Description

The present invention relates to fraud prevention of gaming machines that draw lots of occurrence of a specific gaming state (for example, a big hit state) based on a periodic counter value .

  A gaming machine (for example, a ball game machine) includes a periodic counter that circulates and updates between a lower limit value (minimum value) and an upper limit value (maximum value). It is known that a lottery is performed for occurrence of a specific gaming state (for example, a big hit) based on the value of a periodic counter acquired based on a winning ball or winning ball at the starting port.

  Such a periodic counter is also used, for example, to determine a jackpot random number or a jackpot random number initial value, and the jackpot lottery is determined based on the value indicated by the jackpot random number initial value counter at a predetermined timing. When the big hit random number counter makes one round, the big hit random number initial value counter value is newly acquired, and the big hit random number counter is updated from this value. Then, if the value of the jackpot random number counter at the time when the game ball wins the start opening is a preset jackpot value, the jackpot game is started and an advantageous state is provided to the player.

  Here, in order to prevent illegal gaming, the big hit random number initial value counter changes the update start position of the big hit random number counter every time the big hit random number makes one round (every round), and the value of the big hit random number counter becomes the big hit value Is periodically changed.

  As a result, even if the fraudster determines the update timing of the periodic counter based on, for example, the transmission timing of the control signal from the game control device of the gaming machine to the various controlled devices, the change of the initial value of the lap Unless it is analyzed, it is difficult to calculate the value of the periodic counter, and it is extremely difficult to perform an illegal act that generates a specific gaming state (a jackpot state).

  However, in the above conventional example, the value of the cyclic counter is initialized at the time of starting the game control device or the like, and therefore the jackpot random number counter is updated (incremented) from a predetermined initial value (for example, 0). When the first round is completed, the count start value is first stirred by the value of the random number initial value counter.

  For this reason, as long as it is limited to the first round of the jackpot random number counter immediately after the initialization of the game control device, since the random number stirring by the jackpot random number initial value counter is not performed, the program of the game control device is analyzed, As long as the jackpot value (for example, 7) of this random number counter is captured, the reset is forcibly reset and the winning counter is illegally transmitted by sending a winning detection signal at a timing when the random number counter reaches a predetermined jackpot value. There is a problem that a jackpot game is played.

  Here, in order to forcibly generate the initialization of the game control device, the fraudster intervenes a fraud board that generates a reset signal for the game control device between the power supply board and the game control device. In addition, in order to arbitrarily operate the winning signal of the starting port, an illegal board is also interposed in a circuit related to the switch of the starting port. Due to the recent miniaturization of electronic components, the size of these illegal boards has become very small, and there has been a problem that they cannot be easily found just by looking at the back of the game board.

The present invention has been made in view of the above problems, it shall be the purpose of preventing fraud in the difficult capture of random numbers from the outside.

A counter value agitation unit, and the main process is a loop that is repeatedly executed after execution of the loop pre-process that is set as a prohibition period of the timer interrupt process after the game control is activated. And the detection means is configured to execute the input process in the timer interrupt process and detect occurrence of the predetermined event based on an execution result of a plurality of input processes . 1 counter value agitating means, before SL during the prohibition period to become the loop pretreatment of the timer interrupt processing, set the orbiting initial value of 1 lap of the periodic counter, the initial value Ca The counter is updated in the loop process and the timer interrupt process, respectively .

According to a second aspect of the present invention, there is provided power supply means for supplying power to the gaming machine, reset signal sending means for sending a reset signal to the game control means when the gaming machine is turned on, and monitoring fluctuations in the supplied power supply voltage. And a power failure detection means for transmitting a power failure detection signal upon detecting a decrease in the voltage, wherein the game control means is used as a work area when the game control is executed and backup power is supplied from the power supply means. Backup storage means, a power failure information storage means for storing predetermined power failure information in the backup storage means based on the input of the power failure detection signal from the power failure detection means, and the reset from the reset signal sending means Based on the input of the signal, reset means for resetting the game control, and the game control is reset by the reset means. Based on the fact that the power failure information determination means for determining the power failure information stored in the backup storage means and the power failure information determination means determines that the power failure information is a normal value. A power failure recovery means capable of restoring the game control to a state before power-off based on information stored in the backup storage means; and the power failure information determination means determines that the power failure information is not a normal value. Based on the information, the initialization means for initializing the storage contents of the backup storage means, and the power failure information determination means determine that the power failure information is not stored, and the power is shut off. And a notification control unit that performs control for notifying that the reset is not performed .

A first aspect of the present invention is the periodic counter is updated to circulate, to obtain the value of the periodic counter when a predetermined event of the game, such as winning the game ball is detected, the lottery of JP Teiyugi state However, after the game control is reset, before the execution of the loop pre- processing of the main process, which is a prohibition period of the timer interrupt process in which the input process for detecting a predetermined event is executed , Since the initial value generating means sets a random value generated within the range between the minimum and maximum values of the periodic counter as the initial value of the first round of the counter, the initial value of the cyclic counter after reset is set. It becomes difficult to capture the value from the outside. Even if the fraudster determines the update timing of the periodic counter, the first input process is not executed until the initial rotation value of the first cycle of the periodic counter is set after resetting, Can be prevented.
In addition, when the periodic counter reaches the circulation initial value, an initial value counter value different from that of the initial value generating means is set as a new circulation initial value of the periodic counter. It becomes difficult to capture the value of the automatic counter.

According to the second aspect of the invention, it is informed that the reset is not accompanied by a power shutdown, so that a warning can be issued to a hall employee or the like regardless of the progress of the game .

  When there is a winning game ball at the start port 16, the variable display device 8 sequentially displays the display symbols composed of the numbers and characters described above. When a winning at the start port 16 is made at a predetermined timing (specifically, when the special symbol random number counter value at the time of winning detection is a winning value), it is a big hit state and three display symbols are arranged. Stop in state (big hit symbol). At this time, the large winning opening of the variable winning apparatus 10 opens wide for a predetermined time (for example, 30 seconds), and a large number of game balls can be acquired.

  The winning of the game ball to the start port 16 is detected by the special symbol start sensor 52.

  The normal symbol display unit 7 starts to display a variation of a normal symbol (for example, a symbol consisting of one number) when a winning game ball is awarded to the normal symbol starting gates 27A and 27B. When winning to the normal symbol start gates 27A and 27B is made at a predetermined timing (specifically, when the normal symbol random number counter value at the time of winning detection is a winning value), it becomes a hit state related to the normal symbol, A normal symbol stops at a winning symbol (hit number). At this time, the normal variation winning device 9 provided in front of the starting port 16 opens wide for a predetermined time (for example, 0.5 seconds), and the winning possibility of the game ball to the starting port 16 is increased.

  The passing of the game ball to the normal symbol start gate is detected by the normal symbol start sensors 53A and 53B. The passing timing of the game ball (specifically, the value at the time of passage detection of the normal symbol random number counter provided in the game control device 100) is a predetermined memory in the game control device 100 as the normal symbol winning memory. In the area (ordinary symbol random number storage area), a predetermined number of times (for example, a maximum of four consecutive times) is stored as a limit. The number stored in the normal symbol winning memory is displayed on the normal symbol storage state display 19 composed of four LEDs provided on the left and right of the normal symbol display 7.

It should be noted that, by identifying the reset signal lines in the cable 101 so that the reset signal lines can be easily identified, it is possible to easily find an illegal board.

  FIG. 4 is a block diagram showing the connection of each control device. The game control device (main board) 100, the display control device (display control board) 150, the decoration control device (lamp control board) 200, and the sound control device (voice control board). ) 300, various control devices such as a discharge control device (dispensing control board) 400, a launch control device (launch control board), and the like are provided.

  The game control device 100, the display control device 150, the decoration control device 200, the sound control device 300, and the discharge control device 400 are each configured by a CPU, a RAM, a ROM, and an input / output interface (I / F).

  Detection signals from various detection devices are input to the game control device 100 and input to the CPU via an input / output interface. These various detection devices include general winning opening sensors 51.1 to 51. N, a special symbol start sensor 52 for starting a variable display game by the variable display device 8 by detecting a winning ball at the start port 16, and a normal symbol display for determining the operation of the normal variable winning device 9 by detecting the ball Normal symbol start sensors 53A and 53B for starting the movement of the device 7, a count sensor 54 for detecting a winning in the big winning opening and a big winning opening continuation sensor 55, a metal frame opening sensor for detecting the opening of the glass frame on the front of the game board 56, an overflow sensor 57 for detecting that the game balls discharged by the discharge unit 600 are excessively stored, a half-end ball detection sensor for detecting that supply of the game balls to the discharge unit 600 is insufficient, and the like. It is.

  Based on these detection signals, the CPU of the game control device 100 executes a program (game program) recorded in the ROM, and performs overall control of the game (game control).

  Specifically, the game control device 100 outputs a display control command signal to the display control device 150 by display parallel communication, outputs a decoration control command signal to the decoration control device 200 by lamp parallel communication, and sends it to the sound control device 300. A sound control command signal is output by voice parallel communication, and a prize ball control command signal is output to the discharge control device 400 by prize ball parallel communication to control these subordinate control devices. Note that data from the game control device 100 to each subordinate control device (display control device 150, decoration control device 200, sound control device 300, and discharge control device 400) is communicated in one direction, and the subordinate control device to the game control device 100. No data is sent to the.

  The game control device 100 sends control signals to the big prize opening solenoid 10A and the normal variable prize opening solenoid 9A, and controls the energization of these solenoids, thereby opening and closing the special variable prize winning device 10 and the normal variable prize winning device 9. To control. Further, a control signal is transmitted to the normal symbol display 7 to control this display.

  In addition, the game control device 100 monitors whether or not the prize ball is discharged accurately. Specifically, monitoring and awarding whether or not the number of prize balls commanded to be ejected transmitted as a prize ball control command signal to the ejection control device 400 matches the actual number of ejections counted by the prize ball detection sensors 713A and 713B. Monitors whether or not the prize ball is discharged even though the ball discharge command is not transmitted.

  If an abnormality such as a prize ball being discharged is recognized even though the prize ball discharge command signal has not been transmitted, an abnormality handling process is performed. For example, the abnormality detection signal is output from the frame external information output unit 42A to the management device (hall computer), the decoration control command signal is transmitted to the decoration control device 200, and the first notification lamp (prize ball abnormality notification LED) 31 is transmitted. Flashes to notify the abnormality. Alternatively, the game is forcibly stopped by stopping the game control, stopping the hitting of the hit ball, or the like.

  A CPU (microprocessor) 110 of the game control device 100 includes a ROM that stores a program for performing game control and a RAM 111 for executing the program.

  The RAM 111 is used as a work area when the CPU 110 controls the game. The RAM 111 is supplied with power from a backup power source (not shown) even in the event of a power failure, and necessary data is backed up. The RAM 111 includes a backup area and a control area. The backup area is an area where the data contents are not initialized in principle when returning from a power failure. In addition to the check data, the jackpot random number initial value counter (stirring value generating means), jackpot random number counter (periodic counter), which will be described later, special Symbol random number memory, ordinary symbol random number counter, ordinary symbol random number memory, effect random number counter, etc. are stored in the corresponding storage areas. On the other hand, the control area is an area other than the backup area and stores a timer value and the like.

  The discharge control device 400 receives detection signals from prize ball detection sensors 713A and 713B that detect discharged balls. Specifically, the detection signals of the winning ball detection sensors 713A and 713B that detect the balls discharged from the discharging unit 600 as the winning balls, and the rental ball detection sensor that detects the balls discharged as the rental balls from the discharging unit 600 The detection signals 714A and 714B are input. Then, the discharge control device 400 controls the discharge of the game ball from the discharge unit 600 and the flow path switching in the flow path switching unit based on the prize ball control command signal.

  In addition to the prize ball control command signal from the game control device 100, a ball rental request signal is input from the card unit 2 to the discharge control device 400. The discharge control device 400 controls the discharge unit 600 based on the prize ball control command signal and the ball rental request signal, and uses the detection signals of the discharge sensors (ball rental detection sensors 714A and 714B) as the discharge ball detection means, Releases rental balls.

  The detection signals of the prize ball detection sensors 713A and 713B are also input to the game control device 100 via the relay board.

  During normal operation, the game control device 100 and the discharge control device 400 are called based on clock pulses generated at intervals of a predetermined time (2 milliseconds) (or by providing a wait for a predetermined time (2 milliseconds)). By interruption processing, the outputs of the prize ball detection sensors 713A and 713B are read at predetermined time intervals, and the counter (confirmation counter, storage counter) is subtracted. Further, when a power failure occurs during normal operation of the game control device 100 and the discharge control device 400, a power failure detection process is executed by an NMI interruption based on a power failure detection signal generated by the power failure detection circuit 253.

  The decoration control device 200 is input with a decoration control command signal that is a command signal for turning on (flashing) the lamp from the game control device 100, and drives various lamps to light. Specifically, when the gaming control device 100 detects an abnormality of the gaming machine 1, the abnormality notification lamp (first notification lamp) 31 is turned on. In addition, when a prize ball control command signal is sent from the game control apparatus 100 to the discharge control apparatus 400 and the prize ball discharge starts, the prize ball discharge lamp 32 is turned on. Furthermore, when the gaming machine 1 is in a big hit state, the decoration lamps 45.1 to 45. Turn on (flash) N.

  The power supply apparatus 250 includes a power supply circuit 251, a power failure detection circuit 253, and a backup power supply circuit 256. The power supply circuit 251 is required for the operation of each control device (the game control device 100, the discharge control device 400, etc.) using the 24 volt AC power received by the gaming machine 1 via the external terminal 42A from the island facility of the game store. It is converted into a DC power source of voltage (12V, 18V, etc.) and supplied to each control device 100, 400, etc. The power failure detection circuit 253 monitors fluctuations in the voltage supplied to the gaming machine, and outputs a power failure detection signal when a voltage drop is detected, and causes a power failure to each control circuit (the game control circuit 100 and the discharge control device 400). Execute the process. The backup power supply circuit 256 is constituted by a large-capacity element (secondary battery, super capacitor, etc.) to which 5V output from the power supply circuit 251 is constantly applied, and the power supply to the gaming machine is stopped (during power failure) Thus, even if the output from the power supply circuit disappears, power is supplied to a circuit that needs to operate even in the event of a power failure. For example, power is supplied to a backup memory that needs to retain stored contents even during a power failure.

  5 and 6 are flowcharts showing an example of a main routine executed by the CPU (microprocessor) of the game control device 100. FIG.

  When the reset signal becomes inactive and the CPU 110 starts up, normal interruption is prohibited for initialization processing or power failure recovery processing (S101), and the CPU is initialized (S102). Thereafter, an off signal (a signal corresponding to “0” of the binary signal) is output to all output ports (S103). Since each driver IC of the CPU (microcomputer) 110 is set to OFF (reset) by the reset signal, it is not necessary to output the OFF signal to each port again. However, in step S103, the output port is just in case. An off signal is output.

  Next, it is determined whether or not the power failure flag is normally set (stored) in the RAM 111 (S104). If the power failure flag is normally set, it is determined that the CPU 110 is activated when the power is restored, and step S105 is performed. Then, the power failure recovery process (S105 to S111) is executed.

  On the other hand, if the power failure flag is abnormal (if not normally stored), it is determined that the power supply has been normally turned on or started from reset, and the process proceeds to step S112 to execute initialization processing (S112 to S117). To do.

  The power failure flag is set in an interrupt process (step S155 in FIG. 8) when a power failure occurs, which will be described later. For example, if the power failure occurrence flag is composed of 1-byte data, the value of the area where the power failure flag is set in the RAM 111 (power failure inspection area) is the value at initialization (when the power is turned on (initialized state)). For example, FFh), and when a power failure occurs, a specific value (for example, 55h) is set in this area.

  For this reason, when the value of the power failure inspection area is 55h, the power is turned on after the power is shut off due to the power failure (when the power failure is restored). It can be determined that a normal power-on or a reset has occurred. Although the power outage occurrence flag was once set to 55h, the power cut-off state (power outage state) continued for a long time, and the backup power supply device that backs up the RAM 111 of the gaming CPU 110 exceeded the time that can be backed up. Also when the power failure flag data is other than 55h (when the data is not normally stored), it is determined that the power is normally turned on, and the initialization process (S112 to S117) is executed.

  In this initialization process, first, in step S112, data stored in a preset area of the RAM 111 is erased. This is because the RAM 111 retains data at the time of power-off or immediately before resetting by a backup power supply, and thus erases data such as a work area. However, data such as the jackpot random number initial value counter and the jackpot random number counter are not erased, but are used after the power is turned on or after restart by reset.

  Next, after setting a stack pointer (S113), setting an initial value in an area of the RAM 111 that requires an initial value such as a jackpot random number initial value (S114), and transmitting a reset command (S115), a CTC (counter In order to start the normal interrupt processing (timer circuit) (FIG. 7), an interrupt timer is set (S116), the interrupt is permitted (S117), and the process proceeds to step S118 (FIG. 6).

  Then, the storage contents of the RAM inspection area are checked (S118), and if the inspection result of the storage contents of the RAM inspection area is abnormal ("NO" in S119), in order to initialize the storage contents of the RAM 111, Returning to step S101, the processes of steps S101 to S103 and S112 to S117 are executed.

  Here, the check of the RAM inspection area means that a predetermined value (for example, 55h) is written in the inspection area of the RAM in step S118, and the data of the inspection area is stored after executing a series of game processes in steps S120 to S127. It is checked whether it remains 55h (whether it is not destroyed) or not.

  On the other hand, if the inspection result of the stored contents of the RAM inspection area is normal (“YES” in S119), normal game processing (S120 to S127) is started.

  In the switch input monitoring process in step S120 of the normal game process, for example, the switch input flag set by the signal input from the port in step S142 of the normal interrupt process (FIG. 7) described later is monitored, and a special symbol start is performed. When the switch input flag of the sensor 52 is set, a process of extracting a winning random number (random number updated / generated in step S140 described later) and storing it in the start storage area of the RAM 111 is executed.

  In step S120, the number of prize balls to be discharged determined for each prize opening is calculated according to the reading results of the detection signals of the general prize opening sensors 51.1 to N, and information on the number of prize balls determined. Is transmitted to the discharge control device 400 as a payout command by the processing of steps S125 and S136 described later, and the stored value of the information on the number of undischarged prize balls is updated (added).

  Furthermore, in step S120, the detection signal of the sensor for detecting the prize balls to be discharged is read, and a process for updating (subtracting) the stored value of the undischarged prize ball number information according to the read result.

  In addition, each switch input flag set by the detection result of the output state of each sensor is set when the result of reading the detection signal of each sensor is the active state (for example, H level) twice continuously. .

  Next, an error monitoring process for monitoring error occurrence / cancellation and setting error information is executed (S121).

  Then, a special game process for a variable display game of identification information displayed on the variable display device (special symbol display device) 8 is performed (S122).

  Specifically, processing for determining whether or not the jackpot random number counter value extracted and stored in step S120 is successful, processing for effect display on the variable display device 8, and the like are performed. If the jackpot random number counter value is a predetermined value, the jackpot state is entered, the identification information stops at the winning symbol, the ON data for the jackpot solenoid 10A is set in the transmission area, and the special game state is started.

  That is, the contents (commands) of control information (commands) to be transmitted to the display control device 150, the decoration control device 200, the sound control device 300, etc. in accordance with the progress of the variable display game displayed in the display area of the variable display device 8. Data).

  Furthermore, a general game process for a variable display game with a normal symbol displayed on the normal symbol display 7 is performed (S123). Specifically, based on the passing of the game ball to the normal symbol start gates 27A and 27B detected by the normal symbol start sensors 53A and 53B, the normal symbol random number counter value stored in the normal symbol winning memory (in step S120) It is determined whether the extracted / stored random number) is a hit or not, and a process for displaying the fluctuation on the normal symbol display 7 is performed. If the normal symbol random number counter value is a predetermined value, it becomes a hit state related to the normal symbol, and the normal symbol stops at the winning symbol (hit number).

  Next, external information editing processing is executed (S124). In this external information editing process, for example, based on the progress state of the variable display game in the variable display device 8, a start signal, a symbol determination signal, a special prize signal, etc. are provided outside the gaming machine, and information from the gaming machine is collected. These signals are set in the transmission area in order to notify the management device (hall computer).

  Then, each command set in step S123 or the like is edited in the order of transmission, and command editing processing (S125) for setting the transmission area is executed.

  Next, in step S126, a random number update process (S126) is performed in which the big hit random number initial value counter is incremented by “1” and each random number value for presentation is also incremented by “1” to update each random number value. .

  In the update of the jackpot random number initial value counter, when the jackpot random number initial value exceeds a predetermined maximum value, a preset minimum value is set, and the jackpot random number initial value is periodically updated between the minimum value and the maximum value. repeat. For example, when the jackpot random number initial value counter is the minimum value “0” and the maximum value “316” as shown in FIG. 10B, “0” is set when the updated counter value becomes “317”. .

  In addition to the special symbol random numbers and ordinary symbol random numbers described above, there are variation pattern selection random numbers for determining variation patterns such as reach modes, etc. as the production random numbers.

  On the other hand, returning to FIG. 5, if it is determined in step S104 that the power failure has been recovered, the process proceeds to step S105, and the power failure recovery processing (S105 to S111) is executed.

  In the power failure recovery processing, first, the stack pointer data stored in the RAM 111 is read and set as the stack pointer data after the power failure recovery in the forced (NMI) interrupt processing (S153 in FIG. 8) described later. After the stack pointer data is recovered (that is, after restoring the stack pointer data), only a specific area to be initialized of the RAM 111 is initialized based on the stored information (S106).

  Next, a command (power restoration command) for notifying that the power supply has been restored to other control devices (display control device 150, decoration control device 200, sound control device 300) other than the discharge control device 400 is transmitted. Processing is executed (S107). Then, the state of the output port is restored to the state at the time of power-off in order to resume the processing (S108). Note that the restoration process of the output port restores the control state of the large winning opening solenoid 10A, the normally variable winning opening solenoid 9A, etc. to the state when the power is shut off, so that the special game state is in effect when the power is shut off. The special game is resumed with the same number of rounds and counts as when a power failure was detected.

  Thereafter, an interrupt timer is started in order to start a normal interrupt process (FIG. 7) using a CTC (counter / timer circuit) (S109). Then, the register data stored in the RAM 111 is read in a forced interrupt process (S152 in FIG. 8), which will be described later, and the data in all the registers is restored (S110). Further, the interrupt status data stored and held in the RAM 111 in the forced interrupt processing (S151 in FIG. 8) described later is read, interrupt permission / prohibition is set, and the interrupt status (permission / prohibition) is set. Is restored to the state at the time of power-off (S111).

  Thereafter, the processing returns to the address (interrupt address) at the time of power-off (when interrupted by forced interrupt). Thereby, the operation of the gaming machine is resumed from the state when the power is shut off.

  FIG. 7 is a flowchart showing a normal interrupt (timer interrupt) process performed in the game control apparatus 100.

  This normal interruption process is started in step S109 or S116 described above, and is executed, for example, every 0.5 milliseconds.

  First, the register data is saved in a predetermined area of the RAM 111 (S131). Next, an output process for setting and outputting the output data set in steps S122 and S124 of the main process described above to the output port is executed (S132). And the process which transmits the control information (command) to the display control apparatus 150 edited by above-mentioned step S125 is performed (S133).

  Next, the value of the time division counter is updated (S134), and the process proceeds to the processing corresponding to the time division counter in the branch processing (S135). For example, when the value of the time division counter whose value sequentially changes in the range of “0” to “7” is “0, 2, 4, 6”, steps S140 to S142 are sequentially executed, and the time division counter When the value is “1”, step S136 is executed, when the value of the time division counter is “3”, step S137 is executed, and when the value of the time division counter is “5”, step S138 is executed. When the value of the time division counter is “7”, step S139 is executed. By such time division, steps S140 to S142 are executed every 1 millisecond, and steps S136 to S139 are executed every 4 milliseconds.

  In step S140, the game random numbers such as the jackpot random number counter, the jackpot random number initial value counter, the special symbol random number, the normal symbol random number, and the variation pattern selection random number are increased by “1” to update each random number value. .

  The update of the jackpot random number initial value counter is the same as in step S126 described above. When the jackpot random number initial value exceeds a predetermined maximum value, a preset minimum value is set, and a period between the minimum value and the maximum value is set. Repeat the update of the initial value of the jackpot random number.

  On the other hand, the update of the jackpot random number counter is set to the minimum value “0” when the jackpot random number exceeds a predetermined maximum value (for example, 316), and when the jackpot random number reaches the initial value (the start value of this round), the jackpot random number initial value is set. The value of the value counter is read, and this value is set as a new initial value of the jackpot random number counter.

  For example, when the jackpot random number initial value counter and the jackpot random number counter are the minimum value “0” and the maximum value “316” as shown in FIGS. 10A and 10B, the current round of the jackpot random number counter is “315”. When the updated jackpot random number counter value reaches “315”, the value “11” of the jackpot random number initial value counter at that time is read, and this “11” is the new initial value of the jackpot random number counter. Set as For this reason, the jackpot random number initial value counter and the jackpot random number counter are configured with the same minimum value and maximum value.

Next, timer update processing 1 is executed to generate a reference time (1 millisecond) for use in each processing of the main processing (S141).
Subsequently, port input processing (switch reading processing) is performed (S142). The port input process is a process of reading a signal input to each input port of the gaming CPU 110. That is, each sensor (special drawing start sensor 52, universal drawing start sensor 53A, 53B, general winning opening sensor 51.1-51.N, half-end sensor, overflow sensor, glass frame opening sensor, prize ball detection sensor, etc.) Read the detection signal. Specifically, the output value of each sensor is determined every 1 millisecond, and when the output value of the same level continues for a predetermined number of times (for example, twice), the level of this output value is set to the detection signal of each sensor. By reading as a deterministic value, erroneous determination due to temporary fluctuation (chattering) of the sensor is prevented.

  In steps S136 to S138, control information (command) is transmitted to each control device edited in step S126 described above. That is, a payout command is transmitted to the discharge control device 400 (S136), a voice command is transmitted to the sound control device 300 (S137), and a lamp command is transmitted to the decoration control device 200 (S138).

  Also, the timer update process 2 is executed to generate a reference time (4 milliseconds) for use in each process of the main process (S139).

  Next, in order to resume the main process, the value of the register saved in step S131 is restored (S143), the interrupt is permitted (S144), and then the process is interrupted by returning to the process interrupted at the time of the interrupt. Resume processing.

  FIG. 8 is a flowchart showing a power failure process performed in the microprocessor of the game control apparatus 100. This process is forcibly started by interrupting the process being executed using the power failure detection signal output from the power failure monitoring circuit as an NMI interrupt signal.

  When the power failure detection signal is input and power failure detection processing (NMI interrupt processing) starts, the timer interrupt enable / disabled data, all register values, and stack pointer data before the NMI interrupt occurrence are saved. Then, it is stored in a predetermined area of the RAM 111 being backed up (S151 to S153).

  Next, off data is output to all output ports, and the output of all ports is turned off (S154). Then, after setting a power failure flag in the power failure inspection area of the RAM 111 and prohibiting access to the RAM 111 (S156), the CPU 111 waits without performing any processing such as computation and input / output, and enters a reset signal input waiting state. .

  Here, the process of waiting for the operating state of the gaming CPU 110, turning off the output of the port, prohibiting access to the RAM 111, and waiting until the gaming CPU 110 stops hardware operation by the reset signal. In the meantime, the function is substantially stopped (the operation is stopped by software), and an undefined signal is output or undefined data is erroneously written into the RAM 111 with high reliability. Also, in the process of saving and saving all data such as all registers and stack pointers, the operation returns to the same state (game state, game control state, discharge control state, etc.) as when the power is turned off after power is restored, It can be resumed from the state of.

  FIG. 9 shows a subroutine for initialization processing of the jackpot random number initial value counter performed in the microprocessor of the game control apparatus 100, and this processing is executed in step S114 of FIG.

  In step S161, the jackpot random number initial value stored in the backup area of the RAM 111 is read. In this case, the jackpot random number initial value is composed of 2-byte data.

  Next, in step S162, predetermined bits are cleared with a preset mask for the read jackpot random number initial value. Here, 000FH is used as an example of the mask, and the upper 4 bits of the upper byte and the lower byte are cleared.

  In step S163, a value obtained by clearing the upper 4 bits of the upper byte and the lower byte by the mask is stored as a new jackpot random number initial value in a predetermined area of the RAM 111, and the initial value of the jackpot random number counter immediately after startup is stored. Set as ending. As a result, in the normal processing of FIG. 6, the value of the big hit random number initial value counter used in the first loop becomes the value obtained by stirring the value at the previous power-off or reset time with the mask, and the big hit for performing the big win lottery Since the random number counter starts updating from this value, the initial value of the jackpot random number counter can be agitated randomly each time the game control device 100 is activated.

  Here, the value set in the mask is set to a value that does not exceed the maximum value of the jackpot random number initial value counter. For example, the jackpot random number initial value counter and the jackpot random number counter are set to 0 as shown in FIG. In the case where 316 is repeated periodically, for example, if the mask value is set to a value less than 00FFH, the value of the jackpot random number initial value counter immediately after the start of the game control device 100 is set randomly within the range of 0-255. And does not exceed a predetermined maximum value.

  With the above processing, in the normal game processing, steps S118 to S126 of FIG. 6 are repeatedly executed, and the big hit random number initial value counter is incremented by “1” in one loop (S126). In the 1-ms timer interruption, the big hit random number initial value counter and the big hit random number counter are each incremented by “1”.

  The jackpot random number initial value counter is set to a minimum value when a predetermined maximum value is exceeded, and this is periodically repeated. When the jackpot random number counter exceeds a predetermined maximum value, the jackpot random number initial value is read and set as a new update start position, so that updating of the random number is started from a random initial value every round.

  As a result, in a normal game, even if the fraudster determines the update timing of the jackpot random number counter, the value of the jackpot random number counter cannot be captured unless the initial value stirring of each lap is analyzed. It becomes extremely difficult to perform an illegal act that generates a gaming state (a jackpot).

  On the other hand, when the reset signal is artificially given to the game control apparatus 100 by the above-described illegal board or the like, the CPU 110 is restarted and the initialization process from step S112 to step S117 in FIG. 5 is performed.

  Then, the RAM 111 erases the RAM except for random numbers such as the big hit random number initial value counter, and then performs the mask process of FIG. 9 in step S114 to randomly set the big hit random number initial value after reset. By setting and starting the update of the jackpot random number on the first round with this value, the initial value of the big hit random number is agitated from the first round immediately after startup to prevent the value of the big hit random number from being supplemented It is possible to prevent an illegal game due to an artificial reset.

  That is, as shown in FIG. 10, when the value of the jackpot random number counter immediately before the artificial reset is “315”, in the mask process of FIG. 9 executed in the initialization process, 2 bytes by the mask of 000FH The upper 4 bits of the big hit random number initial value counter and the upper 4 bits of the lower byte are cleared and the lower 4 bits are set as the initial value. In this case, “11” is obtained, and this value is set as the big hit random number initial value counter and the big hit random number counter. In the first round immediately after startup, the update of the jackpot random number is started from the randomly generated initial value “11”.

  Further, even if the unauthorized person continuously generates reset signals and the contents of the RAM 111 are destroyed, the RAM inspection area check in step S119 is restarted, and the jackpot random number initial value counter in step S114 In this setting, since a mask that does not exceed a predetermined maximum value is used, the contents of the destroyed RAM 111 can be used as a random number, and the illegal game immediately after starting can be made extremely difficult as described above. .

  Note that the random setting of the initial value of the jackpot random number immediately after startup may be by hardware. For example, the operation clock is output according to the oscillation frequency determined by the resistance value of the resistor and the capacitance value of the capacitor. An astable multivibrator circuit and an IC (random number IC) that updates (generates) a random value by a predetermined algorithm based on reception of the operation clock, and the value obtained from the random number IC is used as the initial value of the jackpot random number immediately after startup. It may be a value.

  In addition, the initial setting of the jackpot random number immediately after startup is performed by adding the values of all the registers of the CPU 110 (refresh registers, general-purpose registers, etc.) and performing mask processing so that this value is less than a predetermined maximum value. A value may be used.

  FIG. 11 shows the second embodiment and is another example of jackpot random number agitation. When all of the RAM 111 is cleared to 0 by initialization at startup, when the big hit random number becomes a predetermined value in the first round of the big hit random number immediately after startup, it is skipped to a predetermined value at which stirring is started. is there.

  Similar to the conventional example, in the initialization process, when all the areas of the RAM 111 are cleared with a predetermined value (for example, 0), the jackpot random number is updated (incremented) from 0.

  Then, before the value of the jackpot random number becomes a predetermined value (for example, “7”) indicating the jackpot (specific game state), a predetermined maximum value (“316”) or a preset value (for example, “ 315 "), the jackpot random number is updated.

  For example, when the jackpot random number that started addition from 0 becomes “6”, it is skipped to “316”, and becomes “0” in the subsequent update of the random number, and the first round is completed. At this time, the initial value of the jackpot random number is agitated by the value of the jackpot random number initial value counter.

  As a result, even when all of the RAM 111 is cleared by initialization at the time of startup, the jackpot random number in the first round immediately after startup is skipped to the maximum value or its vicinity before reaching the value indicating the jackpot, The value of the jackpot random number can be agitated by the random number initial value counter, and even if cheating by artificial reset is performed, it becomes very difficult to supplement the timing of the jackpot from the outside, Suppression can be achieved.

  The same applies even if the agitation condition is set so that only the first round of the jackpot random number after the reset is executed before the value indicating the jackpot is reached. For example, one round after the reset By setting the agitation condition so that the agitation is performed with the big hit random number being “5” (a value less than the big hit determination value “7”), it becomes difficult to supplement the timing of the big hit from the outside.

  FIG. 12 shows the third embodiment, and shows a case where all the areas are cleared to 0 by the RAM initialization process as in the second embodiment.

  FIG. 12 is an example of a flowchart of processing performed in the game control apparatus 100, and shows normal processing from startup.

  The CPU initialization in step S100A indicates the processing of steps S101 to S103 shown in FIG. 5 of the first embodiment, and step S104 also determines whether to recover from a power failure as in FIG. When the power is restored, the process proceeds to step S105A, and the processes from S105 to S111 in FIG. 5 are performed.

  On the other hand, the RAM initialization process of step S112A is performed at the time of normal power-on or reset. The RAM initialization process here is to clear the entire area of the RAM 111 with a predetermined value, and the others are the same as steps S113 to S117 in FIG. However, in the initial value setting in step S114, “0” is set for both the big hit random number initial value counter and the big hit random number counter.

  When initialization is completed, dummy processing is performed in step S200. This dummy process is executed until the update of the big hit random number immediately after the start is completed and the random number is stirred by the big hit random number initial value counter.

  Specifically, the processing from steps S118 to S126 of FIG. 6 and the timer interruption of FIG. 7 are performed, but the winning ball is not acquired (lottery) even if the game ball enters the start port 16, without winning. It is assumed that only discharge of

  Then, when the big hit random number counter makes one round and the update (stirring) by the big hit random number initial value counter is performed, the dummy process is finished, the normal process of step S120A is executed, and the normal game control is started. Note that step S120A is the same as the processing of steps S118 to S126 in FIG.

  In this case, in order to limit the acquisition of the value of the jackpot random number counter until the jackpot random number counter initialized to the initial value by the reset is agitated, the fraudster has determined the initial value and the update timing. However, it is difficult to capture from the outside the timing at which the value of the jackpot random number is updated to a value that causes the specific gaming state. Even if the acquisition of the jackpot random number is limited in this way, it takes a sufficiently long time from the start of the reset to the detection of the predetermined event based on the player's operation compared to the update of the jackpot random number counter. However, even if the acquisition of the jackpot random number counter value during this period is limited, there is very little possibility of causing a disadvantage to the player.

  Alternatively, in the dummy process, the switch input monitoring (S120) may not be performed until the jackpot random number counter makes one round. In this case, since no input is performed, the start from the start port at the jackpot timing. Even if the detection signal is input, it will be ignored, and fraudulent acts immediately after resetting can be suppressed. Even if switch input is performed, the detection result may not be stored.

  In addition, in the dummy process, the value used for the lottery is fixed to the off-set value until the jackpot random number counter initialized to the initial value by the reset is agitated, thereby preventing illegal acts immediately after the reset. May be.

  In the dummy processing, until the big hit random number counter makes one round, the big hit random number counter is updated (stirred) when there is a physical input, for example, a winning at the start port 16 or the like. Also good.

  That is, as shown in FIG. 17, in the input processing of the gaming machine (for example, the start port 16), the detection switch is monitored with 1 msec as one frame, and further, in order to prevent chattering and noise, two frames continuously. When the input signal is at the Hi level, the detection value is turned ON, and operations such as obtaining a big hit random number are performed.

  Therefore, in the dummy process, if the big hit random number is stirred at the rising edge of the input signal, the big hit random number is acquired in the next frame 5 because the agitation is executed in the frame 4 in FIG. Even if a person sends the start port detection signal at the jackpot timing immediately after the reset, the occurrence of a specific gaming state can be suppressed.

  Further, as shown in frame 2 in FIG. 17, the jackpot random number may be agitated by noise or the like in which the input signal becomes Hi level for only one frame.

  Further, as an example of the dummy processing, the jackpot random number counter may be incremented up to the maximum value (upper limit value). In this case, the jackpot random number counter is updated at the same time as entering the normal game control (S120A). Therefore, when a normal game is started, agitation is performed immediately, and it is difficult to capture the value of the jackpot random number counter from the outside.

  FIGS. 13 and 14 show the fourth embodiment. When an unauthorized reset signal is detected, the fraud notification unit provided in each of the decoration control device 200 and the sound control device 300 notifies that there is a risk of fraud. Is.

  FIG. 13 is an example of a flowchart of processing performed in the game control apparatus 100, and shows normal processing from startup.

  The CPU initialization in step S100A indicates the processing of steps S101 to S103 shown in FIG. 5 of the first embodiment, and step S104 also determines whether to recover from a power failure as in FIG. When the power is restored, the process proceeds to step S105A, and the processes from S105 to S111 in FIG. 5 are performed.

  On the other hand, at the time of normal power-on or reset, it is determined in step S201 whether or not it is an unauthorized reset, in other words, whether or not the reset includes a power-off operation, and when only a reset signal is generated, It judges that it is fraud, and progresses to step S202, and performs fraud notification by the decoration control device 200 and the sound control device 300.

  Thereafter, RAM initialization processing in step S112A 'is performed. The RAM initialization process here is the same as in the first embodiment.

  Next, when the initialization is completed, the normal process of step S120A is executed, and normal game control is started. Note that step S120A is the same as the processing of steps S118 to S126 in FIG.

  The fraud notification unit of the decoration control device 200 includes a decoration device (such as a lamp) 31A that is independent of the decoration (first notification lamp) 31 used in a normal game. Similarly, the fraud notification of the sound control device 300 is performed. The department also has a decoration device 31A that is independent from the speaker 95 used in the normal game, and notifies the employee of the fact that there is a risk of fraud or the risk of the fraud.

  This notification period may continue for a predetermined time (several tens of minutes) or until the power supply is normally shut off, and by making it independent from normal gaming, the notification is continued regardless of the progress of the game. Is possible.

  Alternatively, the above notification may be performed when a reset occurs after the power is turned on.

  In addition, when the sound control device 300 or the decoration control device 200 receives a command from the game control device 100 that causes the content related to the notification to disappear during the notification period, the command is invalidated to prevent fraud. Invalidation of notification can be suppressed. Note that if the command is such that the information regarding the notification does not disappear, the control of sound and decoration is executed according to the received command.

  FIGS. 15 and 16 show the fifth embodiment, in which a reset signal line is made independent from the cable 101 connecting the power supply device 250 and the game control device 100 shown in FIG. 3 of the first embodiment, and the reset signal Are connected by an optical fiber 701.

  15 and 16 show the connection state of the cable 101 (electrical connection means) and the optical fiber (optical connection means) 701 on the power supply device 250 side, and the game control device 100 is similarly configured.

  The cable 101 configured by a flat cable or the like includes a power failure detection signal line, a power supply line, and the like, and is connected to the substrate via the connector 252 as in FIG. 3 of the first embodiment.

  The optical fiber 701 is connected to the photoelectric conversion unit 700 on the substrate via the connector 702. This photoelectric conversion unit 700 converts an electrical reset signal into light such as a semiconductor laser or LED and transmits it to the game control device 100.

  Since the reset signal line is composed of the optical fiber 701, the optical fiber 701 is cut to attach an unauthorized substrate and an unauthorized device is interposed, but an optical fiber is separately connected to the cut optical fiber 701. This requires a work of joining the clads to each other by work such as fusion, which is a large-scale work, and it is difficult to attach an unauthorized substrate easily and quickly. In addition, an illegal substrate that transmits an optical signal requires an optical system, so that it is difficult to reduce the size, and even if it is successfully mounted, it can be easily found.

  Moreover, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
