  In the present embodiment, the sub-control unit 91 mounted on the effect control board 90 performs output control of effect devices such as the liquid crystal display 51, effect effect LEDs 52, speakers 53 and 54, and reel LEDs 55. However, in addition to the sub-control unit 91, an output control unit that directly controls the output of the effect device is mounted on the effect control board 90 or another board, and the sub-control unit 91 is based on a command from the main control unit 41. The output control unit may determine the output pattern of the effect device, and the output control unit may control the output of the effect device based on the output pattern determined by the sub control unit 91. In such a configuration, the sub control unit 91 and the output control may be performed. The output control of the rendering device is performed by both of the units.

  Further, in the present embodiment, the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, and the reel LED 55 are exemplified as the effect device, but the effect device is not limited to these, for example, a mechanically driven display. A device or a mechanically driven item may be applied as the effect device.

  The effect control board 90 includes a sub-control unit 91, a display control circuit 92, an LED drive circuit 93, an audio output circuit 94, a reset circuit 95, a switch detection circuit 96, an RTC 97, and a power interruption detection circuit 98. .

  Similar to the main control unit 41, the sub control unit 91 is configured by a microcomputer including a sub CPU 91a, a RAM 91b, a ROM 91c, and an I / O 91d, and controls production. The display control circuit 92 performs display control of the liquid crystal display 51 connected to the effect control board 90. The LED drive circuit 93 performs drive control of the effect LED 52 and the reel LED 55. The audio output circuit 94 performs audio output control from the speakers 53 and 54. The reset circuit 95 sends a reset signal to the sub CPU 91a when the power is turned on or when an initialization command from the sub CPU 91a is not input for a certain period of time. The switch detection circuit 96 detects a detection signal input from the effect switch 56 connected to the effect control board 90. The RTC 97 is a device having the same function as the RTC 50. The power interruption detection circuit 98 monitors the power supply voltage supplied to the slot machine 1 and, when detecting a voltage drop, outputs a voltage drop signal indicating that to the sub CPU 91a.

  The sub CPU 91a receives various commands for performing an effect upon receiving a command transmitted from the game control board 40, and directly or indirectly controls each part of the control circuit mounted on the effect control board 90. . Similar to the main CPU 41a, the sub CPU 91a has an interrupt function (including an interrupt prohibition function). One of the interrupt terminals of the sub control unit 91 is connected to a strobe (INT) signal line that is output when the main control unit 41 transmits a command, among the command transmission lines, and the sub CPU 91a receives the strobe signal. An interrupt is generated based on the input to acquire a command from the main control unit 41 and execute a command reception interrupt process to be stored in the buffer. Further, the sub CPU 91a executes an interrupt process (sub), which will be described later, by generating an interrupt every time the number of clock inputs reaches a certain number, that is, every certain interval. One of the interrupt terminals of the sub-control unit 91 is connected to the power interruption detection circuit 98, and the sub CPU 91a responds to the input of the voltage drop signal output from the power interruption detection circuit 98. Execute processing (sub). Also, when an unused interrupt occurs in the sub CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and the data stored in the RAM 91b is held while the backup power is supplied.

[Judgment processing of storage means]
Further, in the sub CPU 91a, legitimate information (for example, programs, setting values, data, etc.) is stored in the ROM 91c when the power is turned on, and an illegal act (for example, a difference between the ROM 91c and the ROM in which the illegal program is written) is stored. A determination process is performed to determine that an action to change is not performed. This determination process is particularly applied to the program area of the ROM 91c, but of course, it can also be applied to areas such as image data, audio data, and setting data stored in the ROM 91c. The description will be made without limiting the area.

  In this determination process, the checksum value calculated from the information stored in the ROM 91c matches the checksum value calculated from the legitimate information (for example, ROM information stored by the gaming machine manufacturer). It is determined by whether or not it exists. Here, the checksum is a value obtained by summing information (for example, hexadecimal numbers) in the storage area to be calculated. However, if the checksum value is calculated for the entire storage area of the ROM 91c, the result of the calculation is the same every time. Therefore, the incorrect value is stored in the ROM 91c and the checksum value is the same. It is easy to adjust so. Therefore, it is determined whether the checksum value calculated from the information stored in the ROM 91c matches the checksum value calculated from the regular information (that is, the checksum value in the regular ROM). Alone, it cannot be determined that an illegal act is not performed on the ROM 91c.

  Therefore, the sub CPU 91a changes the storage area to be calculated for the checksum value based on the timing information of the RTC 97. Specifically, FIG. 5 is a schematic diagram for explaining a process of calculating a checksum value as a determination value based on the time information of the RTC 97 and outputting the determination value. Note that the RTC 97 timekeeping information and determination value shown in FIG. 5 are all displayed in hexadecimal. First, the RTC 97 outputs “month” and “day” information to the sub CPU 91a by a time measuring operation. In the example on the left side shown in FIG. 5, the sub CPU 91a selects the storage area (the fourth column from the left of the ROM 91c, the fourth line from the top) of the ROM 91c based on the date information “April 1”. I have identified. On the other hand, in the example on the right side illustrated in FIG. 5, the sub CPU 91a performs the calculation target storage area of the ROM 91c (the first column from the right of the ROM 91c and the third line from the top) based on the date information “April 2”. ) Is specified.

  The sub CPU 91a calculates a checksum value for a storage area to be calculated in the ROM 91c (an area enclosed by a square in the ROM 91c in FIG. 5), and outputs the calculation result as a determination value. In the example on the left side shown in FIG. 5, “A012” is output as the determination value of “April 1”. On the other hand, in the example on the right side shown in FIG. 5, “86C5” is output as the determination value of “April 2”. Here, in the sub CPU 91a, the calculation target storage area of the ROM 91c specified based on the date information is determined in advance in a design document or the like, and the checksum value calculated from the regular information corresponding to the date information This is known in advance by the gaming machine manufacturer. Therefore, it can be determined that an illegal act has not been performed on the ROM 91c by comparing the determination value based on the date information with a value that is previously grasped by the gaming machine manufacturer. In addition, since the calculation target storage area of the ROM 91c is changed based on the date information, the calculation result of the checksum becomes a different value every time, and it is difficult to perform an illegal act on the ROM 91c. The checksum value calculated from the legitimate information corresponding to the date information, which is known in advance by the gaming machine manufacturer, is provided to the hall from the gaming machine manufacturer when the slot machine 1 is delivered (for example, as electronic data) (E.g., provided on a paper medium as a data book), it becomes possible to compare checksum values.

  As a method of comparing the determination value based on the date information with a value that is previously grasped by the gaming machine manufacturer, the sub CPU 91a displays the determination value on the display device (for example, the liquid crystal display 51) of the slot machine 1, There is a method in which a store clerk compares the value with a table provided by a gaming machine manufacturer. In this case, if the determination value is displayed as it is on the display device of the slot machine 1, the checksum calculation result is directly displayed, and there is a possibility that the calculation target storage area of the ROM 91c may be specified. Therefore, the sub CPU 91a calculates a determination value using an irreversible function such as a hash function, and displays the determination value after the calculation on the display device of the slot machine 1. Thereby, it is possible to prevent the checksum calculation result from being directly known from the determination value after the calculation.

  Further, as another method of comparing the determination value based on the date information with a value that is previously grasped by the gaming machine manufacturer, the sub CPU 91a transmits the determination value to the management server, and the determination value is preliminarily determined by the management server. There is a method of confirming whether or not it matches the value grasped by the manufacturer. Note that the management server stores in advance in the storage device values that are known by the gaming machine manufacturer. As will be described later, the management server may be a management server 1200 held by a gaming machine manufacturer (provider of the slot machine 1), a hall server provided in the hall where the slot machine 1 is installed, or the like. Good.

  Furthermore, as another method for comparing the determination value based on the date information with a value that is previously grasped by the gaming machine manufacturer, there is a method in which the sub CPU 91a outputs the determination value as a two-dimensional code. When a decision value is included in a two-dimensional code and output, the decision value is read via a portable terminal having a two-dimensional code reading function and an Internet network connection function, and the management server 1200 held by the gaming machine manufacturer or the like. The read judgment value can be confirmed. In particular, when the player confirms whether or not the slot machine 1 is cheating, a menu screen is displayed from a demonstration screen (non-game screen) displayed on the liquid crystal display 51. The determination value is output as a two-dimensional code, and the operation is simply performed by reading the two-dimensional code with a portable terminal and confirming it with the management server 1200 held by the gaming machine manufacturer.

(Modification)
In the above-mentioned sub CPU 91a, since the check sum calculation result does not become the same value every time, the target storage area for calculating the check sum value is changed based on the timing information of the RTC 97. However, the configuration that prevents the checksum calculation result from being the same value every time is not limited to the configuration that changes the storage area that is the target of calculating the checksum value. For example, the sub CPU 91a may change the calculation method of the determination value based on the time information of the RTC 97 instead of the checksum. Specifically, FIG. 6 is a schematic diagram for explaining a modification example of the process of calculating the determination value based on the time information of the RTC 97 and outputting the determination value. Note that the RTC 97 timing information and determination value shown in FIG. 6 are all displayed in hexadecimal. First, the RTC 97 outputs “month” and “day” information to the sub CPU 91a by a time measuring operation. In the example on the left side illustrated in FIG. 6, the sub CPU 91a specifies the calculation function a based on the date information “April 1”. Here, as the arithmetic function a, for example, a function that sums the values stored in the odd columns of the storage area of the ROM 91c. On the other hand, in the example on the right side illustrated in FIG. 6, the sub CPU 91 a specifies the calculation function b based on the date information “April 2”. Here, as the calculation function b, for example, it is assumed that the function stores the values stored in the even rows of the storage area of the ROM 91c.

  The sub CPU 91a calculates and outputs a determination value for the storage area of the ROM 91c (all areas of the ROM 91c in FIG. 6) using an arithmetic function specified by date information. In the example on the left side illustrated in FIG. 6, the determination value is calculated using the calculation function a, and “B123” is output as the determination value of “April 1”. On the other hand, in the example on the right side shown in FIG. 6, the determination value is calculated using the calculation function b, and “F586” is output as the determination value of “April 2”. Since the determination value based on the date information is compared with the value previously grasped by the gaming machine manufacturer to determine that no illegal act has been performed on the ROM 91c, it is the same as the configuration described above. The description of this process is omitted. Thus, by changing the calculation method of the ROM 91c based on the date information, the calculation result of the determination value can be set to a different value every time.

  As yet another modification, the sub CPU 91a may change information used for calculating the determination value based on the time information of the RTC 97. For example, the sub CPU 91a specifies the upper 4 bits of the information read from the storage area of the ROM 91c as the calculation target based on the date information “April 1”, and sums the specified calculation target information to “April The judgment value of “1 day” is output. Further, the sub CPU 91a identifies the lower 4 bits of the information read from the storage area of the ROM 91c as the calculation target based on the date information “April 2”, and sums the specified calculation target information to “April The judgment value “2 days” is output. In this way, by changing the information used for calculating the determination value based on the date information, the calculation result of the determination value can be set to a different value every time.

  In addition, the calculation of the determination value includes the configuration for changing the storage area to be calculated based on the date information, the configuration for changing the calculation method based on the date information, and the information used for calculating the determination value based on the date information. The configuration may be executed using any one of the configurations to change, or a plurality of configurations may be combined. Here, the determination value may be a value obtained by calculating information read from the storage area of the ROM 91c, or may be the read information itself. That is, in the case of a configuration in which the calculation target storage area is changed based on the date information, for example, the determination value of “April 1” is the information itself in the first row and first column of the ROM 91c, and the determination of “April 2” is performed. The value may be the information itself in the fifth row and first column of the ROM 91c.

  Moreover, although the example which uses date information as time information of RTC97 was demonstrated, it is not limited to this, "Year (year)", "Month", "Day", "Day of the week" time-measured by RTC97 ”,“ Hour ”,“ minute ”,“ second ”, or a combination of a plurality of pieces of information may be used. For example, by using “year (year)”, “month”, and “day” information as time information of the RTC 97, even if the determination value is “April 1”, every “year (year)” Therefore, it becomes difficult to perform illegal acts on the ROM 91c.

  Further, in the above description, the determination process for determining that an illegal act is not performed on the ROM 91c has been described, but the same configuration is applied to the RAM 91b of the sub CPU 91a, the RAM 41b of the main CPU 41a, and the ROM 41c. Can be applied. Here, when the same configuration is applied to the RAM 41b and the ROM 41c of the main CPU 41a, the time information of the RTC 50 is used instead of the RTC 97. Note that when the same configuration is applied to the RAM 91b of the sub CPU 91a and the RAM 41b of the main CPU 41a, the game is particularly applied to the RAM 91b and RAM 41b areas for storing programs and setting values read from the ROM 91c and ROM 41c. It is possible to determine whether or not an illegal program is being executed in the process. Further, even if the determination process is applied to any one of the RAM 91b and ROM 91c of the sub CPU 91a and the RAM 41b and ROM 41c of the main CPU 41a, the determination process is applied to all or a part of the plurality of storage means. May be.

  Specifically, the case where the main CPU 41a generates the determination value of the ROM 41c will be described as an example. First, the target storage area for calculating the checksum value is changed based on the timing information of the RTC 50. Next, the main CPU 41a calculates a checksum value for the calculation target storage area of the ROM 41c, and outputs a command that can specify the calculation result as a determination value to the sub CPU 91a. The sub CPU 91 a specifies a determination value from the received command, calculates the specified determination value using an irreversible function such as a hash function, and displays the determination value after the calculation on the liquid crystal display 51 of the slot machine 1. Of course, even the determination value of the ROM 41c may be generated not by the main CPU 41a but by the sub CPU 91a. That is, the value of the storage area to be calculated in the ROM 41c specified based on the timing information of the RTC 50 may be output to the sub CPU 91a as an identifiable command, and the sub CPU 91a may generate the determination value of the ROM 41c using the value. . In addition, the value stored in the ROM 41c is output to the RAM 91b of the sub CPU 91a when the power is turned on, and the determination value is stored in the storage area of the RAM 91b in which the value of the ROM 41c is stored based on the timing information of the RTC 97. It may be generated.

  Further, in the present embodiment, the RTC 50 is provided on the main CPU 41a side and the RTC 97 is provided on the sub CPU 91a side. However, even when no RTC is provided on the sub CPU 91a side, the RTC 50 timing information can be specified as a command. The data may be output to the sub CPU 91a, and the sub CPU 91a may generate the determination value of the ROM 91c based on the time measurement information.

[About database in RAM 91b]
Next, a database constructed in the RAM 91 of the slot machine 1 will be described. Hereinafter, the database may be referred to as “DB”. In this embodiment, there are a game history database and an occurrence information database as databases in the RAM 91. A database in the RAM 91b will be described with reference to FIG. FIG. 10 shows a RAM database. FIGS. 10A and 10B show an example of a game history database and an occurrence information database, respectively. In the present embodiment, a period from when the game is started until when the game is ended by digesting the number of games of 1 or more is referred to as a “game history update period”. The game history update period is a period during which the game history database in the RAM 91b can be updated. “Starting a game” means that a player inputs a password for starting a game. The password is used for starting recording of a game history in accordance with the progress of the game or for taking over the game history of the previous game. Note that the game can be started without entering the password, but the game history is not stored in the slot machine 1. “End game” means that the player selects “End” or “Create two-dimensional code” on the menu screen displayed on the liquid crystal display 51. “End” means to end the game without generating a two-dimensional code.

  First, the game history database will be described. In this embodiment, as shown in FIG. 10A, the game history database includes terminal identification information (SIM data) that can identify the mobile terminal 1100 owned by the player, and the total number of games in the game history update period. BB count, RB count, the current level of the character that the player virtually holds in the game, and the experience value (fractional) acquired by the player. In the present embodiment, the sub CPU 91a gives an experience value on the condition that a predetermined achievement condition is satisfied when a player inputs a password at the start of the game, and acquires 10 experience values. The character level is added each time. Each time the level value of the character exceeds a certain value, the number of types of effects that can be executed is increased.

  Further, the number of games in the game history database is incremented and updated by one each time one game is consumed within the game history update period. Each time BB or RB is won within the game history update period, the number of BBs and the number of RBs in the game history database are updated. Each time the character level is added within the game history update period, the level of the game history database is updated. Each time an experience value is acquired within the game history update period, the experience value in the game history database is increased and updated. These incremental updates may be updated together when the game history update period ends.

  Next, the occurrence information database will be described. In the present embodiment, the occurrence information is information that can identify an event that has occurred in the slot machine 1. In the present embodiment, the occurrence information includes error information, door opening information, and connector disconnection information.

[Error information]
The error information is information that can identify an error that has occurred in the slot machine 1. The errors of the slot machine 1 of the present embodiment are a RAM error error, a communication error, a setting value error, a reel rotation error, a throwing error, a hopper paying error, a paying medal clogging error, a throwing medal clogging error, a throwing medal dead error, and a full tank error. , Including door opening error.

  First, a RAM abnormality error will be described. In the slot machine 1 of the present embodiment, when the CPU 41a of the main control unit 41 detects a voltage drop signal, a power interruption interrupt process is executed. In the power interruption interrupt processing, the register is saved in the stack of the RAM 41b, and the destructive diagnosis data in which any bit is 1 in the RAM 41b of the main control unit 41, that is, specific data other than 0 is stored. The RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all the areas becomes 0, and stored in the RAM 41b. The RAM parity is a value calculated as an exclusive OR of values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 41b. For this reason, if the RAM parity based on the data stored in all areas of the RAM 41b is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 41b is 1. In this case, the RAM parity adjustment data is 1.

  The CPU 41a calculates the RAM parity based on the data stored in all areas of the RAM 41b at the time of activation, confirms the value of the destructive diagnosis data, the RAM parity is 0, and the destructive diagnosis On the condition that the data value is also correct, the processing state of the CPU 41a is restored to the state before power interruption based on the data stored in the RAM 41b. However, when the RAM parity is not 0 (in the case of 1) or for destructive diagnosis If the data value is not correct, it is determined that the RAM is abnormal and the progress of the game is disabled. Unlike the other error states, the RAM abnormality error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the setting change state described above. It is released when Further, errors other than the RA abnormality error are canceled by operating the reset switch 23 or the reset / setting switch 38. The RAM abnormality error is also an error that occurs when the power switch 39 is turned on in a state where no information is stored in the RAM 41b. That is, a RAM abnormality error also occurs when the power is first turned on.

  Next, communication errors will be described. When the sub-control unit 91 acquires the game counter 1 command, the sub-control unit 91 stores the first game counter value specified from the game counter 1 command in the game counter value storage area 1 assigned to the RAM 91b. Further, when the sub-control unit 91 acquires the game counter 2 command, the sub-control unit 91 stores the second game counter value specified from the game counter 2 command in the game counter value storage area 2 assigned to the RAM 91b. When the second game counter value is stored, the sub-control unit 91 determines whether or not the second game count value matches the first game count value stored in the game counter value storage area 1.

  In this determination, the game counter value storage area 1 should store the first game counter value specified from the game counter 1 command transmitted at the start of the current game. Since the value of the game counter is incremented by 1 before the start of the game and is not updated again during the game, the game counter 1 command specified at the start of the current game is specified. The 1 game counter value and the 2nd game counter value specified from the game counter 2 command newly received this time should be the same. If the sub-control unit 91 determines that the first game counter value and the second game counter value are different values, it is determined that the main control unit 41 and the sub-control unit 91 cannot communicate properly. It is determined that a communication error has occurred.

  The set value error is an error that is determined when the set value is not an appropriate value (for example, when the set value is a value other than 1 to 6). The reel rotation error is an error determined when the reel reference position is not detected by the reel sensor 33 for a certain period or longer. The insertion error is an error that is determined when the insertion of a medal is detected outside the period during which the insertion of a medal is permitted. The hopper payout error is an error that is determined when the payout sensor 34c detects a payout abnormality due to an illegal act to the hopper tank 34a. The payout medal clogging error is an error determined when it is detected that the payout medal in the hopper tank 34a is clogged. The inserted medal clogging error is an error determined when it is detected that the medal inserted from the medal insertion unit 4 is clogged.

The full tank error is an error determined when the full tank sensor 35a detects that the overflow tank 35 is full. The door opening error is an error that is determined when the front door 1b is opened.

  Further, when the main control unit 41 detects that an error (for example, a RAM abnormality error) that can identify that the main control unit 41 has occurred, an error command for the generated error is sent to the sub-control unit 91. To send. The sub-control unit 91 analyzes the error command and updates the error information in the occurrence information database in the RAM 91b so that the date and time when the error occurs can be specified. Further, when the sub control unit 91 detects that an error that can specify that the sub control unit 91 has occurred (for example, a communication error), the sub control unit 91 can specify the date and time when the error occurred. The error information in the occurrence information database in the RAM 91b is updated so that

[About database in storage unit 220]
Next, a database constructed in the storage unit 220 of the management server 1200 will be described. In the present embodiment, the database of the storage unit 220 includes a player database, a game history database, and an occurrence information database. The database according to the present embodiment will be described with reference to FIG. FIG. 11 is a diagram illustrating a database in the storage unit. 11A to 11C show examples of a player database, a game history database, and an occurrence information database, respectively.

  As shown in FIG. 11A, in the player database, terminal identification information (SIM data) that can identify the portable terminal 1100 owned by the player, current status (standby / game), password (last ), The total number of games up to now, the total number of BBs, the total number of RBs, the current level of characters virtually owned by the player in the game, and the experience value obtained by the player (fractional) Is registered for each player (for each terminal identification information). In addition to this, the player information includes the player name (registered name), gender, date of birth, personal information (member information) of the player such as prefectures, although not shown. . In the present embodiment, the sub CPU 91a gives an experience value on the condition that a predetermined achievement condition is satisfied when a password is input by the player at the start of the game, and acquires 10 experience values each time. Is added to the character level. Each time the level value of the character exceeds a certain value, the number of types of effects that can be executed is increased.

  As shown in FIG. 11B, the game history database includes terminal identification information (SIM data) that can identify the portable terminal 1100 owned by the player who played the game, the game date and time, and the slot machine 1 at the start of the game. , The game random number randomly acquired by the slot machine 1 at the end of the game, the number of games in the game, the number of BBs in the game, the number of RBs in the game, the end of the game Game history information including a level value at the time, an experience value (of fraction) at the end of the game, and the like is registered.

  As shown in FIG. 11C, occurrence information (error information, door opening information, connector disconnection information) is registered for each slot machine identification information (ID) in the occurrence information database. The slot machine identification information (ID) is information added to one slot machine and is information for identifying the one slot machine. Each occurrence information can be stored up to a predetermined number (three in the example of FIG. 11). The database (game database, game history database, occurrence information database) in the storage unit 220 is updated by the update process. In addition, the generation information to be erased may be stored in another storage area by being updated. The other storage area is, for example, a storage area different from the storage unit 220 or a storage area of an external device connected to the management server 1200.

  In addition, when a predetermined operation is performed on the operation unit 230 by the administrator, an image based on the generated information database (hereinafter referred to as “generated information image”) is displayed in a manner that is visible to the administrator. It can be displayed on the part 240. By viewing the generated information image, the administrator can grasp the history of each slot machine error status, door opening status, and connector disconnection status. Further, for example, in the example of FIG. 11C, as shown in the “door opening information” column, it is a short period of February 16 to 21, 2014, and at the time of power interruption (midnight). The opening of the front door 1b and the disconnection of the connector are each detected three times. Therefore, the administrator can infer that an unauthorized person enters the amusement store in the middle of the night and is cheating. The administrator said, “It is a short period of February 16 to 21, 2014, and when the power is cut off (midnight), the opening of the front door 1b and the disconnection of the connector are detected three times respectively. It is possible to convey to the person in charge of the amusement store or the like by a predetermined transmission means (telephone or e-mail, etc.).

  In addition, when the slot machine 1 is brought in at 10:00 AM on February 1, 2012, for example, a connector generated on the date and time before the carry-in date (for example, 11:00 AM on January 15, 2012) A case where connector disconnection information indicating that disconnection has occurred is stored in the storage unit 220 will be described. In such a case, the administrator can specify that the connector is disconnected within the carry-in period. Therefore, the manager can inform the manager of the amusement store that the connector disconnection has occurred within the carry-in period.

[Processing flow of gaming system 1001]
Next, a processing flow of the gaming system 1001 will be described.

  First, the sub-control unit 91 of the slot machine 1 checks whether or not the date has been changed. Here, a method for confirming whether or not the date has been changed will be described. When energized, it is only necessary to detect whether or not the date of the sub-control unit 91 has been changed based on the timing result of the RTC 97. When it is determined that the date has been changed, the sub-control unit 91 deletes the game history information and other information while leaving the generated information stored in the RAM 91b. In addition, since the generated information and the game history information and other information are stored in a different area in the storage area of the RAM 91b, the generated information can remain and the game history information can be erased. When it is determined that the date has not been changed, the main control unit 41 determines whether or not the setting is changed.

  When it is determined that the setting is changed, the sub-control unit 91 of the slot machine 1 generates a first two-dimensional code. In the first two-dimensional code, the URL (update URL) indicating the location of the update page on the management server 1200, the “setting change operation flag for specifying the setting change state”, and the first Slot machine identification information of the slot machine 1 that generates the two-dimensional code, a password input at the start of the game, and a game random number that is a random value acquired every time the first two-dimensional code is created (in this embodiment, (32-bit random number), game history information corresponding to the terminal identification information of the player, and "occurrence information". The sub-control unit 91 may generate the first two-dimensional code by including the above-described determination value information in addition to the game history information and the occurrence information in the first two-dimensional code. The game history information is each piece of information (total number of games, number of BBs, number of RBs, level value, experience value) constituting a game history database (see FIG. 10A) of the RAM 91b. Hereinafter, the information that has been subjected to the URL encoding process is referred to as “encrypted information”.

  Further, the sub-control unit 91 ends the display of the first two-dimensional code and erases the game history information when the end condition is satisfied. Here, the end condition is a first condition that is satisfied when a predetermined time (for example, 20 seconds) elapses, a second condition that is satisfied when a two-dimensional code end operation is performed, and a game progress operation ( For example, it includes a third condition that is established when a medal is inserted. The reason for deleting the game history information is that the game history information is output as a two-dimensional code, so that it is not necessary to remain in the RAM 91b, and the storage efficiency of the RAM 91b is improved.

  Even when it is determined that the setting is not changed, the sub-control unit 91 detects that the player has performed a two-dimensional code generation operation for generating and displaying a two-dimensional code. Generates and displays a second two-dimensional code. The second two-dimensional code to be generated includes a URL (update URL) indicating the location of the update page on the management server 1200, and the “of the slot machine 1 that generates the second two-dimensional code subjected to the URL encoding process. Slot machine identification information, a password input at the start of the game, a game random number (32-bit random number in this embodiment) that is a random value acquired every time the second two-dimensional code is created, and the player's It is generated from the game history information corresponding to the terminal identification information and the occurrence information. However, the generated second two-dimensional code does not have a setting change operation flag. The sub-control unit 91 may generate the second two-dimensional code by including the above-described determination value information in addition to the game history information and the occurrence information in the second two-dimensional code. When the end condition is satisfied, the sub control unit 91 ends the display of the second two-dimensional code and deletes the game history information and the occurrence information.

  Further, in order to control to the setting change state, the front door 1b is opened regardless of whether the slot machine 1 is manufactured or in a playable state, and the setting key switch 37 (FIG. 2). Must be turned ON. Therefore, the control to the setting change state can be basically performed by the store clerk of the game store, but cannot be performed by the player. That is, the first two-dimensional code is generated by the store clerk performing an operation for shifting to the setting change state.

  It should be noted that the setting change state may be entered on condition that “power ON” + “setting key switch ON” + “front door opening detection”. Thereby, an unauthorized setting change in a state where the front door is not opened can be prevented. Once the setting change state is entered, the setting change state is maintained regardless of the open / closed state of the front door until the end condition (setting key switch is turned OFF after setting value is established) is satisfied. You may make it do. As a result, even if the front door is closed during the setting change state, the setting change state is not terminated, so that it is possible to prevent the trouble of shifting to the setting change state again.

  In addition, the setting confirmation state can be shifted by setting the setting key switch to ON. However, the setting confirmation state is not limited to this, and the setting confirmation state is set on condition that the setting key switch is ON and the front door opening is detected. You may make it transfer to. Thereby, unauthorized setting confirmation in the state where the front door is not opened can be prevented. Once the setting confirmation state has been entered, the setting confirmation state is maintained regardless of whether the front door is open or closed until an end condition (setting key switch is turned OFF) for ending the setting confirmation state is satisfied. Also good. Thereby, even if the front door is closed during the setting confirmation state, the setting confirmation state is not terminated, and therefore it is possible to prevent the trouble of shifting to the setting confirmation state again.

  On the other hand, the two-dimensional code generation operation is performed by a player, but is not usually performed by a store clerk. That is, when the player performs a two-dimensional code generation operation, the second two-dimensional code is generated.

  If the player has played a game, but the game is terminated without performing the two-dimensional code generation operation, the second two-dimensional code generation process is not performed, so the portable terminal held by the player The game history information corresponding to 1100 remains. Such remaining game history information is deleted.

  Next, when the management server 1200 receives the encrypted information obtained by reading the two-dimensional code with the portable terminal 1100, the management server 1200 executes an update process. The control unit 210 determines whether or not the terminal identification information (SIM data) of the mobile terminal 1100 that is the transmission source of the update request is already registered in the player database, and the terminal identification information is already registered in the player database. If it is, it is determined that the URL is not registered in the illegal URL DB, and URL decoding processing is executed on the URL of the update request. By the URL decoding process, each parameter (password, game random number, game history information, generation information) that is encrypted information can be acquired.

  Next, the control unit 210 determines whether or not the same password or game random number specified from the update request is stored in the game history information corresponding to the terminal identification information in the game history database. As a result, when neither the same password nor the game random number is stored in the game result information, the control unit 210 determines that the player in the player database is based on the game history information received from the mobile terminal 1100. The content of the player information corresponding to is updated, and the game history information is additionally registered in the game history database. Also, the status of the player information is updated during standby. Further, the control unit 210 updates the generation information corresponding to the slot machine identification information in the generation information database (see FIG. 11C) based on the generation information received from the mobile terminal 1100. Next, the control unit 210 registers the URL of the update request in the registration URL DB.

  When the update process of the management server 1200 is completed, the control unit 210 determines whether or not the two-dimensional code captured by the mobile terminal 1100 is the first two-dimensional code. This determination is made by detecting the presence / absence of a setting change operation flag. If it is determined that the setting change operation flag is included as a result of the URL decoding process, the analyzed two-dimensional code is determined to be the first two-dimensional code. On the other hand, if it is determined that the setting change operation flag is not included as a result of the URL decoding process, the analyzed two-dimensional code is determined to be the second two-dimensional code.

  When it is determined that the captured two-dimensional code is the first two-dimensional code, the communication unit 250 acquires the possibility of fraud (door opening information and connector disconnection information) from the generated information through the update process. It transmits with respect to the portable terminal 1100 specified from portable terminal identification information. That is, the fraud possibility information can be transmitted to the mobile terminal of the clerk who is controlled to the setting change state. The control unit 110 of the portable terminal 1100 causes the display unit 140 to display an image based on information transmitted from the management server 1200. The display unit 140 displays, for example, “Door opening occurrence: May 17, 2014 AM1: 13 (at power interruption) Connector disconnection occurrence: none”. A viewer who has viewed the display unit 140 (that is, a store clerk who has shifted to the setting change state) can recognize the occurrence date and time of occurrence of door opening and that no connector disconnection has occurred.

  When it is determined that the captured two-dimensional code is not the first two-dimensional code (the second two-dimensional code), the communication unit 250 corresponds to the terminal identification information acquired by the update process of the management server 1200. The game history information to be transmitted is transmitted to the portable terminal 1100 specified from the terminal identification information. That is, the game history information can be transmitted to the portable terminal of the player who has performed the two-dimensional code generation operation. The control unit 110 of the portable terminal 1100 causes the display unit 140 to display an image based on the game history information. A viewer (player) who has viewed the display unit 140 can recognize his / her game history information.

Next, main effects obtained by the embodiment described above will be described.
(1) In this embodiment, the storage area to be calculated in the ROM 91c is specified based on the date information of the RTC 97, and the checksum value (determination) is determined using the information stored in the specified storage area to be calculated. Information). Therefore, the calculation result becomes a different value every time. Therefore, in the present embodiment, since a different checksum value can be generated based on the RTC 97, an illegal act on the ROM 91c can be easily found.

  (2) In the present embodiment, whether or not the determination value displayed by the store clerk is calculated from legitimate information by displaying the determination value (for example, the checksum value) on the liquid crystal display 51 or the like. Can be confirmed and fraudulent acts on the ROM 91c can be determined.

  (3) In this embodiment, since the determination value can be displayed during non-game from the menu screen displayed on the liquid crystal display 51, the player himself / herself can confirm the presence / absence of an illegal act against the ROM 91c.

  (4) In the present embodiment, determination is made based on whether or not the main CPU 41a matches the calculation value calculated from the determination value and the regular information, and the determination result is notified from the liquid crystal display 51, the speakers 53, 54, and the like. As a result, it is possible to confirm whether or not there is an illegal act on the ROM 91c.

  (5) In this embodiment, by specifying the storage area to be calculated based on the date information, the calculation is calculated from regular information by complicating the configuration so that the calculation result has a different value each time. It is possible to prevent fraudulent acts on the ROM 91c to be the result.

  (6) In this embodiment, by specifying the calculation function based on the date information, the calculation result is calculated from the regular information by making the configuration complicated so that the calculation result becomes a different value every time. It is possible to prevent illegal acts on the ROM 91c.

  (7) In this embodiment, when a player performs a two-dimensional code generation operation (an operation for a player to generate and display a two-dimensional code) at the end of the game history update period, the game history update period A second two-dimensional code including game history information about is displayed. The game history information in the management server 1200 can be updated by transmitting the game history information to the management server 1200 by imaging the second two-dimensional code by the portable terminal of the player (management server 1200). 1200 update processing). Here, the second two-dimensional code of the present embodiment includes not only game history information but also occurrence information. Therefore, not only the game history information in the management server 1200 but also the generated information can be updated by imaging the two-dimensional code by the portable terminal of the player. That is, the occurrence information in the management server 1200 is updated by transmitting the occurrence information to the management server 1200 by using the “two-dimensional code imaging action performed for updating the game history information” by the player. Can do.

[Modification]
Although the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to these embodiments. The present invention is not limited to the above-described embodiments, and various modifications and applications are possible. Hereinafter, modifications and the like applicable to the present invention will be described. Further, at least two of the technical items described in the present embodiment described above and the technical items described in the following modifications may be implemented in combination, and the technical items described in the above-described embodiment. May be implemented by replacing the technical matters described in the following modified example, or the technical items described in the following modified examples may be further combined with the replacement. .

  (1) In the present embodiment, it has been described that the storage area to be calculated in the ROM 91c is specified based on the date information. However, when the storage area to be specified is regularly determined in order of date. The storage area to be calculated may be determined not limited to regular but randomly. In addition, the date information is not directly used as information for specifying the storage area to be calculated, but the result of calculating with some function (for example, a function that takes the product of the number of months and the number of days). May be used.

  (2) In the present embodiment, it has been described that a determination value, which is a calculation result (for example, a checksum value) of information stored in a storage area to be calculated in the ROM 91c, is output as a two-dimensional code. The determination value may be included in the first two-dimensional code or the second two-dimensional code including the slot machine identification information and the game history information. As a result, when the first two-dimensional code or the second two-dimensional code is transmitted to the management server 1200, the management server 1200 is a value calculated from regular information that is determined in advance by the gaming machine manufacturer. It can be determined that fraudulent acts are not performed on the ROM 91c.

  (3) Although the slot machine 1 has been described in the present embodiment, the above-described determination processing configuration can be applied in place of a pachinko gaming machine. Specifically, in the pachinko gaming machine, the configuration of the determination process is applied to a ROM that stores a game control program and fixed data mounted on the main board, and a RAM that provides a work area for game control. Alternatively, the configuration of the determination process may be applied to a ROM that stores a program for effect control, fixed data, and the like, and a RAM that provides a work area for the CPU for effect control.

  (4) In the present embodiment, it has been described that the storage area to be calculated in the ROM 91c is specified based on the date information timed by the RTC 97. However, information other than the information timed by the RTC is specified as information for specifying the storage area to be calculated. It may be the information. Specifically, the storage area to be calculated may be specified based on information such as the number of games stored in the game history database (see FIG. 10A) of the RAM 91b. In this case, it is assumed that a value calculated from regular information is also generated in advance corresponding to information such as the number of games (for example, the number of games is 10). Furthermore, the storage area to be calculated may be specified based on information such as a password stored in the player database (FIG. 11A) of the storage unit 220. In this case, it is assumed that the value calculated from the regular information is also generated in advance corresponding to the player information (for example, registration number 15) specified by the password.

  (5) In the present embodiment, the determination value is compared with a value calculated from legitimate information determined in advance by the gaming machine manufacturer, and it is determined that an illegal act is not performed on the ROM 91c. Although it has been described that it can be performed, it can also be determined that a defect (for example, a part of the memory cell is damaged, reading failure from the memory cell, etc.) has not occurred in the ROM 91c.

  (6) In the present embodiment, the configuration in which the sub CPU 91a generates a determination value as to whether or not the legitimate information is stored in the ROM 91c when the power is turned on has been described. The determination value may be generated by. For example, even if the sub CPU 91a generates the determination value at a constant interval (such as once per hour), the sub CPU 91a performs the corresponding operation according to the timing when the store clerk or the player requests display of the determination value from the menu screen during non-game. A determination value may be generated.

  (7) Further, in the present embodiment, it has been described that the occurrence information includes fraud possibility information that can specify that there is a “possibility of fraud”. However, “fault identification information” that can identify “fraud” may be included in the occurrence information. For example, the slot machine 1 is provided with detection means that can open the front door 1b after inserting a specific key held by a store clerk into the keyhole and can detect that the specific key has been inserted. May be. A detection signal indicating the detection result of the detection means is transmitted to the main control unit 41. In the case of such a configuration, “fraud” can be specified as follows. For example, when the front door 1b is opened by inserting a key different from the specific key (for example, a key forged by an unauthorized person) into the keyhole, the result of the detection means is “a specific key has been inserted”. The result is different from the result. The main control unit 41 specifies that an illegal act has been performed by receiving a detection signal indicating a result different from the “specific key inserted” result. When the main control unit 41 specifies that the cheating has been performed, the main control unit 41 transmits a command indicating that the cheating has been performed to the sub-control unit 91. The sub-control unit 91 stores the fraud identification information in the RAM 91b in such a manner that the fraudulent act can be identified and the date and time when the fraudulent act was performed.

  (8) In the present embodiment, the slot machine 1 has been described as displaying a two-dimensional code as an acquisition method for causing the portable terminal 1100 to acquire a determination value, game history information, and occurrence information. However, the acquisition method may be another method. For example, the information to be displayed may be displayed in another form instead of the two-dimensional code. For example, the slot machine 1 may output a sound (sound wave) including a determination value, game history information, and occurrence information from the speakers 53 and 54. In this case, the mobile terminal 1100 may acquire the determination value, the game history information, and the occurrence information by collecting and analyzing the output sound (sound wave).

  As another acquisition method, the slot machine 1 includes a communication unit capable of communicating with the mobile terminal 1100, and the slot machine 1 transmits a determination value, game history information, and occurrence information to the mobile terminal 1100. It may be. Further, when a player or a store clerk connects the slot machine 1 and the portable terminal 1100 with a wire, the slot machine 1 transmits the determination value, the game history information, and the occurrence information to the portable terminal 1100. May be.

  (9) In the gaming system 1001 of the present embodiment, the slot machine 1 performs a URL encoding process as an encryption process on the determination value, occurrence information, game history information, etc., thereby generating a two-dimensional code and performing a decryption process. It has been described that the management server 1200 performs URL decoding processing on the two-dimensional code. However, the encryption process and the decryption process are not limited to the URL encode process and the URL decode process, and other methods may be used. Further, the decoding process may be performed by the mobile terminal 1100 instead of being performed by the management server 1200. In this case, the mobile terminal 1100 performs a decryption process on the encrypted information (determination value, occurrence information, and game history information). The portable terminal 1100 transmits the determination value, the occurrence information, and the game history information on which the decryption process has been performed to the management server 1200. Even with such a configuration, the same effects as the gaming system 1001 of the present embodiment can be obtained.

  (10) As the present embodiment, the slot machine that pays out game media to the player's hand according to the occurrence of a win has been described. However, the game media is enclosed and the game media is handed to the player's hand according to the occurrence of a win. An enclosing slot machine that adds game points (scores) without paying out may be adopted. The base and the drum can be distributed, and the chassis is common and only the base or the base and the drum is called a gaming machine.

  (11) Further, in the pachinko gaming machine, a pachinko gaming machine that pays out a game medium to a player in response to the occurrence of a prize may be adopted, and the game medium is enclosed and the game is played in response to the occurrence of a prize. A sealed pachinko gaming machine that adds game points (scores) without paying out the medium to the player's hand may be adopted. The enclosed pachinko gaming machine is provided with a circulation path for circulating a plurality of balls, which are examples of gaming media, in the pachinko gaming machine, and is provided with a storage unit for storing game points. In accordance with the game point, the game point is added to the storage unit, the game point is subtracted from the storage unit in response to the ball launching operation, and the game point is added to the storage unit in response to the occurrence of a prize. In addition, the pachinko gaming machine has a configuration in which a game board that forms a game area in which a game ball is driven is attached to a game frame provided with a launching device and a ball payout device. It is also possible to share the basic functions such as and distribute only the game board which is a characteristic configuration of the game. In this case, the game board having the characteristic structure of the game is referred to as a game machine.

  It should be understood that the embodiment disclosed this time is illustrative in all respects and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
