  Further, the display by the credit number display device 105, the game progress display device 116 and the earned number display device 115 is visually recognized through the game panel 151.

  The symbol display variation unit 103 is fixed to the housing 101. As shown in FIG. 2 or 4, the left reel device 170L including the left reel 171L, the middle reel device 170M including the middle reel 171M, And a right reel device 170R including a right reel 171R. Each reel device 170L, 170M, 170R is integrated by an upper fixing plate and a lower fixing plate. Each of the reels 171L, 171M, and 171R has a cylindrical shape and is supported so as to be able to rotate with its central axis as a rotation axis. The left reel 171L, the middle reel 171M, and the right reel 171R are arranged side by side in the horizontal direction so that all the rotation axes thereof are located on the same line extending in the substantially horizontal direction. Each of the left reel 171L, the middle reel 171M, and the right reel 171R can rotate independently of each other.

  Here, the structure of each reel device 170L, 170M, 170R will be described. Since the left reel device 170L, the middle reel device 170M, and the right reel device 170R have substantially the same structure, only the structure of the left reel device 170L will be described in detail. 5 (a) to 5 (c), endless symbol belts 175L, 175M, and 175R are shown in a state of being flattened. 5 (a) to 5 (c), for convenience of explanation, array numbers 1 to 21 are assigned to the left side of each of the design belts 175L, 175M, and 175R for each design.

  The left reel device 170L detects a left reel 171L, a reel driving device including a left stepping motor that rotates the left reel 171L, and a reference point (hereinafter, also referred to as “reel reference point”) fixed to the left reel 171L. And a light blocking plate (sensor cut plate) fixed to the left reel 171L. The position where the light blocking plate is arranged corresponds to the position of the reel reference point.

  The left reel 171L is formed in the center of the reel skeleton with a cage-like reel skeleton having a circular outer periphery, an endless left symbol belt 175L (see FIG. 5A) wound around the outer periphery of the reel skeleton. And a disc-shaped boss reinforcing plate attached to the boss portion by screws or the like. On the surface of the left symbol belt 175L, which is the outer peripheral surface of the left reel 171L, as shown in FIG. 5A, a plurality of types of symbols as identification information are printed (for example, 21 in this embodiment). Are drawn). The left symbol belt 175L is maintained endlessly wound around the reel skeleton by affixing a pair of seal portions formed along the longitudinal direction on the left and right sides to the reel skeleton. The types of symbols and the like will be separately described in detail with reference to FIGS. 5 (a) to 5 (c).

  The left stepping motor that rotationally drives the left reel 171L is attached to the support plate with screws or the like so that the rotation axis thereof is in the horizontal direction. The rotation shaft of the left stepping motor is connected to the boss reinforcing plate, and the left reel rotates in conjunction with the rotation of the rotation shaft of the left stepping motor. As a result, the left symbol belt 175L circulates along the circumferential surface. The left stepping motor rotates the rotation shaft of the left stepping motor once by receiving a predetermined number of pulse signals (also called excitation signals or excitation pulses). When the left symbol belt 175L includes 21 symbols arranged at equal intervals in the long side direction (circumferential direction) as in the present embodiment, the rotation axis of the left stepping motor is an integral multiple of “21”. One rotation is performed by transmitting 504 pulse signals. In this case, the number of pulses necessary for switching from an arbitrary symbol to the next symbol is 24 pulses (= 504 [number of pulse signals] / 21 [symbol]). The rotation angle of the rotating shaft of the left stepping motor, that is, the relative rotation angle of the left reel 171L is specified by the number of times this pulse signal is received. Hereinafter, a pulse signal for driving the left stepping motor is also referred to as a “drive signal”.

  The reel index sensor includes a pair of light emitting elements and light receiving elements. The light emitting element and the light receiving element are fixed to the support plate so as to be aligned in the radial direction of the left reel 171L at a predetermined interval. The light emitting element emits inspection light, and the light receiving element receives inspection light from the light emitting element. The light blocking plate has a base end portion fixed to the boss reinforcing plate of the left reel and a tip end portion bent substantially at right angles to the base end portion, and circulates as the left reel 171L rotates. . The tip is disposed so as to pass through the gap between the light emitting element and the light receiving element every time the left reel 171L rotates, and when passing through the gap, inspection light from the light emitting element to the light receiving element is transmitted. Cut off. By detecting the interruption of the inspection light due to the passage of the tip portion, the position of the light receiving element fixed to the housing 101 (hereinafter also referred to as “fixed reference point”) and the tip portion fixed to the left reel 171L. It can be detected that the rotation position is the same, that is, that the position of the fixed reference point and the rotation position of the reel reference point are the same. From the reel reference point detection device, a position detection signal is transmitted to the main control board 301 every time a block of inspection light is detected. Accordingly, the main control board 301 can confirm that the reel reference point has passed the fixed reference point based on the detection of the position detection signal.

  The rotational position of the reel reference point is determined by detecting that the reel reference point has passed the fixed reference point and specifying the relative rotation angle of the reel reference point with respect to the fixed reference point. That is, the absolute rotational position of the reel reference point can be specified by the number of pulse signals transmitted to the reel drive device after receiving the position detection signal from the reel reference point detection device. Therefore, the main control board 301 measures the number of transmitted pulse signals from the time when the position detection signal is input, so that the number of symbols from the reference symbol located at the reel reference point passes through the fixed reference point. In addition, it is possible to determine how many times a pulse signal should be transmitted to the left stepping motor in order to stop a predetermined symbol at a fixed reference point. As a result, the predetermined symbol on the left reel 171L can be accurately stopped at the target position.

  In the above description, the left reel 171L has been described, but each of the middle reel 171M and the right reel 171R is substantially the same as the left reel 171. In this embodiment, a cylindrical reel skeleton with endlessly attached symbol belts 175L, 175M, and 175R on each reel 171L, 171M, and 171R is rotated, but the endless symbol belt is rotated. Any other configuration may be used as long as it can be configured.

  Here, with respect to the symbols drawn on the left symbol belt 175L of the left reel 171L, the middle symbol belt 175M of the middle reel 171M, and the right symbol belt 175R of the right reel 171R, refer to FIGS. 5 (a) to 5 (c). While explaining. As shown in FIGS. 5A to 5C, each of the left symbol belt 175L, the middle symbol belt 175M, and the right symbol belt 175R has a “red 7” symbol (for example, in the left symbol belt 175L). No. 11 symbol), “Blue 7” symbol (for example, No. 18 symbol on the left symbol belt 175L), “Yellow 7” symbol (for example, No. 4 symbol on the left symbol belt 175L), “Replay” symbol (eg, No. 10 symbol on left symbol belt 175L), “Watermelon” symbol (eg, No. 7 symbol on left symbol belt 175L), and “Bell” symbol (eg, left symbol belt) 2nd symbol in 175L). Also, the left design belt 175L has a “red cherry” design (No. 1 design), a “blue cherry” design (No. 8 design), and a “yellow cherry” design (No. 15 design). The middle symbol belt 175M and the right symbol belt 175R include the “cherry” symbol (for example, the fourth symbol in the middle symbol belt 175M). In the present embodiment, the case where the number of symbols in each of the left symbol belt 175L, the middle symbol belt 175M, and the right symbol belt 175R is 21 is illustrated, but the number of symbols may be 20 or less. It may be more than one.

In addition, when a combination of three symbols including only the “yellow 7” symbol is confirmed and displayed along any of the active lines (regular bonus combination winning), the game proceeds to the regular bonus game state. In addition, when a combination of three symbols including only the “replay” symbol is displayed along one of the active lines (usually a replay winning), at least one “replay” symbol and at least one “bell” symbol are displayed. ”And a combination of symbols including only“ Replay ”and“ Bell ”symbols is displayed along one of the active lines (special replay winning prize), the game moves to the replaying state. . In addition, when a combination of symbols including only the “watermelon” symbol is displayed along one of the active lines (winning as a watermelon), the “bell” symbol is displayed fixed along one of the active lines. If it is (usually a prize for the role of the bell), if the “Bell” symbol is confirmed and displayed along one of the middle combination lines (a prize for the special bell role), the symbol “Red 7”, the symbol “Blue 7” or “Yellow” When a combination of symbols including “7” symbol, “Bell” symbol, and “Bell” symbol in this order is displayed along one of the active lines (winning of 3 choice bells), “Red Cherry” symbol, When a combination of symbols including the “blue cherry” symbol or the symbol “red cherry” symbol is confirmed and displayed along one of the active lines (winning for the three-choice cherry role), a predetermined number of medals are paid out respectively. It is.

  In the present embodiment, the normal replay role, the special replay role, the normal bell role, and the special bell role are complete winning combinations. Each symbol constituting the normal replay role, special replay role, normal bell role, and special bell role can be stopped at any effective line by the slip stop control of less than 5 symbols in a general slot machine. The left symbol belt 175L, the middle symbol belt 175M, and the right symbol belt 175R are all arranged at intervals of at least four symbols or less, and are controlled to stop as such. If two types of complete winning combination are won at the same time, one of them wins. On the other hand, a big bonus combination, a regular bonus combination, a watermelon role, a 3-option bell role, and a 3-option cherry role are incomplete winning combinations.

  In the slot machine 100, a game mode using a real medal and a game mode using a real medal and a credit medal can be selectively performed. This selection is made by the player. In the following, a game mode that uses only real medals is referred to as “direct mode”, and a game mode that uses both real medals and credit medals is referred to as “credit mode”. In the direct mode, surplus medals inserted exceeding the maximum number are returned, and medals earned at the time of winning a prize are paid out in kind. On the other hand, in the credit mode, surplus medals inserted exceeding the maximum prescribed number and medals obtained at the time of winning are deposited as credit medals until the number of credits reaches the maximum number of credits (50 in this embodiment).

The processing burden is reduced.

  A control process executed by the MPU 310 in the main control board 301 will be described. The control process of the MPU 310 is roughly divided into a main process that is activated in response to power recovery by restarting the supply of external power or turning on a power switch, and an interrupt process that interrupts the main process. For convenience of explanation, after describing the interrupt process, the main process will be described. As interrupt processing, there are power failure interrupt processing for interrupting in response to reception of a power failure signal at the NMI terminal, and timer interrupt processing for periodically interrupting by measuring time with a timer.

  First, the power failure interrupt process will be described. FIG. 7 is a flowchart showing an example of a power failure interrupt process in the main control board 301. When a power failure occurs, a power failure signal is generated by the power failure monitoring circuit 300b of the power supply board 300 and output to the main control board 301. In main control board 301, an NMI terminal of MPU 310 receives a power failure signal, and an interrupt process (hereinafter referred to as “power failure interrupt process”) for setting a power failure flag in response to the reception of the power failure signal is executed.

  In the power failure interrupt process, first, the register data used in the MPU 310 is saved in the backup area in the RAM 313 (register save process S101). After the register saving process S101, a power failure flag is set (power failure flag setting process S102). The power failure flag is information held in a specific area (power failure flag storage area) in the RAM 313 and representing the occurrence of a power failure state. After the power failure flag setting process S102, the register data saved in the backup area of the RAM 313 in the register save process S101 is returned to the register of the MPU 310 (register return process S103). The power failure interrupt process is completed upon completion of the register restoration process S103. If the power failure flag setting process S102 can be performed without destroying the data of the register being used by the MPU 310, the register saving process S101 and the register restoration process S103 can be omitted.

  Next, timer interrupt processing will be described. FIG. 8 is a flowchart showing timer interrupt processing in the main control board 301. In the main control board 301, timer interrupt processing is periodically performed. In the present embodiment, the timer interrupt process is substantially performed at a period of 1.49 ms [milliseconds].

  In the timer interrupt process, first, all the register values used in the normal process in the main process (see FIG. 11) described later in the MPU 310 are stored in the backup area of the RAM 313 (register save process S201). After the register saving process S201, it is confirmed whether or not a power failure flag is set (S202). When the power failure flag is set, the backup process S203 is executed.

  Here, the backup process S203 will be described in detail. FIG. 9 is a flowchart showing the backup process executed in the timer interrupt process in the main control board 301.

  In the backup process S203, as shown in FIG. 9, it is first determined whether or not the transmission of various commands stored in the ring buffer has ended (S301). If the transmission of these commands has not ended, the backup process is temporarily ended and control returns to the timer interrupt process. This is control for completing the transmission of the command before starting the backup process. On the other hand, when the transmission of these commands is completed, the value of the stack pointer of the MPU 310 is saved in the backup area in the RAM 313 (stack pointer saving process S302). After the stack pointer saving process S302, a RAM determination value, which will be described later, is cleared and the output state of the output port in the input / output port 314 is cleared, and all actuators (not shown) are turned off (stop process S303).

  After the stop process S303, a new RAM determination value is calculated and stored in the backup area (RAM determination value storage process S304). The RAM determination value is a 2's complement of the checksum value in the work area of the RAM 313. Here, the 2's complement of the tick sum value is a value generated when each digit (bit) of the check sum value is inverted in binary representation. In this case, the value obtained by adding 1 to the exclusive OR (“FFFF”) of the checksum value of the RAM 313 and the RAM determination value is “0”.

  After the RAM determination value saving process S304, access to the RAM 313 is prohibited (RAM access prohibition process S305). Thereafter, an infinite loop is entered in preparation for the case where the processing cannot be executed due to complete interruption of the internal power. Note that, for example, when the power failure flag is erroneously set due to noise or the like, although not shown, it is confirmed whether the power failure signal is still input before entering the infinite loop. If the power failure signal has not been input, the internal power supply has been restored. Therefore, writing to the RAM 313 is permitted, the power failure flag is canceled, and the timer interrupt process is resumed. On the other hand, if the power failure signal is continuously input, the infinite loop is entered as it is.

  In this way, it is determined whether or not the command transmission is completed at the initial stage of the backup process S203, and when the transmission is not completed, the transmission process is given priority. By adopting a configuration in which the backup process is executed after the command transmission process is completed, it is not necessary to construct a power failure processing program considering that the backup process is executed during the command transmission. As a result, it is possible to simplify the program related to the processing at the time of a power failure and to reduce the capacity of the ROM 312.

  The power supply circuit 300a of the power supply board 300 outputs backup power used as drive power for the control system for a sufficient time to complete the power failure interrupt process and the backup process even after a power failure occurs. With this backup power, backup processing of power failure interrupt processing and timer interrupt processing is performed. In this embodiment, backup power is continuously output for 30 ms [milliseconds] after the occurrence of a power failure.

  Returning to the description of the timer interrupt process, as shown in FIG. 8, when it is determined in the determination process S202 that the power failure flag is not set, the watchdog timer for monitoring the occurrence of malfunction is initialized. Then, an interrupt permission is issued to the MPU 310 itself (interrupt end declaration process S204). After the interrupt termination declaration process S204, with reference to the left drive stop flag, the middle drive stop flag, and the right drive stop flag, the stepping motors such as the left stepping motor 172L are driven to rotate the reels 171L, 171M, and 171R. A signal is transmitted (stepping motor control process S205). Specifically, if the left drive stop flag is not set, a drive signal is transmitted to the left stepping motor of the left reel 171L. The middle reel 171M and the right reel 171R are similar to the case of the left reel 171L.

  After the stepping motor control process S205, switch state changes in various devices connected to the input / output port 314 are monitored (switch read process S206). After the switch reading process S206, sensor state changes in various devices connected to the input / output port 314 are monitored (sensor monitoring process S207). After the sensor monitoring process S207, various counter values and various timer values are calculated (timer calculation process S208). After the timer calculation process S208, the number of bets and the number of acquired medals are output to the external concentration terminal board 126 in order to add up the difference number (difference between the total number of bets and the total number of acquisitions) (difference number counting process S209).

  After the difference number counting process S209, various commands stored in the ring buffer are transmitted to the sub-control board 302 (command output process S210). After the command output process S210, segment data to be displayed on the credit number display device 105, the acquired number display device 115, etc. is set (segment data setting process S211). The segment data set in the segment data setting process S211 is transmitted to a predetermined display device such as the credit number display device 105 (segment data display process S212). A display device such as the credit number display device 105 displays numbers, symbols, and the like corresponding to the received segment data.

  After the segment data display process S212, control data and commands to the sub-control board 302 are output from the input / output port 314 to various output devices (port output process S213).

  Here, the port output processing S213 will be described with reference to FIG. FIG. 10 is a flowchart showing the port output process S213. In the port output process S213, control data set in various processes is sequentially output (communication information output process S1001). Next, it is determined whether there is a command to be transmitted to the sub-control board 302 set in various processes (S1002). If there is no command to be transmitted to the sub-control board 302, the port output process S213 ends.

  On the other hand, when there is a command to be transmitted to the sub-control board 302, the solid identification information (hereinafter also referred to as “unique ID”) of the CPU 311 is obtained when the command is transmitted for the first time after the start of power supply. When the command transmission is acquired for the second time and thereafter, the value is acquired as conversion initial information from the hardware random number counter mounted on the main control board 301 (conversion initial information acquisition processing S1003). A linear feedback shift operation corresponding to 16 bits is performed on the conversion initial information to generate first conversion information (conversion information update processing S1004), and the upper word of the command to be transmitted is exclusive to the first conversion information An OR operation is executed to convert the upper word (upper word conversion processing S1005). The first conversion information is subjected to the same linear feedback shift operation corresponding to 16 bits as the conversion information update processing S1004 to generate second conversion information (conversion information update processing S1006), and the command to be transmitted An exclusive OR operation of the lower word and the second conversion information is executed to convert the lower word (lower word conversion processing S1007). Thereby, since the command to the sub-control board 302 is a command of 2 words (32 bits), the entire command is converted. After the lower word conversion process S1007, the conversion initial information, the converted upper word, and the converted lower word are sequentially transmitted to the sub control board 302 (sub communication information output process S1008). The command conversion mode and transmission mode will be described again in detail in the description of the characteristic part.

  Returning to the description of the timer interrupt process, after the port output process S213, the data of each register saved in the backup area in the register save process S201 is restored to the corresponding register in the MPU 310 (register return process S214). After the register restoration process S214, the next timer interrupt is permitted (interrupt permission process S215). A series of timer interrupt processing is completed through the above processing.

  A main process in the main control board 301 will be described. FIG. 11 is a flowchart showing the main process of the main control board. The main process of the main control board 301 is executed when returning from the power failure state.

  In the main process of the main control board 301, first, an initial value of the stack pointer is set (stack pointer setting process S401). After the stack pointer setting process, an interrupt mode permitting the interrupt process is set (interrupt mode setting process S402). After the interrupt mode setting process S402, various settings for the register group, the I / O device, and the like in the MPU 310 are performed (register setting process S403).

  After register setting processing S403, whether or not a predetermined operation (operation in which the setting key is inserted into the setting key switch and rotated by a predetermined angle) is performed on the setting key switch of the setting operation permission device 122 is determined. It is determined (S404). When it is determined that a predetermined operation has been performed on the setting key switch, a predetermined plurality of types of probability settings (six settings from “setting 1” to “setting 6” in this embodiment) are selected. Data in all areas of the RAM 313 except for a predetermined area that holds a set value of one probability setting to be selected is forcibly cleared (forced RAM clear processing S405). If the setting key is inserted in a rotated state after the forced RAM clear process S405, the current setting value is changed (setting change), while the setting key is only inserted. In this case, the current setting value is reset (resetting the setting) (probability setting selection process S406). After the probability setting selection process S406, the process proceeds to the normal game process. The details of the probability setting selection process S406 will be described after the main process.

  When it is determined in the determination process S404 that the predetermined operation has not been performed on the setting key switch, the set value of the selected probability setting is a value within a predetermined range (“1” to “6”). It is determined whether or not (S407). Note that the set value is only a value within a predetermined range unless an abnormal situation such as mechanical or electrical destruction of the RAM 313 occurs between the occurrence of a power failure state and the return from the power failure state. Absent. If the set value is within a predetermined range, it is determined whether or not a power failure flag is set (S408). When the power failure flag is set, the checksum value of the work area of the RAM 313 is newly calculated, and it is determined whether or not the new checksum value is normal. The new checksum value is normal means that the new checksum value and the checksum value before the occurrence of the power failure state are the same, that is, the new checksum value and the RAM determination held in the backup area of the RAM 313. It means that the value obtained by adding 1 to the exclusive OR with the value is “0”. This value is “0” when the new checksum value and the checksum value before the occurrence of the power failure are the same, and other than “0” when they are different. Unless an abnormal situation such as mechanical or electrical destruction of the RAM 313 occurs between the occurrence of a power failure state and the return from the power failure state, this value is not “0”.

  When it is determined in the determination process S407 that the set value of the probability setting is not a value within the predetermined range, when it is determined that the power failure flag is not set in the determination process S408, or a new checksum is determined in the determination process S409. When it is determined that the logical sum of the value and the RAM determination value is other than “0”, the interrupt process is prohibited (interrupt prohibition setting process S415). After the interrupt prohibition setting process S415, all output ports of the input / output port 314 are cleared, and all actuators connected to the input / output port 314 are turned off (all output port clear process S416). After all output port clear processing S416, the occurrence of an error is notified (error notification processing S417). This error notification state continues until the power is restored with the setting key inserted into the setting key switch.

  If it is determined in the determination process S409 that the new checksum value is normal, the value of the stack pointer stored in the backup area is written to the stack pointer of the MPU 310, and the value of the stack pointer is before the occurrence of the power failure state. (Stack pointer return processing S410). As a result, after returning from the power failure state, it is possible to resume from the process interrupted by the occurrence of the power failure state. After the stack pointer recovery process S410, a power recovery command indicating recovery from the power failure state is transmitted to the sub-control board 302 (power recovery command transmission process S411).

  After the power recovery command transmission process S411, the state of the stop switch and the state of the automatic settlement switch of the stop change operating device are stored in a predetermined area of the RAM 313 (game form setting process S412).

  After the game form setting process S412, the values of the sensors of various devices are initialized (sensor initialization process S413). After the sensor initialization process S413, the power failure flag is released (power failure flag release process S414). After the power failure flag release processing S414, the processing is resumed from the processing at the address before the occurrence of the power failure state indicated by the stack pointer. Specifically, an interrupt end declaration process S204 after the backup process S203 (see FIG. 8) in the timer interrupt process described above is executed.

  Here, the probability setting selection process S406 will be described in detail. FIG. 12 is a flowchart illustrating an example of the probability setting selection process. In the present embodiment, the set value of the probability setting is any one of “1” to “6”. When playing a game with the same number of bets, as the set value increases from “1” to “6”, the random number table generally has a higher machine discount (the expected value of the total number of medals obtained with respect to the total number of bets medals). Is selected. In general, for the same set value, a random number table with a higher machine discount is selected as the number of bets increases.

  In the probability setting selection process S406, first, it is determined whether or not the setting key switch in the setting operation permission device 122 is in an ON state (S501). Specifically, it is determined whether or not reception of a setting change signal output from setting operation permission device 122 has been received. The setting change signal is received in the switch reading process S206 of the timer interrupt process. If the rotation operation of the setting key at a predetermined angle after the setting key is inserted is not detected, the process is terminated, and the normal game process (see FIG. 13) is started. On the other hand, if rotation of the setting key is detected, interrupt permission is set (interrupt permission setting processing S502). This interrupt permission setting is necessary to read the operation of the start switch of the fluctuation start operating device 113 and the reset switch of the reset operating device 119 in the following. After the interrupt permission setting process S502, the current setting value is read (setting value reading process S503). After the set value reading process S503, it is determined whether or not the read set value is a normal value (an integer from “1” to “6”) (S504). If the set value is not a normal value, the set value is forcibly changed to a predetermined initial value (“1” in the present embodiment) (set value initialization process S505). On the other hand, when the set value is a value from “1” to “6”, the set value initialization process S505 is skipped. Thereafter, the current set value is displayed on the probability setting display device (set value display process S506). After the set value display processing S506, it is determined whether or not the start switch of the fluctuation start operating device 113 has been operated (S507). Specifically, it is determined whether or not the fluctuation start signal output from the fluctuation start operating device 113 is received.

  If the start switch has not been operated, it is determined whether or not the reset switch has been operated (S508). If the reset switch has not been operated, the process returns to the set value display process S506 and waits for input of a start switch operation for ending change of the probability setting or an operation of the reset switch for changing the probability setting. On the other hand, if the reset switch is operated, the set value is updated (set value update process S509). After the set value update process S509, the process returns to the determination process S504. In this embodiment, the set value loops within a predetermined range in accordance with the operation of the reset switch (“1” → “2” →... → “6” → “1” →...) .

  If it is determined in the determination process S507 that the start switch has been operated, it is determined whether or not the setting key switch is in the ON state (S510) as in the process of S501. When the setting key switch is on, the determination process S501 is looped and waited until the setting key switch is turned off. On the other hand, if the setting key switch is not in the on state, interrupt inhibition is set (interrupt inhibition processing S511). After the interrupt prohibition process S511, the current setting value is stored in a predetermined area of the RAM 313 (setting value storage process S512). All areas of the RAM 313 other than the area where the set values are stored are cleared (RAM clear processing S513). After the RAM clear process S513, the normal game process (see FIG. 13) is executed.

  A normal process for performing main control related to the game at the normal time will be described with reference to FIG. FIG. 13 is a flowchart showing normal processing executed by the MPU 310 of the main control board 301.

  The normal game process of the main control board 301 is executed after the probability setting selection process S406 (see FIG. 12) in the main process. In the normal game process, as shown in FIG. 13, first, interrupt permission is set (interrupt permission setting process S601). After the interrupt permission setting process S601, the state of the stop switch for determining the game form and the state of the automatic settlement switch are stored in the RAM 313 (game form setting process S602). The game form setting process S602 is the same process as the game form setting process S412 (see FIG. 11) in the main process.

  After the game form setting process S602, the process proceeds to the loop process described below. In the following, a case where a continuous game is in progress will be described.

  The RAM 313 clears the data in the area holding the information that changes for each unit game (game information clear process S603). Specifically, information related to the previous game is cleared. Examples of information to be cleared include information related to random numbers, information related to reel device control, information related to winning, and information related to errors. Information related to winning includes information such as winning symbols, winning lines, and number of medals.

  After the game information clear process S603, it waits while performing a predetermined process until a change start signal (change start information) is input from the change start operating device 113 (change wait process S604). Here, the fluctuation waiting process S604 will be described in detail with reference to FIG. FIG. 14 is a flowchart illustrating an example of the variation standby process S604.

  In the variable waiting process S604, first, a game monitoring timer is set (game monitoring timer setting process S701). Here, the setting of the game monitoring timer means that the value of the timer is reset and a new time measurement by the timer is started. The game monitoring timer is a timer for measuring a game interval. When a predetermined time elapses when the game is not played by the player, the image on the auxiliary display device 118 is transferred to a predetermined image (demonstration image). Used to make

  After the game monitoring timer setting process S701, it is determined whether or not the replay has been won in the previous game. If the replay has been won, the number of medals equal to the number of bets in the previous game is automatically set. Are automatically bet (automatic betting process S702).

  After the automatic betting process S702, it is confirmed whether or not a medal acceptance error has occurred in the inserted medal detection device 203. If an acceptance error has occurred, the acoustic device 110, the light emitting device 117, and the auxiliary display device. A selector error command for notifying 118 of an error is set (selector error notification processing S703). Specifically, it is determined whether or not a selector error flag indicating the occurrence of an error is set. If the selector error flag is set, a selector error command (a type of error command) is sent to the ring buffer. Stored. Further, when an upstream medal detection signal or a downstream medal detection signal is received from the inserted medal detection device 203 in the medal acceptance prohibited state, the selector error command is stored in the ring buffer. The selector error command stored in the ring buffer is output to the sub control board 302 in the command output process S210 of the timer interrupt process executed after the storage. In the following, various commands stored in the ring buffer are output to the sub-control board 302 in the command output process S210 of the timer interrupt process executed after the storage, as in the case of the selector error command.

  After the selector error notification process S703, it is determined whether an error has occurred in the hopper device 109. If an error has occurred in the hopper device 109, the acoustic device 110, the light emitting device 117, and the auxiliary display device 118 are detected. Etc., a hopper error command for notifying the error is set (hopper error notification processing S704). Specifically, it is determined whether or not the release medal detection signal from the release medal detection device 247 is received within a predetermined time after the release control signal is transmitted to the hopper device 109, and the release medal detection signal is received. If not, a hopper error command (a type of error command) is stored in the ring buffer. Further, even when the release medal detection signal is received when the release control signal is not transmitted, the hopper error command is stored in the ring buffer.

  If a settlement signal is received from the settlement operating device 108 after the hopper error notification process S704, settlement of credit medals and bet medals is performed (settlement process S705). In the settlement process S705, a bet settlement start command indicating the start of bet medal settlement, a bet settlement end command representing the end of bet medal settlement, a credit settlement start command representing the start of credit medal settlement, as necessary. A medal release command such as a credit settlement end command representing the end of the credit medal settlement is appropriately stored in the ring buffer.

  Here, the settlement process S705 will be described in detail with reference to FIG. FIG. 15 is a flowchart illustrating an example of the settlement process S705.

  In the settlement process S705, as shown in FIG. 15, it is first determined whether or not a settlement signal (settlement information) from the settlement operation apparatus 108 is received (S801). If the settlement signal has not been received, the settlement process S705 ends. If the settlement signal has been received, it is determined whether or not the game mode is the credit mode (S802). When the game mode is the credit mode, it is determined whether or not the number of credits is 0 (the presence or absence of a credit medal) (S803). If the number of credits is not 0, the credit medal is settled (credit medal settlement process S804). On the other hand, when the number of credits is 0, the credit medal settlement process S804 is skipped. When it is determined in the determination process S803 that the credit number is 0 and after the credit medal settlement process S804, it is determined whether or not the bet number is 0 (presence of bet medal) (S805). If the bet number is not 0, bet medals are settled (bet medal settlement process S806). On the other hand, if the bet number is 0, the bet medal settlement process S806 is skipped. After the bet medal settlement process S806 and when it is determined in the determination process S802 that the game mode is not the credit mode, the game mode is changed from the credit mode to the direct mode or from the direct mode to the credit mode (mode change process S807). . When the mode is changed to the direct mode, the credit amount display device 105 is turned off (lights off).

  In the credit medal settlement process S804, a discharge control signal for instructing the discharge of one medal is transmitted to the hopper device 109 (see FIG. 2) by the same number as the credit number. The hopper device 109 ejects medals every time a release control signal is received. The released medal detection device 247 detects the release of medals from the hopper device 109 one by one, and generates a released medal detection signal for each detection. In the credit medal settlement process S804, the time from transmission of the release control signal to reception of the release medal detection signal is measured by the hopper monitoring timer, and when the measurement time by the hopper monitoring timer exceeds a predetermined time, Set the error flag. As a result, a hopper error is notified when, for example, the hopper device 109 eventually becomes empty. The bet medal settlement process S806 is the same process as the credit medal settlement process S804.

  Returning to the description of the fluctuation waiting process S604, after the settlement process S705, as shown in FIG. 14, the output signal from the inserted medal detection device 203 (the upstream medal detection signal from the upstream medal detection unit, the downstream medal detection unit from Based on the downstream medal detection signal), the acceptance of the actual medal is confirmed (medal acceptance confirmation processing S706). Specifically, a first passage condition in which only the upstream medal detection signal is received within a predetermined allowable passage time, and a second passage condition in which both the upstream medal detection signal and the downstream medal detection signal are received. Only when the third passage condition in which only the downstream medal detection signal is received and the fourth passage condition in which neither the upstream medal detection signal nor the downstream medal detection signal is received are sequentially satisfied in this order. , To accept the medal. When an upstream medal detection signal or a downstream medal detection signal is detected at other timing or order, a selector error flag for notifying an error is set. Whether or not the above condition is satisfied is determined by executing the medal acceptance confirmation process S706 a plurality of times. Further, when neither the upstream medal detection signal nor the downstream medal detection signal is received, this process is skipped. Whether or not to accept the medal is not determined by performing this process only once, but is finally determined by repeatedly performing this process.

  After the completion of the medal acceptance process S707, it is determined whether or not the bet number is less than the minimum prescribed number. If the bet number is less than the minimum specified number (same as the maximum specified number in the present embodiment), the selector error notification process S703 to the medal acceptance process S707 are repeated. On the other hand, if the bet number is not less than the minimum prescribed number, it is determined whether or not a variation start signal is received from the start switch of the variation start operating device 113. When the fluctuation start signal is not received, the selector error notification process S703 to the determination process S708 are repeated. On the other hand, when the fluctuation start signal is received, the path switching solenoid of the selector 190 is driven and the reception prohibition command is set (medal reception prohibition processing S710). Through the above processing steps (S701 to S710), the fluctuation waiting process S604 is completed.

  Returning to the description of the normal game process, after the change waiting process S604, as shown in FIG. 13, the value of the random number counter latched by hardware when the start switch of the change start operating device 113 is operated is displayed. It is read out and stored in the RAM 313 (random number generation process S605). When the start switch is operated, the random number counter is latched by hardware so that the operation of the start switch and the acquisition of the random number value are synchronized in time. Although the value of the random number counter can be read by software, in this case, the time from the operation of the fluctuation start operating device 113 to the acquisition of the random number value is more uneven than in the case of latching in hardware. .

  After the random number generation process S605, the winning combination corresponding to the random value acquired in the random number generation process S605 is determined by referring to the random number table corresponding to the probability setting, the number of bets, and the gaming state, and according to the type of the winning combination Winning flags (for example, Big Bonus Winning Flag, Regular Bonus Winning Flag, Cherry Winning Flag, Bell Winning Flag, Watermelon Winning Flag, Replay Winning Flag) are set. A set value command representing a value is set (internal lottery process S606). Winning roles include, for example, a big bonus role (hereinafter also referred to as “BB”), a regular bonus role (hereinafter also referred to as “RB”), various small roles (cherry role, bell role, watermelon role), replay role And the role of losing. Note that a plurality of types of winning combinations may be selected in one game.

  After the internal lottery process S606, based on the winning combination, the number of bets and the gaming state, one of the manual stop control table groups held in the ROM 312 is used to control each reel device 170L, L170M, 170R of the symbol display variation unit 103. The manual stop control table is selected as the reference stop control table, and the table number of the reference stop control table is stored in a predetermined area of the RAM 313 (rotation initialization process S607). When the winning combination is other than losing, an effective line or the like for winning the winning combination is determined according to the reference stop control table, and each reel unit (170L, 170L, When the stop switch corresponding to L170M, 170R) is operated, slip control is performed to rotate the reel extra within a predetermined range (maximum 4 symbols) in order to win the winning combination as much as possible on the predetermined active line. Done. When the winning combination is lost, the same slip control is performed in order to prevent other winning combinations from winning. This reference stop control table is not necessarily referred to. In this embodiment, the three stop operation units (231, 232, 233) of the variable stop operation device 114 are arranged in a predetermined order (for example, “left reel stop operation”). Section 231 → middle reel stop operation unit 232 → right reel stop operation unit 233 ”and“ left reel stop operation unit 231 → right reel stop operation unit 233 → middle reel stop operation unit 232 ”). In the case of another operation sequence, the predetermined symbol pattern is stopped by reselecting the reference stop control table from the manual stop control table group, by another control method, or using them.

  After the rotation initialization process S607, a symbol variation standby process S608 is executed. In the symbol variation standby process S608, first, it is determined whether or not the measurement time by the symbol variation monitoring timer is equal to or longer than a predetermined specified time (for example, 4.1 seconds). Here, the “symbol variation monitoring timer” is a timer that measures the elapsed time from the symbol variation start time in the previous symbol display variation unit 103. If the measurement time of the symbol fluctuation monitoring timer is less than a predetermined specified time, a variable waiting command (internal state command of the internal state command) indicating that the specified time has elapsed (hereinafter referred to as “variable waiting state”). Is stored in the ring buffer. Note that the player is informed of the variable standby state by a variable standby state display device (not shown). After that, until the measurement time of the symbol fluctuation monitoring timer becomes equal to or longer than the predetermined specified time, whether or not the measurement time by the symbol fluctuation monitoring timer is equal to or longer than the predetermined specified time while the change waiting state is notified. Is repeated. On the other hand, when the measurement time of the symbol fluctuation monitoring timer is equal to or longer than the predetermined specified time, the symbol fluctuation monitoring timer is reset and started, the notification of the standby state for the specified time is stopped, and the predetermined specified time has elapsed. A specified time lapse command (a kind of internal state command) indicating this and a bet number command for outputting to the external concentration terminal board are stored in the ring buffer. Thereafter, information related to control of each stepping motor (such as the left stepping motor) of the symbol display variation unit 103 in a predetermined area of the RAM 313 is initialized for starting rotation. Note that actual driving of each stepping motor is controlled by stepping motor control processing S205 of timer interruption processing.

  After the symbol fluctuation standby process S608, a rotation control process S609 for controlling the rotation of each reel 171L, 171M, 171R in the symbol display fluctuation unit 103 is executed. Here, the rotation control process S609 will be described in detail with reference to FIG. FIG. 16 is a flowchart illustrating an example of the rotation control process S609.

  In the rotation control process S609, information on the rotation of each reel device 170L, 170M, 170R in a predetermined area of the RAM 313 is initialized, and an all reel rotation command ( A kind of reel rotation information command) and a symbol change state command (a kind of internal state command) indicating the symbol display change state in the symbol display change unit 103 are stored in the ring buffer (rotation start processing S1101). After the rotation start process S1101, the process waits until a predetermined stop standby time elapses (design stop standby process S1102). The “predetermined stop standby time” in the symbol stop standby process S1102 is substantially the same as the average time required from the start of rotation of each reel 171L, 171M, 171R to the steady rotation at a constant speed. After the symbol stop standby process S1102, it is determined whether or not the rotation of all the reels 171L, 171M, and 171R is a steady rotation (S1103). Specifically, whether or not these rotations are steady rotations is determined by whether or not a position detection signal is received from the reel reference point detection device corresponding to the reel that has started rotating last. If the position detection signal is received, it is determined that the rotations are steady rotations. If the position detection signal is not received, it is determined that the rotation of any of the reels is not steady rotations. . If these rotations are not steady rotations, the determination process S1103 is repeatedly executed. In this embodiment, all the reels (171L, 171M, 171R) start to rotate simultaneously.

  When it is determined in the determination process S1103 that the rotation of all reels is a steady rotation, it is determined whether or not the maximum bet switch of the bet operation unit 213 has been operated. On the other hand, if no operation is performed, the navigation command is stored in the ring buffer (navigation change input monitoring process S1104). After the navigation change input monitoring process S1104, a process of stopping the symbol variation is executed.

  It is determined whether or not a left stop signal (a type of variation change information) is received from the left reel stop operation unit 231 of the variation stop operation device 114 (S1105). If the left stop signal has not been received, it is determined whether or not a middle stop signal (a type of variation change information) has been received from the middle reel stop operation unit 232 (S1106). If the middle stop signal has not been received, it is determined whether or not a right stop signal (a type of variation change information) from the right reel stop operation unit 233 has been received (S1107). When the right stop signal is not received, that is, when none of the left stop signal, the middle stop signal, and the right stop signal are received, the navigation change input monitoring process S1104 is executed.

  If it is determined in the determination process S1105 that the left stop signal has been received, it is determined whether the left drive flag is set (S1108). The “left drive flag” is a flag for identifying whether the left reel 171L is rotating or stopped, and is set when rotation of the left reel 171L is started. When the left drive flag is released, it indicates that the left reel 171L is substantially stopped, and when the left drive flag is set, it indicates that the left reel 171L is substantially rotating. Represent. When the left drive flag is released, the navigation change input monitoring process S1104 is executed. On the other hand, when the left drive flag is set, the left reel stop process S1109 is executed. In the left reel stop process S1109, first, the left stepping motor that rotates the left reel 171L is stopped with reference to the reference stop control table selected in the rotation initialization process S607. After the left stepping motor is stopped, a left drive flag is set, the number of stopped reels is incremented, a left reel stop command (a kind of reel rotation information command) indicating that the left reel 171L is stopped, and a stop of the left reel 171L A left reel symbol command (a kind of stop symbol command) representing a symbol is stored in the ring buffer. The “number of stopped reels” represents the number of reels that are stopped, and is reset to “0” in the rotation start processing S1101.

  Here, the control when the left stepping motor of the left reel device 170L is stopped will be described in detail. Based on the current number of drive signal transmissions (a part of the symbol display information), the reference stop control table is referenced to determine the number of transmissions of the drive signal (drive information). If the winning flag of big bonus combination, regular bonus combination, various small combinations or re-playing combination is set, it is possible as long as the winning combination is not established The number of transmissions is determined so that the winning symbol pattern stops along any of the active lines. For example, when a small role that “watermelon” symbols are arranged along the lower line L3 is selected and the left reel stop operation unit 231 is operated at a timing when the “watermelon” symbols pass the upper row, it stops at the lower level. In this way, the left reel 171L is slid by two symbols. It should be noted that the range that can be slid is determined in advance, and depending on the operation timing of the left reel stop operation unit 231, the “watermelon” symbol may not stop at the lower stage. Even in this case, if the “watermelon” symbol can be stopped at the middle or upper level, the “watermelon” symbol is controlled to stop at the middle or upper level regardless of the planned pay line. “Number of drive signal transmissions” represents the number of transmissions of drive signals transmitted to the left stepping motor, and the value is “0” in response to reception of a position detection signal from the reel index sensor of the left reel device 170L. Reset to. Specifically, in the left reel stop process S1109, it is confirmed that the transmission of the drive signal for the determined number of transmissions has been completed with reference to the drive signal transmission number, and the left drive flag (“drive change information”). ). In stepping motor control process S205 of the timer interrupt process shown in FIG. 8, the release of the left drive flag is confirmed and transmission of the drive signal is stopped. Thereby, after determining the number of transmissions, the drive signal is repeatedly transmitted to the left stepping motor by that number of times.

  After the left reel stop processing S1109, it is determined whether or not the number of stopped reels is 3 (S1110). If the number of stop reels is not 3, that is, if at least one reel is rotating (during symbol variation), it is determined whether or not the reference stop control table needs to be changed (S1111). If it is necessary to change the reference stop control table when stopping an unstopped reel, the reference stop control table is changed to another manual stop control table selected from the manual stop control table group (control table change processing S1112). ). In the control table changing process S1112, the stop position of the reel that has already stopped among the middle reel 171M and the right reel 171R is referred to together with the stop position of the left reel 171L. As a case where the reference stop control table needs to be changed, for example, there is a case where a combination other than the winning combination wins.

  If it is determined in the determination process S1106 that the middle stop signal has been received, it is determined whether or not the middle drive flag is set (S1113). As in the case of the left drive flag, the “middle drive flag” is a flag for identifying whether the middle reel 171M is rotating or stopped. When the middle drive flag is released, the navigation change input monitoring process S1104 is executed. On the other hand, if the medium drive flag is set, it is determined whether or not the number of stopped reels is 0 (S1114). If the number of stopped reels is not 0, middle reel stop processing S1116 is executed. On the other hand, when the number of stop reels is 0, a predetermined manual stop control table in the manual stop control table group is reset as the reference stop control table (control table resetting process S1115), and the control table resetting process S1115. After that, the middle reel stop process S1116 is executed. Note that the middle reel stop process S1116 is the same process as in the case of the left reel stop process S1109. In the middle reel stop processing S1116, first, the middle drive flag (a kind of “drive change information”) is set with reference to the reference stop control table, and the middle stepping motor in the middle reel device 170M is stopped. The control for stopping the middle stepping motor is substantially the same as the control for stopping the left stepping motor. After stopping the middle stepping motor, the number of stopped reels is incremented, and a middle reel stop command (a kind of reel rotation information command) indicating that the middle reel 171M is stopped and a middle reel representing a stop pattern of the middle reel 171M. A symbol command (a kind of stop symbol command) is stored in the ring buffer.

  After the middle reel stop process S1116, it is determined whether or not the number of stopped reels is 3 (S1117). If the number of stopped reels is not 3, it is determined whether or not the reference stop control table needs to be changed when stopping an unstopped reel (S1118). When the reference stop control table needs to be changed, the reference stop control table is changed to another manual stop control table selected from the manual stop control table group (control table change processing S1119). In the control table change process S1119, the stop position (stop symbol) of the already stopped reels of the left reel 171L and the right reel 171R is referred to together with the stop position of the middle reel 171M.

  If it is determined in the determination process S1107 that the right stop signal has been received, it is determined whether or not the right drive flag is set (S1120). The “right drive flag” is a flag for identifying whether the right reel 171R is rotating or stopped, as in the case of the left drive flag and the middle drive flag. When the right drive flag is released, the navigation change input monitoring process S1104 is executed. On the other hand, if the right drive flag is set, it is determined whether or not the number of stopped reels is 0 (S1121). If the number of stopped reels is not 0, right reel stop processing S1123 is executed. On the other hand, when the number of stop reels is 0, a predetermined manual stop control table in the manual stop control table group is reset as the reference stop control table (control table resetting process S1122), and the control table resetting process S1122 is performed. After that, the right reel stop process S1123 is executed. The right reel stop process S1123 is the same process as the left reel stop process S1109. In the right reel stop process S1123, first, referring to the selected manual stop control table, a right drive flag (a kind of “drive change information”) is set, and the right stepping motor in the right reel device 170R is stopped. . The control for stopping the right stepping motor is substantially the same as the control for stopping the left stepping motor. After the stop of the right stepping motor, the number of stopped reels is incremented, and a right reel stop command (a kind of reel rotation information command) indicating that the right reel 171R is stopped and a right reel design indicating a stop pattern of the right reel A command (a type of stop symbol command) is stored in the ring buffer.

  After the right reel stop process S1123, it is determined whether or not the number of stopped reels is 3 (S1124). If the number of stopped reels is not 3, it is determined whether or not the reference stop control table needs to be changed when stopping an unstopped reel (S1125). When the reference stop control table needs to be changed, the reference stop control table is changed to another manual stop control table selected from the manual stop control table group (control table change processing S1126). In the control table change process S1126, the stop position (stop symbol) of the already stopped reels of the left reel 171L and the middle reel 171M is referred to together with the stop position of the right reel 171R.

  Returning to the description of the normal game process, a winning symbol determination process S610 is executed after the rotation control process S609 as shown in FIG. In the winning symbol determination process S610, first, it is determined whether or not the symbol pattern for each active line is a winning symbol pattern, and whether or not a winning combination is established and whether or not a winning flag is established. It is inspected that no part other than the current role has won. In the present embodiment, all symbol patterns of the four combination lines L2 to L5 (see FIG. 3) are inspected. When even one winning combination other than the winning combination is won, error processing for notifying the occurrence of a winning error is executed. On the other hand, if only the winning combination is winning, a winning flag corresponding to all winning winning combinations (for example, big bonus winning flag, regular bonus winning flag, cherry winning flag, bell winning flag, watermelon winning flag, A replay winning flag) is set. Further, the number of acquired medals corresponding to each winning winning combination is added within a range not exceeding the maximum number of acquired medals, so that the number of acquired medals is finally determined. Further, in the winning symbol determination process S610, a winning combination command including information on the type of winning combination, a winning line command including information on the type of winning line, and a winning combination error command including information on winning error are stored in the ring buffer. The

  After the winning symbol determination process S610, an acquired medal payout process S611 is executed. In the acquired medal payout process S611, as shown in FIG. 17, it is first determined whether or not the number of acquired medals is 0 (S1201). When the number of acquired medals is “0”, the acquired medal payout process S611 ends. On the other hand, if the acquired medal number is not “0”, the payout number of acquired medals is set to the same value as the acquired medal number (scheduled payout number setting process S1202), and the payout number is cleared to “0”. (Payout number clear processing S1203). After the payout amount clear process S1203, it is determined whether or not the game mode is the credit mode (S1204).

  If it is determined in the determination process S1204 that the game mode is the credit mode, it is determined whether or not the number of credits is an upper limit value (S1205). When the number of credits is less than the upper limit value, the number of payouts is incremented (payout number changing process S1206), after which the number of credits is incremented and a credit number change command is stored in the ring buffer (credits). Number change processing S1207). Thereafter, it is determined whether or not the number of payouts is the same as the number of payouts (S1208). When the number of payouts is the same as the number of payouts, the acquired medal payout process S611 ends. On the other hand, when the number of payouts is less than the planned payout number, the process returns to the determination process S1205.

  If it is determined in the determination process S1204 that the game mode is not the credit mode, or if it is determined in the determination process S1205 that the number of credits has reached the upper limit value, an acquired medal payout start command indicating the start of payout of the acquired medal is issued. It is stored in the ring buffer (payout start command setting process S1209). After the payout start command setting process S1209, a payout control process S1210 is executed. In the payout control process S1210, a discharge control signal for instructing discharge of one medal is transmitted to the hopper device 109 (see FIG. 2) until the number of discharges is equal to the number of discharges. The hopper device 109 pays out medals every time a release control signal is received. The released medal detection device 247 detects the release of medals from the hopper device 109 one by one, and generates a released medal detection signal. In the credit medal settlement process S804, the time from the transmission of the release control signal to the reception of the release medal detection signal is measured by the hopper monitoring timer, and if the measurement time by the hopper monitoring timer exceeds the specified release time, the hopper error flag Is set. As a result, a hopper error is notified when the hopper device 109 is finally emptied.

  After the discharge control process 1210, the payout number is incremented (payout number change process S1211). After the payout number changing process S1211, it is determined whether or not the payout number is the same as the planned payout number (S1212). When the number of payouts is the same as the planned payout number, an acquired medal payout end command indicating the end of payout of the acquired medal is stored in the ring buffer (payout end command setting process S1213), and the acquired medal payout process S611 ends. . On the other hand, when the number of payouts is less than the planned payout number, the process returns to the payout control process S1210.

  Returning to the description of the normal game process, after the acquired medal payout process S611, a re-game determination process S612 is performed as shown in FIG. In the re-game determination process S612, when it is determined in the winning symbol determination process S610 that the re-game is won, various processes such as setting the internal state to re-game are performed. Further, a re-game command (a kind of internal state command) indicating that the next game is a re-game is stored in the ring buffer.

  After the re-game determining process S612, an accessory operating process S613 is performed. In the in-community-acting process S613, processes during the actuating of an accessory such as a big bonus and a regular bonus are performed. Here, the processing during the operation of the accessory will be described in detail with reference to FIG.

  In the accessory operating process S613, it is determined whether or not the internal state is a big bonus (S1301). If the internal state is a big bonus, it is further determined whether the internal state is a JAC game or a small role game (S1302). If it is not a JAC game, it is determined whether or not a JACIN symbol pattern (in this embodiment, a combination of three replay symbols) is displayed on the active line as a trigger for transition to the JAC game (S1303). . When the JACIN symbol pattern is displayed on the active line, initialization relating to the JAC game is performed (JAC start processing S1304). In the JAC start process S1304, the internal state is set to a JAC game with a big bonus, and the number of JACs and the number of established JACs are respectively set to predetermined values. On the other hand, when the JACIN symbol pattern is not displayed on the active line, the JAC start process S1304 is skipped.

  If it is determined in the determination process S1302 that the internal state is a JAC game, the number of JAC games is decreased by 1 (JAC number update process S1305). After the JAC number updating process S1305, it is determined whether or not a JAC symbol pattern (in this embodiment, a combination of three replay symbols) is displayed on the active line (S1306). If the JAC symbol pattern is displayed on the active line, the number of established JACs is decreased by 1 (JAC establishment number update processing S1307). On the other hand, if the JAC symbol pattern is not displayed on the valid line, the JAC establishment number update process S1307 is skipped. Thereafter, it is determined whether or not the number of JACs or the number of established JACs is 0 (S1308, S1309). If the number of JACs or the number of established JACs is 0, the internal state is changed to a small role game (JAC end processing S1310). On the other hand, if the number of JACs and the number of established JACs are not 0, the JAC end process S1310 is skipped.

  After passing through the predetermined processes of the above-described processes S1302 to S1310, the number of acquired medals calculated in the winning symbol determination process S610 (see FIG. 13) is added to the total number of acquisitions, and the total number of acquisitions is updated (total acquisition number update process S1311). ). It should be noted that the total number acquired is initialized in the accessory operation determination process S614 (see FIG. 13) described below at the start of the big bonus. After the total acquisition update process S1311, it is determined whether the total acquisition is equal to or greater than the predetermined acquisition number (S1312). When the total number of acquisitions is larger than the specified number of acquisitions, big bonus end processing is performed (BB end processing S1313), and processing for shifting to the RT gaming state, which is the RT gaming state after the big bonus, is performed (RT2 transition processing). S1314). In the RT2 transition process S1314, the internal state is set to the RT2 gaming state, and an RT2 gaming state command (a kind of internal state command) indicating the RT2 gaming state is stored in the ring buffer. On the other hand, when the total acquisition number is less than the predetermined acquisition number, the BB end process S1313 and the RT2 transition process S1314 are skipped. Through the above-described processing steps, the accessory operating process S613 ends.

  If it is determined in the determination process 1301 that the internal state is not a big bonus, it is determined whether or not the internal state is a regular bonus (S1315). If the internal state is not a regular bonus, this process ends. On the other hand, when the internal state is a regular bonus, the number of JAC games is decreased by 1 (JAC number update processing S1316). The number of JACs is initialized to a predetermined number in the accessory action determination process S614 (see FIG. 13) described below at the start of the regular bonus. Note that the number of JACs in the regular bonus may be different from the number of JACs in the big bonus. After the JAC number update process S1316, it is determined whether or not a JAC symbol pattern (in this embodiment, a combination of three replay symbols) is displayed on the active line (S1317). When the JAC symbol pattern is displayed on the active line, the number of established JACs is decreased by 1 (JAC establishment number update processing S1318). The number of established JACs is initialized to a predetermined number in the accessory action determination process S614 (see FIG. 13) described below at the start of the regular bonus. Note that the number of JACs established in the regular bonus may be different from the number of JACs established in the big bonus. On the other hand, if the JAC symbol pattern is not displayed on the valid line, the JAC establishment number update process S1318 is skipped. Thereafter, it is determined whether the number of JACs or the number of established JACs is 0 (S1319, S1320). When the number of JACs or the number of established JACs is 0, the internal state is changed to a small role game (JAC end processing S1321), and a process of shifting to the RT1 gaming state that is the RT gaming state after the regular bonus is performed ( RT1 transition processing S1322). In the RT1 transition process S1322, the internal state is set to the RT1 gaming state, and an RT1 gaming state command (a kind of internal state command) indicating the RT1 gaming state is stored in the ring buffer. On the other hand, if the number of JACs and the number of established JACs are not 0, the JAC end process S1321 and the RT1 transition process S1322 are skipped. Through the above-described processing steps, the accessory operating process S613 ends.

  Returning to the description of the normal game process, after the process of operating an accessory S613, as shown in FIG. In the accessory operation determination process S614, as shown in FIG. 19, it is determined whether or not a big bonus winning flag indicating that the big bonus (BB) is won is set (S1401). If the big bonus winning flag is set, it is determined whether or not a big bonus winning flag indicating that the big bonus has been won is set (S1402). If the big bonus winning flag is set, processing for starting the big bonus is executed (BB start processing S1403). On the other hand, when the big bonus winning flag is not set, the BB start processing S1403 is skipped.

  If the big bonus winning flag is not set in the determination process S1401, it is determined whether or not the regular bonus winning flag indicating that the regular bonus (RB) is won is set (S1404). If the regular bonus winning flag is set, it is determined whether or not a regular bonus winning flag indicating that the regular bonus has been won is set (S1405). When the regular bonus winning flag is set, processing for starting the regular bonus is executed (RB start processing S1406). On the other hand, if the regular bonus winning flag is not set, the RB start process S1406 is skipped. Through the above process, the accessory operation determination process S614 ends.

  After the combination act determination process S614, it is determined whether the RT1 state that has entered after the big bonus and the RT2 state that has entered after the regular bonus satisfy the end condition. If the end condition is satisfied, the internal state Is set to the normal gaming state, and a normal gaming state command (a kind of internal state command) indicating the normal gaming state is stored in the ring buffer. Specifically, the RT1 state is terminated by the completion of a predetermined number of unit games (for example, 100 times) in the RT1 state or a special replay winning. On the other hand, the RT2 state is ended by winning one of the three-choice cherry roles.

  After the RT game state end process S615, a game progress display process S616 is executed. In the game progress display process S616, when the internal state is a big bonus or a regular bonus, data to be displayed on the game progress display device 116 such as the remaining number of games in the JAC game and the total number of medals obtained in one big bonus is displayed. Is set. Thereby, the game progress display device 116 displays the game progress information. When the internal state is the normal game state, the game progress display device 116 is in an off state and displays nothing.

  A control process executed by the MPU of the sub control board 302 will now be described. The MPU control process is roughly divided into a main process that is activated when the external power is restored from a power failure or when the power is turned on, and an interrupt process that interrupts the main process. For convenience of explanation, after describing the interrupt process, the main process will be described. As an interrupt process in the MPU, there are a periodic timer interrupt process and a command interrupt process executed in response to reception of a command from the main control board 301.

  The timer interrupt process is executed with a period of approximately 1 ms. In the timer interrupt process, first, an interrupt flag is read (interrupt flag read process). After the interrupt flag reading process, it is determined whether or not the interrupt flag is valid. Specifically, it is confirmed that it is a timer interrupt among various interrupts to the CPU. If the interrupt flag is valid, the interrupt timer counter is incremented and the interrupt timer counter is updated (interrupt timer counter update process). After the interrupt timer counter update process, the interrupt flag related to the timer interrupt is canceled (interrupt flag clear process). As a result, the next timer interrupt process for the CPU of the sub-control board 302 can be executed. If it is determined that the interrupt flag is not valid, the interrupt timer counter update process and the interrupt flag clear process are skipped because other interrupt processes are performed.

  The command interrupt process will be described in detail with reference to FIG. FIG. 20 is a flowchart showing command interrupt processing in the sub-control board 302. The command interruption process is executed in response to the transmission of a command from the main control board 301.

  In the command interruption process, first, it is determined whether or not the strobe signal from the main control board 301 is normal (S2101). If the strobe signal is normal, command data (communication header information) is acquired (command data acquisition processing S2102). After the command data acquisition process S2102, it is determined whether or not the content is normal (S2103). When the command data is normal, the communication information including the command converted in the port output process S213 (see FIGS. 8 and 10) of the main control board 301 is received (command reception process S2104), and the command reception process S2104 is received. After that, the retry counter value is changed to a predetermined maximum retry value (retry counter value maximizing process S2105).

  If it is determined in step S2101 that the strobe signal is not normal, the retry counter value is changed to a predetermined maximum retry number (S2106). If it is determined in the determination process S2103 that the command data is not normal, the retry counter value is changed (retry counter update process S2107). In this change, the retry counter value is increased by one. After the process of changing the retry counter value (S2105, S2106, S2107), it is determined whether the retry counter value is the maximum value (S2108). When the retry counter value is the maximum value, an interrupt flag is read (interrupt flag reading process S2109). After the interrupt flag reading process S2109, the value of the retry counter is cleared to the initial value (“0”) (retry counter clear process S2110). After the retry counter clear process S2110, the interrupt flag is canceled (interrupt flag clear process S2111). By releasing the interrupt flag, the next command interrupt process can be executed.

  When the retry counter value is not the maximum value, that is, when the strobe signal is normal but the command data is not normal, the interrupt flag reading process S2109, the retry counter clear process S2110, and the interrupt flag clear process S2111 are skipped. Note that acquisition of command data at a predetermined timing is repeated until the retry counter value reaches a predetermined maximum retry value.

  Here, the command reception process S2104 will be described with reference to FIG. FIG. 21 is a flowchart showing the command reception process S2104. In the command reception process S2104, the communication information sequentially transmitted from the main control board 301 to the input port is stored in a predetermined area of the RAM (communication information storage process S2601). Next, conversion initial information is extracted from the information of the first word of the received communication information (conversion initial information extraction processing S2602). A linear feedback shift operation corresponding to 16 bits is performed on the conversion initial information extracted from the communication information to generate first conversion information (conversion information update processing S2603), and the second word of the received communication information command An exclusive OR operation of the information and the first conversion information is executed to convert the information of the second word (upper word conversion processing S2604). Thereby, the information of the upper word of the command is extracted. The first conversion information is subjected to the same linear feedback shift operation corresponding to 16 bits as the conversion information update processing S2603 to generate second conversion information (conversion information update processing S2605), and the received communication information command The third word information is converted by executing an exclusive OR operation between the third word information and the second conversion information (lower word conversion processing S2606). As a result, the information of the lower word of the command is extracted, and the command to the sub control board 302 is a command of 2 words (32 bits), so that the entire command is also extracted. The command conversion mode and transmission mode will be described again in detail in the description of the characteristic part.

  The main process executed by the MPU of the sub control board 302 will be described in detail with reference to FIG. FIG. 22 is a flowchart showing an example of the main process of the sub control board.

  In the main processing, first, in accordance with the supply of internal power from the power supply board 300, initialization of the sub control board 302 itself and initialization of peripheral devices such as the auxiliary display device 118 connected to the sub control board 302 are performed. (Initialization processing S2201). After the initialization process S2201, it is determined whether or not the system state is a voltage drop state (S2202). Here, the system state includes a voltage drop state indicating that the supply voltage is equal to or lower than a predetermined voltage, and an initialization indicating that the sub-control board 302 and the peripheral device connected to the sub-control board 302 are being initialized. It implies a state and a normal state indicating that the supply voltage is a predetermined voltage and normal game can be performed. Note that the initialization state is selected during the initialization process S2201.

  When it is determined in the determination process S2202 that the system state is a voltage drop state, a backup process S2210 described later is executed. On the other hand, if the system state is not a voltage drop state, it is determined whether or not the value of the interrupt timer counter has changed (S2203). When there is a change in the value of the interrupt timer counter, the interrupt timer counter is updated (interrupt timer counter update process S2204). In the interrupt timer counter update process S2204, the value of the interrupt timer counter is decreased by 1. After the interrupt timer counter update process S2204, a short cycle timer process S2205 described later is performed. After the short cycle timer process S2205, it is determined whether or not the system state is a voltage drop state (S2206). If the system state is not a voltage drop state, it is determined whether any command is received from the main control board 301 (S2207). When a command is received, a received command confirmation process S2208 is performed in which the type of the received command is confirmed, and the notification mode is selected according to the type of command. On the other hand, if a command has not been received, the received command confirmation process S2208 is skipped. After the reception command confirmation process S2208, the base value of the random number that determines the details of the effect is updated (random number base value update process S2209). After the random number base value update process S2209, the process proceeds to a determination process S2202. When the system state is not a voltage drop state, the above processes (S2202 to S2209) are repeatedly executed in sequence.

  If it is determined in the determination processing S2202 and determination processing S2206 that the system state is a voltage drop state, register data and stack data are stored in the external RAM (backup processing S2210). After the backup process S2210, it is determined whether or not the system state is a voltage drop state (S2211). If the system state is a voltage drop state, the determination process S2211 is repeatedly executed. On the other hand, if the voltage drop state is not established, the system waits for a predetermined time (30 ms in this embodiment) to confirm that the cancellation of the voltage drop state is not a malfunction due to noise or the like (wait process S2212). After the wait process S2212, it is determined again whether the system state is a voltage drop state (S2213). If the system state is a voltage drop state, the process returns to the determination process S2211. On the other hand, if the system state is not a voltage drop state, it is determined that the supply of internal power has resumed normally, and a process for starting the main process is performed (start-up process S2214). After the startup process S2214, the process returns to the initialization process S2201, and the main process is resumed.

  The short cycle timer process S2205 in the main process of the sub-control board 302 will be described in detail with reference to FIGS. FIG. 23 is a flowchart showing the short cycle timer process. FIG. 24 is a flowchart showing the long cycle timer process executed during the short cycle timer process.

  By executing the timer interrupt process substantially every 1 ms, the short cycle timer process S2205 is also executed substantially every 1 ms. In the short cycle timer process 2205, as shown in FIG. 23, first, a startup command confirmation process S2301 is executed. In the startup command confirmation process S2301, it is confirmed whether any command is received from the main control board 301 within 2 seconds after the execution of the startup process S2214. When no command is received from the main control board 301, it is determined that the main control board 301 has not been normally activated, and processing for notifying the occurrence of an error is performed. On the other hand, if any command is received from the main control board 301, this process is terminated and the process proceeds to the device control process S2302.

  In the device control process S2302, the auxiliary display device 118, the acoustic device 110, and the light emitting device 117 are based on the data accumulated in the output data buffer in accordance with the various commands confirmed to be received in the reception command confirmation processing S2208. The drive control is performed. Specifically, display control signals such as an effect display control signal for instructing output of effect display and an error display control signal for instructing output of error display are transmitted to the auxiliary display device 118. Also, voice control signals such as a production voice control signal for instructing the sound device 110 to output production voice, an error voice control signal for instructing output of error voice, and a settlement voice control signal for supporting the output of the settlement voice; A volume control signal such as an effect volume control signal for instructing an effect volume, an error volume control signal for instructing an error volume, and a settlement volume control signal for instructing a settlement volume is transmitted. Further, a light emission control signal such as an effect light control signal for instructing output of effect light, an error light emission control signal for instructing output of error light, and a payment light emission control signal for instructing output of adjustment light to the light emitting device 117. Sent.

  In the system state change process S2303, it is determined whether or not there is a change in the system state, and the voltage drop flag indicating the voltage drop state and the in-initialization flag indicating the initialization state are set or canceled according to the determination result. . If there is a change in the system state, processing corresponding to the change is executed. When the voltage drop flag and the initialization flag are canceled, the system state is considered to be a normal state, and this process ends. The medal settlement process S2304 is executed after the system state change process S2303.

  In the medal settlement process S2304, when a settlement flag such as a credit settlement flag indicating that a credit medal is being settled or a bet settlement flag indicating that a bet medal is being settled is set, a notification mode is determined. Note that the credit settlement flag is set in response to reception of a credit settlement start command in the reception command confirmation process S2208, and is canceled in response to reception of a credit settlement end command. Similarly, the bet settlement flag is set in response to reception of a bet settlement start command, and is canceled in response to reception of a bet settlement end command.

  After the medal settlement process S2304, the demotion avoidance privilege number A and the demotion avoidance privilege number B are updated (demotion avoidance privilege management process S2305). Specifically, in the demotion avoidance privilege management process S2305, whether or not to grant the demotion avoidance privilege is determined by lottery when the watermelon role is won in the normal gaming state, and if this lottery is won, Demotion avoidance privilege number A increases by “1”. On the other hand, when the demotion avoidance privilege is used, the demotion avoidance privilege number A is decreased by “1”. Further, the demotion avoidance privilege number B is increased by “1” when the 3-option cherry combination wins in the big bonus game state. On the other hand, when the demotion avoidance privilege is used, the number B of demotion avoidance privilege decreases by “1”.

  After the demotion avoidance privilege management process S2305, in accordance with the winning of the first big bonus combination and the second big bonus combination, the big bonus gaming state 1 (BB gaming state 1: refer to FIG. 27) and the big bonus gaming state in advance. After the 2, the state of the RT gaming state 1 or the RT gaming state 2 (see FIG. 27), the ART gaming state B1 when the RT gaming state 1 and the RT gaming state 2 meet the promotion condition to the AT2 state Which of -ART gaming state B3 is to be transferred is determined by lottery (transfer destination allocation lottery processing S2306). Specifically, by electronic lottery, the first specified number of times A corresponding to the RT gaming state 1 or the second specified number of times B corresponding to the RT gaming state 2 is changed to the ART gaming state B1 to the ART gaming state B3. It is selected as the specified number of promotion conditions, and the first specified number of times B1 to B3 corresponding to the first gaming number B1 to the ART gaming state B3 corresponding to the ART gaming state B1 to the ART gaming state B3. Is selected as the number of continuous games in the ART game state B1 to the ART game state B3. In the transfer destination allocation lottery process S2306, there is no particular difference in the transfer destination allocation probability between the first big bonus combination and the second big bonus combination.

  Information for assisting the winning of the three-choice bell role while notifying the AT1 state for notifying the information for assisting the winning of the three-choice bell role and the information for avoiding the winning of the three-choice cherry role after the transfer destination lottery process S2306 In the AT2 state, the notification control process is executed based on the winning of the special replay combination in the AT1 state (AT state process S2307). Specifically, in the AT state processing S2307, the AT1 state is terminated based on detection of reception of an internal state command representing the normal gaming state from the main control board 301 in the AT1 state (ART gaming state A). This internal state command is transmitted based on the transition determination from the RT1 state to the normal gaming state in the RT gaming state end process S615 of the main control board 301. In the AT1 state, when a special avoidance bonus for a special replay role is available and the push order notification flag indicating that the bet operation unit 213 has been pressed is set, six special types A process for changing the special replay role winning information indicating that one of the replay roles and the normal replay role are won simultaneously to push order information for avoiding the special replay role winning and causing the normal replay role to win. Is executed. The push order notification flag is set in privilege use command processing S2520 described later.

  On the other hand, the AT2 state (ART game states B1 to B3) ends when the specified number of unit games determined in the transfer destination allocation lottery process S2306 is ended. In the RT gaming state end process S615 on the main control board 301, it is not determined that the RT1 state is ended. As a result, the RT gaming state 1 or the RT gaming state 2 is restored. In the present embodiment, the same RT gaming state as the previous time is selected as the RT game state of the transfer destination, and when the transition is made again to the ART game states B1 to B3, The same ART gaming state is selected.

  After the AT state processing S2307, it is determined whether or not to shift to the AT1 state and the AT2 state (AT state start determination processing S2308). Specifically, in the AT state start determination processing S2308, an internal state command representing the AT1 state transmitted from the main control board 301 in response to the transition to the RT1 state accompanying the end of the regular bonus gaming state (see FIG. 27). Based on the detection of reception, the sub-control board 302 is also shifted to the AT1 state. This results in an ART gaming state A (see FIG. 27) in which the RT1 state and the AT1 state are combined. Further, in the RT2 state accompanying the end of the big bonus game state (see FIG. 27), the main control is performed in accordance with the transition to the AT2 state accompanying the end of the prescribed number of unit games in the state where the 3-choice cherry combination is not winning. Based on detection of reception of an internal state command indicating the AT2 state transmitted from the substrate 301, the sub-control substrate 302 is also shifted to the AT2 state. As a result, an ART gaming state B (see FIG. 27) in which the RT2 state and the AT2 state are combined. It should be noted that if the three-choice cherry combination wins before the end of the predetermined number of unit games, the AT1 state is not shifted. In addition, in the RT gaming state 1 (see FIG. 27) and the RT gaming state 2 (see FIG. 27) that are in the RT2 state but not the AT2 state, a winning avoidance benefit for the cherry role can be used and the bet operation unit 213 is used. When the established combination notification flag indicating that the button has been pressed is set, the three-choice cherry role winning information indicating that one of the three-choice cherry roles has been won is changed to information of the winning cherry role. Processing for this is executed. The winning combination notification flag is set in privilege use command processing S2520 described later.

  In the voltage monitoring process S2309, it is determined whether or not the voltage of the internal power supplied from the power supply board 300 is equal to or lower than a predetermined voltage. If the internal voltage is equal to or lower than the predetermined voltage, the voltage drop flag is canceled. If the voltage drop flag is set, the voltage drop flag is canceled when the internal voltage is not lower than the predetermined voltage. After the voltage monitoring process S2309, a long cycle timer process S2310 described later is executed.

  After the long cycle timer processing S2310, data for controlling the auxiliary display device 118, the acoustic device 110, the light emitting device 117, and the like is updated (notification data change processing S2311). In the notification data change processing, display data for causing the auxiliary display device 118 to perform error display notification, effect display notification, and adjustment display notification, and the sound device 110 to perform error sound notification, effect sound notification, and adjustment sound notification. The acoustic data (volume data and audio data) is updated, and the updated display data and acoustic data are stored in the output data buffer.

  Here, the long cycle timer process S2310 will be described in detail. In the long cycle timer processing S2310, as shown in FIG. 24, the value of the short cycle timer counter is added to the value of the long cycle timer counter, and the long cycle timer counter is updated (long cycle timer counter addition processing S2401). . After the long cycle timer counter addition process S2401, it is determined whether or not the value of the long cycle timer counter is 10 or more (S2402). By the determination process S2402, the following process is executed approximately every 10 updates of the short cycle timer counter. Since the short cycle timer counter is updated approximately every 1 ms, the following processing is performed approximately every 10 ms.

  If it is determined in the determination process 2402 that the value of the long cycle timer counter is less than 10, this process ends. On the other hand, when the value of the long cycle timer counter is 10 or more, the value of the long cycle timer counter is decreased by 10, and the value of the long cycle timer counter is updated (long cycle timer counter subtraction process S2403). After the long-period timer counter subtraction process S2403, data of a desired light emission pattern is extracted from a light emission data table including a plurality of light emission patterns for various light emitting devices (light emitting device 117 and the like) held in the ROM of the sub control board 302. The data is stored in the output data buffer (light emission pattern data update process S2404). The stored data is output by the device control process S2302 in the short cycle timer process S2205.

  After the light emission pattern data update process S2404, a process for synchronizing the light emission effect and the sound effect is executed (light emission / sound synchronization process S2405). After the light emission / acoustic synchronization process S2405, in a situation where an audio effect is being performed, if the player is left unattended for a predetermined time (in this embodiment, 30 seconds) without any input. The sound production volume is changed to a low volume (acoustic fade-out process S2406). Further, without any input by the player, it is confirmed whether or not a predetermined time (in this embodiment, 50 seconds) has passed, and a demonstration flag is set (demonstration start confirmation processing S2407). Note that a predetermined demonstration demonstration effect is started on the auxiliary display device 118 by setting the demonstration flag. After the demonstration start confirmation process S2407, the volume setting of the volume adjustment switch (not shown) in the volume changing operation device (not shown) is confirmed, and the reference for the error notification, the settlement notification, and the production to the sound device 110 is confirmed. The volume is updated (volume setting processing S2408). Through the above process (long cycle timer counter addition processing S2401 to volume setting processing S2408), the long cycle timer processing S2310 ends.

  The received command confirmation processing S2208 (see FIG. 22) will be described in detail with reference to FIGS. 25 and 26 are flowcharts showing an example of the received command confirmation process S2208.

  Here, the playability of the slot machine 100 will be briefly described. FIG. 27 is a block diagram conceptually showing game state transition accompanying game progress.

  As shown in FIG. 27, when a regular bonus combination ([yellow 7 symbol / yellow 7 symbol / yellow 7 symbol]) is won in the normal gaming state, the gaming state is changed from the normal gaming state to the regular bonus gaming state (in the figure). (RB gaming state). After that, when the regular bonus gaming state ends, the RT1 state where only the winning probability of the replay role is higher than the normal gaming state, and any of the bell roles in the case of winning the 3 choice bell role Whether or not the auxiliary display device 118 or the like is completely notified of the AT1 state shifts to the ART gaming state A. Here, “three-choice bell role” means red bell role [red 7 symbol, bell symbol, bell symbol], blue bell role [blue 7 symbol, bell symbol, bell symbol], yellow bell role [yellow 7 symbol, Bell design, bell design] means a total of three types of bell roles, and three types of bell roles are won at the same time, and one type of bell role always wins. When the special replay role [replay role symbol, bell symbol, replay role symbol] is won in the ART game state A or when the unit game of the prescribed number of times A (for example, 100) is finished, the RT1 state and the AT1 state are finished. The gaming state shifts from the ART gaming state A to the normal gaming state.

  Also, in the normal gaming state, the first big bonus combination ([red 7 symbol / red 7 symbol / red 7 symbol]) and the second big bonus combination ([blue 7 symbol-blue 7 symbol-blue 7 symbol]) are won. Then, a transition is made to the big bonus gaming state 1 (BB gaming state 1 in the figure) and the big bonus gaming state 2 (BB gaming state 2 in the figure). The big bonus gaming state 1 and the big bonus gaming state 2 are substantially the same gaming state. When the big bonus gaming state 1 or the big bonus gaming state 2 ends, the gaming state shifts to the RT gaming state 1 or the RT gaming state 2 which is the RT2 state in which only the winning probability of the replay role is higher than the normal gaming state. To do. It should be noted that whether the RT gaming state 1 or the RT gaming state 2 is shifted to is determined by lottery when the first big bonus combination and the second big bonus combination are won. The RT game state 1 and the RT game state 2 have the same expected payout number per unit game. In the RT gaming state 1 and the RT gaming state 2, 3 choices that are incomplete winning combinations before the end of the unit game of the first specified number of times (for example, 30 times) and the second specified number of times (for example, 50 times), respectively. Cherry (Red cherry [Red cherry symbol, *, *], Blue cherry [Blue cherry symbol, *, *], Yellow cherry [Yellow cherry, *, *]; * means any symbol If any of the cherry roles won, the RT2 state is terminated and the gaming state shifts from the RT gaming state 1 to 2 to the normal gaming state. On the other hand, in the RT gaming state 1 and the RT gaming state 2, when the first specified number of times and the second specified number of unit games are completed without winning any of the three-choice cherry roles, Then, the state transitions to the ART gaming state B1, the ART gaming state B2, or the ART gaming state B3 in which the AT state is duplicated in the RT2 state. Note that which of the three types of ART gaming states B1 to B3 is to be shifted to is determined in advance by lottery when the first big bonus combination and the second big bonus combination are won. The RT game state 1 and the RT game state 2 have the same expected payout number per unit game, but the probabilities of promotion to any one of the three types of ART game states B1 to B3 are different depending on the specified number of times. Is different.

  In each of the ART gaming state B1, the ART gaming state B2, and the ART gaming state B3, as in the ART gaming state A, it is completely informed which of the three choice bells is won, and the normal bell When the winning combination and the special bell winning combination are won simultaneously, as shown in FIG. 28, information indicating the stop order of the reels 171L, 171M, 171R is notified on the auxiliary display device 118 or the like. When the reels 171L, 171M, and 171R are stopped in accordance with the notified stop order, the bell symbol is aligned with the middle line L1 that is not an effective line and a special bell role is won, which is different from the notified stop order. When the reels 171L, 171M, and 171R are stopped in order, the bell symbols are aligned on lines other than the middle line L1, and the normal bell combination with a smaller number of payouts than the special bell combination wins. In addition, when one of the three-choice cherry roles is won, in order to prevent the RT2 state from ending due to winning of the cherry role, which cherry role is won is completely notified. In the ART gaming state B1, the ART gaming state B2, and the ART gaming state B3, the first specified number of times B1 (for example, 50 times), the second specified number of times B2 (for example, 100 times), and the third specified number of times B3 ( When the unit game is completed (for example, 300 times), the AT2 state is ended, and the gaming state is changed from the ART gaming state B1 to B3 to the RT gaming state previously selected from the RT gaming state 1 and the RT gaming state 2. Transition. In the ART game states B1 to B3, the expected payout number per unit game is the same, but the expected payout number per transition to the ART game state differs depending on the difference in the specified number of times. Although not shown in FIG. 27, in each of the ART gaming state B1, the ART gaming state B2, and the ART gaming state B3, although the winning of the cherry role can be prevented by the complete notification of the winning cherry role, If the cherry role is won by mistake, the RT state 2 is ended and the state is simply the AT2 state, and then the normal game state is entered in accordance with the end of the AT2 state with the end of the predetermined number of unit games. To do.

(Configuration of features of the present invention)
An information transmission mode between the main control board 301 and the sub control board 302, which is a main characteristic part of the present invention, and a configuration related thereto will be described in detail.

  As described above, the slot machine 100 controls the audio device 110, the light emitting device 117, and the auxiliary display device 118 based on a main control board 301 that controls the slot machine 100 in an integrated manner and commands from the main control board 301. (See FIG. 10), each of the main control board 301 and the sub control board 302 is a backup capable of maintaining internal information for a certain period (about one week) even after the power is turned off. It has a function.

  Further, in the slot machine 100, as described above, the acoustic device 110, the light emitting device 117, and the auxiliary display device 118 notify the stop order of the left reel 171L, the middle reel 171M, and the right reel 171R as a gaming state. The AT state (AT1 state and AT2 state) that supports winning of the winning combination is included, and the transition to the AT state (see FIGS. 28 and 27) is determined by the main control board 301 (RT gaming state end processing S615). Based on the AT1 state command or AT2 state command (a kind of internal state command) from the main control board 301, control corresponding to the AT1 state or AT2 state is also started in the sub control board 302 (AT state start determination processing) S2308), notification for supporting winning in AT state and management of continuation of AT state Is performed independently in the sub-control board 302 (in AT state process S2307). Therefore, the command transmitted from the main control board 301 to the sub control board 302 includes a command that affects medal acquisition.

  Each of the main control board 301 and the sub control board 302 operates with 16 bits as unit operation control bits. Various information is transmitted between the main control board 301 and the sub control board 302 using 16 bits as a unit communication control bit. Since various commands transmitted from the main control board 301 to the sub-control board 302 are commands of 2 words (32 bits), word data can be continuously transmitted in a plurality of times in one information transmission. It will be received. In addition, various commands transmitted from the main control board 301 to the sub control board 302 are transmitted in a state in which predetermined conversion is performed on the commands, not the information itself corresponding to the commands.

  Hereinafter, a transmission mode from the main control board 301 to the sub control board 302 will be described in detail with reference to FIGS. 29 to 32. FIG. 29 is an explanatory diagram illustrating a conceptual generation mode of conversion information generated for converting a command in the main control board and the sub control board, and FIG. 30 illustrates a specific generation mode of conversion information. FIG. 31 is a schematic explanatory diagram showing a command conversion mode on the main control board 301, and FIG. 32 is a schematic description showing a command extraction mode on the sub control board 302. FIG.

  When it is necessary for the main control board 301 to transmit a command to the sub control board 302, the command is identified by the generator polynomial shown in FIG. 29A from the converted initial information. Is subjected to a predetermined conversion based on two pieces of conversion information generated by the bit operation shown below (hereinafter referred to as “linear feedback shift operation”), and the converted command is transmitted to the sub-control board 302. It becomes. Further, when the sub-control board 302 receives the command after conversion, the sub-control board 302 receives predetermined information based on two pieces of conversion information generated by the same information as the initial conversion information in the main control board 301 and the same calculation as the linear feedback shift calculation. After the conversion, the converted command is returned to the pre-conversion command on the main control board 301.

  Specifically, as shown in FIG. 31, in the first command communication after the start of power supply, a unique ID is acquired from the CPU 311 and set as conversion initial information R (1) (conversion initial information acquisition). Process S1003: Refer to FIG. 10), first conversion information R (2) is generated by linear feedback shift calculation with respect to the conversion initial information R (1) (conversion information update process S1004: refer to FIG. 10). Second conversion information R (3) is generated by a linear feedback shift operation on R (2) (conversion information update processing S1006: see FIG. 10).

  First, how the first conversion information and the second conversion information are generated will be described. In the linear feedback shift calculation shown in FIG. 29B, the value of the 0th bit (D0) before the calculation is changed to a new value of the 15th bit (D15), and the first bit (D1) to the first bit before the calculation are calculated. The value of 10 bits (D10) is shifted right by 1 bit to obtain new values of the 0th bit (D0) to the 9th bit (D9), the 11th bit (D4) before the calculation and the 0th bit before the calculation. The value of the exclusive OR with the bit (D0) is set as a new value of the 10th bit (D10), and the value of the 12th bit (D11) before the operation is shifted right by 1 bit to return to the 11th bit (D12) And the XOR value of the 13th bit (D10) before the operation and the 0th bit (D0) before the operation is set as the new value of the 12th bit (D9). The exclusive OR of 14 bits (D11) and 0th bit (D0) before the operation Was a new value of the 13-bit (D10), it is an operation to a new value of the value of the 15 bits before operation (D11) is right shifted by 1 bit bit 14 (D10). As a result, with respect to the value before the operation shown in FIG. 30A, the value after the operation is when the value (“a”) of the 0th bit (D0) before the operation is “0”. When the value (“a”) of the 0th bit (D0) before the calculation is “1”, as shown in FIG. Becomes the indicated value. In FIG. 30, each of “a” to “i” is “0” or “1”, and each of “a” to “i” to which a horizontal bar is attached represents an inverted value thereof.

  As shown in FIG. 30B, if the value (“a”) of the 0th bit (D0) in the value before the calculation is “0”, the value after the calculation is the same as the value before the calculation. This value is the same as the value in parentheses representing the case where a single right shift operation is performed by bit-shifting to the right by a bit and setting the 15th bit (D15) to “0”. Further, as shown in FIG. 30C, if the value (“a”) of the 0th bit (D0) in the value before the calculation is “1”, the value after the calculation is the value before the calculation. Same as the value obtained by performing an exclusive OR operation between the value after the right shift operation for the first time (upper value in parentheses) and the tap value associated with the generator polynomial (lower value in parentheses) It is. The “tap value” is a value in which the value of the bit specified by the exponent part of each X in the generator polynomial is “1” and the value of the other bits is “0”. In the generator polynomial, the notation is the case where the least significant bit is the first bit, but in this embodiment, since the notation is used where the least significant bit is the 0th bit, the exponent of each X in the generator polynomial is used. The bit number specified in the part is shifted so as to increase by “1”.

If a linear feedback shift operation corresponding to the generator polynomial (X ¹⁶ + X ¹⁴ + X ¹³ + X ¹¹ +1) is repeated with a value other than “0” as an initial value, a value other than “0” (65535 [= 2 ¹⁶ −1) is performed. ]), A periodic random number sequence R that sequentially returns to the initial value without overlapping is generated.

  That is, if the value of the 0th bit of the conversion initial information R (1) is “0” with respect to the conversion initial information R (1), the CPU 311 performs the right shift operation prepared as a basic operation only once. If it is performed, the first conversion information R (2) is generated. On the other hand, if the value of the 0th bit of the conversion initial information is “1”, it is exclusive with the tap value after performing the right shift operation only once. If the logical sum is taken, the first conversion information R (2) is generated. Moreover, the 2nd conversion information R (3) is produced | generated by performing the same calculation with respect to 1st conversion information.

  Next, a command conversion mode based on the first conversion information R (2) and the second conversion information R (3) will be described. As shown in FIG. 31, the upper word CH is converted by taking the exclusive OR of the upper word CH (upper 16 bits) of the command and the first conversion information R (2), and the converted upper word CH− 1 (upper word conversion processing S1005: see FIG. 10), the lower word is converted and converted by taking the exclusive OR of the lower word CL (lower 16 bits) of the command and the second conversion information R (3). It becomes the lower word CL-2 (lower word conversion processing S1007: see FIG. 10). As a result, the entire command is converted. In the following, the converted command is also referred to as a conversion command.

  Next, a transmission mode for transmitting the conversion command to the sub control board 302 will be described. In the first command communication, communication information including the conversion initial information R (1) and the conversion command is transmitted to the sub control board 302 (abbreviated as “sub” in FIG. 31). Specifically, since the unit communication control bit is 16 bits, the conversion initial information R (1), the conversion high-order word CH-1 and the conversion low-order that make up the communication information follow the communication header information (not shown). The word CL-2 is continuously transmitted in this order (sub-communication information output process S1008: see FIG. 10). Through the above process, transmission in the first command communication is completed.

  In command communication after the first time, when a value is acquired from a random number counter that is a hardware counter mounted on the main control board 301 and used for determining a winning combination, and the acquired value is not “0”. Is set as conversion initial information R (i) (conversion initial information acquisition processing S1003: see FIG. 10). However, when the acquired value from the random number counter is “0”, the acquisition of the value from the random number counter is repeated until a value other than “0” is acquired. Thereby, in the command communication after the first time, a random value is set as the conversion initial information. Thereafter, similarly to the first command communication, the first conversion information R (i + 1) is generated by the linear feedback shift operation on the conversion initial information R (i) (conversion information update processing S1004: see FIG. 10), and the first conversion Second conversion information R (i + 2) is generated by a linear feedback shift operation on information R (i + 1) (conversion information update processing S1006: see FIG. 10). Also, the conversion upper word CH′−1 converted by the conversion initial information R (i) and the first conversion information R (i + 1) and the conversion lower word CL′-2 converted by the second conversion information R (i + 2) Communication information including is transmitted.

  In the above, for convenience of explanation, the conversion initial information R (1), R (i), the first conversion information R (2), R (i + 1) and the second conversion information R (3), R (i + 2) are individually set. Although it is described as if it is transmitted after the entire conversion of the command stored in the RAM 313 is performed, the conversion initial information stored in a predetermined area of the RAM 313 will be described along the time series. After the transmission of R (1), R (i) is started, the value of the predetermined area is rewritten to the first conversion information R (2), R (i + 1) and the first conversion information R (2), Conversion of the upper words CH and CH ′ of the command is executed based on R (i + 1). Then, after completion of transmission of the conversion initial information R (1) and R (i), transmission of the conversion upper words CH-1 and CH'-1 is started. Similarly, after the transmission of the first conversion information R (2) and R (i + 1) is started, the value of the predetermined area is rewritten to the second conversion information R (3) and R (i + 2) and the second Based on the conversion information R (3) and R (i + 2), the conversion of the lower words CL and CL ′ of the command is executed, and after the transmission of the first conversion information R (2) and R (i + 1) is completed, the lower conversion words Transmission of the words CL-1, CL'-1 is started.

  When the sub-control board 302 receives communication information including the conversion initial information R (i), the conversion upper word CH′−1 and the conversion lower word CL′−1 as shown in FIG. 32 (communication information storage). Process S2601: See FIG. 21), conversion initial information R (i) is extracted from communication information and set as conversion initial information R (i) (conversion initial information extraction process S2602: see FIG. 21), and conversion initial information R ( The first conversion information R (i + 1) is generated by the linear feedback shift operation for i) (conversion information update processing S2603: see FIG. 21), and further the second conversion is performed by the linear feedback shift operation for the first conversion information R (i + 1). Information R (i + 2) is generated (conversion information update processing S2605: see FIG. 10).

  Finally, a command conversion mode based on the first conversion information R (i + 1) and the second conversion information (i + 2) will be described. As shown in FIG. 32, the conversion upper word CH′−1 is converted by taking the exclusive OR of the conversion upper word CH′−1 and the first conversion information R (i + 1), and the upper word of the command is converted. CH ′ (upper word conversion processing S2604: see FIG. 21), and the converted lower word CL′−1 is converted by taking the exclusive OR of the converted lower word CL′−1 and the second conversion information R (i + 2). Thus, it becomes the lower word CL ′ of the command (lower word conversion processing S2606: see FIG. 21). As a result, the entire conversion command is reconverted and the command is extracted.

  In the above, for convenience of explanation, after the entire communication information is received, conversion initial information R (i), first conversion information R (i + 1), and second conversion information R (i + 2) are generated and stored in individual areas of the RAM 313. Although it is described as if the command is extracted after that, if it is described along the time series, when the conversion initial information (i) is received, the value of the predetermined area of the RAM 313 is rewritten. The first conversion information R (i + 1) is generated, the value of the predetermined area is further rewritten, and the reception of the conversion upper word CH′−1 is awaited. When the conversion high-order word CH′−1 is received, conversion of the conversion high-order word CH′−1 is executed based on the first conversion information R (i + 1) and the second conversion information R (i + 2) is generated to generate the predetermined conversion information. Is rewritten, and the reception of the converted lower word CL′−1 is awaited. Similarly, when the converted lower word CL'-1 is received, the conversion of the converted lower word CL'-1 of the command is executed based on the second conversion information R (i + 2).

  In the case of the slot machine 100 described above, since the information of the command itself transmitted from the main control board 301 to the sub control board 302 is not transmitted / received, communication transmitted from the main control board 301 to the sub control board 302 is performed. It becomes difficult to identify various commands from information, and various commands can be transmitted safely. As a result, a command that makes the player advantageous in terms of payout of medals, such as AT1 status command and AT2 status command, is illegally transmitted to the sub-control board 302, and the game is advantageously advanced to excessively receive medals. It can also suppress fraudulent activities that can be acquired. For this reason, commands that are not desired to be known by criminals, including commands for making the player advantageous, etc., can be converted into commands that combine different values for each communication and communicated.

  In the case of the slot machine 100, various commands transmitted from the main control board 301 to the sub control board 302 are dividedly converted based on the two pieces of conversion information, so that various commands are identified from the communication information. It becomes even more difficult to do. In addition, since the two conversion information is generated to different values based on the common conversion initial information, the amount of data required for command communication is suppressed, and the conversion source command is converted in a complicated manner for illegal purposes. Can be difficult to analyze.

  In the case of the slot machine 100, since the first conversion information and the second conversion information itself necessary for extracting the command before conversion from the conversion command are not transmitted / received, various conversion information is converted into the conversion command. Various commands can be transmitted safely compared to the case of transmitting together.

  Further, in the case of the slot machine 100, since the unique ID of the CPU 311 is used as the initial conversion information for the first command communication, the random number counter is not started when the main control board 301 is started up. Can send commands. Furthermore, since “0” is not normally set as the unique ID of the CPU 311, the CPU 311 surely functions as conversion initial information. In addition, since the conversion information is generated using the unique ID of the CPU 311, a common command can be converted into a different command and communicated even with the same model of the same manufacturer. For this reason, for example, the same command transmitted from a plurality of slot machines 100 such as a large number of slot machines 100 installed adjacent to each other can be converted into different commands and communicated.

  In the case of the slot machine 100, bit calculation is performed in the generation of various types of conversion information in the main control board 301 and the sub control board 302, the conversion of commands in the main control board 301, and the conversion commands in the sub control board 302. Therefore, the calculation can be performed at a very high speed as compared with the case of performing operations other than bit operations such as addition / subtraction / multiplication / division operations, and the transmission of commands on the main control board 301 and the reception of conversion commands on the sub control board 302 can be performed. The delay can be suppressed very well.

[Embodiment 2]
The slot machine of the second embodiment is configured such that the initial conversion information for two consecutive information communications is set at random in the information communication from the main control board 301 to the sub control board 302 by the slot machine 100 of the first embodiment. In contrast, the conversion initial information for two consecutive information communications has a predetermined relationship.

  In the following description, components that are substantially the same as those of the slot machine 100 are denoted by the same reference numerals, and redundant description is omitted. Differences from the slot machine 100 will be described in detail with reference to FIGS. 33 to 38. explain. FIGS. 33 and 34 are flowcharts showing main control main processing and port output processing, respectively. FIGS. 35 and 36 are command conversions in the first command communication after the start of power supply with initialization, respectively. FIG. 37 and FIG. 38 are explanatory diagrams showing command conversion modes and extraction modes in the first command communication after the start of power supply without initialization, respectively.

  In the slot machine of the second embodiment, as compared with the slot machine 100 of the first embodiment, the conversion initial information setting process is performed after the probability setting selection process S406 in the main process of the main control board 301 as shown in FIG. S418 and initialization command setting processing S419 are newly executed. In the conversion initial information setting process S418, the unique ID of the CPU 311 is acquired and set as conversion initial information. In the initialization command setting process S419, the conversion initial information is transmitted to the sub-control board 302 in order to transmit the conversion initial information. An initialization command (one word command) including initial information is set. Also, a port output process S213 'shown in FIG. 34 is executed instead of the port output process S213 of the slot machine 100 of the first embodiment. In the port output process S213 ′, a determination process S1009 for newly determining whether the command to the sub-control board 302 is 2 words or 1 word is newly executed, and the conversion initial stage in the port output process S213 of the first embodiment is performed. The information acquisition process S1003 (see FIG. 10) is not executed. As a result of these changes, the 2-word command is converted by various conversion information generated from the conversion initial information as in the first embodiment and transmitted to the sub-control board 302. Are transmitted to the sub-control board 302 without being converted.

  When the probability setting is changed and the information stored in the RAM is initialized, the conversion initial information is transmitted to the sub-control board 302 only once. If the command to the sub-control board 302 is a 2-word command, the converted command is transmitted as in the first embodiment. If the command is a 1-word command, various conversions are performed. Sent without being converted by information.

  Here, the transmission mode from the main control board 301 to the sub control board 302 will be described in order when initialization and setting change are performed at the start of power supply and when they are not performed.

  First, supply of power to the slot machine is started, and various information in the backed-up RAM 313 is initialized and the probability setting is changed on the main control board 301 (S404: Y, forced RAM clear) Process S405, probability setting selection process S406), and as shown in FIGS. 35 and 36, the unique ID is acquired from the CPU 311 and set as conversion initial information R (1) (conversion initial information setting process S418: FIG. 33). Thereafter, the conversion initial information R (1) is transmitted following the transmission header (not shown) for one word (S1009: N, S1008).

  First, at the start of power supply, in the first two-word command communication after the start of power supply, the first conversion information R (2) is converted from the conversion initial information R (1) by the linear feedback shift operation, as in the first embodiment. ) And second conversion information R (3) are generated, and the upper word CH and the lower word CL of the command are converted by the first conversion information R (2) and the second conversion information R (3). Then, the converted upper word CH-1 and the converted lower word CL-1 are transmitted to the sub-control board 302 following the transmission header for 2 words. Unlike the case of the first embodiment, the conversion initial information R (1) has been transmitted in advance and is not transmitted together with the conversion upper word CH-1 and the conversion lower word CL-1.

  In the second two-word command communication, as shown in FIG. 35, a linear feedback shift operation is performed on the second conversion information R (3) for the first two-word command communication, and the second two-word command communication is performed. First conversion information R (4) for word command communication is generated, and linear feedback shift operation is performed on the first conversion information R (4) to generate second conversion information R (5). Similarly to the case of the first embodiment, the upper word CH ′ and the lower word CL ′ of the command are converted by the first conversion information R (4) and the second conversion information R (5), and the conversion upper word CH′− 1 and the converted lower word CL′−1 are transmitted to the sub-control board 302.

  In the sub control board 302, as shown in FIG. 36, the conversion initial information R (1) transmitted from the main control board 301 with the start of power supply is stored. In the first two-word command communication, a linear feedback shift operation is performed on the conversion initial information R (1) transmitted in advance to generate the first conversion information R (2) for the first two-word command communication. And a linear feedback shift operation is performed on the first conversion information R (2) to generate second conversion information R (3). Thereafter, as in the case of the first embodiment, the conversion upper word CH′−1 and the conversion lower word transmitted from the main control board 301 by the first conversion information R (2) and the second conversion information R (3). CL'-1 is converted by the first conversion information R (2) and the second conversion information R (3), and the conversion upper word CH-1 and the conversion lower word CL-1 of the command are extracted. In the first two-word command communication, as in the case of the main control board 301, the linear feedback shift operation is performed on the second conversion information R (3) for the first two-word command communication, and the second two-word command communication is performed. The first conversion information R (4) for the command communication is generated and a linear feedback shift operation is performed on the first conversion information R (4) to generate the second conversion information R (5). Become.

  As described above, when initialization or setting change is performed at the start of power supply, the conversion initial information R (1) is only once in advance prior to the first two-word command communication from the main control board 301 to the sub-control board 302. Is transmitted, the conversion initial information is made common between the main control board 301 and the sub control board 302, and thereafter, various types of conversion information are individually generated by the main control board 301 and the sub control board 302. Will be controlled.

  If the supply of power to the slot machine is started and various information in the backed-up RAM 313 is not initialized and the probability setting is not changed in the main control board 301 (S404: N, forced RAM clear processing S405 and As shown in FIGS. 37 and 38, the second conversion information R (j) for the two-word command communication immediately before the previous power shutdown is the first time after the start of power supply. Used as conversion initial information for 2-word command communication. Note that the conversion initial information is not transmitted to the sub-control board 302.

  Also in the sub-control board 302, as shown in FIG. 37 and FIG. 38, the second conversion information R (j) for the two-word command communication immediately before the previous power shutdown is the first time after the start of power supply. Used as conversion initial information for 2-word command communication. The main control board 301 and the sub control board 302 operate in the same manner as when initialization or setting change is performed at the start of power supply, except that the conversion initial information setting mode is different.

  The slot machine of the second embodiment has the same effects as the slot machine 100 of the first embodiment. Furthermore, since various conversion information for each two-word command communication is independently managed by the main control board 301 and the sub control board 302, correct communication information is temporarily sent to the sub control board 302 from other than the main control board 301. Even if it is illegally transmitted, when the regular communication information is transmitted from the main control board 301, the sub-control board 302 cannot correctly extract the command from the communication information, and the command is illegally transmitted to the sub-control board 302. Can be detected.

  In the first embodiment described above, the configuration using the random number counter that determines the winning combination as the initial conversion information for each command communication has been described. However, other hardware counters, hardware timers, and the like mounted on the main control board 301 have been described. It is also possible to use a hardware counter or hardware timer incorporated in the MPU 310 or CPU 311, or to provide a new hardware counter or hardware timer to update the conversion initial information. it can.

  In the second embodiment, the configuration using the unique ID of the CPU 311 as the conversion initial information has been described. However, the conversion initial information may be set based on other internal information that differs for each slot machine. Alternatively, the conversion initial information may be set based on the value of the counter used so that the value changes substantially continuously. In addition, it is preferable that a different value is set for each individual slot machine, but a different value may be set for each individual slot machine.

  In the first embodiment and the second embodiment described above, the configuration in which a command obtained by performing a predetermined conversion on the command to the sub-control board 302 that assists production and winning is described. However, other control boards, for example, A command obtained by performing a predetermined conversion on a command such as a payout command or a lending command to a payout control board in a gaming machine having a payout control board for controlling the payout of game media such as medals may be transmitted. it can.

  In the first embodiment and the second embodiment described above, in the command communication of the swivel type gaming machine using a medal as a game medium, the configuration for transmitting a command subjected to a predetermined conversion has been described. However, a sphere is used as a game medium. It can also be set as the structure applied with respect to command communication in a revolving type game machine or a ball game machine. Furthermore, it may be configured to be applied to communication with a device capable of communicating with a gaming machine. For example, in a normal game, gaming media are not paid out to the outside of the gaming machine as in an enclosed ball game machine. There is a configuration that electronically increases or decreases the number of stored game balls, and a configuration that is applied to communication with a settlement apparatus that settles electronically stored game balls.

[Embodiment 3]
The slot machine of the third embodiment is configured such that the slot machine 100 of the first embodiment is generated by a fixed number of linear feedback shift operations with respect to the initial conversion information in the generation of the first conversion information and the second conversion information. Thus, the number of times of linear feedback shift calculation is dynamically changed based on a part of information of the initial conversion information.

  In the following description, components that are substantially the same as those of the slot machine 100 are denoted by the same reference numerals, and redundant description is omitted. Differences from the slot machine 100 will be described in detail with reference to FIGS. 39 and 40. explain. FIG. 39 is an explanatory diagram showing the conversion mode of the command, and FIG. 40 is an explanatory diagram showing the correlation between the conversion initial information, the first conversion information, the second conversion information, the conversion upper word, and the conversion lower word.

  The number of linear period shift operations for generating the first conversion information from the conversion initial information is changed based on the value of the 0th bit of the conversion initial information, and the conversion is performed based on the value of the first bit of the conversion initial information. The number of linear period shift operations for generating the first conversion information from the initial information is changed. Specifically, when the 0th bit of the conversion initial information is “0”, a value generated by one linear feedback shift operation on the conversion initial information as in the first embodiment. Becomes the first conversion information, and the 0th bit of the conversion initial information is “1”, the value generated by the two linear feedback shift operations for the conversion initial information is the first conversion information. Further, when the first bit of the conversion initial information is “0”, the value generated by one linear feedback shift operation for the first conversion information is the same as in the case of the first embodiment. When the first conversion information is “1”, the value generated by performing two linear feedback shift operations on the conversion initial information is the second conversion information.

  For example, when the lower 2 bits of the conversion initial information is “11”, as shown in FIG. 39, the value R (i + 1) generated by the linear feedback shift operation on the value R (i) of the conversion initial information. ), A value R (i + 2) is generated as the first conversion information. Further, the value R (i + 4) as the second conversion information is obtained by further performing the linear feedback shift operation on the value R (i + 3) generated by the linear feedback shift operation on the value R (i + 2) of the first conversion information. Is generated. Thereby, the conversion upper word CH′−2 in which the upper word CH ′ of the command is converted by the value R (i + 2) as the first conversion information, and the lower word of the command by the value R (i + 4) as the second conversion information Communication information including the converted lower-order word CL′-4 converted from CL ′ is transmitted from the main control board 301. In the sub control board 302 that has received the communication information, a value R (i + 2) as the first conversion information and a value R (i + 4) as the second conversion information are generated from the conversion initial information included in the communication information. The upper word of the command is restored from the converted higher word CH′−2 included in the communication information based on the value R (i + 2), and the converted higher word CH′−2 included in the communication information based on the value R (i + 4). The upper word of the command is restored.

  As shown in FIG. 40, when the lower 2 bits of the conversion initial information is “00”, as in the case of the first embodiment, as the first conversion information and the second conversion information, The converted upper word CH′−1 converted based on the value R (i + 1) and the converted lower word CH′−1 converted based on the value R (i + 1) and the converted lower word converted based on the value R (i + 2), respectively. Communication information including CL′-2 is transmitted. When the lower 2 bits of the conversion initial information are “01”, the value R (i + 2) and the value R (i + 3) are used as the first conversion information and the second conversion information, respectively, and the value R ( Communication information including the converted upper word CH′−2 converted based on i + 2) and the converted lower word CL′−3 converted based on the value R (i + 3) is transmitted. When the lower 2 bits are “10”, the value R (i + 1) and the value R (i + 3) are used as the first conversion information and the second conversion information, respectively, and the conversion is performed based on the value R (i + 1). Communication information including the converted upper word CH′−1 and the converted lower word CL′−3 converted based on the value R (i + 3) is transmitted.

  In the configuration of the third embodiment, the first conversion information or the conversion lower word for normally converting the conversion upper word from the conversion initial information included in the communication information into the upper word CH ′ of the command is used as the lower word CL of the command. Since it is more difficult to infer the second conversion information for normal conversion to 'than in the case of the first embodiment, various kinds of communication information are transmitted from the main control board 301 to the sub control board 302. It becomes more difficult to identify the command, and various commands can be transmitted more safely.

  In the third embodiment, the number of repetitions of the linear feedback shift calculation for generating the first conversion information based on the value of the 0th bit (least significant bit) of the conversion initial information is “1” or “2”. In addition, the case has been described in which the number of repetitions of the linear feedback shift operation for generating the second conversion information based on the value of the first bit of the conversion initial information is “1” or “2”. As long as the number of repetitions is different, another number of times can be set, and a bit to be referred to can be changed based on the value of another bit. In addition, when it is set as the structure which sets the frequency | count of repetition to the minimum frequency, the burden of the control process accompanying the production | generation of 1st conversion information and 2nd conversion information and the increase in time can be suppressed to the minimum. Further, an additional linear feedback shift operation is performed based on the value of the 0th bit (the leading bit on the shift side in the linear feedback shift operation) extracted as a carry bit in at least the linear feedback shift operation necessary for generating the conversion information. When the configuration is used to determine the necessity, the other calculation for deriving the value of the specific bit is unnecessary, and the linear for generating the conversion information based on the value of the bit other than the 0th bit. The control process can be simplified as compared with the case of determining the necessity of the feedback shift calculation.

  In the third embodiment, the configuration in which the number of repetitions of the linear feedback shift calculation is changed based on a part of information of the initial conversion information in the generation of both the first conversion information and the second conversion information has been described. However, the number of repetitions of the linear feedback shift operation can be changed for at least one of the generations.

  In the third embodiment, a case has been described in which a configuration in which the first conversion information and the second conversion information are dynamically changed based on part of the initial conversion information is applied to the first embodiment. However, it can also be applied to the second embodiment. However, when applied to the second embodiment, for the two-word command communication other than the first time, the “conversion initial information” and the identification character “i” are “second conversion information in the previous two-word command communication”, respectively. And the identification character “j”. In addition, in the configuration of the second embodiment, the difficulty of guessing the first conversion information and the second conversion information based on the interception of a plurality of two-word command communications is inferior to that of the first embodiment. It is more preferable to apply a configuration that dynamically changes the first conversion information and the second conversion information as in the third embodiment.

[Embodiment 4]
In the slot machine according to the fourth embodiment, the slot machine 100 according to the first embodiment generates the converted upper word only by the exclusive OR operation between the upper word of the command and the first conversion information, and the lower word of the command and the second conversion information. The conversion lower word is generated only by the exclusive OR operation with, while the bit array is further converted before or after the exclusive OR operation in the generation of the conversion upper word and the conversion lower word. In this configuration, the initial information is dynamically changed according to a part of bit information.

  In the following description, components that are substantially the same as those of the slot machine 100 are denoted by the same reference numerals, and redundant description is omitted. Differences from the slot machine 100 are described in detail with reference to FIGS. 41 and 42. explain. FIG. 41 is an explanatory diagram showing the conversion mode of the command, and FIG. 42 is a schematic diagram showing the correlation between the conversion initial information and the upper byte and lower byte of the conversion upper word and the upper byte and lower byte of the conversion lower word. It is explanatory drawing.

  In the slot machine of Embodiment 4, in the generation of the conversion upper word, after the exclusive OR operation of the upper word of the command and the first conversion information, the bit array of the information after the operation is converted to the 0th bit of the conversion initial information. And after the exclusive OR operation of the lower word of the command and the second conversion information, the bit array of the lower byte of the information after the operation is changed to the value of the first bit of the conversion initial information. Different depending on. Specifically, when the 0th bit of the conversion initial information is “1”, the upper byte and the lower byte of the value after the exclusive OR operation corresponding to the upper word of the command are replaced, and the conversion initial When the first bit of information is “1”, the upper byte and lower byte of the value after the exclusive OR operation corresponding to the lower word of the command are replaced. It should be noted that such replacement is not performed when the 0th bit or the 1st bit of the conversion initial information is “0”.

  For example, when the lower 2 bits of the conversion initial information is “11”, the 0th bit of the conversion initial information is “1” as shown in FIG. The value CHU ′ generated from the value CHU ′ of the upper byte of the upper word of the command by the exclusive OR operation of the upper word of the command (corresponding to the upper word CH ′ in FIG. 32) and the first conversion information R (i + 1). −1 is set as the value of the lower byte of the conversion upper word, and the value CHD′−1 generated from the value CHD ′ of the lower byte of the upper word of the command is set as the value of the upper byte of the conversion upper word. . In addition, since the first bit of the conversion initial information is “1”, the exclusive OR operation of the lower word of the command (corresponding to the lower word CL ′ in FIG. 32) and the second conversion information R (i + 2) is performed. The value CLU′−2 generated from the value CLU ′ of the upper byte of the lower word of the command is set as the value of the lower byte of the converted lower word and generated from the value CLD ′ of the lower byte of the lower word of the command The value CLD'-2 is set as the value of the upper byte of the converted lower word. On the other hand, in the sub control board 302, since the 0th bit of the conversion initial information included in the communication information from the main control board 301 is “1”, the upper byte (CHD′−) of the conversion upper word included in the communication information. 1) and the lower byte (CHU′−1) are replaced, and then an exclusive OR operation is performed on the first conversion information R (i + 1) to restore the upper word of the command. In addition, since the first bit of the conversion initial information is “1”, the upper byte (CLD′-2) and the lower byte (CLU′-2) of the conversion lower word included in the communication information are replaced. An exclusive OR operation with the second conversion information R (i + 2) is executed, and the lower word of the command is restored.

  As shown in FIG. 42, when the lower 2 bits of the conversion initial information are “00”, the upper word and lower word of the command are not replaced after the exclusive OR operation, and the conversion upper word The values of the upper byte and lower byte and the upper byte and lower byte of the converted lower word are “CHU′-1” and “CHD′-1”, “CLU′-2” and “CLD′-2”, respectively. The value is the same as that in the first embodiment. When the lower 2 bits of the conversion initial information are “01”, the upper word of the command is replaced after the exclusive OR operation, but the lower word of the command is not replaced after the exclusive OR operation. The values of the upper byte and lower byte of the upper word and the upper byte and lower byte of the converted lower word are “CHD′−1” and “CHU′−1”, “CLU′-2” and “CLD′-2”, respectively. When the lower 2 bits of the conversion initial information are “10”, the upper word of the command is not replaced after the exclusive OR operation, but the lower word of the command is replaced after the exclusive OR operation. The values are "CHU'-1" and "CHD'-1", and "CLD'-2" and "CLU'-2", respectively. As can be seen from FIG. 42, the combination of the upper byte and the lower byte of the converted upper word and the values of the upper byte and the lower byte of the converted lower word are all different. Even if the exclusive OR operation with the conversion information is performed, the command is correctly restored when the lower 2 bits of the conversion initial information is “00”, but the lower 2 bits of the conversion initial information is other than “00”. In case the command is not restored correctly. Note that a case where the command is not correctly restored is added as compared with the case of the first embodiment.

  In the configuration of the fourth embodiment, even if correct first conversion information and correct second conversion information are used, a command cannot always be uniquely and correctly restored from the conversion upper word and conversion lower word. It becomes more difficult to identify various commands from the communication information transmitted from the main control board 301 to the sub control board 302 than in the case of the first embodiment. As a result, various commands can be transmitted more safely than in the first embodiment. In addition, since whether or not to replace the bit arrangement of the upper word and lower word of the command is individually selected according to the bit information with different conversion initial information, whether or not the replacement is appropriate depends on the same bit information of the conversion initial information. The correct first conversion information and the correct second conversion information are used compared to the case of selecting all at once and selecting whether or not to replace the bit arrangement for only one of the upper word and the lower word. However, the number of commands that are not correctly restored from the converted upper word and the converted lower word increases, and it becomes more difficult to identify various commands from the communication information.

  Note that in the command, the upper half bit information (corresponding to the above upper word) is information for identifying the general command type (for example, information for identifying the command type as shown in FIG. 25). ) And information for subdividing and identifying the lower half bit information (corresponding to the lower word above) within the type (for example, if it is an internal information command, information specifying the game state of the transfer destination) Or the information indicating the number of continuations of the game state of the transfer destination), the upper half of the bit information and the lower half of the bit information are hierarchically grouped in meaning. 4, if such a command is adopted, it is possible to ensure the easy identification of the command in the sub-control board 302 and change each bit by changing the bit arrangement in each layer. Change position to bit sequences, for example, than the case of changes that replace the upper word and lower word can be difficult to identify the various commands from the communication information.

  In the above embodiment 4, the case where the upper byte and lower byte of specific information (information after exclusive logical operation of the upper word and lower word of the command) are replaced has been described. A configuration in which the bit arrangement of information is changed, for example, a configuration in which even-numbered bits and odd-numbered bits of specific information are replaced can be adopted. In the fourth embodiment, the bit arrangement is changed for all bits constituting specific information. However, the bit arrangement may be changed for some bits of the specific information.

  In the fourth embodiment, the configuration for selecting whether or not to change the bit arrangement of specific information based on a part of information (0th bit and 1st bit) of the conversion initial information has been described. A configuration in which specific information is always changed in a different manner based on a part of the initial information, for example, when the 0th bit of the converted initial information is “0”, the even-numbered bit and the odd-numbered bit of the specific information When the 0th bit is “1” and the upper byte and the lower byte of the specific information are replaced, it can be configured.

  In the above-described embodiment 4, two pieces of specific information (information after exclusive logical operation on the upper byte and lower byte of the command) are individually obtained based on individual information and part of the initial conversion information. The case of changing has been described, but a configuration in which two specific information is changed in a batch based on common information in the conversion initial information, for example, the bit arrangement is changed based on only one bit information in the conversion initial information If the information is “1” by selecting whether or not to perform, the bit arrangement of both of the two specific information can be changed.

  In the fourth embodiment, the case where the bit arrangement is changed after the conversion of the upper byte and the lower byte of the command based on the first conversion information and the second conversion information has been described. However, the bit arrangement of the upper byte and the lower byte of the command is changed. It can be set as the structure which performs the conversion by 1st conversion information or 2nd conversion information after changing.

  In the fourth embodiment, the case of applying to the configuration of the first embodiment has been described. However, the fourth embodiment can be applied to the second embodiment. However, when applied to the second embodiment, for the two-word command communication other than the first time, the “conversion initial information” and the identification character “i” are “second conversion information in the previous two-word command communication”, respectively. And the identification character “j”. In the configuration of the second embodiment, information related to bit array replacement is not sent to the sub-control board 302 for each communication. Therefore, it is particularly preferable to apply to the second embodiment. .

  Further, the configuration described in the third embodiment can be combined with the fourth embodiment.

[Embodiment 5]
The slot machine of the fifth embodiment converts the bit arrangement within the range of information converted by the first conversion information or the information converted by the second conversion information by the slot machine of the fourth embodiment, and a part of the initial information However, the bit information is rearranged between the information converted by the first conversion information and the information converted by the second conversion information.

  In the following, components that are substantially the same as those of the slot machine according to the fourth embodiment will be denoted by the same reference numerals, and redundant description will be omitted. Differences will be described in detail with reference to FIGS. 43 to 45. . 43 and 44 are explanatory diagrams showing command conversion modes, and FIG. 45 shows the correlation between the conversion initial information and the upper byte and lower byte of the conversion upper word and the upper byte and lower byte of the conversion lower word. It is typical explanatory drawing.

  In the slot machine according to the fifth embodiment, the converted upper word and the converted lower word, which are sequentially transmitted from the main control board 301 to the sub control board 302, are converted by the first conversion information in the command and the second conversion information. In other words, the composite mode is dynamically changed according to at least part of the conversion initial information. Specifically, when the first bit of the conversion initial information is “0”, the value of the lower byte of the information after the exclusive OR operation between the upper word of the command and the first conversion information, and the command The value of the upper byte of the information after the exclusive OR operation of the lower word and the second conversion information is replaced. On the other hand, when the first bit of the conversion initial information is “1”, the value of the lower byte of the information after the exclusive OR operation of the upper word of the command and the first conversion information, the lower word of the command, Replace the value of the lower byte of the information after the exclusive OR operation with the second conversion information.

  More specifically, when the first bit of the conversion initial information is “0”, as shown in FIG. 43, in the main control board 301, the upper word of the command and the first conversion information R (i + 1) The value CHU′−1 generated from the value CHU ′ of the upper byte of the upper word of the command by the exclusive OR operation with the above) is set as the value of the upper byte of the converted upper word, and the lower word of the command and the second conversion The value CLU′−2 generated from the value CLU ′ of the upper byte of the lower word of the command by the exclusive OR operation with the information R (i + 2) is set as the value of the lower byte of the converted upper word, and the upper word of the command And the value CHD′−1 generated from the value CHD ′ of the lower byte of the upper word of the command by the exclusive OR operation of the first conversion information R (i + 1) and the first conversion information R (i + 1). The value CLD′-2 generated from the value CLD ′ of the lower byte of the lower word of the command is converted by the exclusive OR operation of the lower word of the command and the second conversion information R (i + 2). Set as the value of the lower byte of the lower word. On the other hand, in the sub-control board 302, since the first bit of the conversion initial information included in the communication information from the main control board 301 is “0”, the lower byte of the conversion upper word and the conversion lower word included in the communication information Are rearranged, an exclusive OR operation with the first conversion information R (i + 1) and the second conversion information R (i + 2) is executed to restore the command.

  When the first bit of the conversion initial information is “1”, as shown in FIG. 44, in the main control board 301, the exclusive logic of the upper word of the command and the first conversion information R (i + 1) The value CHU′−1 generated from the upper byte value CHU ′ of the upper word of the command by the sum operation is set as the upper byte value of the converted upper word, and is generated from the lower byte value CHD ′ of the upper word of the command. Value CHD′−1 is set as the value of the lower byte of the converted lower word, and the value CLU of the upper byte of the lower word of the command is obtained by exclusive OR operation of the lower word of the command and the second conversion information R (i + 2). The value CLU'-2 generated from 'is set as the value of the upper byte of the converted lower word, and the value CL generated from the value CLD' of the lower byte of the lower word of the command '-2 are set as the value of the lower byte of the transformation upper word. On the other hand, in the sub control board 302, since the first bit of the conversion initial information included in the communication information from the main control board 301 is “1”, the lower byte of the conversion upper word and the conversion lower word included in the communication information After the lower byte is rearranged, an exclusive OR operation with the first conversion information R (i + 1) and the second conversion information R (i + 2) is executed to restore the command.

  As shown in FIG. 45, when the first bit of the conversion initial information is “0”, the values of the upper byte and lower byte of the conversion upper word and the upper byte and lower byte of the conversion lower word are , "CHU'-1" and "CLU'-2" and "CHD'-1" and "CLD'-2", respectively. When the first bit of the conversion initial information is “1”, the upper byte and lower byte of the conversion upper word and the values of the upper byte and lower byte of the conversion lower word are “CHU′−1”, respectively. And "CLD'-2" and "CLU'-2" and "CHD'-1".

  In the configuration of the fifth embodiment, the conversion upper word includes a portion converted by the first conversion information and a portion converted by the second conversion information in the command, and the conversion lower word is the first of the commands. A portion converted by the first conversion information and a portion converted by the second conversion information, and a combination of one of the first conversion information and the second conversion information and the conversion upper word, the first conversion information, Since the command cannot be correctly restored depending on the combination of either one of the second conversion information and the conversion lower word, various commands are identified from the communication information transmitted from the main control board 301 to the sub control board 302. It becomes more difficult than the first embodiment. As a result, various commands can be transmitted more safely than in the first embodiment.

  In the configuration of the fifth embodiment, if a command having hierarchical meaning is used as described in connection with the fourth embodiment, it is possible to ensure easy identification of commands on the sub-control board 302. By distinguishing bit information between layers and disassembling the meaning of each layer, various commands can be identified from communication information rather than changing the bit arrangement in each layer as in the fourth embodiment. Can be difficult to do.

  In the fifth embodiment, the case has been described where the upper byte and the lower byte of two specific information (information after exclusive logical operation on the upper word and lower word of the command) are appropriately recombined. For example, a configuration in which the even-numbered bit of one specific information and the even-numbered bit of the other are rearranged, or an even-numbered bit of one specific information and the odd-numbered bit of the other It can be configured. Further, in the fifth embodiment, recombination is executed for a part of bits constituting specific information. However, the recombination may be executed for all bits of specific information.

  In the fifth embodiment, the configuration in which part of two pieces of specific information is always changed in a different manner based on part of information (first bit) of the conversion initial information has been described. It can be set as the structure which selects whether two specific information is changed based on the information of a part.

  In Embodiment 5 described above, a configuration has been described in which recombination is performed on information after an exclusive logical operation on an upper word and a lower word of a command. However, rearrangement is performed on an upper word and a lower word of a command. A configuration in which conversion using the first conversion information or the second conversion information is executed later may be used.

  In the fifth embodiment, the case of applying to the configuration of the first embodiment has been described. However, the fifth embodiment can also be applied to the second embodiment. However, when applied to the second embodiment, for the two-word command communication other than the first time, the “conversion initial information” and the identification character “i” are “second conversion information in the previous two-word command communication”, respectively. And the identification character “j”. In the configuration of the second embodiment, information related to the rearrangement of the bit arrangement is not sent to the sub-control board 302 for each communication, so that it is particularly preferable to apply to the second embodiment. .

  Moreover, it can be set as the structure which combines the structure as described in said Embodiment 3 and said Embodiment 4 with respect to this Embodiment 5. FIG.

[Embodiment 6]
The slot machine of the sixth embodiment does not have various configurations for handling the actual game media like the game machines of the first to fifth embodiments, and lends, pays out, bets and pays out the game media by a credit function. It is the structure which can perform virtually. In the following description, components that are substantially the same as those of the slot machine of the first embodiment are denoted by the same reference numerals, and redundant description is omitted. Differences will be described in detail with reference to FIGS. 46 to 49. . 46 is a block diagram illustrating an example of an electrical configuration, FIG. 47 is an explanatory diagram illustrating a cooperative relationship in command communication between the main control board 301 and the settlement control board 303, and FIGS. It is explanatory drawing showing the operation | movement in the main control board 301 and the adjustment control board 303 relevant to command communication, respectively.

  As shown in FIG. 46, the slot machine of the sixth embodiment does not include the selector 190, the inserted medal detection device 203, the hopper device 109, and the discharge medal detection device 247 as shown in FIG. Further, a settlement control board 303 is provided, and the number of credits is managed by the settlement control board 303 instead of the main control board 301. Further, the credit amount display device 105, the bet operation device 106 and the settlement operation device 108 are electrically connected to the settlement control board 303. Further, the settlement control board 303 is electrically connected to a recording medium RW device 290 that reads information from a recording medium (not shown) and writes information to the recording medium.

  In the slot machine of the sixth embodiment, when a game is started, when a recording medium is mounted on the recording medium RW device 290, the number of medals corresponding to the amount recorded on the recording medium and the number of medals is stored as the number of credits. Are displayed on the credit number display device 105. The subsequent operation accompanying the progress of the game is substantially the same as the operation in the credit mode. However, when the maximum prescribed number of bets has been completed, information indicating that is transmitted from the settlement control board 303 to the main control board 301, and when winning a predetermined combination, the number of payouts corresponding to that combination is displayed. Information to be transmitted is transmitted from the main control board 301 to the settlement control board 303. In addition, there is substantially no upper limit (50 cards) in the number of credits as in the first embodiment, and all medals obtained as the game progresses are counted as credits. Further, when the settlement operating device 108 is operated, the number of credits is written on the recording medium as the number of stored medals.

  Here, a mode of command communication from the main control board 301 to the settlement control board 303 will be described. In the slot machine of the sixth embodiment, command conversion from the main control board 301 to the sub control board 302 is not performed as in the case of the first embodiment.

  As shown in FIG. 47, prior to the first command communication, the following initial communication is performed between the main control board 301 and the payment control board 303 when the slot machine is started up.

  In the initial communication, first, in the main control board 301, the unique ID of the CPU 311 (“initial information” in the figure: one word information) is acquired (initial information acquisition process SA01) as in the first embodiment, and the unique ID is obtained. Are set in the first sub conversion information (1 word information) and the second sub conversion information (1 word information). Further, the second sub conversion information (unique ID) is transmitted as initial information to the settlement control board 303 (initial information transmission processing SA02). The first sub conversion information and the second sub conversion information are used to generate the first conversion information and the second conversion information in the first command communication.

  Next, when the payment control board 303 receives the second sub conversion information (unique ID) from the main control board 301, the second sub conversion information (unique ID) becomes the first sub conversion information (1 word information). And the second sub-conversion information (1-word information) (initial information reception process SB01). Further, the first main conversion information is generated by one linear feedback shift operation (see FIGS. 29 and 30) for the second sub-conversion information, and one linear feedback shift is performed for the first main conversion information. The second main conversion information is generated by the calculation (conversion information generation processing SB02). The generated first main conversion information and second main conversion information are transmitted to the main control board 301 (conversion information transmission processing SB03). The first main conversion information and the second main conversion information are used to generate the first conversion information and the second conversion information in the first command communication.

  Finally, in the main control board 301, the first main conversion information and the second main conversion information transmitted from the settlement control board 303 are stored (conversion information receiving process SA03). As a result, the initial communication is completed, and the occurrence of a situation in which a command should be transmitted to the checkout control board 303 (start of the first command communication) is awaited.

  When a situation in which a command is to be transmitted to the settlement control board 303 occurs in the main control board 301, processing relating to the first command communication is started. In this command communication, first, a command is generated (command generation processing SA11), first conversion information is generated from the first sub conversion information and the first main conversion information, and the second sub conversion information Second conversion information is generated from the second main conversion information (conversion information generation processing SA12). Further, the upper word of the generated command is converted by the first conversion information to generate a conversion upper word (the upper word of the conversion command), and the lower word of the generated command is converted by the second conversion information. Thus, a conversion lower word (lower word of the conversion command) is generated (communication information generation processing SA13). The generated conversion upper word and conversion lower word are transmitted to the settlement control board 303 (communication information transmission processing SA14).

  Next, in the settlement control board 303, when the conversion upper word and the conversion lower word are received from the main control board 301 (communication information reception process SB11), the first sub conversion information and the first main conversion information are used as the first. The conversion information is generated, and the second conversion information is generated from the second sub conversion information and the second main conversion information (conversion information generation process SB12). Further, the conversion upper word is converted by the first conversion information to extract the upper word of the command, and the conversion lower word is converted by the second conversion information to extract the lower word of the command (command extraction processing) SB13). By this extraction, the command generated by the main control board 301 is restored, and the transmission of the command to the settlement control board 303 is completed.

  Next, in the payment control board 303, in preparation for the next command communication ("second command communication" in the figure), the first main conversion information is used as the first sub conversion information and the second main conversion information. The information is set as the second sub conversion information, and first main conversion information and second main conversion information are newly generated from the newly set second sub conversion information (conversion information). Generation process SB14). The newly generated first main conversion information and second main conversion information are transmitted to the main control board 301 for the next command communication.

  Next, when the main control board 301 receives the first main conversion information and the second main conversion information from the settlement control board 303, the first main conversion information and the second main conversion held before the reception. Information is newly set as the first sub-conversion information and the second sub-conversion information, respectively, and the received new first main conversion information and second main conversion information are the first sub-conversion information and the first sub-conversion information, respectively. It is newly set as main conversion information and second main conversion information (conversion information reception processing SA15). When this setting is completed, the first command communication is completed, and the next command communication is started.

  In the second and subsequent command communications, processing related to each command communication is repeated in the same manner as the first command communication.

  Here, the mode of command conversion will be specifically described. In the main control board 301, as shown in FIG. 48, the first conversion information for converting the upper word CH ″ of the command is the value R (k−2) of the first sub conversion information and the first main information. It is generated by exclusive OR operation with the value R (k) of the conversion information. And, the upper word CH ″ of the command is converted upper word CH by the exclusive OR operation of itself and the first conversion information. "-1". Note that the first sub-conversion information in the main control board 301 is the unique ID of the CPU 311 acquired in the main control board 301 in the first command communication. In the round command communication, it is the first main conversion information received from the settlement control board 303 in the initial communication, and in the subsequent command communications, from the settlement control board 303 accompanying the previous command communication. Receiving The first main conversion information in the main control board 301 is the first main conversion information received from the settlement control board 303 in the initial communication in the first command communication. In the subsequent command communication, the information is the first main conversion information received from the settlement control board 303 in association with the previous command communication.

  Similarly, the second conversion information for converting the lower word CL ″ of the command includes the value R (k−1) of the second sub conversion information and the second main conversion information as shown in FIG. The lower word CL ″ of the command is generated by the exclusive OR operation with the value R (k + 1) of the converted value and the converted lower word CL ″ −2 by the exclusive OR operation of the self and the second conversion information. Note that the value R (k + 1) is subjected to a linear feedback shift operation (see FIG. 29B) twice for the value R (k−1), as shown in FIG. Note that the second sub-conversion information in the main control board 301 is the unique ID of the CPU 311 acquired in the main control board 301 in the first command communication. In the case of twice command communication, the initial communication It is the second main conversion information received from the control board 303, and in the subsequent command communication, it is the second main conversion information received from the settlement control board 303 accompanying the previous command communication. In the first command communication, the second main conversion information in the main control board 301 is the second main conversion information received from the settlement control board 303 in the initial communication. The second main conversion information received from the settlement control board 303 accompanying the previous command communication.

  On the other hand, in the settlement control board 303, as shown in FIG. 49, the first conversion information for converting the conversion upper word CH ″ −1 is the value R (k−2) of the first sub conversion information. It is generated by an exclusive OR operation with the value R (k) of the first main conversion information, and the conversion high-order word CH ″ −1 received from the main control board 301 is the self and the first conversion information. The command is converted into the upper word CH ″ of the command by the exclusive OR operation. Note that the first sub-conversion information in the settlement control board 303 is obtained from the main control board 301 in the initial communication in the first command communication. The received initial information (unique ID of the CPU 311), in the second command communication, the first main conversion information generated in the initial communication, and in the subsequent command communication, Command through In addition, the first main conversion information in the checkout control board 303 is the first main conversion information generated in the initial communication in the first command communication. It is information for conversion, and in the subsequent command communication, it is the first main conversion information generated accompanying the previous command communication.

  Similarly, the second conversion information for converting the conversion lower word CL ″ −2 is the value R (k−1) of the second sub conversion information and the value R (k + 1) of the second main conversion information. The conversion lower word CL ″ −2 received from the main control board 301 is converted into the lower word CL ″ of the command by the exclusive OR operation between itself and the second conversion information. Note that the second sub-conversion information in the settlement control board 303 is the initial information (unique ID of the CPU 311) received from the main control board 301 in the initial communication in the first command communication. In the second command communication, it is the second main conversion information generated in the initial communication. In the subsequent command communication, the second main conversion information generated in association with the previous command communication. Information. Further, the second main conversion information in the settlement control board 303 is the second main conversion information generated in the initial communication in the first command communication, and in the subsequent command communication, This is the second main conversion information generated accompanying the previous command communication.

  In the configuration of the sixth embodiment, when a command transmitted from the main control board 301 to the checkout control board 303 is to be identified, information transmitted from the main control board 301 to the checkout control board 303 (conversion upper word and conversion) Both the low-order word) and information transmitted from the settlement control board 303 to the main control board 301 (information indicating various conversions and information indicating that the maximum prescribed number of bets have been completed) must be monitored. Compared to the case where only information transmitted from the control board 301 needs to be monitored, it is possible to make it difficult to analyze an unauthorized command. As a result, various commands can be transmitted safely. Further, by illegally transmitting an unauthorized command to the settlement control board 303, it is possible to suppress an illegal act that increases the number of credits illegally. Hereinafter, this effect is referred to as “effect A”.

  When the wiring group that transmits information in one direction from the main control board 301 to the settlement control board 303 is different from the wiring group that transmits information in the opposite direction, transmission control and reception control in each board. Can be realized with simple element configuration and processing configuration, and it is necessary to simultaneously monitor the wiring group with different physical routing, that is, the wiring group to which the conversion command is transmitted and the wiring group to which various conversion information is transmitted. Therefore, it is possible to make it difficult to analyze illegal commands. On the other hand, when transmitting the information from the main control board 301 to the payment control board 303 and the information in the opposite direction through the same wiring group, the element configuration and processing configuration related to transmission control and reception control in each board are as follows: Although it is more complicated than the case of transmitting with different wiring groups as described above, it is difficult to specify which direction the information is transmitted, making it difficult to analyze illegal commands. can do.

  Further, in the configuration of the sixth embodiment, since the linear feedback shift calculation for generating various types of conversion information used for converting the command is executed by the settlement control board 303, the calculation is mainly performed. Compared to the case where the control board 301 executes, the processing load on the main control board 301 that manages the game progress in an integrated manner can be reduced. Thereby, game progress can be performed smoothly. In the following, this effect is referred to as “action effect B”.

  In the configuration of the sixth embodiment, since various main conversion information used for generating the conversion command is transmitted and received in communication before the conversion command is generated, the various main conversion information is converted into the conversion command. Is transmitted at a time interval. For this reason, as compared with the case where the main conversion information is transmitted close in time at the timing of transmitting the conversion command, it becomes difficult to associate the conversion command with various main conversion information, and the unauthorized command Can be made more difficult. Hereinafter, this effect is referred to as “effect C”. The same applies to the association between the conversion command and various sub-conversion information.

  In the configuration of the sixth embodiment, the information transmitted from the settlement control board 303 is synchronized with the transmission of the conversion command separately from the various main conversion information transmitted in synchronization with the transmission of the conversion command. Information (information indicating that the maximum specified number of bets has been completed) is included without being sent. For this reason, while the main conversion information is transmitted a plurality of times, the number of times other information is transmitted from the settlement control board 303 varies, making it difficult to associate the conversion command with the main conversion information. Therefore, the information transmitted from the settlement control board 303 includes only other information transmitted in synchronization with the conversion command in addition to the main conversion information, or the settlement control board 303 other than the main conversion information. Compared to the case where no information is transmitted from the server, it is possible to make it more difficult to analyze an illegal command. Information indicating that the maximum specified number of bets has been completed is transmitted for each unit game, but various main conversion information is transmitted only in a part of the unit games with a predetermined winning combination. The transmission of these information is not synchronized. Hereinafter, this effect is referred to as “effect D”. The same applies to the association between the conversion command and various sub-conversion information.

  In the configuration of the sixth embodiment, various commands transmitted from the main control board 301 to the settlement control board 303 are divided based on two pieces of conversion information (first conversion information and second conversion information). As a result of the conversion, it is possible to make it more difficult to analyze illegal commands as compared to the case where various commands are converted all at once based on one conversion information. In the following, this effect is referred to as “effect E”.

  Further, with the configuration of the sixth embodiment, various conversion information itself for generating a conversion command or extracting a command is not transmitted between the main control board 301 and the settlement control board 303, Instead of transmitting various conversion information, conversion information (various main conversion information and various sub-conversion information) for generating various conversion information separately in the main control board 301 and the settlement control board 303 is provided. Sent. For this reason, it is difficult to recognize the conversion information for illegally analyzing the command as compared to the case where various types of conversion information itself is transmitted between the main control board 301 and the settlement control board 303. Analysis of illegal commands can be made more difficult. Hereinafter, this effect is referred to as “effect F”.

  In the configuration of the sixth embodiment, in the current command communication, various main conversion information (current sub conversion information) generated accompanying the previous command communication and the previous command Since various types of conversion information are generated based on various types of main conversion information (current main conversion information) generated in association with communication, the payment control board 303 is transferred from other than the main control board 301. Even if a correct conversion command is transmitted in an unauthorized manner, various main conversion information and sub-conversion information managed by the main control board 301 and the settlement control board 303 are shifted. As a result, when a regular conversion command is transmitted from the main control board 301 after the unauthorized transmission, the payment control board 303 cannot correctly extract the command from the conversion command, and the payment control board 303 illegally transmits the command. It is possible to detect that a command has been sent. Hereinafter, this effect is referred to as “effect G”.

  Further, with the configuration of the sixth embodiment, initial information for generating various types of conversion information is acquired by the main control board 301 and is adjusted based on the initial information transmitted from the main control board 301. Since 303 generates the main conversion information, the main conversion information generated by the adjustment control board 303 is different for each slot machine even if the control contents of the adjustment control board 303 are common to a plurality of slot machines. It can be. For this reason, it is possible to make the analysis of the conversion information transmitted from the payment control board 303 to the main control board 301 difficult while simplifying the manufacture of the payment control board 303.

  In the above-described sixth embodiment, the configuration in which the main control board 301 receives various types of conversion information used for conversion of the command before generating the command has been described. However, various types of information used for conversion of the command after generation of the command are described. It may be configured to request the settlement control board 303 to transmit the conversion information and receive the information from the settlement control board 303. Even if it is this structure, there will exist effects other than the effect C of said effect A-G. Even when the conversion information used for generating the conversion command is transmitted after the command is generated, it is preferable that a part of the conversion information is transmitted before the command is generated. Since some of the conversion information is transmitted at a time interval from the transmission of the conversion command, it is possible to maintain difficulty in associating the conversion command with various sub-conversion information.

  In the sixth embodiment described above, the configuration has been described in which a 2-word command is dividedly converted for each word. However, a 2-word command can be collectively converted by 2-word conversion information. . In this case, only one type of conversion information or conversion information may be used, and a 32-bit (2 words) linear feedback shift operation may be used in generating the conversion information. Even in this configuration, the effects other than the effects E of the above effects A to G are exhibited. Further, a command different from two words such as one word or three words can be dividedly or collectively converted. Note that the bit length of the command and the bit length of the unit for converting the command are preferably unit operation control bits (generally 8 bits or 16 bits) of various control boards or multiples thereof.

  In the above-described sixth embodiment, the case where various types of conversion information are sequentially generated by the linear feedback shift operation for the unique ID of the CPU 311 has been described. However, the various types of conversion information are other internal information that differs for each slot machine. Can be sequentially generated by a linear feedback shift operation on. The initial information for generating various types of conversion information is preferably configured to use different values for each individual slot machine, but may be configured to use values that do not differ for each individual slot machine. Good. For example, there is a configuration in which the value of a counter used so that the value changes substantially continuously is obtained, and various pieces of conversion information are sequentially generated by linear feedback shift operation on the value.

  In the sixth embodiment, the upper word of the command is converted by the first conversion information generated from the first main conversion information and the first sub conversion information, and the second main conversion information and the second sub conversion information are converted. The configuration for converting the lower word of the command by the second conversion information generated from the information has been described. However, in the conversion of either the upper word or the lower word of the command, the main conversion information itself is used as the conversion information. Can do. Even with this configuration, the operational effects A to G described above are exhibited. In addition, in the conversion of both the upper word and the lower word of the command, the main conversion information itself may be used as the conversion information. In this case, it is not necessary to store the main conversion information and the sub conversion information separately, and the calculation for generating the conversion information is not necessary. Even with this configuration, the operational effects other than the operational effect G out of the operational effects A to G described above are exhibited.

  In the sixth embodiment described above, the configuration in which the initial information for generating various types of conversion information is acquired in the main control board 301 has been described. In this case, it is not necessary to transmit information from the main control board 301 to the settlement control board 303 in the initial communication, and the information acquired in the settlement control board 303 is used as the first sub conversion information and the second sub conversion information. To the main control board 301. With this configuration, since no information (initial information) related to various types of conversion information is transmitted from the main control board 301 to the settlement control board 303, only based on information transmitted from the main control board 301. The command cannot be parsed. In addition, in the case of the first embodiment described above, various types of conversion information are not sequentially generated based on predetermined initial information (unique ID of the CPU 311), but in the generation of conversion information accompanying each command communication. Similarly to the above, it is also possible to adopt a configuration in which the value of a counter (random number counter that determines a winning combination) used so that the value changes substantially continuously is acquired for each command communication.

  In the sixth embodiment, the configuration in which various types of conversion information are generated by the linear feedback shift calculation in the settlement control board 303 has been described. However, as in the second embodiment, the settlement control is individually performed in the main control board 301 as well. A configuration for generating various types of conversion information by the same linear feedback shift calculation as that of the board 303, and confirming a match between the conversion information generated by the main control board 301 and the conversion information received from the settlement control board 303; You can also If it is this structure, although said effect B will reduce, the effect G will improve. This is because when a conversion command is illegally transmitted from other than the main control board 301 to the settlement control board 303, the unauthorized transmission can be detected immediately after that (without waiting for the next command communication).

  In the sixth embodiment, the first main conversion information is generated by one linear feedback shift operation on the second sub conversion information (second main conversion information in the previous command communication), and the second main conversion is performed. In the above description, the information is generated by one linear feedback shift calculation for the first main conversion information. However, the information may be generated by a plurality of linear feedback shift calculations. The number of linear feedback shift operations for generating such information may be different. The first main conversion information and the second main conversion information are not limited to be generated by a fixed number of linear feedback shift operations, and the number of linear feedback shift operations for generating such information may be determined as described above. The configuration can be dynamically changed by the same method as the generation of various types of conversion information in the configuration described in the third mode and the accompanying configuration. For example, the number of operations for generating the first main conversion information is determined based on the bit information constituting the second sub conversion information, and the second main conversion information is generated based on the other bit information. The structure which determines the frequency | count of calculation for this is mentioned.

  In the sixth embodiment, the configuration has been described in which the command itself is converted by the conversion information based on various types of conversion information, and the conversion command itself is transmitted. However, the fourth embodiment, the fifth embodiment, and the accompanying description are given. The bit arrangement of at least one of the information generated in the process of converting the command, the conversion command, and the command into the conversion command can be dynamically changed by the same method as the generation of the conversion command in the above configuration. For example, a configuration for determining whether to change the bit arrangement of the command based on the bit information constituting the second sub-conversion information and for determining a change pattern of the bit arrangement of the conversion command based on the other bit information Is mentioned.

  In the sixth embodiment, the command communication between the main control board 301 and the settlement control board 303 has been described. However, the command communication between the main control board 301 and another control board such as the sub control board 302 is performed. The same command communication can be applied to this. In order to realize the effect G in these command communications, the main control board 301 may store various types of conversion information individually for each control board.

  In the sixth embodiment, the configuration in which command communication is performed between the main control board 301 and the payment control board 303 has been described. However, in command communication between the main control board 301 and other control boards, For command communication between at least one control board and the main control board 301, the command communication according to the method of the sixth embodiment and for command communication between at least one other control board and the main control board 301, the first embodiment or The command communication according to the method of the second embodiment can be combined.

  In the sixth embodiment, the configuration in which various main conversion information is generated by the control board (settlement control board 303) to which the command is transmitted has been described. However, other control boards (for example, the sub control board 302) are described. Thus, various types of main conversion information can be generated and transmitted to both the main control board 301 and the settlement control board 303. Even if it is this structure, there can exist said effect A-G. In this case, it is only necessary to request generation of various new main conversion information from the main control board 301 or the settlement control board 303 to other control boards for each command communication, for each unit game, or periodically.

  Similar to the generation of various types of conversion information in the sixth embodiment, in the first to fifth embodiments, the first conversion information generated in the previous command communication and the first conversion information generated in the current command communication. New information is generated from the conversion information, and the command and the initial conversion value in the current command communication can be converted using the information. In particular, when this configuration is applied to the command communication of the first embodiment, the same effect as the above-described operational effect G is newly achieved.

  Hereinafter, the characteristics of the invention group extracted from the various forms described above will be described while showing effects and the like as necessary. For easy understanding, the corresponding configurations in the above-described various modes are appropriately indicated by parentheses or the like, but are not limited to the specific configurations indicated by the parentheses or the like. In addition, the meanings and examples of terms described in each feature can be applied as the meanings and examples of terms described in other features described in the same wording.

  In a typical conventional gaming machine, a lottery is performed in response to a winning of a game ball in a start winning device, and a variation display of a pattern is performed on a display screen of a display device. If the result of the lottery is a win, the combination of specific pictures and the like is finally stopped and displayed on the display screen, and a transition is made to a profit gaming state that is advantageous to the player. In this profitable game state, a plurality of types of game modes are set in which the number of continuous rounds in the special game state and whether or not the special game state is accompanied by a specific game state that is more advantageous to the player than the normal game state are set. ing. Although the gaming machines have been diversified in the above gaming machines, there is still room for improvement from the viewpoint of improving the interest of the game.

  In the case of the configuration of the feature A4, since the unique identification number of the central processing unit is used as basic information for the initial communication, the random number counter is not started when the first control device is started up. Even if there is, instruction information can be transmitted reliably. Furthermore, since “0” is not normally set as the unique identification number of the central processing unit, it functions reliably as basic information. In addition, since the basic information can be set to a random value in each communication, it is further difficult to identify various instruction information from the communication information.

Thereby, it is also possible to suppress an illegal act of illegally transmitting instruction information for bringing the player into an advantageous state to the second control device and excessively acquiring medals. In addition, since it is not necessary to transmit the specific information necessary for extracting the instruction information before conversion from the conversion instruction information together with the conversion instruction information in each communication, various instruction information can be transmitted safely. In addition, since specific information for each communication is managed independently between the first control device and the second control device, even if communication information is illegally transmitted from other than the main control board 301, If the communication information is transmitted from the first control device, the instruction information cannot be correctly extracted from the communication information in the sub-control board 302, and it can be detected that the communication information is illegally transmitted to the second control device.

The initial information setting means obtains the unique identification number of the central processing unit as the predetermined initial information in starting up the first control device accompanying the start of power supply.
A configuration is preferred.

  In the case of the configuration of the feature B4, since the unique identification number of the central processing unit is used as basic information for the first communication, the random number counter is not started when the first control device is started up. Even if there is, instruction information can be transmitted reliably. Furthermore, since “0” is not normally set as the unique identification number of the central processing unit, it functions reliably as basic information. In addition, since the basic information can be set to a random value in each communication, it is further difficult to identify various instruction information from the communication information.

Even if there is, instruction information can be transmitted reliably. Furthermore, since “0” is not normally set as the unique identification number of the central processing unit, it functions reliably as basic information. In addition, since the basic information can be set to a random value in each communication, it is further difficult to identify various instruction information from the communication information.

<Feature C1>
A gaming machine according to invention C group is:
A gaming machine including a first control device (for example, a main control board 301) and a second control device (for example, a sub control board 302) capable of communicating with the first control device,
The first control device is generated based on basic information (for example, conversion initial information and second conversion information in the previous two-word command communication) and updated at least every predetermined communication (for example, two-word command communication). Information transmitting means for transmitting communication information including conversion instruction information generated by converting instruction information (for example, a command) accompanying establishment of a predetermined condition based on one type of specific information to the second control device (For example, port output processing S213 ′),

Including information receiving means for extracting information (for example, command reception processing S2104),
In the information transmitting unit and the information receiving unit, the at least one type of specific information is generated by a predetermined calculation (for example, linear feedback shift calculation) on the basic information,
The predetermined number of operations is determined based on at least a part of the basic information (for example, the conversion initial information and the value of the lower 2 bits of the second conversion information in the previous 2-word command communication), Changes due to some information differences,

  Note that “updated for each predetermined communication” means that the update is performed in each communication between the first control device and the second control device, the update is performed in a specific type of communication, It implies the case where it is updated every predetermined number of times.

  With the configuration of the feature C1, since the instruction itself transmitted from the first control device to the second control device is not transmitted / received, it is actually transmitted from the first control device to the second control device. It becomes difficult to identify various instruction information from the communication information to be transmitted, and various instruction information can be transmitted safely. Thereby, it is also possible to suppress an illegal act of illegally transmitting instruction information for bringing the player into an advantageous state to the second control device and excessively acquiring medals. In addition, since it is not necessary to transmit the specific information necessary for extracting the instruction information before conversion from the conversion instruction information together with the conversion instruction information in each communication, various instruction information can be transmitted safely. In addition, since the number of predetermined calculations for the basic information is changed in the generation of specific information used for converting various types of instruction information, the number of calculations in each communication varies. This makes it difficult to estimate the specific information as compared to the case where the specific information is generated by a fixed number of predetermined calculations with respect to the basic information. Therefore, various types of communication information transmitted from the first control device to the second control device are used. It becomes more difficult to identify the commands. In addition, since a part of the basic information is used for determining the number of predetermined calculations in generating the specific information, the specific information can be generated without increasing the amount of information necessary for communication.

  With the configuration of the feature C2, since various instruction information transmitted from the first control device to the second control device is dividedly converted based on a plurality of specific information, various instructions are transmitted from the communication information. It becomes more difficult to identify the information. In addition, since the plural types of specific information necessary for extracting the pre-conversion instruction information from the conversion instruction information is not included in the actually transmitted / received communication information, various specific information is included in the communication information. Various instruction information can be transmitted safely compared to the case where the information is transmitted.

<Feature D1>
The gaming machine according to the invention group D is
A gaming machine comprising a first control device and a second control device (for example, sub-control board 302) capable of communicating with the first control device (for example, main control board 301),
The first control device generates at least one type of specific information (for example, first information) that is generated from basic information (for example, conversion initial information or second conversion information in the previous two-word command communication) and updated for each predetermined communication. Communication information including conversion instruction information generated by converting instruction information (for example, a command) associated with establishment of a predetermined condition based on (one conversion information or second conversion information) is transmitted to the second control device. Including information transmission means to
The second control device receives the communication information from the first control device, and converts the instruction by converting the conversion instruction information included in the communication information based on the at least one type of specific information. Including information receiving means for extracting information;
The information transmission means includes a generation calculation means (for example, an exclusive OR calculation) for performing a predetermined calculation of the instruction information or the information based on the instruction information and the at least one type of specific information, the instruction information or Generation changing means for changing the bit arrangement of information based on the instruction information due to a difference in information corresponding to at least a part of the basic information (for example, conversion initial information R (i) in the main control board 301 in the fourth embodiment) Of the bit arrangement that changes due to the difference between the 0th bit and the first bit, and the rearrangement of the bit arrangement that changes due to the difference of the first bit of the conversion initial information R (i) in the main control board 301 in the fifth embodiment) And generating the conversion instruction information by the generation unit,
The information receiving means is an extraction change that can change the conversion instruction information included in the communication information or a bit arrangement of information based on the conversion instruction information depending on a difference in information corresponding to at least a part of the basic information. Means (for example, rearrangement of the bit arrangement which changes depending on the difference of the 0th bit or the first bit of the conversion initial information R (i) in the sub control board 302 in the fourth embodiment and the conversion in the sub control board 302 in the fifth embodiment Extraction calculation means for performing predetermined calculation of the conversion instruction information or the conversion instruction information and the at least one type of specific information) (rearrangement of bit arrangements changed by the difference of the first bit of the initial information R (i)) (For example, an exclusive OR operation), and the instruction information is extracted by the extraction unit.
It is characterized by that.

  The “information based on instruction information” in the generation calculation unit and the generation change unit means intermediate information generated before conversion from the instruction information to the conversion instruction information. The combination of the calculation target in the generation calculation means and the change target in the generation change means is, for example, a combination of “instruction information” and “information generated by the generation calculation means” or “generation change A combination of “information generated by the means” and “instruction information” can be mentioned. Similarly, “information based on conversion instruction information” in the extraction change means and the extraction calculation means means intermediate information generated before conversion from conversion instruction information to instruction information. The combination of the change target in the extraction change means and the calculation target in the extraction calculation means is, for example, a combination of “conversion instruction information” and “information generated by the extraction change means” or “extraction A combination of “information generated by the calculation means” and “conversion instruction information” can be mentioned.

  With the configuration of the feature D1, since the instruction itself transmitted from the first control device to the second control device is not transmitted / received, it is actually transmitted from the first control device to the second control device. It becomes difficult to identify various instruction information from the communication information to be transmitted, and various instruction information can be transmitted safely. Thereby, it is also possible to suppress an illegal act of illegally transmitting instruction information for bringing the player into an advantageous state to the second control device and excessively acquiring medals. In addition, since the generation change means changes the bit arrangement of the instruction information or the information based on the instruction information due to a difference in information corresponding to at least a part of the basic information, the first control apparatus temporarily changes to the second control apparatus. Even when correct predetermined calculation is performed in the extraction calculation means using the transmitted conversion instruction information and correct specific information, the case where correct instruction information cannot be extracted from the conversion instruction information is included. It becomes more difficult to identify the instruction information based on communication information between the control device and the second control device. Further, in order to make the bit information of the instruction information or the information based on the instruction information different by using a part of the basic information, the extraction of the instruction information from the conversion instruction information in the second control device is performed in the first control. This can be realized without increasing the amount of information necessary for communication between the device and the second control device.

<Feature D2>
In the gaming machine described in the feature D1,
A bit length shorter than the bit length of the instruction information (for example, 32 bits: 2 words) is set as a reference bit length (for example, 16 bits: 1 word),
The predetermined calculation in the generation calculation unit and the extraction calculation unit is performed in units of the reference bit length,
Each of the generation change means and the extraction change means can change at least part of the bit information in the unit information with the reference bit length as a unit (for example, Embodiment 4). Including the rearrangement of the bit arrangement that changes depending on the difference between the 0th bit and the 1st bit of the conversion initial information R (i) on the main control board 301 in FIG.
A configuration is preferred.

  Examples of the “reference bit length” include the bit length of the arithmetic processing unit in the first control device and the second control device, and the bit length of the partial information corresponding to each layer in the instruction information hierarchically grouped in meaning. It is done. Note that the communication unit of information communicated between the control devices (the bit length transmitted and received in one communication) may be the same as the reference bit length or different from the reference bit length.

  With the configuration of the feature D2, the generation of conversion instruction information from the instruction information and the instruction from the conversion instruction information are possible because bit information can be replaced by bit operations executed at high speed in various control devices or simple combinations thereof. Control processing related to information extraction can be speeded up and simplified. Note that the identification information for each layer can be lowered by replacing the bit arrangement within each layer in the instruction information that is hierarchically grouped in meaning. Further, with the configuration of the feature D2, in the generation of the conversion instruction information from the instruction information and the extraction of the instruction information from the conversion instruction information, it is possible to complete a predetermined calculation and a change in bit arrangement for each unit information. Control processing related to the generation and extraction can be simplified.

<Feature D3>
In the gaming machine described in the feature D1 or D2,
Each of the generating changing means and the extracting changing means can change unit information between unit information (for example, the sub information in the fifth embodiment) that can rearrange a part of bit information between unit information in units of the reference bit length. Including recombination of the bit arrangement that changes due to the difference in the first bit of the conversion initial information R (i) on the control board 302),
A configuration is preferred.

  With the configuration of the feature D3, since the bit information can be rearranged by a simple combination of bit operations executed at high speed in various control devices, the generation of the conversion instruction information from the instruction information and the instruction information from the conversion instruction information The control processing related to the extraction of can be speeded up and simplified. In addition, in the instruction information that is hierarchically grouped in meaning, the identification of the instruction information can be reduced by rearranging the bit information between the hierarchies to eliminate the grouping of the meaning of each hierarchy. In addition, with the configuration of the feature D3, information having meanings cannot be extracted from any unit information after the rearrangement regardless of the conversion, and is configured with such unit information. Since communication by communication information increases, it is more difficult to identify various instruction information from information transmitted from the first control device to the second control device than the configuration of the feature D2. Become.

  With the configuration of the feature E1, when the instruction information transmitted from the first control device to the second control device is to be identified, the information transmitted to the first control device and the first control device are transmitted. Since both pieces of information to be monitored must be monitored, it is possible to make it difficult to analyze an unauthorized command compared to the case where only the information transmitted from the first control device needs to be monitored. Thereby, various instruction information can be safely transmitted.

  In the configuration of the feature E1, the first control device that manages the operation by transmitting the instruction information to the second control device receives at least one type of specific information updated for each predetermined communication.
