Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a gaming machine such as a pachinko machine, an arrangement ball machine, a sparrow ball game machine, and a revolving game machine, and more particularly to one that copes with an illegal act that illegally generates a jackpot lottery.
[0002]
[Prior art]
  Conventionally, in ball game machines such as the first type of pachinko machines, the gate means (passing means) for starting normal symbols, special symbol starting means (electric tulips), or one or more ordinary symbols are changed on the game board. Normal symbol display means that can be displayed, special symbol display means that can variably display a plurality of special symbols, and variable winning means (opening and closing type winning means) called attackers, etc., and the player operates the launch handle of the launch means As a result, the game balls stored in the ball tray are sequentially launched into the game area of the game board.
[0003]
  And when the launched game ball falls with the game nail or windmill changing the falling direction and wins the special symbol starting means, a plurality of special symbols on the special symbol display means fluctuate for a predetermined fluctuation time, If the result of the lottery at the time of winning the special symbol starting means is a big win, the stop symbol after the change becomes a specific symbol mode (so-called “777” big hit symbol mode), and the variable winning unit is based on a predetermined condition. Thus, the opening / closing operation is repeated up to a set number of times (for example, 16 rounds), and a special game that is in a profit state advantageous to the player occurs.
[0004]
  By the way, in the main control means that controls game control on the game board side, for example, a plurality of control random numbers from “0” to “299” are set as a round value, and “0” → “1” → “2” → ... → A random number generator that repeatedly generates a control random number of “299” with a minute update period (for example, about 2 msec), a random number extractor, a random number determiner, and the like are provided. The control random number at the time of winning the symbol starting means is extracted by the random number extracting means, and the extracted control random number is checked by the random number determining means with the jackpot determination symbol (for example, “17”) to determine whether or not it is a big hit It is supposed to be.
[0005]
  In this case, utilizing the fact that a big hit determination symbol such as “17” is periodically generated, the big hit cycle is read, and the special ball starting means is regularly awarded to the special symbol starting means at the timing of the big hit cycle. As a result, a player who has greatly improved the jackpot lottery and gains a large profit has appeared. Therefore, recently, each time the control random number generated by the random number generation means makes a round, a new starting value (so-called round initial value) for starting a round is generated randomly by the separately provided round initial value generation means. In addition to updating to the initial value and simultaneously updating the jackpot determination symbol in accordance with the update of the initial round value, the periodicity of the jackpot lottery is eliminated so that the target of the jackpot cannot be made.
[0006]
  However, when the power is turned on at the start of business on the pachinko hall side, a system reset signal is always generated by the power-on reset signal at the time of power activation in the microcomputer included in the control device for the main control means. Therefore, the random number generation by the random number generation means always generates a control random number sequentially from the first numerical value “0” of the cyclic value, and the jackpot determination symbol is determined in advance as a default value, such as “17”. It is controlled to set to the value of.
[0007]
  By the way, for example, when a power failure occurs due to a lightning strike, the control device does not operate at the same time, and even if a jackpot game is being executed, jackpot information and winning ball number information instructing that it is a jackpot state All of the various game information such as the payout ball number information to be paid out is deleted. Therefore, when the game is resumed after recovery from the power failure, the jackpot game cannot be executed in a state immediately before the power failure, and trouble may occur between the player and the hall side.
[0008]
  Therefore, recently, the game information during the game is always stored and retained by the backup power source, and even if a power failure occurs, it can be resumed without any trouble from the middle of the game control interrupted by the power failure when returning from the power failure. ing. In this case, the RAM included in the main control microcomputer is always backed up by a backup power source, and a backup dedicated memory area is provided in a part of the RAM.
[0009]
  By doing so, an NMI (non-maskable interrupter) is generated in the CPU of the main control microcomputer in the event of an abnormal situation where a power failure has occurred, and each register and stack pointer of the main control CPU are generated by the NMI. Backup processing for saving and storing the value, game information, etc. in the backup dedicated memory. And at the time of recovery from a power failure, by executing a recovery process that writes the stored information stored in the backup dedicated memory to each predetermined memory, it is possible to resume the game control interrupted by the power failure following the state immediately before the power failure. I can do it.
[0010]
[Problems to be solved by the invention]
  As described above, in the conventional ball game machine, when the round number is repeatedly generated by the random number generation means, the round initial value and the jackpot determination symbol are sequentially updated every time the control random number is generated. However, Goto et al. Have crafted them with a so-called hanging method to illegally send a system reset signal to the main control CPU constituting the main control means. generate. Therefore, the value of the program counter is reset, and the game control is executed from the beginning.
[0011]
  As a result, as described above, the first numerical value in the first round of random number generation is set to the default “0”, and the jackpot determination symbol is also set to a predetermined numerical value. Since the control random number is generated in the first round after the system reset, it is possible to deliberately hit the big win lottery by matching the winning timing to the special symbol starting means with the big win lottery. An object of the present invention is to make it possible to reliably prevent the hitting of the big hit lottery that caused an unauthorized system reset by Goto and the like.
[0012]

To be achieved.
[0034]
  The main control means 50 configured on the main control board 39 controls the game operation according to the game mode and the behavior of the game ball, that is, various game parts 20 and 21 provided on the game board 5 and various game balls. While mainly controlling the game control of the game board 5 related to the input / output of signals to the game ball detection switch provided in the detection means 18 to 21 etc., the symbol control means 60, the payout control means 70, the lamp control means 71, which will be described later, A control command is transmitted and output to the sound control means 73 or the like as necessary.
[0035]
  The symbol control means 60 configured on the symbol control board 40 variably controls the normal symbols of the symbol display units 24a and 24b based on the symbol control command transmitted from the main control means 50, and the normal The variable stop is controlled so as to display the symbol form. The symbol control means 60 further controls variation of the special symbols of the symbol display units 23a to 23c based on the received symbol control command, and controls variation stop so as to display the designated special symbol mode. The effect display control for effect display on the screen of the liquid crystal display 16 including these symbol display units 23a to 23c is executed.
[0036]
  The payout control means 70 configured on the payout control board 46 receives a payout control command from the main control means 50 and controls payout of the game ball by the payout means 35. The lamp control means 71 configured on the lamp control board 42 receives a lamp control command from the main control means 50, and displays a large number of decorative lamps, effect lamps, etc. provided on the game board 5, the front frame 4, and the like. It controls lighting control of the lamp group 72 including it.

  The sound control means 73 configured on the sound control board 43 receives a sound control command from the main control means 50 and drives and controls a speaker 74 provided on the back side of the ball tray 8 to control sound output. Launch control means configured on launch control board 4849Controls the launch of the game ball by driving the launch motor 13. Here, the external output board 32 transmits and outputs the number of times of change related to the special symbol, information on the stop symbol, and the like to an island computer (not shown) provided in the pachinko hall.
[0038]
  The main control means 50 includes special symbol random number generation means 51 and random number extraction means 52, random number determination means 53, profit state generation means 54, symbol determination means 55, command transmission means 56, and 2 msec signal generation means. 57 etc. Here, the random number generating means 51, the random number extracting means 52 and the like constitute a lottery means for special symbols. The main control means 50 is separately provided with a normal symbol lottery means for performing a lottery with respect to a normal symbol based on the passing of a game ball through either of the left and right gate means 18. A description of the lottery means will be omitted, and the special symbol lottery means will be described.
[0039]
  Next, the random number generating means 51 and the random number extracting means 52 of the special symbol lottery means will be described. The random number generation means 51 repeatedly generates control random numbers from, for example, “0 to 299” in a minute update cycle (for example, about 2 msec). Of the plurality of control random numbers generated by the random number generation means 51, only one control random number (for example, “17”) is set as a jackpot determination symbol that is a predetermined specific random number.
[0040]
  The random number extraction means 52 extracts one control random number when the game ball wins the special symbol starting means 20 with respect to the special symbol. Since the random number determining means 53 extracts one control random number by the random number extracting means 52 when the game ball wins the special symbol starting means 20, the random number determining means 53 determines the specific random number for the special symbol at the time before the change of the special symbol. It is determined whether it is a matched “big hit” or “out (including out of reach)”.
[0041]
  Furthermore, the random number determination means 53 also determines the probability variation type jackpot, and if it is determined to be the probability variation type, after the special game in the profit state ends, until the next or one after another jackpot Alternatively, the number of specific random numbers that are jackpots is made larger than usual until the special symbol fluctuates a predetermined number of times (for example, 100 times). That is, the jackpot probability is higher than usual. Further, the random number determination means 53 instructs the profit state generation means 54 described later to give a predetermined profit in the case of such a probability variation. This is also a profit state advantageous to the player.
[0042]
  The profit state generating means 54 receives a determination result of the jackpot from the random number determination means 53, or the predetermined profit included in the game control on condition that the stop symbol after the change of the special symbol display means 23 becomes a jackpot symbol. The open / close plate 21a of the variable winning means 21 is opened / closed as described above by the state generation routine. Further, when the profit state generating unit 54 receives the above-described probability variation instruction from the random number determining unit 53, the profit state generating unit 54 sets the opening / closing claw 20a of the special symbol starting unit 20 at a normal time (for example, on the condition that the normal symbol is “winning”) (for example, , About 0.5 seconds) (for example, about 3 seconds), the player is provided with a profit state in which the game ball can easily enter, for example, by opening.
[0043]
  In accordance with the determination result from the random number determination means 53, the symbol determining means 55 determines the winning normal symbol and the winning normal symbol variation pattern by lottery when “winning” is determined for a normal symbol by a predetermined lottery program. In the case of “out”, the off-normal symbol and the off-normal symbol variation pattern are determined by lottery. The symbol determination means 55 further determines the special bonus and special bonus variation pattern for the big bonus by lottery for the special symbol by lottery, and determines the special special symbol variation and the special symbol variation pattern for the special bonus when it is “out”. To do.
[0044]
  Based on the variation pattern determined by the symbol determination unit 55, the command transmission unit 56 provides the symbol control unit 60 with a variation pattern designation code for designating a variation pattern number for a special symbol, a stop symbol, Not only the stop command is transmitted and output as a control command for each symbol variation, but also various control commands including a variation pattern designation code are transmitted to the symbol control means 60 for the variation pattern of the normal symbol in the same manner. The command transmission means 56 further transmits various control commands accompanying the symbol variation to the payout means 35, the lamp control means 71, the sound control means 73 and the like as required.
[0045]
  The 2 msec signal generation means 57 is a CPU 75 included in the microcomputer 39A.(Calculation processing means)The clock signal to be supplied is divided to generate an interrupt signal every 2 msec, and a periodic interrupt signal every 2 msec is supplied to the interrupt port of the CPU 75. The main game control is periodically executed by the periodic interruption every 2 msec.
[0046]
  The symbol control means 60 includes a special symbol control means 61 for controlling the special symbol display means 23, a normal symbol control means 62 for controlling the normal symbol display means 24, a variation pattern storage means 63, etc., and a command transmission means 56. The symbol control command transmitted from is received and the received symbol control command is analyzed. In the symbol control means 60, the special symbol control means 61 controls the special symbol variation in each symbol display section 23a-23c, and the normal symbol control means 62 controls the normal symbol variation in each symbol display section 24a, 24b. The fluctuation pattern storage means 63 stores fluctuation pattern information in which fluctuation contents (including fluctuation time) are associated with each of a plurality of fluctuation pattern numbers with respect to normal symbols and special symbols.

  The stack area 77c stores an address and the like for a subroutine call. The backup information memory 77d stores various backup information necessary for resuming the game control when the main power is cut off when the power is restored. Here, the RAM 77 of the microcomputer 39A and the RAM 81 of the microcomputer 46A are supplied with backup power from a backup power supply 93, which will be described later, and all the storage information of these RAMs 77 and 81 is stored and held. A game operation control program is mainly stored in the program area of the ROM 76.
[0051]
  The game operation control program will be described. As shown in FIG. 8, a first control routine for game control preparation and a second control routine for game control are stored in advance. In the first control routine, an initial setting subroutine 76a, a reset subroutine 76b, a backup information return subroutine 76c, an abnormal state notification subroutine 76d, a game operation stop subroutine 76e, and the like are stored in advance. The second control routine includes a game control subroutine 76f that is a main control, a time adjustment subroutine 76g for periodically executing the game control subroutine 76f, a backup processing subroutine (this corresponds to a backup processing section) 76h, and the like. Is stored in advance.
[0052]
  Incidentally, as described above, the payout control board 46 has a microcomputer 46A for controlling payout control by the payout control means 70, and this microcomputer 46A includes a CPU 79, a ROM 80, a RAM 81, and the like. The RAM 81 is provided with a work area and the like in the same manner as the main control RAM 77. The work area is provided with a payout control information area, a stack area, a backup information memory, and the like. The ROM 80 stores a payout control subroutine, a backup data restoration subroutine, a backup processing subroutine, and the like, which are main controls, as in the case of the main control ROM 76, but detailed description thereof is omitted here.
[0053]
  Next, the power supply board 45 supplies power to each of the plurality of control boards 39, 40, 43 to 46, and the power supply means 45A configured on the power supply board 45 will be described.
  As shown in FIG. 9, a plurality of transformers 94 are provided for each island structure installed in the pachinko hall, and a plurality of (for example, five) low-voltage AC voltages (AC24V) are provided from each transformer 94. It is supplied to the pachinko machine 2 at the same time.
[0054]
  The power supply means 45A includes a power switch 85 which is a toggle switch and can be turned on and off by manual operation, a power supply means 90, a power supply monitoring means 91 and a reset signal generating means 92 which are made of a microcomputer. A backup power supply 93, a push-type reset switch 86, and the like are provided. The power supply means 90 generates DC32V from AC24V, DC12V used for sound output and lamp lighting, and DC5V supplied to control units such as the microcomputers 39A and 46A, and these direct currents are connected to the control board via a wiring cord. Power is individually supplied to 39 to 40, 42 to 43, 46, and the like.
[0055]
  The power monitoring means 91 directly reads the AC 24V supplied via the power switch 85 and constantly monitors the supply voltage, and when a power failure occurs or when the main power is cut off by the power switch 85 being turned off, When any voltage abnormality is detected in the power supply, an “L” level voltage abnormality signal VS indicating the voltage abnormality is output to the highest priority interrupt port “NMI (non-maskable interrupter) port” of the microcomputers 39A and 46A, respectively. . Therefore, the game control is substantially interrupted by the microcomputer 39A, and various types of information that needs to be stored and stored, such as the CPU 75 register and stack pointer values, information on winning and paying out game balls, etc., are backed up with the highest priority. Is done.
[0056]
  Also, with the payout control mancon 46A, as in the main control, the payout control is substantially interrupted, and various information that needs to be stored is backed up with the highest priority. The reset signal generation unit 92 is delayed by a predetermined minute time (for example, about 120 msec) required for the backup process from the time when the voltage abnormality signal VS of the “L” level is received from the power supply monitoring unit 91 to the “L” level. The switched system reset signal SR (L) is output to the delay means 78 and each of the CPUs 79, 82 to 84, while the system reset signal SR (H ) Is output.
[0057]
  Here, the main control board 39 is provided with a delay circuit 78, and when a system reset signal SR (L) that switches to the “L” level is received at the time T1, as shown in FIG. At the time T1, the system reset signal SR (L) is supplied to the microcomputer 39A at the same time, but at the time T2, the system reset signal SR (H) that switches to the “H” level is received. In this case, the system reset signal SR (H) is supplied to the microcomputer 39A at a time T3 which is delayed by a predetermined minute time t from the time T2.
[0058]
  Therefore, when the system reset signal SR (L) is simultaneously supplied to the reset terminals of the CPUs 75, 79, 82 to 84, the control operations are stopped with the initialization of the CPUs 75, 79, 82 to 84, respectively. . However, when the reset signal generator 92 outputs the system reset signal SR (H) when the main power supply is restored, only the CPU 75 starts the game control with a delay of a predetermined minute time t from the other CPUs 79 and 82 to 84. Is done.
[0059]
  The backup power source 93 is composed of a charging capacitor or the like, and always supplies DC5V output from the capacitor to both RAMs 77 and 81 for backup. Therefore, even when the main power supply is cut off, all stored information in the RAMs 77 and 81 including the backup information memory 77d is continuously stored and held. However, the backup operation of both RAMs 77 and 81 by the backup power supply 93 can be continued for a long time.
[0060]
  A reset switch 86 is provided on the power supply board 45 so as to be close to the power switch 85. When the reset switch 86 is pressed with a finger at the same time as the main power is turned on by the power switch 85, the reset switch 86 outputs “L”. "Level reset signal (erase signal CL) is simultaneously output to the reset terminals of the CPUs 75 and 79. As a result, all the RAMs of the microcomputers 39A, 40A, 42A, 43A, and 46A can be simultaneously reset to erase data.
[0061]
  By the way, although not shown, the smoothing circuit of the generating circuit that generates DC 32V is provided with a large-capacity smoothing capacitor, and as shown in FIG. The lower limit setting voltage VL (for example, about 6-7V) which is the minimum setting voltage that can maintain the DC5V generation from the time when the main power supply is cut off and AC 24V is not supplied to the power supply means 90 and the voltage abnormality is detected. It is possible to secure about 120 msec until it decreases. That is, the backup process described above can be reliably executed in the main control means 50 and the payout control means 70 within about 120 msec.
[0062]
  Here, a power supply abnormality detection circuit 95 that detects a voltage drop abnormality of backup power supplied from the backup power supply 93 will be described with reference to FIG.
  The control voltage Vc (5 V) is applied to the input terminal D of the D flip-flop (DF / F) 96, the output signal of the OR gate 97 is supplied to the clock terminal CK, and the backup voltage Vb is supplied to the OR gate 97. And a clock pulse CLK are supplied. An output signal Sb from the output terminal Q of the DF / F 96 is supplied to the input port of the CPU 75. A system reset signal SR is supplied to the reset terminal RST of the DF / F 96.
[0063]
  Therefore, as shown in FIG. 13, even when the main power supply is turned off, only the backup voltage Vb is always at the “H” level. Therefore, when the main power supply is turned on, the control voltage (5 V) Vc is The signal rises to the “H” level and the clock pulse CLK is also supplied, but the output signal from the output terminal Q remains at the “L” level. However, when the backup voltage Vb is interrupted even for a moment, the output terminal Q becomes “H” level at the rising timing of the clock pulse CLK, and the power supply abnormality signal Sb supplied to the input port of the CPU 75 is Since it is at “H” level, it is possible to detect an abnormality in the backup voltage Vb.
[0064]
  Next, game operation control executed by the main control means 50 will be described based on the flowchart of FIG. However, the symbol Si (i = 11, 12, 13,...) In the figure is each step.
  At the start of business, when the power switch 85 is switched on while pressing the reset switch 86 while the front frame 2 of the pachinko machine 2 is opened forward, the main power is turned on to the pachinko machine 2. In this case, as described above, due to the operation of the delay circuit 78, this game operation control is started after a predetermined minute time t from the control start timing by the other control means 60, 70, 71, 73.
[0065]
  That is, an alternating voltage (AC 24 V) from the transformer 94 is supplied to the power board 45 via the power switch 85, and a direct current from the power supply means 90 is supplied to the control boards 39 to 40, 42 to 43, and 46, respectively. At the same time, the system reset signal SR (H) is simultaneously supplied from the reset signal generating means 92 to the delay circuit 78 and the microcomputers 40A, 42A, 43A, 46A, and the control operation by these microcomputers 40A, 42A, 43A, 46A is started. After that, the game operation control is started by the microcomputer 39A with a delay of a predetermined minute time t.
[0066]
  As described above, when the reset switch 86 is operated when this control is started (S11: Yes), first, initialization for initializing each memory and register of the CPU 75 of the microcomputer 39A is executed. (S12). Next, game control information other than jackpot related information in the game control information area 77a is reset (erased) (S13). That is, in the erasing step of S13, in FIG. 7, in the game control information area 77a, “big hit extraction random number” stored in addresses “0000H” to “0009H”, “initial value update random number”, Only the other game control information stored at addresses “000AH” to “00FFH” other than the “previous initial value random number” and the “big hit symbol determination random number” are deleted.
[0067]
  Next, various initial values are set, such as setting an initial symbol to be displayed on the symbol display means 22 and setting a control cycle for repeatedly executing the main game control subroutine of S23 to S32 by interruption to "2 msec". (S14). Next, in the remaining time until the predetermined control period “2 msec” is reached, the initial value random number generation processing (S15) and the main loop random number generation processing (S16) are repeatedly executed.
[0068]
  Here, in the initial value random number generation process, every time the control random number (1 to 299) generated by the random number generation means 51 makes a round, for example, the random number is updated from “0 to 299”, and the following This is a process for determining a starting value (so-called initial value for one round) for starting one round. Further, in the random number generating process in the main loop, for example, a left symbol, a middle symbol, and a right symbol are selected and determined to be randomly updated from the numerical values “0 to 19” and stopped at the next disconnection. It is processing. In this way, the processing time is adjusted by repeatedly executing S15 and S16 for the remaining time from the start of control until about 2 msec elapses.
[0069]
  By the way, during execution of S15 to S16, about 2 msec has elapsed from the start of control, and a 2 msec interrupt signal is supplied from the 2 msec signal generating means 57 to the CPU 75 as an internal interrupt. As a result, the processing time adjustment routine of S15 to S16 is forcibly stopped halfway, and the main game control subroutine of FIG. 15 is executed as an interrupt process.
[0070]
  Next, a game control subroutine which is the main control will be described with reference to FIG.
  When this control is started, first, a drive signal output process for outputting a drive signal to a solenoid for driving an electric combination such as the special symbol starting means 20 and the variable winning means 21 is executed (S23). Next, a switch signal input process for reading switch signals from various switches such as a winning detection sensor, a game ball replenishment detection sensor, and a full detection switch provided in each winning means 18 to 21 is executed (S24). Next, the lottery counter is operated to execute a lottery value updating process for generating 300 control random numbers while sequentially updating them within a range of 0 to 299 (S25).
[0071]
  However, in S25, when 300 control random number generations make a round, the top value of the round cycle updated in S15 is extracted, and the top value is updated and set as the initial value in the next round. In this case, the big hit determination symbol such as “17” is also updated at the same time as the initial value of one round cycle is updated. Next, a process of outputting a payout control command to the payout control means 70 is executed (S26), a process of outputting a sound control command to the sound control means 73 is executed (S27), and the lamp control means 71 performs lamp control. Processing for outputting a command is executed (S28).
[0072]
  Next, processing relating to normal symbols is executed (S29), such as normal symbols variably displayed on the symbol display portions 24a and 24b of the normal symbol display means 24. Next, a process related to a special symbol such as displaying the special symbol in a variable manner on the symbol display units 23a to 23c of the special symbol display means 23 is executed (S30). Next, when the opening / closing claw 20a of the special symbol starting means 20 is driven, an operation command output process for outputting a command for instructing the operation is executed (S31). When driving the open / close plate 21a of the variable winning means 21, an operation command output process for outputting a command for instructing the operation is executed (S32), and the process returns.
[0073]
  At the time of this return, when about 2 msec has not elapsed since the start of execution of the main game control subroutine, as described above, the control time is adjusted by repeatedly executing S15 to S16. When a 2 msec interrupt occurs, the main game control subroutine is repeatedly executed. By the way, a power failure occurs in the middle of the game, the main power supply is unexpectedly cut off, AC24V is not supplied to the power supply means 90, and the “L” level voltage abnormality signal VS output from the power supply monitoring means 91 is CPU75, 79. To the highest priority interrupt port.
[0074]
  As a result, the game control is substantially interrupted in the main control means 50, the payout control is substantially interrupted in the payout control means 70, and the backup process is executed by the backup process subroutine. Here, the backup subroutine in the main control means 50 will be described with reference to FIG. When this control is started, the setting information (including various setting values) of registers and stack pointers in the CPU 75 is first stored in the backup information memory 77d (S40).
[0075]
  Next, not only the normal winning means 19 but also the special symbol starting means 20 and the variable winning means 21 are detected but the remaining winning balls remaining without being detected are detected and stored in the backup information memory 77d (S41). Further, the payout means 35 including the ball lending is paid out by the payout means 35 but is detected and stored in the backup information memory 77d (S42). Further, information relating to the player's profit status such as jackpot information relating to the special game, the number of reserved balls of the game ball, and a game ball payout command command are also stored in the backup information memory 77d (S43).
[0076]
  Finally, checksum data is created, the checksum data is stored at the end address of the game control information area 77a (S44), and this interrupt processing control for backup is terminated. Briefly describing the checksum data, each of the storage information stored in the game control information area 77a shown in FIG. 7 has a 2-byte structure, and all of the storage information is converted into binary numbers without carry. The result of addition consisting of 2 bytes (upper 1 byte and lower 1 byte) added by is obtained, and the data of the lower 1 byte is obtained as checksum data.
[0077]
  In this way, after the backup process is executed, the reset signal generating means 92 that has received the voltage abnormality signal VS receives the system reset signal SR (L) for stopping the control operation about 120 msec after receiving the voltage abnormality signal VS. The reset terminals of the CPUs 75, 79, 82 to 84 and the reset terminal of the CPU 75 are simultaneously supplied via the delay circuit 78. Therefore, the CPUs 75, 79, 82 to 84 and RAM of the microcomputers 39A, 40A, 42A, 43A, and 46A are reset, and the control operations of the CPUs 75, 79, and 82 to 84 are completely stopped.
[0078]
  Thereafter, when power is restored from a power failure, the power supply means 90 supplies direct current to each of the microcomputers 39A, 40A, 42A, 43A, 46A, the power supply monitoring means 91 and the reset signal generating means 92. The system reset signal SR (H) is supplied from 92 to the reset terminals of the CPUs 75, 79, 82 to 84, and the game operation control shown in FIG. 14 by the CPU 75 is smaller than the control by the other CPUs 75, 79, 82 to 84. It is delayed by time t. When the game operation control of FIG. 14 is started with a delay of the predetermined minute time t, in this case, the reset switch 86 is not operated (S11: No).
[0079]
  Therefore, when the signal level supplied to the input port of the CPU 75 is read and the power supply abnormality signal Sb of “L” level is inputted from the power supply abnormality detection circuit 95 and is normal (S17: No), the game control information For the storage information stored in the area 77a, as described above, the checksum data of the lower 1 byte of the addition result data consisting of 2 bytes is created by calculation (S20). Next, the checksum data obtained in S20 and the checksum data stored at the end address of the game control information area 77a are compared, and if they match (S21: Yes), backup is performed by the backup information return subroutine. Information restoration processing is executed (S22).
[0080]
  In this backup information restoration processing, the value of the register or stack pointer is set to a predetermined address of the CPU 75 based on the stored information stored in the backup information memory 77d, and a display command for displaying the power failure restoration screen Is transmitted to the symbol control means 60, a display command for displaying the number of reserved balls relating to the normal symbol or the special symbol is transmitted to the lamp control means 71, or a payout command is issued so as to pay out the unpaid game balls. The game control is returned to a state where the game control can be resumed.
[0081]
  Thereafter, as described above, S15 to S16 are repeatedly executed. By the way, if a system reset signal SR is illegally supplied to the main control CPU 75 by a so-called hanging technique or the like by Goto, etc., a control abnormality will occur, and the CPU 75 The value of the program counter is reset. As a result, the game operation control is forcibly reset in the middle of the control, and the game operation control is newly executed from the head step (S11).
[0082]
  If the power supply abnormality signal Sb is normal at the “L” level when the game operation control is started (S17: No), checksum data is created as described above (S20). In this case, the previous backup process(Equivalent to the latest backup process)Since the stored contents of the game control information area 77a at the time and the stored contents at the present time are different, the two checksum data do not match (S21: No), and other than the jackpot related information in the game control information area 77a The game control information is reset (erased) (S13).
[0083]
  As described above, in the state where the main power supply is not cut off, that is, in the state after the power is turned on, when the system reset signal SR is abnormally generated, the game operation control is performed by the system reset signal SR at the first time. Even when the execution is newly started from the step, the jackpot related information such as the jackpot extracting random number and the initial value updating random number is not erased. Therefore, the control random number generated by the random number generating means 51 and each round This initial value can be continued, and it is possible to reliably prevent an illegal big hit lottery hitting by Goto and the like.
[0084]
  By the way, if the backup power supplied from the backup power source 93 to the RAMs 77 and 81 is temporarily interrupted even by Goto, etc., all the memories stored in the RAMs 77 and 81 are stored. The information changes to "00H" data instantly. In addition, in this case, the “H” level power supply abnormality signal Sb is supplied from the output terminal Q of the DF / F 96 in the power supply abnormality detection circuit 95 to the input port of the CPU 75. Therefore, the CPU 75 accesses the RAM 77, and the data read from the game control information area 77a is “00H”, which is impossible. Therefore, an abnormal state error occurs and the system reset signal SR is generated. To do.
[0085]
  As a result, the game operation control is forcibly reset in the middle of the control, and the game operation control is newly executed from the head step (S11). When the game operation control is started, since the power supply abnormality signal Sb of “H” level is input (S17: Yes), an error display associated with the abnormal state is displayed on the symbol control means 60 and the lamp control means 71. Then, an abnormal state notification process (see FIG. 17) is executed (S18).
[0086]
  When this control is started, an error status display command for fraud is first transmitted to the lamp control means 71 (S50). Therefore, the error display lamps provided in the game board 5 and the front frame 4 in the lamp group 72 are displayed blinking at high speed. By blinking the error display lamp, not only the player but also employees of the pachinko hall can be notified that fraud has been performed.
[0087]
  Further, an error status display command due to fraud is transmitted to the symbol control means 60 (S51). Therefore, in the symbol control means 60, even if the special symbol is fluctuating, the display on the symbol display means 22 is switched from the symbol variation to the error display screen, so that it can be notified that fraud has been performed. it can. Further, an error state occurrence command due to fraud is also transmitted to the sound control means 73 (S52). Therefore, in the sound control means 73, since the speaker 74 outputs a sound in which an abnormal situation such as a siren has occurred, it is possible to notify that the fraud has been performed also by the sound.
[0088]
  Next, error information due to fraud is also output to the external output board 32 (S53), the notification process control is terminated, and the process returns to S19 of the game operation control. Therefore, since the error information output to the external output board 32 is transmitted and output to the island computer, it is possible to reliably and accurately manage which pachinko machine 2 is fraudulent on the pachinko hall side. . In this case, in the game operation control of FIG. 14, the hold mode is set by the hold request, and the hold state for the CPU 75 is set (S19).
[0089]
  As a result, the game ball can be launched into the game area 5a via the launch means 10 by operating the launch handle 11, but even if the game ball wins any winning means 18-21, the winning of the game ball is detected. In addition to being unable to do so, game balls will not be paid out for winning. That is, as a result of cheating, not only is the game ball consumed, but a disadvantageous state continues. Of course, in this case as well, it is possible to reliably prevent an illegal hitting lottery by the Goto teacher.
[0090]
  Here, the microcomputer 39A and the backup processing subroutine 76h constitute backup means, and the reset subroutine 76b etc. constitute reset means. The game control information area 77a in the RAM 77 corresponds to information storage means.
[0091]
  Next, a modified embodiment of the embodiment will be described.
  1] The jackpot related information such as the jackpot extraction random number stored in the game control information area 77a may be stored on the tail side of the game control information area 77a. Also in this case, it is possible to continuously store and hold only the jackpot related information at the time of system reset without deleting only the address range for deleting the game control information other than the jackpot related information.
[0092]
  2] In FIG. 14, if the checksum data does not match at the time of a control abnormality, the display lamp by the lamp control means 71 blinks or error information is transmitted to the island computer on the hall side as in S18. You may do it. In this case, the occurrence of an unauthorized system reset can be notified to an illegally playing player or the hall side.
  3] If the reset switch 86 is operated when the power is turned on, the entire game control information area 77a may be erased.
[0093]
  4) The system reset signal SR from the reset signal generating means 92 is configured to be supplied only to the main control board 39 and the payout control board 46, and only the main control means 50 and the payout control means 70 are provided by the system reset signal SR. It may be reset.
  5] The reset signal generating means 92 may be omitted. In this case, the power supply means 45 can be simplified.
[0094]
  6] Any two of the symbol control board 40, the sound control board 43, and the lamp control board 42, for example, the symbol control board 40 and the sound control board 43 may be configured as one printed board, 40 and the lamp control board 42 may be constituted by one printed board, and the sound control board 43 and the lamp control board 42 may be constituted by one printed board. In this case, the freedom degree of arrangement | positioning of these control boards can be raised.
[0095]
  7] The power supply monitoring means 91 may be configured to monitor a DC voltage obtained by rectifying AC24V. In this case, the configuration of the power supply monitoring unit 91 can be simplified.
  8] The present invention is not limited to the embodiments and modifications described above, and various modifications are made without departing from the spirit of the present invention. Furthermore, the present invention is not limited to pachinko machines, but includes game balls, coins, etc. The present invention can be applied to various game machines such as an arrangement ball machine, a sparrow ball game machine, and a revolving game machine using various game media.
[0096]
【The invention's effect】
  Claim 1According to the invention ofGame operation control is started by the game control means, and during the game operation controlWhen a system reset signal is illegally supplied to the main control CPU constituting the main control means by an illegal act such as so-called hanging,Created by checksum processing based on the checksum data created by the checksum processing based on the storage information of the information storage means by the latest backup processing and the storage information of the information storage means when the system reset signal is generated If the checksum data does not match,The value of the program counter is reset,AlsoWhen erasing the stored information in the information storage means, the predetermined game control information of the stored information is left without being deleted, and only the game control information other than the predetermined game control information is deleted. It will be executed from the beginning.
[0097]
  for that reason, Predetermined game control informationIsInitial value update random number for generating big hit random numbersas well asJackpot extraction random numberas well asJackpot symbol determination abuseSince the number is not erased,With regard to the jackpot lottery, these random numbers can be continued instead of being changed to the default values, so that it is possible to surely prevent the illegal hitting lottery from being hit by Goto.
[0098]
  According to the gaming machine of claim 2, when the game operation control is started by the game control means and the reset switch is turned on, the setting information of the arithmetic processing means is initialized, and among the stored information of the information storage means, The game control information other than the predetermined game information is deleted. Therefore, the initial value update random number for generating the jackpot random number, the jackpot extracting random number, and the jackpot symbol determining random number, which are predetermined game control information, are not erased, so even if the game control is resumed after the reset switch is turned on, Regarding the lottery, these random numbers can be continued without changing to the default values.
