other hand, when the peripheral part 202A of the peripheral board 330 receives the control command, the peripheral part 202A transfers the control command to the rear stage part 202B of the peripheral board 330 (S1544). Then, if the latter authentication result data indicates normality, the peripheral unit 202A performs a predetermined process corresponding to the received control command (S1545). On the other hand, the post-stage unit 202B stores the control command received from the peripheral unit 202A in the post-stage storage unit 332 (S1575), and, based on the received control command and the first history generation method, as with the main control board 310. Post-stage history data is generated and stored in the post-stage storage unit 332 (S1576).

  Thereafter, when the main control board 310 randomly selects an individual identification value among the history data and the individual identification value (S1507), the main control board 310 generates authentication information 1020 having the individual identification value as authentication data, and It transmits to the peripheral part 202A (S1508). Then, the main control board 310 switches the first history generation method to the second history generation method and stores it in the data storage unit 311 (S1509). On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information received from the main control board 310 to the rear stage part 202B of the peripheral board 330 (S1546). On the other hand, the post-stage unit 202B performs authentication based on the individual authentication of the main control board 310 because the authentication data of the received authentication information 1020 matches the expected value (S1577). 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 (S1578). Then, 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 to the peripheral part 202A of the peripheral board 330, the main control board 310 stores the control command in the data storage unit 311 (S1510). Then, the main control board 310 generates history data based on the transmitted control command and the second history generation method and stores it in the data storage unit 311 (S1511). On the other hand, when the peripheral part 202A of the peripheral board 330 receives the control command, the peripheral part 202A transfers the control command to the rear stage part 202B of the peripheral board 330 (S1547). If the post-authentication result data indicates normality, the peripheral unit 202A performs a predetermined process corresponding to the received control command (S1548). On the other hand, the post-stage unit 202B stores the control command received from the peripheral unit 202A in the post-stage storage unit 332 (S1579), and, based on the received control command and the second 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 (S1580).

  Since the history data and the latter-stage history data generated in this way are generated by the switched second history generation method, the history data and the latter-stage history data so far are different from the generation method. It is difficult to analyze fraudulently. Thereafter, the same processing is performed.

  According to the pachinko gaming machine 100 described above, the main control unit 201 transmits the authentication information 1020 having either one of the history data indicating the history of the control command or the individual identification value to the subsequent stage unit 202B, and has the individual identification value. Since the history generation method for generating history data in response to the transmission of the authentication information 1020 is switched, history data can be generated by switching the history generation method, making it difficult to analyze the history data generation method. It is possible to make it difficult to estimate whether the authentication information has history data or an individual identification value. Further, since the post-stage unit 202B only has to switch the history generation method of the post-stage history data in the same manner as the main control unit 201 in response to the reception of the authentication information 1020 having the individual identification value, it is easy to synchronize with the main control unit 201. If fraud occurs in the authentication information 1020, the history generation methods do not match, which can contribute to fraud prevention. Then, since the latter stage unit 202B is configured to confirm and authenticate the communication continuity of the control command based on the history data, it can detect unauthorized communication switching due to an unauthorized control command. A command can be prevented from being transmitted to the peripheral unit 202A, which can contribute to prevention of unauthorized communication switching. Since the history generation method is switched, the continuity of the history data to be generated is lost and it is possible to make unauthorized analysis of the history data difficult. Therefore, an unauthorized analyst illegally uses the authentication information 1020. Can be prevented. Further, since the rear stage unit 202B performs the authentication process for the main control unit 201 and transmits the subsequent stage authentication result to the peripheral unit 202A, the peripheral unit 202A only refers to the subsequent stage authentication result without performing the authentication process. Therefore, the processing load on the CPU 241 in the peripheral portion 202A can be reduced. Furthermore, since the individual identification value can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information 1020, and an increase in processing load on the main control unit 201 can be prevented. Further, since the rear stage unit 202B manages the history of control commands from the main control unit 201, the peripheral unit 202A does not require control command history management. Can be prevented from increasing. In addition, since the peripheral unit 202A can transfer the control command received from the main control unit 201 to the subsequent stage unit 202B and perform a predetermined process, the peripheral unit 202A and the subsequent stage unit 202B can perform processing simultaneously. Thus, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202A. Therefore, the communication continuity of the control command can be confirmed, the analysis of authentication information used for authentication can be made difficult, and the processing load on the CPU 241 of the peripheral portion 202A can be reduced.

  In the pachinko gaming machine 100 described above, if the history data and the latter-stage history data indicate the history of the control command for a plurality of times, even if the number of times the authentication information 1020 is transmitted is reduced, the control command fraud that has occurred during that time can be corrected. Since it can be detected, the authentication accuracy can be improved. Then, by setting the history data and the latter-stage history data to values obtained by calculating past history data, analysis by an unauthorized analyst can be made even more difficult.

(Other configuration of Example 1)
Next, an example of another configuration of the pachinko gaming machine 100 according to the first embodiment described above will be described. In addition, about the same part as the structure mentioned above, the same code | symbol is attached | subjected and only a different part is demonstrated in detail.

  The main control board 310 includes the data storage unit 311, the history data generation unit 312, the selection unit 313, the authentication information generation unit 314, the switching unit 315, the main control side transmission unit 316, and the counting unit indicated by a broken line in FIG. 317.

  The counting unit 317 corresponds to the counting unit of the present invention, counts the number of appearances of the authentication information 1020 having the individual identification value, and stores the number of appearances in the data storage unit 311. Then, a switching condition indicating whether the switching unit 315 switches the history generation method based on the number of appearances is stored as a part of a program executed by the data storage unit 311 or the main control board 310. Then, the switching unit 315 is configured to switch the history generation method as described above when the number of appearances counted by the counting unit 317 satisfies the switching condition.

  The rear stage unit 202B of the peripheral board 330 includes the rear stage side reception unit 331, the rear stage side storage unit 332, the rear stage side history data generation unit 333, the rear stage authentication result data generation unit 334, the rear stage side transmission unit 335, and the rear stage side switching unit 336. And a rear-stage counting unit 337 indicated by a broken line in FIG. The peripheral unit 202A includes the transfer unit 351, the peripheral side reception unit 352, and the processing unit 353 described above.

  The latter-stage counting unit 337 corresponds to the latter-stage counting unit of the present invention, counts the number of receptions of the authentication information 1020 having the individual identification value from the main control board 310, and stores the number of receptions in the latter-stage storage unit 332 To do. Then, the switching condition as to whether or not the subsequent-stage counting unit 337 switches the history generation method based on the number of receptions is stored as a part of the program executed by the subsequent-stage storage unit 332 and the subsequent-stage unit 202B. This switching condition is the same switching condition as that of the main control board 310. Then, the rear stage side switching unit 336 is configured to switch the history generation method as described above when the number of receptions counted by the rear stage side counting unit 337 satisfies the switching condition.

  That is, the number of appearances of the counting unit 317 is the number of pieces of authentication information 1020 having individual identification values transmitted from the main control board 310 to the peripheral board 330, and the number of receptions of the post-stage side counting part 337 is controlled by the peripheral board 330. This is the number of authentication information 1020 having the individual identification value received from the board 310. Therefore, the number of appearances counted by the counting unit 317 and the number of receptions counted by the subsequent-stage counting unit 337 are the same unless the unauthorized authentication information is generated. Therefore, the switching unit 315 and the subsequent-stage switching unit By using a common switching condition 336, the switching of the history generation method can be synchronized.

(Other processing related to transmission / reception of authentication information signal)
Below, the communication example of the said authentication information signal performed between the main control part 201 and the back | latter stage part 202B in the structure mentioned above is demonstrated. First, an example of another transmission procedure of the authentication information signal by the CPU 211 (first computer) of the main control unit 201 will be described with reference to the flowchart of FIG. Since the basic processing of the flowchart shown in FIG. 18 is the same as the flowchart shown in FIG. 14 described above, only different parts will be described.

  When the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes the authenticated side processing shown in FIG. 18, and when the processing of steps S1201 to S1207 ends, the main control unit 201 proceeds to step S1221. In step S1222, the number of appearances of the individual identification value that has appeared is counted and stored in the data storage unit 311. Then, in step S1222, it is determined whether the counted number of appearances satisfies the switching condition. When the main control unit 201 determines that the number of appearances does not satisfy the switching condition (S1222: No), the main control unit 201 proceeds to the process of step S1209 described above. On the other hand, when the main control unit 201 determines that the number of appearances satisfies the switching condition (S1222: Yes), the main control unit 201 selects one of a plurality of predetermined history generation methods in the same manner as the process of step S1208 described above. The two history generation methods are switched by the switching method, the history generation method data in the data storage unit 311 is updated so as to be the switched history generation method, and then the process proceeds to step S1209 described above. Thereafter, the processes of steps S1209 to S1211 described above are executed.

  In the present embodiment, the case where the number of appearances is continuously incremented and the switching condition is set to a multiple of 3, a multiple of 5, etc. will be described, but instead, the number of appearances every time the history generation method is switched. It can also be set as the Example which clears. Further, when the switching condition is set to an irregular number of times such as 3, 7, 11,..., For example, the switching timing of the history generation method can be further complicated.

  Next, a procedure of another reception process of the authentication information signal by the CPU 231 (second computer) of the rear stage unit 202B will be described with reference to a flowchart of FIG. Since the basic processing of the flowchart shown in FIG. 19 is the same as the flowchart shown in FIG. 15 described above, only different parts will be described.

  When the authentication unit processing shown in FIG. 19 is executed, the latter stage unit 202B ends the processing of steps S1301 to S1308. In step S1321, the subsequent stage unit 202B counts the number of times the received individual identification value is received and stores it in the subsequent stage storage unit 332. Thereafter, in step S1322, it is determined whether or not the counted number of receptions satisfies the switching condition. When determining that the number of receptions does not satisfy the switching condition (S1322: No), the subsequent stage unit 202B proceeds to the process of step S1311 described above. On the other hand, when it is determined that the number of receptions satisfies the switching condition (S1322: Yes), the rear stage unit 202B generates one history from a plurality of predetermined history generation methods as in step S1309 described above. The method is switched by the switching method, the history generation method data in the rear-stage storage unit 332 is updated so as to be the switched history generation method, and then the process proceeds to step S1312 described above. Thereafter, the processes of steps S1311-S1312 described above are executed.

  Note that the procedure shown in FIG. 16 of the first embodiment can be used as it is for the procedure of the reception process of the control signal and the post-authentication result signal performed by the CPU 241 (second computer) of the peripheral portion 202A of the peripheral substrate 330. Detailed description will be omitted.

  Next, an example of the operation of the pachinko gaming machine 100 configured as described above will be described. First, even if the main control board 310 generates the authentication information 1020 having the individual identification value, the history generation method is not immediately switched. Thereafter, the main control board 310 counts the number of appearances each time the authentication information 1020 having the individual identification value appears, and switches the history generation method when the number of appearances satisfies the switching condition. On the other hand, even if the rear stage portion 202B of the peripheral board 330 receives the authentication information 1020 having the individual identification value, the history generation method is not immediately switched. Thereafter, the peripheral board 330 counts the number of times of receiving the authentication information 1020 having the individual identification value, and switches the history generation method when the number of times of reception satisfies the switching condition.

  According to the pachinko gaming machine 100 described above, the main control unit 201 transmits the authentication information 1020 having either one of the history data indicating the history of the control command or the individual identification value to the subsequent stage unit 202B, and has the individual identification value. Since the history generation method for generating history data in response to the transmission of the authentication information 1020 is switched, history data can be generated by switching the history generation method, making it difficult to analyze the history data generation method. It is possible to make it difficult to estimate whether the authentication information has history data or an individual identification value. Further, since the post-stage unit 202B only has to switch the history generation method of the post-stage history data in the same manner as the main control unit 201 in response to the reception of the authentication information 1020 having the individual identification value, it is easy to synchronize with the main control unit 201. If fraud occurs in the authentication information 1020, the history generation methods do not match, which can contribute to fraud prevention. Then, since the latter stage unit 202B is configured to confirm and authenticate the communication continuity of the control command based on the history data, it can detect unauthorized communication switching due to an unauthorized control command. A command can be prevented from being transmitted to the peripheral unit 202A, which can contribute to prevention of unauthorized communication switching. Since the history generation method is switched, the continuity of the history data to be generated is lost and it is possible to make unauthorized analysis of the history data difficult. Therefore, an unauthorized analyst illegally uses the authentication information 1020. Can be prevented. Further, since the rear stage unit 202B performs the authentication process for the main control unit 201 and transmits the subsequent stage authentication result to the peripheral unit 202A, the peripheral unit 202A only refers to the subsequent stage authentication result without performing the authentication process. Therefore, the processing load on the CPU 241 in the peripheral portion 202A can be reduced. Furthermore, since the individual identification value can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information 1020, and an increase in processing load on the main control unit 201 can be prevented. Further, since the rear stage unit 202B manages the history of control commands from the main control unit 201, the peripheral unit 202A does not require control command history management. Can be prevented from increasing. In addition, since the peripheral unit 202A can transfer the control command received from the main control unit 201 to the subsequent stage unit 202B and perform a predetermined process, the peripheral unit 202A and the subsequent stage unit 202B can perform processing simultaneously. Thus, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202A. Therefore, the communication continuity of the control command can be confirmed, the analysis of authentication information used for authentication can be made difficult, and the processing load on the CPU 241 of the peripheral portion 202A can be reduced.

  In the pachinko gaming machine 100 described above, the rear stage 202B of the main control board 310 and the peripheral board 330 counts the number of appearance and reception of the individual identification value, and switches the history generation method when the number satisfies the switching condition. Since the switching is performed by the method, the switching timing of the generated history data and the history generation method can be further complicated, so that unauthorized analysis can be made more difficult.

  Further, in the pachinko gaming machine 100 described above, if the history data and the latter-stage history data indicate the history of the control command for a plurality of times, even if the number of times the authentication information 1020 is transmitted is reduced, Since fraud can be detected, the authentication accuracy can be improved. Then, by setting the history data and the latter-stage history data to values obtained by calculating past history data, analysis by an unauthorized analyst can be made even more difficult.

  Next, in the pachinko gaming machine 100 according to the first embodiment, when a plurality of different individual identification values are used, switching information for switching a plurality of history generation methods can be associated with each of the plurality of individual identification values. .

  For example, as shown in FIG. 20, the main control board 310 stores switching information H1 in association with the individual identification value C1 and switching information H2 in association with the individual identification value C2 in the data storage unit 311. The switching information H1 and H2 are set, for example, as “history generation method D1” and “history generation method D2,” “shift one”, “shift three”, and the like for a table indicating a plurality of history generation methods. The selection unit 313 described above randomly selects one of the three options of the history data, the individual identification value C1, and the individual identification value C2. The switching unit 315 described above uses a history generation method based on the switching information H1 when the selection unit 313 selects the individual identification value C1, and based on the switching information H2 when the selection unit 313 selects the individual identification value C2. Switch. Further, the rear stage section 202B of the peripheral board 330 stores the switching information H1 and H2 in association with the expected values B1 and B2 that match the individual identification values C1 and C2 of the main control board 310, and stores them in the rear stage storage section 332. To do. The latter-stage switching unit 336 described above switches the switching information H1 when the latter-stage authentication result data generation unit 334 establishes authentication by matching the individual identification value C1 and the expected value B1, and the latter-stage authentication result data generation unit 334. If the authentication is established by matching the individual identification value C2 with the expected value B2, the history generation method is switched based on the switching information H2.

  As described above, even if the pachinko gaming machine 100 is configured, the history generation method can be switched according to the appearance and reception of the individual identification value, so that the same operational effects as those of the first embodiment can be obtained. Further, the switching information H1 and H2 are associated with the plurality of individual identification values of the main control unit 201 and the plurality of expected values of the rear stage unit 202B, and the history generation method is switched based on the switching information H1 and H2. As a result, the switching timing of the generated history data and the history generation method can be made more complicated, and therefore unauthorized analysis can be made more difficult. In addition, since it is difficult to estimate whether the authentication information 1020 has history data or an individual identification value, unauthorized use of the authentication information can be prevented.

[Example 2]
Hereinafter, a second embodiment of the pachinko gaming machine 100 described above will be described. In addition, about the same part as the structure of Example 1 mentioned above, the same code | symbol is attached | subjected and only a different part is demonstrated in detail.

(Functional configuration of main control board and peripheral board)
First, the pachinko gaming machine 100 includes the control unit 200 shown in FIG. The control unit 200 includes a main control unit 201, an effect control unit (peripheral unit) 202A, a rear stage unit 202B, and a prize ball control unit 203. As shown in FIG. 21, the pachinko gaming machine 100 includes a main control board 310 having a function as the main control unit 201, and a peripheral board 330 having the above-described effect control unit 202A and the rear stage unit 202B. Is configured. The main control board 310 is electrically connected so as to be able to communicate with the peripheral portion 202A of the peripheral board 330.

  The main control board 310 includes the data storage unit 311, the history data generation unit 312, the switching unit 315, the main control side transmission unit 316, the first authentication information generation unit 314a, and the second authentication information generation unit 314b. Part 318.

  The first authentication information generation unit 314a corresponds to a first authentication information generation unit of the present invention, and the authentication information 1020 used by the rear stage part 202B of the peripheral board 330 for authentication of the main control board (main control part) 310 is The history data generated by the history data generation unit 312 is generated so as to have authentication data. That is, the first authentication information generation unit 314a generates the authentication information 1020 of the data type K1 shown in FIG.

  The second authentication information generation unit 314b corresponds to a second authentication information generation unit of the present invention, and is stored in the data storage unit (individual identification value storage unit) 311 when the determination unit 318 described later switches. The authentication information 1020 is generated so as to have an individual identification value as the authentication data. That is, the second authentication information generation unit 314b generates the authentication information 1020 of the data type K2 shown in FIG.

  Note that the first authentication information generation unit 314a and the second authentication information generation unit 314b may be configured separately, or may be configured as a single unit, such as the authentication information generation unit 314 described above.

  The determination unit 318 corresponds to a determination unit of the present invention, and randomly determines whether or not to switch the history generation method of the history data generation unit 312. The determination unit 318 randomly determines whether or not to switch using a random number or the like so that the probability of occurrence of switching becomes a predetermined frequency. Then, the switching unit 315 determines the history generation method of the history data generation unit (history data generation unit) 312 from among a plurality of predetermined history generation methods in response to the determination by the determination unit 318 to switch. Switching is performed by a predetermined switching method, and the history generation method data in the data storage unit 311 is set. For example, the switching unit 315 can switch between two types of history generation methods, or switch a plurality of history generation methods in order.

  The main control side transmitting unit 316 includes authentication information 1020 having history data generated by the first authentication information generating unit 314a, authentication information 1020 having a solid identification value generated by the second authentication information generating unit 314b, and a peripheral board. Each of a plurality of control commands for controlling the peripheral portion 202A of 330 is transmitted to the peripheral portion 202A of the peripheral substrate 330, so that they are transmitted from the peripheral portion 202A to the subsequent stage portion 202B. Then, the main control side transmission unit 316 transmits the authentication information as the authentication information signal to the peripheral portion 202A of the peripheral substrate 330.

  Subsequently, the peripheral portion 202A of the peripheral substrate 330 illustrated in FIG. 21 includes the transfer unit 351, the peripheral side receiving unit 352, and the processing unit 353 described above, as in the first embodiment. Similarly to the first embodiment, the post-stage unit 202B also uses the post-stage side reception unit 331, the post-stage side storage unit 332, the post-stage side history data generation unit 333, the post-stage authentication result data generation unit 334, the post-stage side transmission unit 335, and the post-stage side. A switching unit 336 is provided. As described above, the peripheral substrate 330 can be realized by the same configuration as that of the first embodiment, and thus the description thereof is omitted.

  The pachinko gaming machine 100 configured in this way transmits authentication information in which either history data or individual identification value is set from the main control board 310 to the rear stage part 202B of the peripheral board 330, and the rear stage part of the peripheral board 330 202B performs authentication based on the continuity of communication of the control command based on the history data of the authentication information, and performs authentication based on the individual identification of the main control board 310 based on the individual identification value of the authentication information. The configuration is adopted. When the main control board 310 decides to switch randomly, the history generation system is switched by the switching system and authentication information having a solid identification value is transmitted to the peripheral board 330. Since the unit 202B switches the history generation method with the same switching method in response to the reception of the authentication information having the individual identification value, the history data of the authentication information can be irregularly changed. It is possible to make unauthorized analysis of Therefore, even if the authentication information is independently transmitted from the main control unit 201 to the subsequent stage 202B of the peripheral substrate 330, it can be difficult to easily analyze the authentication information.

  Also in the second embodiment, the CPU 211 of the main control board 310 is the first computer in the claims, and the CPU 241 of the peripheral part (effect control unit) 202A of the peripheral board 330 is the second computer in the claims of the peripheral board 330. A case will be described in which the CPU 21 of the rear stage unit 202B functions as the third computer in the claims. The ROM 212 of the main control board 310 includes the history data generation means, the first authentication information generation means, the second authentication information generation means, the switching means, the main control side transmission means, the determination means, 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 202B of the peripheral board 330 includes the third computer in the rear side receiving means, the rear stage history data generating means, the rear stage authentication result data generating means, the rear stage side transmitting means, and the rear stage side switching means. A post-stage authentication program for functioning as various means is stored. That is, the authentication program of the present invention is constituted by the main control side authentication program, the peripheral side authentication program, and the subsequent stage side authentication program.

(Processing 2 concerning transmission / reception of authentication information signal)
Hereinafter, communication example 2 of the authentication information signal performed between the main control unit 201 and the rear stage unit 202B of the peripheral board 330 will be described. First, an example of the authentication information signal transmission procedure 2 performed by the CPU 211 (first computer) of the main control unit 201 will be described with reference to the flowchart of FIG.

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes the authenticated-side process shown in FIG. 22, and based on the control command stored in the data storage unit 311 in step S1601. It is determined whether or not a control command is generated. When the main control unit 201 determines that a control command has not been generated (S1601: No), the main control unit 201 proceeds to the process of step S1603. On the other hand, if the main control unit 201 determines that a control command is generated (S1601: Yes), in step S1602, the history generation method data in the data storage unit 311 and the control command that is generated by the history generation method. Based on the data, history data is generated and stored in the data storage unit 311, and then the process proceeds to step S 1603.

  In step S1603, the main control unit 201 determines whether it is a predetermined authentication timing. When the main control unit 201 determines that it is not the authentication timing (S1603: No), the main control unit 201 proceeds to the process of step S1611. On the other hand, when the main control unit 201 determines that it is the authentication timing (S1603: Yes), the process proceeds to step S1604.

  In step S1604, the main control unit 201 determines whether to switch the history generation method based on a random number or the like, stores the determination result in the RAM 213, etc., and then proceeds to the processing of step S1605. In step S1605, the main control unit 201 determines whether or not to switch is determined based on the determination result. If the main control unit 201 determines that it has not been switched (S1605: No), authentication information in which authentication command C is set in the identification unit 1021 and history data as authentication data is set in the data unit 1022 in step S1606. (History data) 1020 is generated and stored in the data storage unit 311, and then the process proceeds to step S1609.

  On the other hand, when the main control unit 201 determines that it is determined to switch (S1605: Yes), in step S1607, the identification command 102 is set in the identification unit 1021, and the individual identification value as authentication data is set in the data unit 1022. Authentication information (individual identification value) 1020 is generated and stored in the data storage unit 311, and then the process proceeds to step S 1608. In step S1608, the main control unit 201 switches one history generation method from a plurality of predetermined history generation methods using the switching method, and the data storage unit 311 so that the switched history generation method is obtained. The history generation method data is updated, and then the process proceeds to step S1609.

  In step S1609, the main control unit 201 encrypts the authentication information 1020 generated this time using a predetermined encryption method with the rear stage unit 202B of the peripheral board 330, and in step S1610, the encrypted authentication information 1020 is encrypted. An authentication information signal is generated based on the information 1020 and transmitted from the transmission unit 316 to the subsequent stage unit 202B via the peripheral unit 202A, and then the process proceeds to step S1611. If encryption is not required between the main control unit 201 and the subsequent stage unit 202B, the processing in step S1609 is deleted, and the authentication information 1020 is transmitted to the subsequent stage unit 202B as it is via the peripheral unit 202A.

  In step S <b> 1611, the main control unit 201 determines whether or not the pachinko gaming machine 100 is turned off. If the main control unit 201 determines that the power is not turned off (S1611: No), the main control unit 201 returns to the process of step S1601 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1611: Yes), the process according to this flowchart ends.

  Subsequently, the control signal and the subsequent authentication result signal received by the CPU 241 (second computer) in the peripheral portion 202A of the peripheral board 330, and the authentication performed by the CPU 21 (third computer) in the rear portion 202B. The procedure of the information signal reception process can use the process shown in FIG. 16 of the first embodiment and the authentication side process shown in FIG.

(History generation method switching procedure example 2)
Next, in the pachinko gaming machine 100, an example of a procedure in the case where the rear stage 202B of the main control board 310 and the peripheral board 330 sequentially switches between the first history generation method and the second history generation method will be described with reference to the drawing of FIG. I will explain.

  In FIG. 23, when the main control board 310 that is the person to be authenticated transmits a control command to the peripheral part 202A of the peripheral board 330 according to the operation of the pachinko gaming machine 100, the control command is stored in the data storage part 311 ( S1701). Then, the main control board 310 generates history data based on the transmitted control command and the first history generation method and stores it in the data storage unit 311 (S1702). On the other hand, when the peripheral part 202A of the peripheral board 330 receives the control command, the peripheral part 202A transfers the control command to the rear stage part 202B of the peripheral board 330 (S1741). Then, the peripheral unit 202A performs a predetermined process corresponding to the received control command (S1742). On the other hand, the post-stage unit 202B stores the control command received from the peripheral unit 202A in the post-stage storage unit 332 (S1771), based on the received control command and the first 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 (S1772).

  Thereafter, when the main control board 310 randomly determines not to switch the history generation method (S1703), it generates authentication information 1020 having history data associated in advance as authentication data without switching the history generation method. To the peripheral portion 202A of the peripheral substrate 310 (S1704). On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information received from the main control board 310 to the rear stage part 202B of the peripheral board 330 (S1743). On the other hand, the post-stage unit 202B performs authentication based on the continuity of communication of control commands between the peripheral board 330 and the main control board 310 because the authentication data of the received authentication information 1020 matches the post-stage history data (S1773). ). 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 (S1774). Then, 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 to the peripheral section 202A of the peripheral board 330, the main control board 310 stores the control command in the data storage section 311 (S1705). Then, the main control board 310 generates history data based on the transmitted control command and the first history generation method and stores it in the data storage unit 311 (S1706). On the other hand, when the peripheral part 202A of the peripheral board 330 receives the control command, the peripheral part 202A transfers the control command to the rear stage part 202B of the peripheral board 330 (S1744). If the post-authentication result data indicates normality, the peripheral unit 202A performs a predetermined process corresponding to the received control command (S1745). On the other hand, the post-stage unit 202B stores the control command received from the peripheral unit 202A in the post-stage storage unit 332 (S1775), and, similarly to the main control board 310, based on the received control command and the first history generation method. Post-stage history data is generated and stored in the post-stage storage unit 332 (S1776).

  After that, when the main control board 310 randomly selects an individual identification value among the history data and the individual identification value (S1707), the main control board 310 has an individual identification value previously associated with switching the history generation method as authentication data. The authentication information 1020 is generated and transmitted to the peripheral part 202A of the peripheral board 310 (S1708). Then, the main control board 310 switches the first history generation method to the second history generation method and stores it in the data storage unit 311 (S1709). 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 (S1746). On the other hand, the post-stage unit 202B performs authentication based on the individual authentication of the main control board 310 because the authentication data of the received authentication information 1020 matches the expected value (S1777). 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 (S1778). Then, 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 to the peripheral part 202A of the peripheral board 330, the main control board 310 stores the control command in the data storage unit 311 (S1710). Then, the main control board 310 generates history data based on the transmitted control command and the second history generation method and stores it in the data storage unit 311 (S1711). On the other hand, when the peripheral part 202A of the peripheral board 330 receives the control command, the peripheral part 202A transfers the control command to the rear stage part 202B of the peripheral board 330 (S1747). Then, if the latter authentication result data indicates normality, the peripheral unit 202A performs a predetermined process corresponding to the received control command (S1748). On the other hand, the post-stage unit 202B stores the control command received from the peripheral unit 202A in the post-stage storage unit 332 (S1779), and, based on the received control command and the second 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 (S1780).

  Since the history data and the latter-stage history data generated in this way are generated by the switched second history generation method, the history data and the latter-stage history data so far are different from the generation method. It is difficult to analyze fraudulently. Thereafter, the same processing is performed.

  According to the pachinko gaming machine 100 described above, as in the first embodiment, the main control unit 201 transmits the authentication information 1020 having either one of the history data indicating the history of the control command or the individual identification value to the subsequent stage unit 202B. Since the history generation method for generating history data is switched in response to the transmission of the authentication information 1020 having the individual identification value, the history data can be generated by switching the history generation method. Analysis of the generation method can be made difficult, and it can be made difficult to guess whether the authentication information has history data or an individual identification value. Further, since the post-stage unit 202B only has to switch the history generation method of the post-stage history data in the same manner as the main control unit 201 in response to the reception of the authentication information 1020 having the individual identification value, it is easy to synchronize with the main control unit 201. If fraud occurs in the authentication information 1020, the history generation methods do not match, which can contribute to fraud prevention. Then, since the latter stage unit 202B is configured to confirm and authenticate the communication continuity of the control command based on the history data, it can detect unauthorized communication switching due to an unauthorized control command. A command can be prevented from being transmitted to the peripheral unit 202A, which can contribute to prevention of unauthorized communication switching. Since the history generation method is switched, the continuity of the history data to be generated is lost and it is possible to make unauthorized analysis of the history data difficult. Therefore, an unauthorized analyst illegally uses the authentication information 1020. Can be prevented. Further, since the rear stage unit 202B performs the authentication process for the main control unit 201 and transmits the subsequent stage authentication result to the peripheral unit 202A, the peripheral unit 202A only refers to the subsequent stage authentication result without performing the authentication process. Therefore, the processing load on the CPU 241 in the peripheral portion 202A can be reduced. Furthermore, since the individual identification value can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information 1020, and an increase in processing load on the main control unit 201 can be prevented. Further, since the rear stage unit 202B manages the history of control commands from the main control unit 201, the peripheral unit 202A does not require control command history management. Can be prevented from increasing. In addition, since the peripheral unit 202A can transfer the control command received from the main control unit 201 to the subsequent stage unit 202B and perform a predetermined process, the peripheral unit 202A and the subsequent stage unit 202B can perform processing simultaneously. Thus, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202A. Therefore, the communication continuity of the control command can be confirmed, the analysis of authentication information used for authentication can be made difficult, and the processing load on the CPU 241 of the peripheral portion 202A can be reduced.

  In the pachinko gaming machine 100 described above, if the history data and the latter-stage history data indicate the history of the control command for a plurality of times, even if the number of times the authentication information 1020 is transmitted is reduced, the control command fraud that has occurred during that time can be corrected. Since it can be detected, the authentication accuracy can be improved. Then, by setting the history data and the latter-stage history data to values obtained by calculating past history data, analysis by an unauthorized analyst can be made even more difficult.

  Further, in the present embodiment, a case where the first authentication information generation unit 314a generates authentication information 1020 having history data in response to the determination that the determination unit 318 of the main control board 310 does not switch the history generation method will be described. did. Instead of this, after the first authentication information generation unit 314a generates the authentication information 1020 having history data, the determination unit 318 may determine whether to switch the history generation method at a predetermined timing. it can. That is, the main control board 310 normally generates authentication information 1020 having history data, and generates authentication information 1020 having an individual identification value when the determination unit 318 determines to switch. With such a configuration, it is possible to reduce the communication frequency of the individual identification value and increase the communication frequency of the history data.

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

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