  However, in the gaming machine described in Patent Document 1, a process of independently transmitting a state monitoring command at a predetermined timing is performed. Since the status monitoring command is a checksum of the control command transmitted within a predetermined period as described above, the status monitoring command and the normal control command are information that is remarkably different in data format or data amount. Therefore, in the gaming machine described in Patent Document 1, a person who performs an unauthorized act (hereinafter referred to as an unauthorized person) can easily know the transmission timing of the state monitoring command and can easily know the inspection timing for fraud detection. be able to. An unauthorized person who can know the transmission timing of the state monitoring command may acquire the state monitoring command and analyze the contents.

  In the gaming machine described in Patent Document 1, the checksum is added to the control command and transmitted. A communication error check is generally performed by adding the checksum to a control command and transmitting it. However, in the gaming machine described in Patent Document 1 in which a check sum of a control command transmitted within a predetermined period is used as a state monitoring command, an unauthorized person obtains the control command by adding the check sum to the control command. This makes it easy to analyze the contents of the status monitoring command. Specifically, as described above, an unauthorized person can easily know the transmission timing of the state monitoring command. There is a possibility that an unauthorized person who knows the transmission timing of the state monitoring command can easily analyze the contents of the state monitoring command by acquiring and comparing the control command and its checksum within a predetermined period. .

Also, in the “jackpot game”, a plurality of types of jackpot games are set. For example, in the case of “game per long”, the first grand prize opening 16 is released once (× 15 rounds) for 29.000 seconds for each round game. If it is “short win game”, the second big prize opening 17 is opened for 0.052 seconds × 1 time (× 15 rounds) for each round game. In the case of “game per development”, the second grand prize opening 17 is opened for 0.052 seconds × 3 times in the first round game, and after the second round, 29.000 seconds × 1 for each round game. Times (× 14 rounds).
In the case of “small hit”, one gaming state with a winning probability of 1 / 149.75 is set. In addition, if it is a “small hit game”, although it is not a round game, the second big prize opening 17 is opened for 0.052 seconds × 15 times. In the present embodiment, “big hit game” and “small hit game” are collectively referred to as “special game”.

  The normal symbol display device 22 is for notifying the lottery result of the normal symbol that is performed when the game ball passes through the normal symbol gate 13. As will be described in detail later, when the winning symbol is won by the normal symbol lottery, the normal symbol display device 22 is turned on, and then the second start port 15 is controlled to the second mode for a predetermined time.

  Here, “normal symbol lottery” means that when a game ball passes through the normal symbol gate 13, the normal symbol determination random number value is acquired, and the acquired normal symbol determination random value corresponds to “winning”. A process for determining whether or not the value is a random value. The lottery result of the normal symbol is not always notified immediately after the game ball passes through the normal symbol gate 13, but the normal symbol display device 22 displays a variation such as blinking of the normal symbol. When the fluctuation time elapses, the normal symbol corresponding to the lottery result of the normal symbol is stopped and displayed so that the player is notified of the lottery result.

Furthermore, if a game ball enters the first start port 14 or the second start port 15 during special symbol fluctuation display or a special game to be described later, and if a big win lottery cannot be performed immediately, a certain condition The right to win a jackpot will be withheld. More specifically, the random number value for special symbol determination acquired when the game ball enters the first start port 14 is stored as the first hold, and when the game ball enters the second start port 15 The acquired special symbol determination random number value is stored as the second hold.

[Configuration for gaming machine authentication processing]
Hereinafter, control means for realizing the authentication function that the gaming machine 1 having the above configuration has for preventing fraud will be described.
The authentication function of the gaming machine 1 according to the present embodiment is realized by the authentication of the main control unit by the peripheral unit 300 authenticating the validity of the control command transmitted from the main control unit 110. In other words, if the control command transmitted from the main control unit 110 is valid, the pachinko gaming machine 1 determines that the main control unit 110 is also valid. In the present embodiment, description will be made assuming that the effect control unit 120 of the peripheral unit 300 has a function of authenticating the main control unit 110.

  Specifically, the main control unit 110 adds the error check value generated using the control command transmitted to the last effect control unit 120 to the control command to be transmitted this time and transmits it to the effect control unit 120. . The production control unit 120 collates the error check value generated from the control command received immediately before and the error check value added to the control command received this time.

That is, in this embodiment, the error check value generation method generated next time is changed or continued from the current generation method according to the error check value generated this time.

  FIG. 5 is a functional block diagram showing a configuration related to the authentication process of the main control unit 110 constituting the pachinko gaming machine 1 according to one embodiment of the present invention. The main control unit 110 includes a control command output unit 500, an error check value generation unit 510, an addition unit 550, and a transmission unit 560. Further, the error check value generation unit 510 includes a control command storage unit 520, an error check value calculation unit 530, and a generation method determination unit 540. Each functional block configuring the main control unit 110 is configured by appropriately combining the units included in the main control unit 110 such as the main CPU 110a, the main ROM 110b, and the main RAM 110c shown in FIG.

  The control command output unit 500 generates a control command to be transmitted this time to the effect control unit 120 in order to instruct the contents of the game process performed by the effect control unit 120, and outputs the control command to the error check value generation unit 510 and the addition unit 550. To do. Specific means for realizing the function of the control command output unit 500 can be constituted by, for example, the main CPU 110a, a part of the main ROM 110b, and a part of the main RAM 110c shown in FIG. More specifically, the main CPU 110a determines and outputs a control command to be output this time based on a program stored in advance in the main ROM 110b using the main RAM 10c as a work area. The main CPU 110a sets the output control command in the transmission data storage area of the main RAM 110c.

  The error check value generation unit 510 generates an error check value by using the control command output from the control command output unit 500 last time, that is, the control command transmitted to the effect control unit 120 last time, and generates the error check value. The data is sent to the adding unit 550. Further, the error check value generation unit 510 generates an error check value to be generated next time, that is, generation of an error check value to be transmitted next time, based on the error check value generated this time, that is, the value of the error check value to be transmitted this time. Determine the method.

  Specifically, the control command storage unit 520 constituting the error check value generation unit 510 stores the control command output from the control command output unit 500. In the present embodiment, at least two of the control command transmitted this time and the control command transmitted last time may be stored. Control command storage unit 520 stores the control command transmitted this time and outputs the control command transmitted last time to error check value calculation unit 530. Specific means for realizing the function of the control command storage unit 520 is, for example, a control command storage area of the main RAM 110c shown in FIG.

  The error check value calculation unit 530 can generate and generate error check values using a plurality of error check value generation methods, in this embodiment, two error check value generation methods (hereinafter referred to as method A and method B). Based on the generation method determined by the method determination unit 540, an error check value is generated using the previously transmitted control command output from the control command storage unit 520. Further, the error check value calculation unit 530 sends the error check value generated using the previously transmitted control command to the generation method determination unit 540 and the addition unit 550. The initial value of the generation method may be determined in advance. In this embodiment, the error check value generation method is initially set to method A. Specific means for realizing the function of the error check value calculation unit 530 can be constituted by, for example, the main CPU 110a, a part of the main ROM 110b, and a part of the main RAM 110c shown in FIG. More specifically, the main CPU 110a uses the main RAM 110c as a work area and stores in advance the information on the generation method used to generate the current error check value stored in the generation method storage area of the main RAM 110c and the main ROM 110b. An error check value is generated and output based on the stored program.

  In the present embodiment, “generating an error check value using a control command” means generating an error check value using control command data that is a specific value of the control command. In this embodiment, unless otherwise specified, the term “control command” includes the meaning of control command data. The “error check value generated using the control command” is also simply referred to as “error check value of the control command”.

  In the present embodiment, the error check value generation method is not particularly limited. For example, the checksum method, CRC method, odd parity method, even parity method, group count check method, vertical parity method, vertical parity method, Alternatively, a known method such as a Hamming code method can be used.

  Based on the error check value generated by the error check value calculation unit 530 this time, the generation method determination unit 540 generates a plurality of error check value generation methods, in this embodiment, from two error check value generation methods. The generation method used to generate the error check value is determined. The generation method determination unit 540 controls the generation method of the error check value calculation unit 530 according to the determined result. Specifically, the generation method determination unit 540 generates the generation method storage area of the error check value calculation unit 530. The information on the generation method of the next error check value stored in is updated. Specific means for realizing the function of the generation method determination unit 540 can be constituted by, for example, the main CPU 110a, a part of the main ROM 110b, and a part of the main RAM 110c shown in FIG. More specifically, the main CPU 110a stores the main RAM 110c in the generation method storage area of the main RAM 110c based on the error check value generated this time and the program stored in the main ROM 110b in advance using the main RAM 110c as a work area. The information of the generation method used for generating the error check value is updated.

  Here, in the present embodiment, the generation method determination unit 540 changes the error check value generation method when the error check value generated this time satisfies a predetermined switching condition. For example, when the current error check value is generated by method A, the next generation method is switched to method B. That is, the next generation method is determined as method B. On the other hand, when the error check value generated this time does not satisfy a predetermined switching condition, the generation method determination unit 540 continues the error check value generation method. For example, when the current error check value is generated by method A, the next generation method is also switched to method A. That is, the next generation method is determined as method A. Specifically, the “predetermined switching condition” refers to whether the value of the error check value is an even number (or an odd number), whether the value of the error check value is a predetermined value or more (or less than a predetermined value), Whether the value is a specific value (or is it not a specific value) or the like.

  Note that the generation method determination unit 540 changes the next method when a predetermined switching condition is satisfied, but is not limited thereto. For example, when the error check value generated this time satisfies the predetermined condition described in the predetermined switching condition, the generation method determination unit 540 determines the next generation method as method A regardless of the current generation method, If the predetermined condition is not satisfied, the next generation method may be determined as method B. Further, when the predetermined condition is satisfied, the next generation method may be determined as the method B regardless of the current generation method, and when the predetermined condition is not satisfied, the next generation method may be determined as the method A. .

  The adding unit 550 adds the error check value generated by using the previously transmitted control command sent from the error check value calculating unit 530 to the control command to be sent this time output from the control command output unit 500, Control command information to be transmitted to the effect control unit 120 is generated. Specific means for realizing the function of the adding unit 550 can be constituted by, for example, the main CPU 110a, a part of the main ROM 110b, and a part of the main RAM 110c shown in FIG. More specifically, the main CPU 110a generates control command information based on a program stored in advance in the main ROM 110b using the main RAM 110c as a work area.

  The transmission unit 560 transmits control command information generated by adding the error check value of the control command transmitted last time to the control command transmitted this time to the effect control unit 120. Specific means for realizing the function of the transmission unit 560 can be configured by the main CPU 110a, a part of the main ROM 110b and a part of the main RAM 110c shown in FIG. 4, a transmission circuit (not shown), and the like.

  Here, the control command information is a generic name of control signals transmitted from the main control unit 110 to the effect control unit 120, and includes a control command (control command data) and an error check value added thereto. Hereinafter, the control command with an error check value is also referred to as control command information. FIG. 6 shows the format of the control command information in this embodiment. In the following description, error check values A1 and A2 are error check values generated by method A, and error check values B3 and B4 are error check values generated by method B. Of these, only error check value A2 is a predetermined switching condition. Is described as satisfying.

  As shown in FIG. 6, the control command information basically has a format in which an error check value of the control command transmitted immediately before is added to the control command. However, a predetermined initial value is added to the control command 1 transmitted first. Then, the error check value A1 generated based on the method A using the control command 1 transmitted first is added to the control command 2 transmitted second, and control command information is generated. Note that since the error check value A1 does not satisfy a predetermined switching condition, the method A is continued as the generation method. Next, the error check value A2 of the control command 2 transmitted second is added to the control command 3 transmitted third, and control command information is generated. Here, since the error check value A2 satisfies a predetermined switching condition, the next generation method is changed to the method B. Next, the error check value B3 generated based on the method B using the control command 3 transmitted third is added to the control command 4 transmitted fourth, and control command information is generated. . Similarly, when the error check value generated this time satisfies a predetermined switching condition, the generation method of the error check value to be generated next time is switched. A value is generated and control command information is generated.

  Here, the initial value is not particularly limited, and predetermined dummy data of an error check value or unique information that is unique to the gaming machine 1 can be used. Specifically, the unique information is identification information unique to the main control board such as a manufacturing number of the main control board, a serial number unique to the main CPU 110a, and a manufacturer code. Further, as the unique information, predetermined data that is a part of data stored in the ROM 110b may be used. That is, in the present embodiment, the unique information is data unique to the gaming machine 1 determined in advance. The identification information may be stored in the ROM 110b, or may be stored in other storage means provided on the main control board.

Further, the error check value generation unit 510 determines the next generation method according to whether or not the error check value generated this time satisfies a predetermined switching condition, and changes or continues the information in the generation method storage area.
The adding unit 550 adds the error check value generated by using the previously transmitted control command output from the error check value generating unit 510 to the control command to be transmitted this time output from the control command output unit 500 and performs control. Command information is generated and sent to the transmission unit 560.

Since a predetermined initial value is added to the control command received first instead of the error check value, the error checker 650 similarly performs error check using the predetermined initial value. Specific means for realizing the function of the error checking unit 650 can be configured from, for example, the sub CPU 120a, a part of the sub ROM 120b, and a part of the sub RAM 120c shown in FIG. More specifically, the sub CPU 120a checks the error check value transmitted this time against the error check value generated this time, using the sub RAM 120c as a work area, and performs error check. If the error check results do not match, that is, if the authentication is unsuccessful, the sub CPU 120a sends a notification signal for executing a notification operation for notifying that the authentication is unsuccessful to the image control unit 150 and the lamp control. To the unit 140.

After the pachinko gaming machine 1 is turned on and the main CPU 110a of the main control unit 110 performs an initial setting process, the main control unit 110 starts outputting a control command and transmits control command information to the effect control unit 120. . The receiving unit 600 receives the control command information, and outputs the control command of the received control command information to the error check value generation unit 610 and the error check value to the error check unit 650.
Error check value generation section 610 stores the control command received this time, generates an error check value using the previously received control command previously stored, and outputs the error check value to error check section 650. Further, the error check value generation unit 610 determines the next generation method according to whether or not the error check value generated this time satisfies a predetermined switching condition, and changes or continues the information in the generation method storage area.
The error checking unit 650 generates an error check using the error check value added to the control command received this time output from the receiving unit 600 and the control command received from the error check value generation unit 610 last time. Perform error checking using values.

Special figure special electricity control process ”). Details of the special figure special electric control process will be described later with reference to FIG.

In step S400, the main CPU 110a performs a normal symbol / ordinary electric accessory control process (hereinafter referred to as a “general-purpose electric power control process”) for performing the normal symbol lottery and the control of the ordinary electric accessory.
Specifically, it is first determined whether or not one or more data is set in the normal symbol hold count (G) storage area, and one or more data must be set in the normal symbol hold count (G) storage area. If this is the case, the current ordinary power transmission control process is terminated.

If 1 or more data is set in the normal symbol holding number (G) storage area, after subtracting 1 from the value stored in the normal symbol holding number (G) storage area, the data is in the normal symbol holding storage area. The normal symbol determination random numbers stored in the first storage unit to the fourth storage unit are shifted to the previous storage unit. At this time, the normal symbol determination random number value already written in the 0th storage unit is overwritten and erased.
Then, referring to the hit determination table, a process is performed to determine whether or not the normal symbol determination random number value stored in the 0th storage unit of the normal symbol hold storage area is a random value corresponding to “win”. Thereafter, the normal symbol display device 22 displays the fluctuation of the normal symbol. When the fluctuation time of the normal symbol elapses, the normal symbol corresponding to the result of the normal symbol lottery is stopped and displayed. If the random number for normal symbol determination referred to is “winning”, the start opening / closing solenoid 15c is driven to control the second start opening 15 to the second mode for a predetermined opening time.

  In step S500, the main CPU 110a performs a payout control process. In this payout control process, the main CPU 110 a refers to each prize ball counter, generates payout number designation commands corresponding to various winning ports, and transmits the generated payout number designation commands to the payout control unit 130.

Display device output processing is performed.

In step S710, the main CPU 110a performs control command transmission processing.
Specifically, the main CPU 110a generates control command information by adding an error check value (or initial value) to the control command set in the transmission data storage area of the main RAM 110c, and generates the generated control command information. It transmits to the production control unit 120. Details of the control command transmission processing will be described later with reference to FIG.

This “Special Figure Special Electric Processing Data” is a value assigned to the address of the storage area in which each subroutine of the special figure special electric control process is stored, and which subroutine is processed by referring to the special figure special electric processing data. You can identify what to do. The special figure special electricity processing data is set as necessary in each subroutine of the special figure special electricity control processing as will be described later, and the subroutine necessary for the game is appropriately processed.

  In step S302, the main CPU 110a refers to the branch address from the read special figure special processing data, and if special figure special electric treatment data = 0, the main CPU 110a moves the processing to the special symbol storage determination process (step S310). If data = 1, the process moves to the special symbol variation process (step S320), and if the special figure special electricity process data = 2, the process moves to the special symbol stop process (step S330), and the special figure special electricity process data = 3. If there is, the process moves to the jackpot game process (step S340). If the special figure special electric processing data = 4, the process moves to the big hit game end process (step S350), and if the special figure special electric process data = 5, the small hit game. The process moves to an end process (step S360).

  In the special symbol memory determination process in step S310, the main CPU 110a performs a jackpot determination process, a special symbol determination process for determining a special symbol to be stopped and displayed, a variation time determination process for determining a variation time of the special symbol, and the like. Here, the specific content of the special symbol memory determination process will be described with reference to FIG.

  FIG. 12 is a flowchart of the special symbol memory determination process performed by the main control unit 110 according to the present embodiment.

In step S311, the main CPU 110a determines whether one or more data is set in the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area.
If one or more data is not set in any storage area of the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area, the special figure special electricity processing data = 0. The special symbol variation process of this time is terminated while holding.
On the other hand, if one or more data is set in the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area, the process proceeds to step S312.

In step S312, the main CPU 110a performs a jackpot determination process.
Specifically, when one or more data is set in the second special symbol hold count (U2) storage area, 1 is calculated from the value stored in the second special symbol hold count (U2) storage area. After subtraction, various random numbers stored in the first to fourth storage units in the second special symbol random number storage area are shifted to the previous storage unit. At this time, various random values already written in the 0th storage unit are overwritten and deleted. Then, referring to the jackpot determination table, whether the special symbol determination random number value stored in the 0th storage unit of the second special symbol random value storage area is a random value corresponding to “big hit” or “small hit” It is determined whether it is a random value corresponding to.

  In addition, when one or more data is not set in the second special symbol hold number (U2) storage area and one or more data is set in the first special symbol hold number (U1) storage area, Various random numbers stored in the first to fourth storage units in the first special symbol random number storage area after subtracting 1 from the value stored in the first special symbol hold number (U1) storage area Is shifted to the previous storage unit. Also at this time, various random numbers already written in the 0th storage unit are overwritten and deleted.

However, the first special symbol storage area or the second special symbol storage area may be shifted in the order of winning in the starting opening, and the first special symbol storage area is given priority over the second special symbol storage area. You may let them.

In step S313, the main CPU 110a performs a special symbol determination process for determining the type of special symbol to be stopped and displayed.
In this special symbol determination process, when it is determined as “big hit” in the jackpot determination process (step S312), the symbol determination table is referred to and stored in the 0th storage unit of the first special symbol random value storage area. The jackpot symbol (special symbol 1 to special symbol 6) is determined based on the random number value for the jackpot symbol. In addition, when it is determined as “small hit” in the big hit determination process (step S312), the small hit stored in the 0th storage unit of the first special symbol random value storage area with reference to the symbol determination table. Based on the symbol random number value, the small hit symbol (special symbol A, special symbol B) is determined. If it is determined that the game has been “lost” in the jackpot determination process (step S312), the lost symbol (special symbol 0) is determined with reference to the symbol determination table.
Then, stop symbol data corresponding to the determined special symbol is stored in the stop symbol data storage area.

In step S314, the main CPU 110a performs special symbol variation time determination processing.

Thereafter, the variation time of the special symbol corresponding to the determined variation pattern of the special symbol is determined. Then, a process of setting a counter corresponding to the determined variation time of the special symbol in the special symbol time counter is performed.

In step S315, the main CPU 110a sets, in a predetermined processing area, variation display data for causing the first special symbol display device 20 or the second special symbol display device 21 to perform special symbol variation display (LED blinking). . As a result, when the variable display data is set in the predetermined processing area, the LED lighting / extinguishing data is appropriately created in step S600, and the created data is output in step S700. Variation display of the special symbol display device 20 or the second special symbol display device 21 is performed.

Note that the special symbol variation time counter set in step S314 is subtracted in step S110.

If it is determined that the variation time of the special symbol has elapsed, the special symbol determined in step S313 is stopped and displayed on the first special symbol display device 20 or the second special symbol display device 21. Thereby, the special symbol is stopped and displayed on the first special symbol display device 20 or the second special symbol display device 21, and the player is notified of the jackpot determination result.
When the number of high probability games (X)> 0, 1 is subtracted from the high probability game number (X) counter and updated. When the number of high probability games (X) = 0, the high probability game flag is cleared. .
Finally, the special symbol special power processing data = 1 is set to the special symbol special power processing data = 2, preparation is made to move to a special symbol stop processing subroutine, and the special symbol variation processing is terminated.

In the special symbol stop process in step S330, the main CPU 110a performs a process of determining whether the special symbol that is stopped and displayed is a “big hit symbol”, a “small bonus symbol”, or a “losing symbol”. Do.
When it is determined that the game is a jackpot symbol, the data stored in the gaming state storage area is referred to and data indicating the current gaming state is set in the gaming state buffer. Thereafter, the data (high probability game flag) and high probability game count (X) counter stored in the game state storage area (high probability game flag storage area or the like) are cleared. Further, the special figure special power processing data = 2 is set to the special figure special electric processing data = 3, preparation is made to move to the jackpot game processing subroutine, and the special symbol stop processing is ended.

In addition, when it is determined that the small winning symbol, the data stored in the game state storage area is not cleared, and the special figure special electric processing data = 2 to the special figure special electric treatment data = 5 is set. The special symbol stop process is completed by making preparations for transferring to a winning game process subroutine.
On the other hand, if it is determined that the symbol is a lost symbol, the special symbol special electric processing data = 2 is set to special special electric symbol processing data = 0, and the special symbol memory determination processing subroutine is prepared for the special symbol stop processing. finish.

In the jackpot game process of step S340, the main CPU 110a determines which jackpot of the long hit or short hit is executed, and performs a process of controlling the determined jackpot.
Specifically, first, with reference to the special electric accessory operating mode determination table, the jackpot release mode is determined based on the type of jackpot symbol (stop symbol data) determined in step S313.

Next, in order to execute the determined jackpot opening mode, the bonus game opening mode table is referred to, the opening time corresponding to the type of jackpot is set in the special game timer counter, and the first jackpot opening / closing solenoid The drive data of 16c (or the second big prize opening / closing solenoid 17c) is output to open the first big prize opening / closing door 16b (or the second big prize opening / closing door 17b). At this time, 1 is added to the round game count (R) storage area.
When a predetermined number of game balls enter during the opening or when the opening time of the big prize opening has elapsed (the number of the big prize opening (C) = 9 or the special game timer counter = 0), The output of the drive data of the big prize opening / closing solenoid 16c (or the second big prize opening / closing solenoid 17c) is stopped, and the first big prize opening / closing door 16b (or the second big prize opening / closing door 17b) is closed. Thereby, one round game is completed. This round game control is repeated 15 times.

  When the 15 round games are completed (round game count (R) = 15), the data stored in the round game count (R) storage area and the number of winning prize entrance (C) storage areas are cleared, The special figure special electric processing data = 3 is set to the special figure special electric treatment data = 4, preparation is made to move to the big hit game end processing subroutine, and the big hit game processing is ended.

In the big hit game ending process in step S350, the main CPU 110a performs a process of determining a probability game state of either a high probability game state or a low probability game state.
Specifically, with reference to the jackpot game end setting data table, based on the data stored in the game state buffer and the type of jackpot symbol (stop symbol data) determined in step S313, the high probability game Set a flag and set the number of high probability games (X). For example, in the case of the special symbol 1, the high probability game flag is set in the high probability game flag storage area, and the high probability game number (X) counter is set to 10,000 times.
After that, the special symbol special power processing data = 4 is set to the special symbol special power processing data = 0, and preparation for moving to the special symbol memory determination processing subroutine is made, and the big hit game end processing is ended.

In the small hit game process of step S360, the main CPU 110a first refers to the special electric accessory operation mode determination table, and based on the type of small hit symbol (stop symbol data) determined in step S313 above, Determine the opening mode.
Next, in order to execute the determined small winning opening mode, the large winning opening opening mode table is referred to, and the small winning opening time is set in the special game timer counter, and the second large winning port opening / closing solenoid 17c is set. The drive data is output to open the second big prize opening / closing door 17b. At this time, 1 is added to the number-of-releases (K) storage area.
When the small winning opening time elapses (special game timer counter = 0), the drive data output of the second big prize opening / closing solenoid 17c is stopped and the second big prize opening / closing door 17b is closed. The opening / closing control of the second big prize opening opening / closing door 17b is repeated 15 times.

  Then, the opening / closing control of the second grand prize opening / closing door 17b is performed 15 times, or a predetermined number of game balls enter the second big prize opening 17 (the number of times of opening (K) = 15 or the grand prize opening entrance) Number (C) = 9), in order to end the small hit game, the output of the drive data of the second large winning opening / closing solenoid 17c is stopped, the number of times of opening (K) storage area and the number of winning winning holes (C) Clear the data stored in the storage area, set special figure special electricity processing data = 5 to special figure special electricity treatment data = 0, and prepare to move to a special symbol memory judgment processing subroutine. The winning game process is terminated.

Next, control command transmission processing of the main control unit 110 will be described.
FIG. 13 is a flowchart showing a control command transmission process by the main control unit 110 according to the present embodiment.

  In the timer interrupt processing of the main control unit 110 shown in FIG. 10, when the timing of the control command transmission processing in step S710 comes, the error check value generation unit 510 outputs the current command output by the control command output unit 500 in step S711. By referring to whether or not the control command to be transmitted is set in the transmission data storage area, it is determined whether or not the control command is transmitted. If the control command is set, it is determined that it is the transmission timing of the control command, and the process proceeds to step S712. If the control command is not set, it is determined that it is not the transmission timing of the control command, and the control command transmission process is terminated. Specifically, when the control command to be transmitted this time is stored in the transmission data storage area of the main RAM 110c, the main CPU 110a determines that it is the transmission timing of the control command.

Subsequently, in step S712, the error check value calculation unit 530 acquires the control command transmitted to the previous effect control unit 120 stored in the control command storage unit 520.
Subsequently, in step S713, the error check value calculation unit 530 specifies the current generation method from the information on the generation method stored in the generation method storage area, and uses the acquired control command transmitted last time. Is generated. In addition, the error check value calculation unit 530 transmits the generated error check value to the generation method determination unit 540 and the addition unit 550.

  Subsequently, in step S714, the generation method determination unit 540 determines a generation method of the next error check value based on the error check value generated this time, and transmits the determination result to the error check value calculation unit 530. For example, when the current generation method is method A and the error check value generated this time, that is, the value of the error check value transmitted this time satisfies the predetermined switching condition, the next generation method is determined as method B.

  Subsequently, in step S715, the error check value calculation unit 530 stores the next generation method determined by the generation method determination unit 540. Specifically, according to the result determined by the generation method determination unit 540, the generation method determination unit 540 sets the next error check value generation method stored in the generation method storage area of the error check value calculation unit 530. Update information.

Subsequently, in step S716, the adding unit 550 adds the error check value of the previously transmitted control command transmitted from the error check value calculating unit 530 to the control command transmitted this time output from the control command output unit 500. The control command information is generated and transmitted to the transmission unit 560.
Subsequently, in step S717, the transmission unit 560 receives the control command information generated by the adding unit 550 and transmits the control command information to the effect control unit 120.
Subsequently, in step S718, the control command storage unit 520 stores the control command transmitted this time, and then ends the processing according to this flowchart.

  In the present embodiment, after step S717 for transmitting control command information is performed, step S718 for storing the control command transmitted this time is performed. However, the present invention is not limited to this. For example, the control command information transmission process in step S717 may be performed after the control command storage process in step S718.

  In step S718, the control command storage unit 520 stores the control command transmitted this time. However, if the control command storage area and the transmission data storage area of the main RAM 110c functioning as the control command storage unit 520 are configured identically. This step is unnecessary.

Further, the determined effect mode is set in the effect mode storage area.

In step S1540, the sub CPU 120a checks whether or not the control command stored in the received data storage area is a variation pattern designation command.
If the control command stored in the storage area for received data is a variation pattern designation command, the sub CPU 120a proceeds to step S1541 and proceeds to step S1550 if it is not a variation pattern designation command.

In step S1541, the sub CPU 120a acquires one random number value from the effect random number value updated in step S1100 (see FIG. 14), the acquired effect random number value, the received variation pattern designation command, and effect mode. Based on the effect mode set in the storage area, a variation effect pattern determination process for determining one variable effect pattern from a plurality of variable effect patterns is performed.
Specifically, in the normal effect mode, the variation effect pattern determination table is referred to, one change effect pattern is determined based on the acquired effect random number value, and the determined change effect pattern is stored in the effect pattern storage area. At the same time, in order to transmit the determined variation effect pattern information to the image control unit 150 and the lamp control unit 140, an effect pattern designation command based on the determined variation effect pattern is set in the transmission data storage area of the sub RAM 120c.

In step S1550, the sub CPU 120a checks whether or not the control command stored in the received data storage area is a symbol determination command.
If the control command stored in the received data storage area is the symbol confirmation command, the sub CPU 120a moves the process to step S1551, and moves to step S1560 if it is not the symbol confirmation command.

  In step S1551, the sub CPU 120a performs an effect symbol stop display process for setting a stop designation command for stopping the effect symbol in the transmission data storage area of the sub RAM 120c in order to stop the effect symbol 36.

In step S1560, the sub CPU 120a determines whether or not the control command stored in the received data storage area is a gaming state designation command.
If the control command stored in the received data storage area is a gaming state designation command, the sub CPU 120a moves the process to step S1561, and moves to step S1570 if it is not a gaming state designation command.

  In step S1561, the sub CPU 120a sets data indicating the gaming state based on the received gaming state designation command in the gaming state storage area in the sub RAM 120c.

In step S1570, the sub CPU 120a checks whether or not the control command stored in the received data storage area is an opening designation command.
If the control command stored in the received data storage area is an opening designation command, the sub CPU 120a moves the process to step S1571, and if not the opening command, moves the process to step S1580.

In step S1571, the sub CPU 120a performs a hit start effect pattern determination process for determining a hit start effect pattern.
Specifically, the hit start effect pattern is determined based on the opening designation command, the determined hit start effect pattern is set in the effect pattern storage area, and information on the determined hit start effect pattern is transmitted to the image controller 150 and the lamp. In order to transmit to the control unit 140, an effect pattern designation command based on the determined hit start effect pattern is set in the transmission data storage area of the sub RAM 120c.

In step S1580, the sub CPU 120a confirms whether or not the control command stored in the received data storage area is a special winning opening opening designation command.

Specifically, the winning end effect pattern is determined based on the ending designation command, the determined hit end effect pattern is set in the effect pattern storage area, and information on the determined hit end effect pattern is stored in the image control unit 150 and the lamp. In order to transmit to the control unit 140, an effect pattern designation command based on the determined winning end effect pattern is set in the transmission data storage area of the sub RAM 120c. When this process ends, the command analysis process ends.

  Hereinafter, the authentication process performed by the effect control unit 120 in step S2000 shown in FIG. 16 will be described with reference to the flowchart shown in FIG. FIG. 18 is a flowchart illustrating an example of the authentication processing procedure performed by the effect control unit 120.

  When the processing timing of the authentication process is reached in the command analysis process of the effect control unit 120 shown in FIG. 16, in step S2001, the receiving unit 600 of the effect control unit 120 stores the control command information stored in the received data storage area. Get control command and error check value from. The receiving unit 600 transmits the control command received this time to the control command storage unit 620 and the acquired error check value to the error check unit 650.

Subsequently, in step S2002, the control command storage unit 620 stores the acquired control command received this time. Specifically, the sub CPU 120a stores the control command received this time in the control command storage area of the sub RAM 120c.
Subsequently, in step S2003, the error check value calculation unit 630 acquires the control command received by the previous effect control unit 120 stored in the control command storage unit 620.
Subsequently, in step S2004, the error check value calculation unit 630 specifies the current generation method from the information on the generation method stored in the generation method storage area, and uses the acquired control command received last time. Is generated. In addition, the error check value calculation unit 630 transmits the generated error check value to the generation method determination unit 640 and the error check unit 650.

  Subsequently, in step S2005, the generation method determination unit 640 determines the next error check value generation method based on the error check value generated this time, and transmits the determination result to the error check value calculation unit 630. To do. For example, when the current generation method is method A and the error check value generated this time, that is, the error check value transmitted this time satisfies the predetermined switching condition, the next generation method is determined as method B.

  Subsequently, in step S2006, the error check value calculation unit 630 stores the next generation method determined by the generation method determination unit 640. Specifically, according to the result determined by the generation method determination unit 640, the generation method determination unit 640 determines the next error check value generation method stored in the generation method storage area of the error check value calculation unit 630. Update information.

Subsequently, in step S2007, the error checking unit 650 collates the error check value acquired in step S2001 with the error check value generated by using the control command previously received by the error check value generation unit 610, and performs error check. I do.
Subsequently, in step S2008, if the two error check values are the same as a result of the error check, the error check unit 650 determines that the validity of the control command received this time and the previous time has been successfully authenticated (step S2008). If the result of S2008 is YES), the processing according to this flowchart is terminated. If they are not the same, the error checking unit 650 determines that the control command is not valid and the authentication is unsuccessful (the result of step S2008 is NO), proceeds to step S2009, and performs error detection notification. Then, the process according to this flowchart is terminated.

  In step S2009, the effect control unit 120 determines that there is a possibility that an illegal act or a communication error has occurred, and outputs a notification signal to notify that effect. The effect control unit 120 transmits the generated notification signal to, for example, the image control unit 150, the lamp control unit 140, or a center control device that manages the pachinko gaming machine 1. Based on the received notification signal, the image control unit 150, the lamp control unit 140, and the like perform an effect that notifies that there is a possibility that an illegal act or a communication error has occurred in the pachinko gaming machine 1. This effect is, for example, causing a character that does not normally appear on the liquid crystal display device 31 to appear, or causing a character that normally appears to appear by a method different from normal. In addition, the brightness of the liquid crystal display device 31 may be changed, the color may be changed, or the lamp controller 140 may be controlled to display a predetermined lamp. In addition, voice control for outputting a predetermined voice to the image control unit 150, such as outputting a special voice such as an alarm sound from the voice output device 32, may be performed. In any case, when the employee of the game shop passes in front of the pachinko gaming machine 1, it is only necessary to be aware of the state. This effect may be an effect that the customer does not notice the state or an effect that the customer can easily notice. If the production is easily noticed by the customer, fraud can be efficiently suppressed.

  Further, the notification signal may include information on the gaming state of the pachinko gaming machine 1 such as “Big hit” and “Probability changing”. Based on the information on the gaming state, it may be determined whether or not an illegal act is performed by a center control device that manages the pachinko gaming machine 1 or the like. For example, there may be a case where winnings are concentrated during jackpots or probability fluctuations even if the winnings are concentrated. Therefore, it is better to determine whether or not there is a risk of fraudulent behavior under conditions different from other states during jackpots or probability fluctuations. Moreover, you may make it output the information regarding a gaming state as another signal, without including in a notification signal. In this case, the employee determines whether there is a risk of fraud based on both the notification signal and the information regarding the gaming state.

  In addition, also when performing an authentication process between the main control part 110 and the payout control part 130, since it is performed in the procedure similar to the authentication process between the main control part 110 and the effect control part 120, description is abbreviate | omitted. .

  As described above, in the present embodiment, the main control unit 110 stores control commands. Then, the main control unit 110 generates an error check value using the previously transmitted control command using the generation method determined based on the previously transmitted error check value, and adds it to the control command transmitted this time And transmitted to the effect control unit 120 as control command information. On the other hand, the production control unit 120 stores a control command. Then, the production control unit 120 uses the error check value included in the control command information received this time and the generation method determined based on the error check value received last time, and the error check generated using the control command received last time. Check the value against the error. That is, in this embodiment, the error check value of the control command transmitted in the past is added to the control command transmitted this time and transmitted from the main control unit 110 to the effect control unit 120.

  An error check value such as a normal checksum is added to the control command of the generation source and used for communication error check. On the other hand, the gaming machine 1 of the present embodiment adds the error check value of the control command transmitted last time to the control command transmitted this time as described above. By using such an unprecedented new and simple technique, even if an unauthorized person illegally acquires a control command and an error check value, the relationship between the control command and the error check value cannot be easily known. Therefore, according to this embodiment, fraud by an unauthorized person can be prevented and the security strength can be improved.

  In addition, the error check value of the control command transmitted last time by the main control unit 110 is added to the control command transmitted this time and transmitted, and the effect control unit 120 performs authentication processing, whereby the validity of the control command received this time is verified. And the validity of the control command received last time, that is, the control command from which the error check value added this time is generated can be authenticated. That is, the continuity of the control command can be authenticated. Furthermore, since the continuity of the control command can be authenticated, it can be authenticated that the main control unit 110 is continuously operating correctly.

  Further, in this embodiment, an error check value is added to each control command and transmitted from the main control unit 110 to the production control unit 120, and the production control unit 120 performs an authentication process for each control command. Can be inspected.

  In addition, the gaming machine 1 of the present embodiment normally uses an error check value used for communication error check as a check value for detecting fraud. In this way, by using the error check value conventionally used for the communication error check, it is possible to prevent fraud by an unauthorized person with a simple configuration without providing a means for separately generating a check value for performing the error check value. Can be prevented, and the security strength can be improved. That is, in a situation where the resources of the main control board of the gaming machine are limited, it is possible to suppress an increase in processing load on the main control board while improving the security strength.

  Further, in the gaming machine 1 of the present embodiment, the generation method determination unit 640 of the main control unit 110 determines the generation method of the error check value to be transmitted next from a plurality of generation methods based on the value of the error check value to be transmitted this time. Has been decided. That is, the generation method determination unit 640 is a determination unit that determines a method for generating an error check value to be transmitted this time. In the gaming machine 1 of this embodiment, when the value of the error check value transmitted this time satisfies a predetermined switching condition, the next error check value generation method is changed. As a result, even if an unauthorized person illegally acquires a control command and a plurality of error check values added thereto, it is impossible to know the change timing of the error check value generation method. It is possible to make the correspondence relationship difficult to analyze and to make fraud.

<Second Embodiment>
Hereinafter, a second embodiment according to an embodiment of the gaming machine of the present invention will be described. The gaming machine 1 according to the first embodiment stores the control command in order to generate the control command information by adding the error check value of the previously transmitted control command to the control command transmitted this time, and already stores the control command.

[Configuration for gaming machine authentication]
FIG. 19 is a functional block diagram illustrating a configuration related to the authentication process of the main control unit 110 configuring the pachinko gaming machine according to the present embodiment. The main control unit 110 includes a control command output unit 500, an error check value generation unit 810, an addition unit 550, and a transmission unit 560. Further, the error check value generation unit 810 includes an error check value calculation unit 820, an error check value storage unit 830, and a generation method determination unit 840. Each functional block configuring the main control unit 110 is configured by appropriately combining the units included in the main control unit 110 such as the main CPU 110a, the main ROM 110b, and the main RAM 110c shown in FIG.

  Control command output unit 500 generates a control command to be transmitted this time to effect control unit 120 and outputs the command to error check value generation unit 810 and addition unit 550. The adding unit 550 adds the error check value generated by using the previously transmitted control command sent from the error check value generating unit 810 to the control command to be sent this time output from the control command output unit 500, Control command information to be transmitted to the effect control unit 120 is generated. Transmission unit 560 transmits control command information to effect control unit 120.

  The error check value calculation unit 820 can generate an error check value with a plurality of error check value generation methods, in this embodiment two error check value generation methods (method A and method B), and a control command output unit. Using the control command to be transmitted this time output from 500, an error check value is generated by each of the plurality of generation methods. That is, a plurality of types of error check values corresponding to each of a plurality of generation methods are generated. In the present embodiment, two types of error check values are generated by each of the two types of generation methods of method A and method B. Further, the error check value calculation unit 820 transmits the generated multiple types of error check values to the error check value storage unit 830. Specific means for realizing the function of the error check value calculation unit 820 can be constituted by, for example, the main CPU 110a, a part of the main ROM 110b, and a part of the main RAM 110c shown in FIG. More specifically, the main CPU 110a generates and outputs an error check value based on a program stored in the main ROM 110b using the main RAM 110c as a work area.

  The error check value storage unit 830 stores a plurality of types of error check values output from the error check value calculation unit 820 as one set. In the present embodiment, it is only necessary to store at least two sets of the error check value generated this time and the error check value generated last time. Further, the error check value storage unit 830 includes a generation method storage area in which information on the type of error check value to be transmitted this time is stored, and an error check to be transmitted this time based on the information stored in the generation method storage area The value (error check value of the control command transmitted last time) is output to generation method determining section 840 and adding section 550. Specific means for realizing the functions of the error check value storage unit 830 include, for example, an error check value storage area that is a part of the main CPU 110a, the main ROM 110b, and the main RAM 110c shown in FIG. Area.

  Based on the error check value transmitted this time (error check value of the control command transmitted last time) received from the error check value storage unit 830, the generation method determination unit 840 uses any kind of generation method as the error check value to be transmitted next time. Decide whether to use the generated error checking value. That is, the type of error check value to be transmitted next time is determined. In other words, the generation method determination unit 840 determines a method for generating an error check value to be transmitted next time from a plurality of error check value generation methods based on the error check value transmitted this time. Hereinafter, it is referred to as determining the generation method that the generation method determining unit 840 determines which type of error check value generated by the next generation error check value to be used.

  The generation method determination unit 840 controls the generation method of the error check value storage unit 830 according to the determined result. Specifically, the generation method determination unit 840 generates the generation method storage area of the error check value storage unit 830. The information indicating the generation method of the error check value to be transmitted next time, that is, the information of the generation method (type) of the error check value to be transmitted next time is updated. Specific means for realizing the function of the generation method determination unit 840 can be constituted by, for example, the main CPU 110a, a part of the main ROM 110b, and a part of the main RAM 110c shown in FIG.

  Here, in the present embodiment, like the generation method determination unit 540, the generation method determination unit 840 changes the error check value generation method when the error check value transmitted this time satisfies a predetermined switching condition. For example, if the current error check value is generated by method A, the type of error check value to be transmitted next time is switched to that generated by method B. That is, the type of the next error check value generation method is determined. On the other hand, when the error check value transmitted this time does not satisfy the predetermined switching condition, the generation method determination unit 540 continues the error check value generation method. For example, when the current error check value is generated by the method A, the next generation method generated by the method A is continuously used.

  Note that the generation method determination unit 840 changes the type of the next error check value when a predetermined switching condition is satisfied, but is not limited thereto. For example, when the error check value transmitted this time satisfies the predetermined condition described in the predetermined switching condition, the generation method determination unit 840 sets the method for generating the error check value to be transmitted next time regardless of the current generation method. If the predetermined condition is not satisfied, the generation method of the error check value to be transmitted next time may be determined as the method B. If the predetermined condition is satisfied, the error check value generation method to be transmitted next time is determined as method B regardless of the current generation method, and if the predetermined condition is not satisfied, the error check value generation method to be transmitted next time is determined. The method A may be determined.

Based on whether or not it is satisfied, it is determined which type of generation method is used for the next error check. That is, the type of error check value used for the next error check is determined. In other words, the generation method determination unit 940 determines a generation method of an error check value used for the next error check from a plurality of error check value generation methods based on the error check value used for the current error check. Hereinafter, it is referred to as determining the generation method that the generation method determination unit 940 determines which type of error check value generated in the next error check is used.

[Game machine operation processing]
Next, an operation process of the pachinko gaming machine having the above configuration will be described with reference to the drawings.
In the present embodiment, the process by the main control unit 110 is different from the first embodiment only in the control command transmission process. Therefore, hereinafter, the control command transmission process will be described. FIG. 21 is a flowchart illustrating an example of a procedure of control command transmission processing by the main control unit 110.

  When the timing of the control command transmission process is reached in the timer interrupt process of the main control unit 110 shown in FIG. 10, the error check value generation unit 810 outputs the control command to be transmitted this time output by the control command output unit 500 in step S721. Is determined in the transmission data storage area, it is determined whether the transmission timing of the control command is present. If the control command is set, it is determined that it is the transmission timing of the control command, and the process proceeds to step S722. If the control command is not set, it is determined that it is not the transmission timing of the control command, and the control command transmission process is terminated. Specifically, when the control command to be transmitted this time is stored in the transmission data storage area of the main RAM 110c, the main CPU 110a determines that it is the transmission timing of the control command.

Subsequently, in step S722, the error check value calculation unit 820 acquires the control command to be transmitted this time from the control command output unit 500. Then, using this control command, an error check value is generated by each of method A and method B, which are two error check value generation methods, and transmitted to error check value storage section 830.
Subsequently, in step S723, the error check value storage unit 830 stores a plurality of types of error check values output from the error check value calculation unit 820 as one set in the error check value storage area.

  Subsequently, in step S724, the error check value storage unit 830 determines the error based on the generation method information determined by the generation method determination unit during the previous control command transmission process and stored in the generation method storage area. From the two types of error check values generated using the previously transmitted control command stored in the check value storage area, the type of error check value to be transmitted this time is acquired. That is, an error check value generated by the type of generation method determined in the previous control command transmission process is acquired. Then, the acquired error check value is transmitted to the generation method determination unit 840 and the addition unit 550.

Subsequently, in step S725, the adding unit 550 adds the error check value of the previously transmitted control command transmitted from the error check value storage unit 830 to the control command transmitted this time output from the control command output unit 500. The control command information is generated and transmitted to the transmission unit 560.
Subsequently, in step S <b> 726, the transmission unit 560 receives the control command information generated by the addition unit 550 and transmits the control command information to the effect control unit 120.

  Subsequently, in step S727, the generation method determination unit 840 determines a generation method of an error check value to be transmitted next time based on the error check value generated this time, and stores the determination result in the error check value storage unit 830. Send. For example, if the error check value transmitted this time is generated by the method A and the value of the error check value transmitted this time satisfies a predetermined switching condition, the method of generating the error check value to be transmitted next time is determined by the method B. And

  Subsequently, in step S728, the error check value storage unit 830 stores information on the generation method of the error check value to be transmitted next time determined by the generation method determination unit 840, and ends the processing according to this flowchart. Specifically, according to the result determined by the generation method determination unit 540, the generation method determination unit 540 generates the error check value to be transmitted next time stored in the generation method storage area of the error check value calculation unit 530. Update the information.

  In this embodiment, after performing step S726 for transmitting control command information, step S727 for determining a method for generating an error check value to be transmitted next time, and step S728 for storing a method for generating an error check value to be transmitted next time. However, it is not limited to this. For example, after step S727 and step S728 are performed, the control command information transmission process of step S726 may be performed.

  Hereinafter, the process of the production control unit 120 will be described. In the present embodiment, the processing by the effect control unit 120 is different from the first embodiment only in the authentication processing. Therefore, the authentication process by the effect control unit 120 will be described below. Hereinafter, the authentication process performed by the effect control unit 120 in step S1502 illustrated in FIG. 16 will be described with reference to the flowchart illustrated in FIG. FIG. 22 is a flowchart illustrating an example of the authentication process performed by the effect control unit 120.

  When the processing timing of the authentication process is reached in the command analysis process of the effect control unit 120 shown in FIG. 16, in step S2011, the receiving unit 600 of the effect control unit 120 controls the control command information stored in the received data storage area. Get control command and error check value from. The receiving unit 600 transmits the control command received this time to the error check value calculation unit 920 and the acquired error check value to the error check unit 650.

Subsequently, in step S2012, the error check value calculation unit 920 acquires the control command received this time from the receiving unit 600, and uses this control command to generate method A and method that are two error check value generation methods. Each of B generates an error check value and transmits it to the error check value storage unit 930.
Subsequently, in step S2013, the error check value storage unit 930 stores a plurality of types of error check values output from the error check value calculation unit 920 as one set in the error check value storage area.

  Subsequently, in step S2014, the error check value storage unit 930 determines the error based on the generation method information determined by the generation method determination unit 940 and stored in the generation method storage area during the previous authentication process. From the two types of error check values generated using the previously received control command stored in the value storage unit 930, the type of error check value used for the current error check is acquired. That is, an error check value generated by the type of generation method determined in the previous authentication process is acquired. Then, the acquired error check value is transmitted to the generation method determination unit 940 and the error check unit 650.

  Subsequently, in step S2015, the generation method determination unit 940 determines an error check value generation method used for the next error check based on the value of the error check value used for the current error check, and sets the error in the determination result. It transmits to the inspection value storage unit 930. For example, when the error check value used for the current error check is generated by the method A and the current error check value satisfies a predetermined switching condition, the error check value used for the next error check is generated. It is assumed that the method is generated by method B.

  Subsequently, in step S2016, the error check value storage unit 930 stores information on the error check value generation method used for the next error check determined by the generation method determination unit 940. Specifically, according to the result determined by the generation method determination unit 940, the generation method determination unit 940 stores an error in the next error check stored in the generation method storage area of the error check value storage unit 930. Information on the generation method (type) of the error check value acquired from the check value storage unit 930 is stored.

Subsequently, in step S2017, the error checking unit 650 collates the error check value acquired in step S2011 with the error check value generated using the control command previously received by the error check value generating unit 910, and performs error check. Do.
Subsequently, in step S2018, if the two error check values are the same as a result of the error check, the error check unit 650 determines that the authentication of the validity of the control command received this time and the previous time is successful (step S2018). If the result of S2018 is YES), the processing according to this flowchart is terminated. If they are not the same, the error checking unit 650 determines that the control command is not valid and the authentication is unsuccessful (the result of step S2018 is NO), proceeds to step S2019, and notifies error detection. Then, the process according to this flowchart is terminated. The error detection notification method is the same as in the first embodiment.

  In the present embodiment as well, as in the first embodiment, when the authentication process is performed between the main control unit 110 and the payout control unit 130, the authentication between the main control unit 110 and the effect control unit 120 is performed. Since the procedure is almost the same as the processing, the description is omitted.

  As described above, in the gaming machine 1 of the present embodiment, the main control unit 110 generates and stores an error check value for the control command. The main control unit 110 adds the error check value generated by the type of generation method determined based on the error check value transmitted last time to the control command to be transmitted this time, and sends it to the effect control unit 120 as control command information. Send. On the other hand, the production control unit 120 generates and stores an error check value for the received control command. Then, the production control unit 120 checks the error of the control command received last time, which is generated by the generation method determined based on the error check value included in the control command information received this time and the error check value received last time. Check the value against the error. That is, similarly to the first embodiment, the gaming machine according to the present embodiment adds the error check value of the control command transmitted in the past to the control command to be transmitted this time and transmits it from the main control unit 110 to the effect control unit 120. doing. The gaming machine of the present embodiment configured as described above can obtain the same effects as the gaming machine 1 of the first embodiment.

  In the present embodiment, the generation method determination unit determines the generation method (controls the type) of the error check value output from the error check value storage unit, but is not limited thereto. For example, the generation method determination unit may control the generation method of the error check value to be generated next time with respect to the error check value calculation unit. In this case, the error check value calculation unit includes a generation method storage area, stores information on a generation method of an error check value to be generated next time, specifies an error check value generation method based on this information, and generates an error. Generate test values. When configured in this way, the error check value storage unit needs to store only one type of error check value.

  As mentioned above, although each embodiment which is an example of the game machine of this invention was described in detail, the game machine of this invention is not limited to the said embodiment. For example, in the above embodiment, the generation method of the error check value to be transmitted next time is determined according to the value of the error check value to be transmitted this time. However, the present invention is not limited to this, and a generation method of error check values to be transmitted after m (m is an integer of 2 or more) may be determined according to the error check value to be transmitted this time. In this case, the error check value generation unit stores m generation method information in the generation method storage area, refers to the information on the current generation method from the stored generation method information, The generation method of the error check value to be transmitted (used for error check this time) may be determined. Specifically, for example, an m-bit shift register is provided, and 0 corresponds to the method A and 1 corresponds to the method B, and information on the generation method is stored in each bit of the shift register. Then, the error check value generation unit refers to the 1-bit value of the shift register when determining the generation method of the error check value to be transmitted this time (used for the current error check), and generates the error check value to be transmitted this time Specify the method. Further, the error check value generation unit determines a generation method of an error check value to be transmitted m times (used for error check after m times) based on the value of the error check value to be transmitted this time (used for error check this time). Then, the value of the shift register is updated, and the information on the determined generation method is set in the m bits of the shift register.

  Specifically, in the case of m = 2, that is, in accordance with the value of the error check value transmitted this time, the configuration of the control command information in the case of determining the generation method of the error check value to be transmitted two times later is shown in FIG. It explains using. In the following description, error check values A1 and A2 are error check values generated by method A, and error check values B3, B4, and B5 are error check values generated by method B. Of these, only error check value A2 is a predetermined value. A description will be given assuming that the switching condition is satisfied.

  As shown in FIG. 23, the control command information basically has a format in which an error check value of the control command transmitted immediately before is added to the control command. However, a predetermined initial value is added to the control command 1 transmitted first. Then, the error check value A1 generated based on the method A using the control command 1 transmitted first is added to the control command 2 transmitted second. Next, since the initial value does not satisfy the predetermined switching condition, the generation method is the method A, and the error check value A2 of the control command 2 transmitted second is included in the control command 3 transmitted third. In addition, control command information is generated. Here, since the error check value A2 satisfies a predetermined switching condition, the next generation method is changed to the method B. Next, since the error check value A1 does not satisfy the predetermined switching condition, the generation method is the method A, and the control command 4 transmitted fourth is the method using the control command 3 transmitted third. The error check value A3 generated based on A is added, and control command information is generated. Since the error check value A2 satisfies a predetermined switching condition, the generation method is changed to the method B, and the control command 5 transmitted fifth is changed to the method B using the control command 4 transmitted fourth. Based on the error check value B4 generated based on this, control command information is generated. Similarly, when the error check value generated this time satisfies a predetermined switching condition, the error check value generated by continuing the generation method when the error check value generation method to be generated one after another is not satisfied. Is generated. That is, based on the value of the error check value generated this time, an error check value generation method to be generated one after another is determined.

  As described above, it is difficult to analyze the relationship between the control command and the error check value added thereto by determining the generation method of the error check value to be transmitted after m in accordance with the value of the error check value transmitted this time. It can be. Thereby, even if an unauthorized person acquires control command information, it can be made more difficult to perform an unauthorized act.

  In addition, when determining the generation method of the error check value to be transmitted after m in accordance with the value of the error check value transmitted this time, the error check value generation method is changed while the m control commands are transmitted. The maximum number of times (the number of times less than m) can be determined in advance between the main control unit and the peripheral unit. For example, if m = 3 and the maximum number of times of switching is 2, even if three error check values continuously satisfy a predetermined switching condition, the error check value generation method is changed twice, but the third time An error check value of the same generation method as the second time is transmitted. In this way, by setting the maximum number of switchings to less than m, there are cases in which the test value generation method does not change even if the error check value satisfies a predetermined switching condition. It is possible to make it difficult to analyze the regularity of changing the inspection value generation method, and to improve the security strength.

  In the above embodiment, two error check value generation methods, method A and method B, have been described as examples. However, the present invention is not limited to this, and there are three or more error check value generation units. The error check value may be generated by a plurality of generation methods. In this case, the generation method storage area of the error check value generation unit may identify each of the generation methods in association with identification information.

  Further, in the above embodiment, the error check value generation unit generates an error check value to be transmitted (used for error check) next time (used for error check) based on the error check value to be transmitted this time (used for error check). The method is determined, the generation method information is stored in the generation method storage area, and the error check value generation method to be transmitted is specified in accordance with this information. However, the present invention is not limited to this. For example, based on the error check value transmitted this time (used for error check), information on whether to switch the generation method of the error check value to be transmitted (used for error check) next time (used after error check) is stored in the generation method It is possible to specify whether or not to switch the generation method of the error check value to be transmitted next time from the current generation method with reference to the information on whether or not to switch this information. In any case, the error check value generator determines the error check value generation method based on the error check value transmitted this time.

  Further, in this case, when switching the generation method of the error check value transmitted after m (used for error check), refer to the generation method of the error check value transmitted after m-1 (used for error check). , A method for generating an error check value to be transmitted after m (used for error checking) is determined, but is not limited thereto, and a method for generating an error check value to be transmitted after mq (for error checking) is determined. You may make it determine with reference (q is a positive integer less than m). That is, when determining the generation method of the error check value (used for error checking) to be transmitted this time, the method is not limited to referring to the generation method of the error check value transmitted previously (used for error checking). , An error check value generation method (used for error check) transmitted q times ago may be referred to. For example, when q = 2 and the information indicating whether or not to switch the generation method of an error check value to be transmitted m (after error check) indicates that the error check value is to be switched, it is transmitted m−2 (error check) Refer to the error check value generation method (used for the error check value generation method that has already been transmitted two times before (used for error check)). The error check value generation method is switched with respect to the generation method. That is, referring to the generation method of the error check value transmitted two times before (used for error check), and when this generation method is method A, the error check value generation method transmitted this time (used for error check) Is switched to method B.

  An example of using an m-bit shift register as a configuration for determining a generation method of an error check value to be transmitted m times later (used for error check) based on an error check value transmitted this time (used for error check). However, the present invention is not limited to this, and may be configured to be realized by hardware and software based on various other configurations and methods. For example, the error check value generation unit is provided with an increment counter or a decrement counter for m or the maximum number of switching times, and the counter when the error check value transmitted this time (used for error check) satisfies a predetermined switching condition. Are activated one by one. The counter value may be updated every time the error check value is generated, and the generation method may be switched when the counter value becomes m or 0.

  Further, in the above embodiment, the error check value generation unit generates an error check value to be transmitted (used for error check) next time (used for error check) based on the error check value to be transmitted this time (used for error check). Although the method has been determined, the present invention is not limited to this. The error check value generation unit may determine a generation method of an error check value to be transmitted this time (used for error check) based on the value of the error check value generated this time. For example, the error check value generation unit stores the information of the current generation method in the generation method storage area, and the control command transmitted (received) last time by the generation method specified based on the information of the generation method Is used to generate an error check value. Then, the error check value generation unit confirms whether or not the generated error check value satisfies a predetermined switching condition, and if it satisfies, the error check value generation method to be transmitted this time (used for error check) And the information on the current generation method stored in the generation method storage area is updated. That is, the error check value generation unit determines a generation method of an error check value added to the control command to be transmitted this time (used for the current error check) based on a predetermined agreement.

  In the above embodiment, as shown in FIG. 6, the control command transmitted this time is added with the control command transmitted last time, that is, the error check value of the control command transmitted immediately before, to obtain control command information. However, the present invention is not limited to this, and the control command information is generated by adding the error check value of the control command transmitted n (n is an integer of 2 or more) previous to the control command transmitted this time. Also good. In this case, the control command to be transmitted to the 1st to n-th items may be obtained as control command information by adding dummy data of an error check value, an ID unique to the gaming machine or the like as an initial value. Further, in the case of the gaming machine of the first embodiment, it may be configured so that at least n control commands can be stored. Further, in the case of the gaming machine of the second embodiment, it may be configured so that at least n error check values can be stored.

  Specifically, the configuration of the control command information when n = 2, that is, when the error check value of the control command transmitted two times before is added to the control command transmitted this time will be described with reference to FIG. . As shown in FIG. 24, the control command information basically has a format in which an error check value of the control command transmitted two times before is added to the control command. However, a predetermined initial value 1 is added to the control command 1 transmitted first. An initial value 2 is added to the control command 2 transmitted second. Then, the error check value 1 of the control command 1 transmitted first is added to the control command 3 transmitted third, and control command information is generated. Similarly, the error check value 2 of the control command 2 transmitted second is added to the control command 4 transmitted fourth, and control command information is generated. Thereafter, control command information is generated in the same manner.

  In this way, by adding the error check value of the control command transmitted n times before to the control command transmitted this time, the relationship between the control command and the error check value added thereto may be made more difficult to analyze. it can. Thereby, even if an unauthorized person acquires control command information, it can be made more difficult to perform an unauthorized act.

  In the above embodiment, the error check value is generated by using both the MODE and DATA data of the control command. However, the gaming machine of the present invention is not limited to this. For example, the gaming machine of the present invention may generate the error check value using only the MODE information of the control command, that is, 1-byte data for identifying the control command classification.

  Furthermore, the gaming machine of the present invention may generate an error check value using a control command and an error check value (control command information) added thereto. As a result, the error check value transmitted this time includes the information of the error check value added so far, that is, the control command information transmitted so far. Therefore, since the error check value includes information on the transmission history of the control command, even if an unauthorized person acquires some control command information, the error check value cannot be analyzed. Security strength can be improved. Further, since the error check value includes information on the transmission history of the control command, the continuity of the control command can be verified.

  Specifically, a case where an error check value is generated using control command information will be described. FIG. 25 is an explanatory diagram showing the format of control command information in the present embodiment. In the following description, it is assumed that the generation method is set to method A. As shown in FIG. 25, the control command information basically has a format in which an error check value of the control command information transmitted immediately before is added to the control command. However, a predetermined initial value is added to the control command 1 transmitted first. The control command 2 transmitted second is added with the control command information transmitted first, that is, the error check value A1 generated from the control command 1 and the initial value, and the control command information is generated. . Similarly, the control command 3 transmitted third is added with the control command information transmitted second, that is, the error check value A2 generated from the control command 2 and the error check value 1, and the control command is transmitted. Information is generated. Thereafter, control command information is generated in the same manner. As described above, the error check value added to the control command to be transmitted this time is generated using all the control command information that has already been transmitted including the initial value.

  A specific configuration for generating an error check value using a control command and an error check value added thereto, that is, control command information, is as follows. In the first embodiment, for example, in the error check value generation unit, the error check value transmitted this time (used for error check this time) generated from the control command information transmitted (received) last time is used from the error check value calculation unit as a control command. What is necessary is just to comprise so that it may output to a memory | storage part, and you may memorize | store in the control command memory | storage part as control command information combining the control command transmitted this time (received) and the output error check value. In the second embodiment, for example, in the error check value generation unit, the error check value transmitted this time (used for error check this time) generated from the control command information transmitted (received) last time is used from the error check value storage unit. What is necessary is just to comprise so that an error check value calculating part produces | generates an error check value using the control command output to the error check value calculating part and transmitted (received) this time and the output error check value.

  Note that the gaming machine according to the present invention is configured to determine the generation method of the error check value to be transmitted after m according to the value of the error check value transmitted this time and the error check using the control command information transmitted in the past. You may combine the structure which produces | generates a value.

  The gaming machine of the present invention may generate an error check value using a plurality of control commands or control command information transmitted in the past. As a result, the relationship between the control command and the error check value added thereto can be made more difficult to analyze, and even if an unauthorized person obtains the control command information, it can be made more difficult to perform fraud. .

  As a specific configuration for generating an error check value using a plurality of control commands transmitted in the past, for example, the following can be considered. The error check value generation unit includes a control command storage unit that stores a plurality of control commands output from the control command output unit, and the error check value calculation unit uses the plurality of control commands output from the control command storage unit. What is necessary is just to comprise so that an error check value may be produced | generated.

  In addition, a specific configuration for generating an error check value using a plurality of control command information transmitted in the past may be as follows, for example. The error check value generation unit includes a control command information storage unit that stores a plurality of control commands output from the control command output unit and the error check values generated by the error check value calculation unit as control command information. What is necessary is just to comprise so that an error check value calculating part produces | generates an error check value using the some control command output from the memory | storage part.

  As described above, the gaming machine of the present invention adds an error check value generated using at least a predetermined control command output in the past to the control command transmitted this time, to the control command output this time. As a result, the relationship between the control command and the error check value added thereto can be made more difficult to analyze, and even if an unauthorized person obtains the control command information, it is difficult to perform fraud.

  Note that the gaming machine of the present invention may generate an error check value including a control command transmitted this time, in addition to a control command transmitted in the past, or a control command transmitted in the past and its error check value. Thereby, the communication error check of the control command received this time can be performed in real time using the error check value added to the control command received this time.

  As a specific configuration for generating the error check value including the control command to be transmitted this time, for example, the following can be considered. There is provided a storage unit for storing a plurality of control commands or control command information transmitted in the past, which is data for generating error check values, and one or more control commands or control command information output from the storage unit; The error check value may be generated using the control command to be transmitted this time output from the control command output unit.

  As described above, the gaming machine of the present invention can generate an error check value including a control command transmitted this time in addition to a control command transmitted in the past or a control command transmitted in the past and its error check value. However, from the viewpoint of improving the security strength, it is preferable to generate the error check value of the control command transmitted this time without using the control command itself transmitted this time. Specifically, it is preferable to generate an error check value to be added to the control command to be transmitted this time using a control command transmitted in the past or a control command transmitted in the past and its error check value. As described above, when the error check value is generated without using the control command transmitted this time, there is no relationship between the control command transmitted this time and the error check value added thereto. For this reason, even if an unauthorized person obtains two values, that is, a control command and an error check value added to the control command, the relationship between them cannot be analyzed. Therefore, it can be made more difficult for an unauthorized person to analyze the relationship between the control command and the error check value added thereto. That is, even if an unauthorized person obtains control command information, it is possible to make it more difficult to perform an unauthorized act.

  In the above embodiment, the main control unit 110 adds a predetermined initial value to the control command and transmits it, and the effect control unit 203 similarly performs authentication using the predetermined initial value. The invention is not limited to this, and the authentication process may not be performed for the control command to which the initial value is added. For example, when generating an error check value to be added to the control command to be transmitted this time using the control command information transmitted n times before, the effect control unit 203 is initial for the control command information received from the 1st to nth. Assuming that a value is added, the authentication process may be performed from the control command information received at the (n + 1) th time without performing the authentication process.

  In addition, the main control unit 110 may be provided with time measuring means, or the time measuring information acquired from the time measuring means at the control command transmission timing may be used as the initial value using the time measuring means provided in the main control unit 110 in advance. As a result, the error check value can be made a value peculiar to the state of the gaming machine 1, and even if an unauthorized person who does not know the initial value value acquires some control command information, the error check value is not analyzed. The security strength can be further improved. In this case, as described above, the authentication process may not be performed for the control command to which the initial value is added. In addition, in the case where time information is added as an initial value to two or more control commands, the effect control unit 203 maintains time continuity between time information transmitted continuously as an initial value. That is, the authentication process may be performed by referring to whether or not the value of time information transmitted continuously increases in accordance with the transmission order.

  In this way, in the present invention, time information may be included in the unique information used as the initial value. In other words, the unique information is information unique to the gaming machine 1 that acquires the initial value at the transmission timing of the control command. As the timing information, timing information unique to the gaming machine 1 measured by the timing means of the main control unit 110 after the gaming machine 1 is turned on may be used, or absolute time information may be used. Good. By using timekeeping information unique to the gaming machine 1, the confidentiality of the initial value can be increased, and the security strength can be further improved.

  When initial values are added to a plurality of control commands, the initial values may be fixed values or variable values. For example, when identification information is used as an initial value, different identification information may be used for each control command, or the same identification information may be used. In addition, when using timekeeping information as an initial value, the timekeeping information obtained from the timekeeping means may be used for each transmission timing of the control command, or the timekeeping information obtained at the transmission timing of the control command to be transmitted first may be controlled by a plurality of controls. It may be used as an initial value for a command.

  In the above embodiment, the main control unit 110 and the effect control unit 120 realize the authentication function by software using the CPU, ROM, and RAM. However, the present invention is not limited to this, and generates an error check value. An authentication function may be realized by hardware by providing a generation circuit for the above, an inspection circuit for performing error inspection, and the like.

  Moreover, although the example which applies this invention to a pachinko game machine was shown in the said embodiment, it is not limited to this, This invention is a ball game machine other than pachinko game machines, such as a sparrow ball game machine and an arrangement ball. It can also be applied to other gaming machines such as slot machines such as slot machines. Also in these gaming machines, the same effects as in the above embodiment can be obtained by configuring in the same manner as in the above embodiment. Moreover, the said embodiment can divert each other's technique as long as there is no contradiction or a problem in particular in the objective, a structure, etc.
