Abstract

<P>PROBLEM TO BE SOLVED: To make it difficult to specify the generation timing of a specified numerical value to be the opening condition of a motor-driven accessory from the outside of a game machine. <P>SOLUTION: A new initial value is set as a count value at every cycle (11 counts) of the value of a counter (counter for normal pattern winning judgement) for generating random 5, and the counter steps from the value thereafter. A counter (counter for generating random 7) for determining the initial value of the counter for generating the random 5 is counted up by the remaining time of game control processing. Then, the remaining time is a random period since it is different according to the progress of a game. As a result, since the value of the generated random 7 also becomes a random value, the initial value of the counter for the normal pattern winning judgement changes randomly as well. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a gaming machine such as a pachinko gaming machine that can be changed to an advantageous state for a player when a game is performed using a game medium and a predetermined condition is satisfied.

  As a gaming machine, a game medium such as a game ball is launched into a game area by a launching device, and when a game medium wins a prize area such as a prize opening provided in the game area, a predetermined number of prize balls are paid out to the player. There is something to be done. Further, there is a configuration in which a predetermined game value is given to a player when a predetermined condition is satisfied when a game is being performed. The game value is, for example, the right that the state of the variable winning ball apparatus provided in the gaming area of the gaming machine is advantageous to a player who is easy to win, and the right to be advantageous to the player. In other words, or a condition for winning a prize ball is easily established.

  In pachinko machines, etc., there is a specific gaming state (big hit gaming state) in which a large number of prize balls may be given to the player as an advantageous state for the player. In this case, when a predetermined condition is satisfied, a random number is generated, and when the random number value matches a predetermined jackpot determination value, it is determined to be “big hit”. The random value is generally obtained by extracting the count value of a counter that is periodically counted up and returns to the initial value when the count value exceeds the maximum value.

  Since the count value of the counter is periodically counted up, the timing for generating a random value that matches the jackpot determination value is detected when the count-up cycle or the cycle in which the counter count value makes one round is detected by some means. It will be recognized. Then, it is possible to frequently generate “hit” by playing a game aimed at the timing at which a random number value that matches the jackpot determination value is generated. In some cases, an illegal board is attached to a gaming machine in order to aim at a timing at which a random number value that matches the jackpot value is generated. Such a fraudulent board introduces a signal output to the outside from the circuit part that performs game control, detects the start timing of the circuit part that performs game control based on the signal, and the random value that matches the jackpot determination value is The timing of occurrence is detected. Then, the illegal board can send a predetermined signal to the circuit portion that controls the game at that timing, and illegally generate a “big hit”. As a result, there is a disadvantage in the game store where the gaming machine is installed.

  In order to prevent fraudulent acts due to fraudulent signals aiming at the generation of random numbers that cause “big hits”, when the count value reaches the maximum value, the count value is returned to a random value instead of returning to a specific value. It has been proposed to do so. If such counter control is performed, it is difficult to aim at generation of a random value that causes a “big hit” from the outside.

  As described above, measures are taken to prevent fraudulent acts caused by fraudulent signals aimed at generating random values that cause a specific gaming state. However, in the gaming machine, various random numbers are used in addition to the random number used for determining whether or not to enter a specific gaming state, and if the random number value matches a predetermined value, it will be in an advantageous state for the player. Although gaming machines are configured, sufficient measures are not taken against these random numbers.

  Therefore, the present invention makes it difficult to specify from the outside of the gaming machine the occurrence timing at which the numerical value matches a predetermined value for numerical values other than those used to determine whether or not to enter the specific gaming state. An object of the present invention is to provide a gaming machine that can be used.

  The gaming machine according to the present invention is in a specific gaming state on the condition that the display result on the special variable display section (for example, the variable display device 9) has become a predetermined specific display mode (for example, a combination of symbols generating a big hit). It is a controllable gaming machine, on condition that the display state of the normal variable display unit (for example, the variable display 10) that can change the display state and the display result in the normal variable display unit has become a predetermined display mode. A numerical value for determination used for determining whether or not to display a predetermined display mode in the normal variable winning device (for example, the variable winning ball device 15) that changes to a state advantageous to the player and the normal variable display unit. Determination variable updating means for normal variable display that updates within a predetermined numerical range (for example, a counter for generating random 5), and determination numerical value for normal variable display When the numerical value of the new means is extracted, and the extracted numerical value matches a predetermined determination value, the normal display mode determining means (for example, determining that the display result in the normal variable display unit is set to a predetermined display mode) CPU 56, in particular, the process of step S633), and controls so that the timing at which the numerical value updated by the numerical value updating unit for normal variable display coincides with a predetermined determination value becomes indefinite (for example, steps S124 to S127). ).

  According to a preferred aspect of the present invention, the gaming machine has a normal variable winning device that changes to an advantageous state for the player on the condition that the display result in the normal variable display unit has become a predetermined display mode, and a normal variable display. A numerical value for determination for normal variable display for updating a numerical value for determination used for determining whether or not to display a predetermined display mode in the unit within a predetermined numerical range, and for normal variable display Normal display mode determination for extracting a numerical value of the determination numerical value updating means and determining that the display result in the normal variable display unit is set to a predetermined display mode when the extracted numerical value matches a predetermined determination value And the control is performed so that the timing at which the numerical value updated by the numerical value updating means for normal variable display coincides with the predetermined determination value is normally acceptable. Display result can be difficult to identify from the gaming machine outside the timing determined as a predetermined display mode of the display unit, there is an effect capable of preventing fraud effectively.

Embodiment 1 FIG.
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, the overall configuration of a first type pachinko gaming machine that is an example of a gaming machine will be described. FIG. 1 is a front view of a pachinko gaming machine as viewed from the front, and FIG. 2 is a front view showing the front of the game board.

  The pachinko gaming machine 1 includes an outer frame (not shown) formed in a vertically long rectangular shape and a game frame attached to the inside of the outer frame so as to be openable and closable. Further, the pachinko gaming machine 1 has a glass door frame 2 formed in a frame shape that is provided in the game frame so as to be opened and closed. The game frame includes a front frame (not shown) installed to be openable and closable with respect to the outer frame, a mechanism plate to which mechanism parts and the like are attached, and various parts attached to them (excluding a game board described later). Is a structure including

  As shown in FIG. 1, the pachinko gaming machine 1 has a glass door frame 2 formed in a frame shape. On the lower surface of the glass door frame 2 is a hitting ball supply tray (upper plate) 3. Under the hitting ball supply tray 3, an extra ball receiving tray 4 for storing game balls that cannot be accommodated in the hitting ball supply tray 3 and a hitting operation handle (operation knob) 5 for firing the hitting ball are provided. A game board 6 is detachably attached to the back surface of the glass door frame 2. The game board 6 is a structure including a plate-like body constituting the game board 6 and various components attached to the plate-like body. A game area 7 is formed on the front surface of the game board 6.

  Near the center of the game area 7, a variable display device (special variable display section) 9 including a plurality of variable display sections each variably displaying a symbol as identification information is provided. The variable display device 9 has, for example, three variable display portions (symbol display areas) of “left”, “middle”, and “right”. A start winning opening 14 is provided below the variable display device 9. The winning ball that has entered the start winning opening 14 is guided to the back of the game board 6 and detected by the start opening switch 14a. A variable winning ball device 15 that opens and closes is provided below the start winning opening 14. The variable winning ball device 15 is opened by a solenoid 16.

  An open / close plate 20 that is opened by a solenoid 21 in a specific gaming state (big hit state) is provided below the variable winning ball device 15. The opening / closing plate 20 is a means for opening and closing the special winning opening. Of the winning balls guided from the opening / closing plate 20 to the back of the game board 6, the winning ball entering one (V winning area) is detected by the V winning switch 22, and the winning ball from the opening / closing plate 20 is detected by the count switch 23. Is done. On the back of the game board 6, a solenoid 21A for switching the route in the special winning opening is also provided. Also, at the bottom of the variable display device 9, a special symbol start memory display (hereinafter referred to as a start memory display) 18 using four LEDs for displaying the number of effective winning balls that have entered the start winning opening 14, that is, the start memory number. Is provided. Every time there is a valid start prize, the start memory display 18 increases the number of LEDs to be turned on by one. Each time variable display of the variable display device 9 is started, the number of LEDs to be lit is reduced by one.

  When a game ball wins the gate 32 and is detected by the gate switch 32a, a predetermined random number value is extracted if the normal symbol start memory has not reached the upper limit. And if it is a state which can start the variable display in which a display state changes in the normal symbol display 10, the variable display of the display of the normal symbol display 10 will be started. If the normal symbol display 10 is not ready to start variable display whose display state changes, the value of the normal symbol start memory is incremented by one. In the vicinity of the normal symbol display 10, a normal symbol start memory display 41 having a display unit with four LEDs for displaying the number of normal symbol start memories is provided. Each time there is a prize at the gate 32, the normal symbol start memory display 41 increases the number of LEDs to be turned on by one. Then, every time variable display on the normal symbol display 10 is started, the number of LEDs to be lit is reduced by one. The special symbol and the normal symbol can be variably displayed on one variable display device. In that case, the special variable display unit and the normal variable display unit are realized by one variable display device.

  In this embodiment, the left and right lamps (designs can be visually recognized when lit) are alternately lit to perform variable display, and the variable display continues for a predetermined time (for example, 29 seconds). If the left lamp is turned on at the end of the variable display, it is a win. Whether or not to win is determined by whether or not the value of the random number extracted when the game ball wins the gate 32 matches a predetermined hit determination value. When the display result of the variable display on the normal symbol display 10 is a win, the variable winning ball apparatus 15 is opened for a predetermined number of times for a predetermined time so that the game ball is likely to win. That is, the state of the variable winning ball device 15 changes from a disadvantageous state to a player's advantageous state when the normal symbol is a winning symbol.

  Further, in the probability variation state, the probability that the stop symbol in the normal symbol display 10 becomes a winning symbol is increased, and one or both of the opening time and the number of times of opening of the variable winning ball device 15 are increased. It becomes even more advantageous. Further, in a predetermined state such as a probability change state, the variable display period (fluctuation time) in the normal symbol display 10 may be shortened, which may be more advantageous for the player.

  The gaming board 6 is provided with a plurality of winning holes 29, 30, 33, 39, and winning of the game balls to the winning holes 29, 30, 33 is detected by winning hole switches 29a, 30a, 33a, 39a, respectively. The Decorative lamps 25 blinking during the game are provided around the left and right sides of the game area 7, and an outlet 26 for absorbing a hit ball that has not won a prize is provided below. Two speakers 27 that emit sound effects are provided on the left and right upper portions outside the game area 7. On the outer periphery of the game area 7, a top frame lamp 28a, a left frame lamp 28b, and a right frame lamp 28c are provided. Further, a decoration LED is installed around each structure (such as a big prize opening) in the game area 7. The top frame lamp 28a, the left frame lamp 28b, the right frame lamp 28c, and the decoration LED are examples of a decorative light emitter provided in the gaming machine.

  In this example, a prize ball lamp 51 that is turned on when there is a remaining number of prize balls is provided in the vicinity of the left frame lamp 28b, and a ball that is turned on in the vicinity of the top frame lamp 28a when the supply ball is cut. A cut lamp 52 is provided. Further, FIG. 1 also shows a card unit 50 that is installed adjacent to the pachinko gaming machine 1 and enables lending of a ball by inserting a prepaid card.

  The card unit 50 has a usable indicator lamp 151 indicating whether or not it is in a usable state, and when the remaining amount information recorded in the card has a fraction (a number less than 100 yen), the fraction is indicated as a hitting tray. 3, a fraction display switch 152 for displaying on a frequency display LED provided in the vicinity of 3, a connecting table direction indicator 153 indicating which side of the pachinko gaming machine 1 corresponds to the card unit 50, in the card unit 50 Check the card insertion indicator lamp 154 indicating that a card is inserted, the card insertion slot 155 into which a card as a recording medium is inserted, and the mechanism of the card reader / writer provided on the back of the card insertion slot 155. In some cases, a card unit lock 156 is provided for releasing the card unit 50.

  The game balls launched from the hit ball launching device enter the game area 7 through the hit ball rail, and then descend the game area 7. When the hit ball enters the start winning opening 14 and is detected by the start opening switch 14a, the variable display device 9 starts variable display (variation) if the variable display of the symbol can be started. If the variable display of the symbol cannot be started, the start memory number is increased by one.

  The variable display of the special symbol on the variable display device 9 stops when a certain time has elapsed. If the combination of the special symbols at the time of the stop is a jackpot symbol (specific display mode), the game shifts to a jackpot gaming state. That is, the opening / closing plate 20 is opened until a predetermined time elapses or a predetermined number (for example, 10) of hit balls wins. When the hit ball enters the V winning area while the opening / closing plate 20 is opened and is detected by the V winning switch 22, a continuation right is generated and the opening / closing plate 20 is opened again. The generation of the continuation right is allowed a predetermined number of times (for example, 15 rounds).

  When the combination of special symbols in the variable display device 9 at the time of stopping is a combination of jackpot symbols (probability variation symbols) with probability fluctuations, the probability of the next jackpot increases. That is, it becomes a more advantageous state for the player in the probability variation state.

  Next, the structure of the back surface of the pachinko gaming machine 1 will be described with reference to FIG. FIG. 3 is a rear view of the gaming machine as seen from the back side.

  As shown in FIG. 3, on the back side of the gaming machine, a game control board (main board) 31 on which a variable display control unit 49 including a symbol control board 80 for controlling the variable display device 9, a game control microcomputer, and the like are mounted.

Is provided. In addition, a power supply board 910 and a launch control board 91 on which a power supply circuit for generating DC30V, DC21V, DC12V, and DC5V is mounted are provided.

  On the back side of the gaming machine, a terminal board 160 provided with terminals for outputting various information to the outside of the gaming machine is installed above. The terminal board 160 has at least a ball break terminal for introducing and outputting an output of the ball break detection switch, an award ball terminal for outputting the award ball number signal to the outside, and a ball lending number signal externally output. A ball lending terminal is provided. In addition, an information terminal board 34 having terminals for outputting various information from the main board 31 to the outside of the gaming machine is installed near the center.

  Further, backup data stored in storage content holding means (for example, variable data storage means that can hold the contents even when power supply is stopped, that is, a backup RAM) included in each board (main board 31 and payout control board 37). There is provided a switch board 190 on which a clear switch 921 is mounted as an operation means for clearing. The switch board 190 is provided with a clear switch 921 and a connector 922 connected to another board such as the main board 31.

  The game balls stored in the storage tank 38 pass through the guide rail and reach the ball payout device covered with the prize ball case 40A. A ball break switch 187 as a game medium break detection means is provided on the upper part of the ball payout device. When the ball break switch 187 detects a ball break, the dispensing operation of the ball dispensing device stops. The ball break switch 187 is a switch for detecting the presence or absence of a game ball in the game ball passage, but the ball break detection switch 167 for detecting the shortage of supply balls in the storage tank 38 is also an upstream portion (in the storage tank 38) of the guide rail. (Proximate part). When the ball break detection switch 167 detects the shortage of game balls, the game machine is replenished to the game machine from the supply mechanism provided on the gaming machine installation island.

  A large number of game balls as prizes based on winning prizes and game balls based on ball lending requests are paid out to fill the hitting ball supply tray 3, and when the game balls are further paid out, the game balls are guided to the surplus ball receiving tray 4. When the game ball is further paid out, a full switch 48 (not shown in FIG. 3) is turned on. In this state, the rotation of the payout motor in the ball payout device stops, the operation of the ball payout device stops, and the drive of the launching device also stops.

  FIG. 4 is a block diagram illustrating an example of a circuit configuration in the main board 31. 4 also shows a payout control board 37, a lamp control board 35, a sound control board 70, a launch control board 91, and a symbol control board 80. The main board 31 includes a basic circuit 53 for controlling the pachinko gaming machine 1 according to a program, a gate switch 32a, a start port switch 14a, a V winning switch 22, a count switch 23, winning port switches 29a, 30a, 33a, 39a, A switch circuit 58 for supplying signals from the tongue switch 48, the ball break switch 187, the prize ball count switch 301A and the clear switch 921 to the basic circuit 53, a solenoid 16 for opening and closing the variable winning ball apparatus 15, and a solenoid for opening and closing the opening and closing plate 20. 21 and a solenoid circuit 59 for driving a solenoid 21A for switching a route in the special winning opening in accordance with a command from the basic circuit 53 is mounted.

  Although not shown in FIG. 4, the count switch short circuit signal is also transmitted to the basic circuit 53 via the switch circuit 58. Further, the gate switch 32a, the start port switch 14a, the V winning switch 22, the count switch 23, the winning port switches 29a, 30a, 33a, 39a, the full switch 48, the ball running switch 187, the winning ball count switch 301A, etc. Also, what is called a sensor may be used. That is, the name of the game medium detection means (game ball detection means in this example) that can detect a game ball is not limited. What is called a switch may be what is called a sensor, that is, that the switch is an example of a game medium detecting unit, as in other embodiments.

  Further, according to the data given from the basic circuit 53, the jackpot information indicating the occurrence of the jackpot, the effective starting information indicating the number of starting winning balls used for starting the variable display of the symbols in the variable display device 9, the probability variation has occurred. An information output circuit 64 for outputting an information output signal such as probability variation information indicating the above to an external device such as a hall computer is mounted.

  The basic circuit 53 includes a ROM 54 for storing a game control program and the like, a RAM 55 as storage means (means for storing variation data) used as a work memory, a CPU 56 for performing control operations according to the program, and an I / O port unit 57. including. In this embodiment, the ROM 54 and RAM 55 are built in the CPU 56. That is, the CPU 56 is a one-chip microcomputer. The one-chip microcomputer only needs to incorporate at least the RAM 55, and the ROM 54 and the I / O port unit 57 may be externally attached or built-in.

  Further, a part or all of the RAM (may be a CPU built-in RAM) 55 is a backup RAM that is backed up by a backup power source created in the power supply substrate 910. That is, even if the power supply to the gaming machine is stopped, a part or all of the contents of the RAM 55 is saved for a predetermined period.

  A ball hitting device for hitting and launching a game ball is driven by a drive motor 94 controlled by a circuit on the launch control board 91. Then, the driving force of the drive motor 94 is adjusted according to the operation amount of the operation knob 5. That is, the circuit on the firing control board 91 is controlled so that the hit ball is fired at a speed corresponding to the operation amount of the operation knob 5.

  In this embodiment, the lamp control means mounted on the lamp control board 35 performs display control of the start memory display 18, the normal symbol start memory display 41 and the decoration lamp 25 provided on the game board. The display control of the top frame lamp 28a, the left frame lamp 28b, the right frame lamp 28c, the prize ball lamp 51 and the ball-out lamp 52 provided on the frame side is performed. Each lamp may be an LED or other types of light emitters, and the LEDs used in this embodiment and other embodiments may be other types of light emitters. That is, a lamp or LED is an example of a light emitter. In addition, display control of the variable display device 9 for variably displaying the special symbol and the normal symbol display 10 for variably displaying the normal symbol is performed by display control means mounted on the symbol control board 80.

  FIG. 5 shows the circuit configuration in the symbol control board 80, LCD (liquid crystal display device) 82, which is one example of realization of the variable display device 9, the normal symbol display 10, and the output ports (ports 0 and 2) of the main board 31. It is a block diagram shown with 570,572 and output buffer circuit 620,62A. The output port (output port 2) 572 outputs 8-bit data, and the output port 570 outputs a 1-bit strobe signal (INT signal).

  The display control CPU 101 operates in accordance with a program stored in the control data ROM 102. When an INT signal is input from the main board 31 via the noise filter 107 and the input buffer circuit 105B, display control is performed via the input buffer circuit 105A. Receive commands. As the input buffer circuits 105A and 105B, for example, general-purpose ICs 74HC540 and 74HC14 can be used. When the display control CPU 101 does not have an I / O port, an I / O port is provided between the input buffer circuits 105A and 105B and the display control CPU 101.

  Then, the display control CPU 101 performs display control of the screen displayed on the LCD 82 in accordance with the received display control command. Specifically, a command corresponding to the display control command is given to the VDP 103. The VDP 103 reads out necessary data from the character ROM 86. The VDP 103 generates image data to be displayed on the LCD 82 according to the input data, and outputs R, G, B signals and a synchronization signal to the LCD 82.

  5 also shows a reset circuit 83 for resetting the VDP 103, an oscillation circuit 85 for supplying an operation clock to the VDP 103, and a character ROM 86 for storing frequently used image data. The frequently used image data stored in the character ROM 86 is, for example, a person, animal, or an image made up of characters, figures, symbols, or the like displayed on the LCD 82.

  The input buffer circuits 105A and 105B can pass signals only in the direction from the main board 31 toward the symbol control board 80. Therefore, there is no room for signals to be transmitted from the symbol control board 80 side to the main board 31 side. That is, the input buffer circuits 105A and 105B constitute irreversible information input means together with the input ports. Even if the tampering is added to the circuit in the symbol control board 80, the signal output by the tampering is not transmitted to the main board 31 side.

  For example, a three-terminal capacitor or a ferrite bead is used as the noise filter 107 that cuts off the high-frequency signal. However, even if noise is added between the substrates due to the presence of the noise filter 107, the influence is eliminated. . A noise filter may also be provided on the output side of the buffer circuits 620 and 62A of the main board 31.

  FIG. 6 is a block diagram illustrating a configuration example of the power supply substrate 910. The power supply board 910 is installed independently of the electric part control boards such as the main board 31, the symbol control board 80, the sound control board 70, the lamp control board 35, and the payout control board 37, and each electric part control board in the gaming machine and Generates voltage used by mechanical components. In this example, AC24V, VSL (DC + 30V), DC + 21V, DC + 12V, and DC + 5V are generated. Further, a capacitor 916 serving as a backup power source, that is, a memory holding means, is charged from a line of power source for driving DC + 5V, that is, an IC or the like on each substrate. Note that VSL is generated by rectifying and boosting AC24V with a rectifier element in the rectifier circuit 912. VSL is a solenoid driving power source.

  The transformer 911 converts AC voltage from the AC power source into 24V. The AC 24V voltage is output to the connector 915. The rectifier circuit 912 also generates a DC voltage of +30 V from AC 24 V and outputs it to the DC-DC converter 913 and the connector 915. The DC-DC converter 913 has one or a plurality of converter ICs 922 (only one is shown in FIG. 6), generates + 21V, + 12V, and + 5V based on VSL and outputs them to the connector 915. A relatively large capacitor 923 is connected to the input side of the converter IC 922. Accordingly, when the power supply to the gaming machine from the outside is stopped, the DC voltage such as + 30V, + 12V, + 5V, etc., decreases relatively slowly. The connector 915 is connected to, for example, a relay board, and power of a voltage necessary for each electric component control board and the mechanism component is supplied from the relay board.

  However, each connector reaching each electric component control board may be provided on the power supply board 910 to supply each voltage from the power supply board 910 to each board without going through the relay board. FIG. 6 shows one connector 915 as a representative, but the connector is provided for each electric component control board.

  The + 5V line from the DC-DC converter 913 branches to form a backup + 5V line. A large-capacitance capacitor 916 is connected between the backup + 5V line and the ground level. The capacitor 916 has a storage state with respect to the backup RAM of the electrical component control board when the power supply to the gaming machine is stopped (a RAM that is backed up by power, that is, a backup storage unit that can be in a storage content holding state even when the power supply is stopped). It becomes a backup power supply that supplies power so that it can be maintained. Further, a backflow preventing diode 917 is inserted between the + 5V line and the backup + 5V line. In this embodiment, +5 V for backup is supplied to the main board 31 and the payout control board 37.

  The power supply board 910 is equipped with a power supply monitoring IC 902 as a power supply monitoring circuit. The power monitoring IC 902 detects the occurrence of power supply stoppage to the gaming machine by introducing the VSL voltage and monitoring the VSL voltage. Specifically, when the VSL voltage becomes equal to or lower than a predetermined value (+22 V in this example), a power-off signal is output because power supply is stopped. The power supply voltage to be monitored is preferably higher than the power supply voltage (+5 V in this example) of the circuit element mounted on each electric component control board. In this example, VSL, which is a voltage immediately after being converted from AC to DC, is used. A power-off signal from the power monitoring IC 902 is supplied to the main board 31, the payout control board 37, and the like.

  The predetermined value for the power monitoring IC 902 to detect the stop of power supply is lower than the normal voltage, but is a voltage that allows the CPU on each electrical component control board to operate for a while. Further, the power monitoring IC 902 is configured to monitor a voltage that is higher than a voltage for driving a circuit element such as a CPU (+5 V in this example) and immediately after being converted from AC to DC. Therefore, the monitoring range can be expanded for the voltage required by the CPU. Therefore, more precise monitoring can be performed. Furthermore, when VSL (+ 30V) is used as the monitoring voltage, the voltage supplied to the various switches of the gaming machine is + 12V, so that it can be expected to prevent erroneous switch-on detection at the time of instantaneous power interruption. That is, when the voltage of the + 30V power supply is monitored, it is possible to detect a decrease in the level before + 12V created after the creation of + 30V starts to drop.

  When the voltage of the + 12V power supply decreases, the switch output becomes on. However, if the power supply voltage is monitored by monitoring the + 30V power supply voltage, which decreases faster than + 12V, and the power supply is stopped, the switch output is turned on. It is possible to enter a supply recovery waiting state and not detect the switch output.

  Further, since the power monitoring IC 902 is mounted on the power supply board 910 that is separate from the electrical component control board, a power-off signal can be supplied from the power monitoring circuit to the plurality of electrical component control boards. Even if there are any number of electrical component control boards that require a power-off signal, it is only necessary to provide one power supply monitoring means. Therefore, even if each electrical component control means in each electrical component control board performs recovery control described later. The cost of the gaming machine does not increase so much.

  In the configuration shown in FIG. 6, the detection signal (power cut-off signal) of the power monitoring IC 902 is supplied to the respective electric component control boards (for example, the main board 31 and the payout control board 37) via the buffer circuits 918 and 919. For example, a configuration may be adopted in which one detection signal is transmitted to the relay board, and the same signal is distributed from the relay board to each electrical component control board. Further, a buffer circuit corresponding to the number of substrates that require a power-off signal may be provided. Further, regarding the power-off signal output to the main board 31 and the payout control board 37, the monitoring voltage of the power supply monitoring circuit that outputs the power-off signal may be different.

  The power-off signal from the power supply monitoring circuit (power supply monitoring means) on the power supply board 910 is connected to the non-maskable interrupt terminal (XNMI terminal) of the CPU 56 on the main board 31. Therefore, the CPU 56 can confirm the occurrence of the stop of power supply to the gaming machine by the non-maskable interrupt (NMI) process.

  While power is not supplied from the + 5V power source that is the driving power source of the CPU 56 or the like, at least a part of the RAM is backed up by the backup power source supplied from the power supply board, and the contents are preserved even if the power supply to the gaming machine is stopped. Is done. When the + 5V power supply is restored, a reset signal is issued from the system reset circuit 65, and the CPU 56 returns to a normal operation state. At that time, since necessary data is stored in the backup RAM, it is possible to restore the gaming state at the time of occurrence of a power failure or the like at the time of recovery from the power failure or the like.

  Next, the operation of the gaming machine will be described. FIG. 7 is a flowchart showing main processing executed by game control means (CPU 56 and peripheral circuits such as ROM and RAM) on the main board 31. When power is turned on to the gaming machine and the input level of the reset terminal becomes high level, the CPU 56 starts main processing after step S1. In the main process, the CPU 56 first performs necessary initial settings.

  In the initial setting process, the CPU 56 first sets the interrupt prohibition (step S1). Next, the interrupt mode is set to interrupt mode 2 (step S2), and a stack pointer designation address is set to the stack pointer (step S3). Then, the built-in device register is initialized (step S4). Further, after initialization (step S5) of CTC (counter / timer) and PIO (parallel input / output port) which are built-in devices (built-in peripheral circuits), the RAM is set to an accessible state (step S6).

  The CPU 56 used in this embodiment also incorporates an I / O port (PIO) and a timer / counter circuit (CTC).

  In the CPU 56 used in this embodiment, three types of modes are prepared as maskable interrupt modes. When a maskable interrupt occurs, the CPU 56 automatically sets the interrupt disabled state and saves the contents of the program counter in the stack.

  Of the three types of interrupt mode 2, the address synthesized from the value (1 byte) of the specific register (I register) of the CPU 56 and the interrupt vector (1 byte: least significant bit 0) output from the built-in device is This mode indicates an interrupt address. That is, the interrupt address is an address indicated by 2 bytes in which the upper address is the value of the specific register and the lower address is the interrupt vector. Therefore, an interrupt process can be set at an arbitrary address (although it is skipped). Each built-in device has a function of sending an interrupt vector when making an interrupt request. In step S2 of the initial setting process, the CPU 56 is set to the interrupt mode 2.

  Next, the CPU 56 confirms the state of the output signal of the clear switch 921 input via the input port 1 only once (step S7). When the on-state is detected in the confirmation, the CPU 56 executes normal initialization processing (steps S11 to S15). When the clear switch 921 is on (when pressed), a low-level clear switch signal is output.

  If the clear switch 921 is not in the on state, whether or not data protection processing of the backup RAM area (for example, power supply stop processing such as addition of parity data) has been performed when power supply to the gaming machine is stopped Confirm (step S8). In this embodiment, when power supply is stopped, a process for protecting data in the backup RAM area is performed. When such protection processing is performed, it is assumed that there is a backup. When it is confirmed that such protection processing is not performed, the CPU 56 executes initialization processing.

  In this embodiment, whether or not there is backup data in the backup RAM area is confirmed by the state of the backup flag set in the backup RAM area in the power supply stop process. In this example, for example, if “55H” is set in the backup flag area, it means that there is a backup (ON state), and if a value other than “55H” is set, it means that there is no backup (OFF state). .

  After confirming that there is a backup, the CPU 56 performs a data check of the backup RAM area (parity check in this example) (step S9). In the power supply stop process executed when power supply to the gaming machine is stopped, a checksum is calculated, and the checksum is stored in the backup RAM area. In step S9, the calculated checksum is compared with the stored checksum. When the power supply is stopped after an unexpected power failure or the like, the data in the backup RAM area should be saved, so the check result (comparison result) is normal (matched). That the check result is not normal means that the data in the backup RAM area is different from the data when the power supply is stopped. In such a case, since the internal state cannot be returned to the state when the power supply is stopped, an initialization process that is executed when the power is turned on is not performed when the power supply is stopped.

  If the check result is normal, the CPU 56 performs a game state restoration process for returning the internal state of the game control means and the control state of the electric component control means such as the display control means to the state when the power supply is stopped (step S10). ). Then, the saved value of the PC (program counter) saved in the backup RAM area is set in the PC, and the address is restored. In the game state restoration process, the PC is restored to the state before the power supply was stopped, and various data (for example, a counter for generating each random number) is stored in the backup RAM. If the power supply is restored within a predetermined time (a period in which data can be stored in the backup RAM) after the operation stops, for example, the count value of a counter for generating a determination random number, a display random number, and an initial value random number described later is The operation is continued from the state before the power supply is stopped.

  In the initialization process, the CPU 56 first performs a RAM clear process (step S11). In addition, a predetermined work area (for example, a normal symbol determination random number counter, a normal symbol determination buffer, a special symbol left middle right symbol buffer, a special symbol process flag, a payout command storage pointer, a winning ball flag, a ball out flag, a payout A work area setting process for setting an initial value to a flag such as a stop flag for selectively performing processing according to the control state is performed (step S12). Further, a process of transmitting a payout permission state designation command for instructing that payout from the ball payout device 97 is possible to the payout control board 37 is performed (step S13). Further, a process of transmitting an initialization command for initializing other sub boards (lamp control board 35, sound control board 70, symbol control board 80) to each sub board is executed (step S14). As an initialization command, a command indicating the initial symbol displayed on the variable display device 9 (for the symbol control board 80) and a command for instructing the extinction of the prize ball lamp 51 and the ball-out lamp 52 (to the lamp control board 35) Etc).

  Then, a CTC register set in the CPU 56 is set so that a timer interrupt is periodically generated every 2 ms (step S15). That is, a value corresponding to 2 ms is set in a predetermined register (time constant register) as an initial value.

  When the execution of the initialization process (steps S11 to S15) is completed, the display random number update process (step S17) and the initial value random number update process (step S18) are repeatedly executed in the main process. When the display random number update process and the initial value random number update process are executed, the interrupt disabled state is set (step S16). When the display random number update process and the initial value random number update process are finished, the interrupt enabled state is set. (Step S19). When the display random number update process and the initial value random number update process are executed, the interrupt is prohibited. Therefore, a 2 ms timer interrupt described later is generated while the random number update process is being executed. A random number update process is executed in the process, and a contradiction in the count value is prevented.

  The display random number is a random number for determining a symbol displayed on the variable display device 9, and the display random number update process is a process for updating the count value of the counter for generating the display random number. is there. The initial value random number update process is a process for updating the count value of the counter for generating the initial value random number. The initial value random number is the initial value of the count value (a value exceeding the maximum value is returned) such as a counter for generating a random number for determining whether or not to make a big hit (a random number generation counter for big hit determination). Is a random number for determining the value.

  When the timer interrupt occurs, the CPU 56 performs the register saving process (step S20), and then executes the game control processes of steps S21 to S32 shown in FIG. In the game control process, the CPU 56 first inputs detection signals of switches such as the gate switch 32a, the start port switch 14a, the count switch 23, and the winning port switches 29a, 30a, 33a, and 39a through the switch circuit 58. These state determinations are performed (switch processing: step S21).

  Next, various abnormality diagnosis processes are performed by the self-diagnosis function provided in the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error process: step S22).

  Next, a process of updating the count value of each counter for generating each determination random number such as a big hit determination random number used for game control is performed (step S23). The CPU 56 further performs a process of updating the count value of the counter for generating the display random number and the initial value random number (steps S24 and S25).

  Further, the CPU 56 performs special symbol process processing (step S26). In the special symbol process control, corresponding processing is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to the gaming state. The value of the special symbol process flag is updated during each process according to the gaming state. Further, normal symbol process processing is performed (step S27). In the normal symbol process, the corresponding process is selected and executed according to the normal symbol process flag for controlling the display state of the normal symbol display 10 in a predetermined order. The value of the normal symbol process flag is updated during each process according to the gaming state.

  Next, the CPU 56 performs processing for setting a display control command related to the special symbol in a predetermined area of the RAM 55 and transmitting the display control command (special symbol command control processing: step S28). Further, a process for transmitting a display control command by setting a display control command related to the normal symbol in a predetermined area of the RAM 55 is performed (normal symbol command control process: step S29).

  Further, the CPU 56 performs information output processing for outputting data such as jackpot information, start information, probability variation information supplied to the hall computer, for example (step S30).

  Further, the CPU 56 issues a drive command to the solenoid circuit 59 when a predetermined condition is satisfied (step S31). The solenoid circuit 59 drives the solenoids 16, 21, and 21A in response to a drive command in order to open or close the variable winning ball device 15 or the opening / closing plate 20, or to switch the game ball passage in the special winning opening. To do.

  Then, the CPU 56 executes a prize ball process for setting the number of prize balls based on the detection signals from the winning opening switches 29a, 30a, 33a, 39a (step S32). Specifically, a payout control command indicating the number of winning balls is output to the payout control board 37 in response to winning detection based on the winning opening switches 29a, 30a, 33a, 39a being turned on. The payout control CPU 371 mounted on the payout control board 37 drives the ball payout device 97 according to a payout control command indicating the number of prize balls. Thereafter, the contents of the register are restored (step S33), and the interrupt permission state is set (step S34).

  With the above control, in this embodiment, the game control process is started every 2 ms. In this embodiment, the game control process is executed by the timer interrupt process. However, in the timer interrupt process, for example, only a flag indicating that an interrupt has occurred is set, and the game control process is performed by the main process. May be executed.

  FIG. 9 is a flowchart showing an example of a special symbol process processing program executed by the CPU 56. The special symbol process shown in FIG. 9 is a specific process of step S26 in the flowchart of FIG. When performing the special symbol process, the CPU 56 performs the fluctuation shortening timer subtraction process (step S310) and the start port switch passage confirmation process (step S311), and then according to the internal state (in this example, the special symbol process flag). Then, any one of steps S300 to S309 is performed.

  The variation shortening timer subtraction process is a process of subtracting the number of variation shortening timers corresponding to the maximum number that can be stored in the start memory (the memory that the start port switch 14a is turned on). In a special symbol jackpot determination process (step S301), which will be described later, for example, when the value of the fluctuation shortening timer is 0 and the low probability state (normal state), the starting memory number is the maximum value of the starting memory, and the probability variation. In the state, if the number of starting memories is “2” or more, it is determined to use a pattern with a shortened variation time as a symbol variation pattern. The start port switch passage confirmation process is a process for acquiring and storing predetermined random numbers when the start port switch 14a is turned on.

  In steps S300 to S309, the following processing is performed.

  Special symbol normal processing (step S300): The starting memory number is confirmed. If the starting memory number is not 0, the value of the special symbol process flag is changed so as to proceed to step S301.

  Special symbol jackpot determination process (step S301): The contents of a buffer or the like for storing various random numbers stored when a start win is received are shifted. As a result of the shift, it is determined whether or not to make a big hit based on the contents of the pushed-out buffer. Note that the maximum number of buffers that can be stored for start winnings is prepared. Further, the content of the buffer pushed out by the shift is the content corresponding to the start winning that occurred most recently. If it is decided to win, the big hit flag is set. Thereafter, the value of the special symbol process flag is changed so as to proceed to step S302.

  Stop symbol setting process (step S302): The stop symbol of the left / right middle symbol which is the display result on the variable display device 9 is determined. Then, the value of the special symbol process flag is changed so as to proceed to step S303.

  Fluctuation pattern setting process (step S303): A pattern variation display pattern on the variable display device 9, that is, a variation pattern (variable display pattern) is determined. Then, a control command for notifying the determined variation pattern, stop symbol and the like is output to the symbol control board 80 and the like. Thereafter, the value of the special symbol process flag is changed so as to proceed to step S304.

  Special symbol variation processing (step S304): It is confirmed whether or not the variation time determined according to the variation pattern has elapsed. If it has elapsed, the value of the special symbol process flag is changed so as to proceed to step S305.

  Special symbol stop process (step S305): When a predetermined time (for example, 1.000 seconds) has passed and it has been decided to win, the value of the special symbol process flag is shifted to step S306. To change. Otherwise, the value of the special symbol process flag is changed so as to proceed to step S300.

  Preliminary winning opening opening process (step S306): Control for opening the large winning opening is started. Specifically, the counter and flag are initialized, and the solenoid 54 is driven to open the special winning opening. Then, the value of the special symbol process flag is changed so as to proceed to step S307.

  Processing for opening a special winning opening (step S307): A process for confirming the closing condition of the special winning opening is performed. If the closing condition for the big prize opening is satisfied, the value of the special symbol process flag is changed so as to proceed to step S308.

  Specific area valid time process (step S308): The presence / absence of passing of the V winning switch 22 is monitored, and the process of confirming that the big hit gaming state continuation condition is satisfied is performed. If the condition for continuation of the big hit gaming state is satisfied and there are still remaining rounds, the value of the special symbol process flag is changed so as to proceed to step S307. Further, when the big hit gaming state continuation condition is not satisfied within the predetermined effective time, or when all rounds are finished, the value of the special symbol process flag is changed so as to proceed to step S309.

  Big hit end processing (step S309): Control is performed to cause the lamp control means or the like to display to notify the player that the big hit gaming state has ended. Then, the value of the special symbol process flag is changed so as to proceed to step S300.

  FIG. 10 is a flowchart showing the start port switch passage confirmation process (step S311). When the hit ball wins the start winning opening 14 provided in the game board, the start opening switch 14a is turned on. When determining that the start port switch 14a is turned on via the switch circuit 58 (step S41), the CPU 56 checks whether or not the start memory number has reached the upper limit value (4 in this example) (step S42). If the starting memory number has not reached the upper limit value, the starting memory number is increased by 1 (step S43), and the value of each random number such as a big hit determination random number is extracted. Then, they are stored in a random value storage area corresponding to the value of the starting memory number (step S44). When the starting memory number has reached the upper limit value, the process for increasing the starting memory number is not performed.

  When the start memory number is increased by 1, a lamp control command for increasing the display number of the start memory display 18 (the number of lit LEDs) by 1 is transmitted to the lamp control board 35.

  In the special symbol process of step S25, the CPU 56 checks the value of the start memory number as shown in FIG. 11 (step S51). If the starting memory number is not 0, the value stored in the random number storage area corresponding to the starting memory; 1 (first starting memory) is read (step S52), and the value of the starting memory number is decreased by 1, And the value of each random value storage area is shifted (step S53). That is, each value stored in the random number value storage area corresponding to the start memory; n (n = 2,..., 4) is stored in the random number value storage area corresponding to the start memory: n−1. Note that the contents of the random number storage area corresponding to the start memory number at that time are cleared. For example, when the start memory number is 4, the contents of the special symbol random number storage area corresponding to the start memory; 4 are cleared.

  When the start memory number is decreased by 1, a lamp control command for reducing the display number of the start memory display 18 by 1 is transmitted to the lamp control board 35.

  Then, the CPU 56 determines the winning / losing based on the value read in step S52, that is, the value of the extracted jackpot determination random number (special symbol determination random number) (step S54). Here, the jackpot determination random number takes a value in the range of 0 to 316. Then, as shown in FIG. 12, in the normal state, for example, when the value is “3”, it is determined as “big hit”, and when it is other than that, it is determined as “loss”. Further, in the high probability state (probability variation state), for example, when the value is any of “3”, “7”, “79”, “103”, “107”, it is determined as “big hit”, otherwise If it is the value of, it is determined as “out of”.

FIG. 13 is an explanatory diagram showing each random number. Each random number is used as follows.
(1) Random 1: Decide whether or not to generate a big hit (for big hit judgment)
(2) Random 2-1-2-3: For left and right middle detachment symbol determination (special symbol left and right middle)
(3) Random 3: Determines the combination of special symbols that generate a big hit (for determining big hit symbols)
(4) Random 4: Determines the variation pattern of the special symbol in the variable display device 9 (for variation pattern determination)
(5) Random 5: Decide whether or not to generate a hit based on the normal symbol in the normal symbol display 10 (for normal symbol per unit determination)
(6) Random 6: Determine the initial value of random 1 (for determining the random 1 initial value)
(7) Random 7: Determine the initial value of random 5 (for determining the random 5 initial value)

  In step S23 in the game control process shown in FIG. 8, the CPU 56 obtains (1) big hit determination random number, (3) big hit symbol determination random number, and (5) normal symbol random number for determination. The counter for generating is incremented (added by 1). That is, they are determination random numbers, and other random numbers are display random numbers or initial value random numbers. In order to enhance the game effect, random numbers related to ordinary symbols other than the random numbers (1) to (7) are also used.

  In step S54 shown in FIG. 11, when it is determined that the jackpot is a jackpot symbol is determined according to the value of the jackpot symbol random number (random 3) (step S55). In this embodiment, each symbol of the symbol number set in the jackpot symbol table corresponding to the value of random 3 is determined as a jackpot symbol. In the jackpot symbol table, left and right symbol numbers corresponding to combinations of a plurality of types of jackpot symbols are set. Further, a random number for determining a variation pattern (random 4) is extracted, and a variation pattern of the symbol is determined based on the random 4 value (step S56).

  When it is determined that there is a loss, the CPU 56 determines a stop symbol when it is not a big hit. In this embodiment, the left symbol is determined according to the value read in step S52, that is, the extracted random 2-1 value (step S57). Further, the medium symbol is determined according to the value of random 2-2 (step S58). Then, the right symbol is determined according to the random 2-3 value (step S59). Here, if the determined middle symbol matches the left and right symbols, the symbol corresponding to the value obtained by adding 1 to the random number corresponding to the middle symbol is set as the stop symbol of the middle symbol so that it does not match the jackpot symbol. To do.

  Further, the CPU 56 confirms whether or not it has been decided to reach (whether or not the left and right stop symbols are aligned) (step S60). A random number (random 4) value is extracted, and a symbol variation pattern is determined based on random 4 (step S61).

  If it is not decided to reach, it is confirmed whether or not it is in the probability variation state (step S62). If it is in the probability variation state, the variation pattern is determined to be the off-time variation variation pattern (step S63). If it is not the probability variation state, it is determined that the variation pattern is the normal variation pattern at the time of deviation (step S64). In addition, the fluctuation pattern shortened at the time of detachment is a fluctuation pattern in which the fluctuation period is shorter than the normal fluctuation pattern in which the fluctuation time of the left and right symbols is 4.0 seconds, for example.

  As described above, it is determined whether the pattern variation mode based on the start winning is the reach mode or the off mode, and the combination of the respective stop symbols is determined. That is, as a symbol variation mode, whether or not a reach effect is performed is determined and a combination of stop symbols is determined.

  The process shown in FIG. 11 corresponds to the process in the case where the processes of steps S301 to S303 in the special symbol process shown in FIG. 9 are collectively shown. In this embodiment, a big hit occurs when the left and right middle symbols are aligned. Reach when only left and right symbols are available.

  14 and 15 are flowcharts showing an example of the determination random number update process (step S23) executed in the game control process shown in FIG. In the determination random number update process, the CPU 56 increments the value of the counter (random 1 counter) for generating random 1 (big hit determination random number) by 1 (step S101). When the value of the counter for generating random 1 is equal to or greater than (maximum value + 1) (step S102), the value is returned to 0 (step S103). In this embodiment, (maximum value + 1) is 317. A value read from a counter (random 1 counter) for generating random 1 at a predetermined timing is the extracted random 1 (big hit determination random number). Similarly, the value read from the counter for generating other random 2 etc. is the extracted random 2 etc. Hereinafter, a counter for generating random n (n: 1, 2,...) May be referred to as a random n counter.

  Next, the CPU 56 checks whether or not the value of the counter for generating the random 1 matches the value stored in the initial value buffer for random 1 as an initial value (step S104). If they do not match, the count value remains unchanged. If they match, random 6 (random 1 initial value determination random number) is extracted (step S105). That is, the count value of the counter for generating random 6 is input. Then, the extracted value is stored as an initial value in the initial value buffer for random 1 (step S106), and the extracted value is set in a counter for generating random 1 (step S107). Therefore, at this time, the initial value of the counter for generating random 1 is changed. When a game machine is turned on, “0” is generally stored as an initial value in a counter for generating random 1 and an initial value buffer for random 1, but a random 1 value is stored in a backup RAM. If it has been set, the stored value is restored when the power is turned on. A random 1 initial value buffer is also formed in the backup RAM. The game control means updates the numerical values of the determination numerical value updating means and the initial value numerical value updating means based on the numerical values held in the fluctuation data storage means when the power supply is restored.

  Next, the value of the counter for generating random 3 (big hit symbol determination random number) is incremented by 1 (step S108). When the value of the counter for generating random 3 is equal to or greater than (maximum value + 1) (step S109), the count value is returned to 0 (step S110). In this embodiment, (maximum value + 1) is 12.

  Also, the counter value for generating random 5 (normal random number for determination per symbol) is incremented by 1 (step S121). When the value of the counter for generating random 5 is equal to or greater than (maximum value + 1) (step S122), the count value is returned to 3 (step S123). In this embodiment, (maximum value + 1) is 14.

  Then, the CPU 56 checks whether or not the counter value for generating the random 5 matches the value stored in the random 5 initial value buffer as the initial value (step S124). If they do not match, the count value remains unchanged. If they match, random 7 (random 5 initial value determination random number) is extracted (step S125). That is, the count value of the counter for generating random 7 is input. Then, the extracted value is stored as an initial value in the initial value buffer for random 5 (step S126), and the extracted value is set in a counter for generating random 5 (step S127). Therefore, at this time, the initial value of the counter for generating random 5 is changed. When the game machine is turned on, “3” is set as an initial value to the counter for generating random 5, but if the value of random 5 is stored in the backup RAM, the power is turned on. Sometimes restored to saved value. A random 5 initial value buffer is also formed in the backup RAM.

  FIG. 16 is executed once in the game control process shown in FIG. 8 (step S25), and the remaining surplus time in the main process shown in FIG. It is a flowchart showing an example of an initial value random number update process (step S18) that is repeatedly executed at a time until the occurrence of the error.

  In the initial value random number update process, the CPU 56 increments the value of the counter for generating random 6 (random 1 initial value determining random number) (step S131). When the value of the counter for generating the random 6 is equal to or greater than (maximum value + 1) (step S132), the count value is returned to 0 (step S133). Note that (maximum value + 1) is 317 as in the case of random 1.

  Further, the counter value for generating random 7 (random 5 initial value determining random number) is incremented by 1 (step S134). When the value of the counter for generating random 7 is equal to or greater than (maximum value + 1) (step S135), the count value is returned to 3 (step S136). Note that (maximum value + 1) is 14 as in the case of random 5.

  FIG. 17 is executed once in the game control process shown in FIG. 8 (step S24), and is repeatedly executed in the surplus interruption time in the main process shown in FIG. 7 (step S17). It is a flowchart which shows an example of an update process.

  In the display random number update process, the CPU 56 increments the value of the counter for generating random 4 (variation pattern determining random number) (step S151). When the value of the counter for generating random 4 is 251 or more (step S152), the count value of the counter for generating random 4 is decreased by 251 (step S153).

  In this embodiment, the maximum value of random 4 is 250, but the count value of the counter for generating random 4 is increased by 3. Therefore, when the value starts from 0, it is 249. It becomes 252 after becoming. Then, when 251 is decreased, the value becomes 1. When the value starts from 1, it becomes 253 after it becomes 250. Then, when 251 is reduced, the value becomes 2. When the value starts from 2, it becomes 251 after becoming 248. Then, when 251 is decreased, the value becomes 0. That is, the initial value of the random 4 value (the value after the value is returned beyond the maximum value) is also somewhat random.

  Next, +1 is added to the counter value for generating random 2-1 (the left random symbol for random design determination) (step S154). When the value of the counter for generating random 2-1 is equal to or greater than (maximum value + 1) (step S155), the count value is returned to 0 (step S156). In this embodiment, (maximum value + 1) is 12.

  When the value of the counter for generating random 2-1 is equal to or greater than (maximum value +1) and the value is returned to 0, that is, when a carry occurs, random 2-2 (middle off symbol) The counter value for generating (decision random number) is incremented by 1 (step S157). When the value of the counter for generating random 2-2 is equal to or greater than (maximum value + 1) (step S158), the count value is returned to 0 (step S159). In this embodiment, (maximum value + 1) is 12.

  When the value of the counter for generating random 2-3 becomes (maximum value + 1) or more and the value is returned to 0, that is, when a carry occurs, random 2-3 (the right off-set symbol) The counter value for generating (decision random number) is incremented by 1 (step S160). When the value of the counter for generating random 2-3 is (maximum value + 1) or more (step S161), the count value is returned to 0 (step S162). In this embodiment, (maximum value + 1) is 12.

  FIG. 18 is an explanatory diagram showing an example of a counter value for generating random 1 (big hit determination random number) that changes by the determination random number update process shown in FIGS. 14 and 15. In this example, the first value of random 1 is 0. Since “0” is initially stored as an initial value, the count value advances to “316”, and when the count value is incremented by 1 and returns to 0 (steps S101, S102, S103), the process of step S104 is performed. It is detected that the count value matches the initial value. Then, random 6 (random 1 initial value determination random number) is extracted in the process of step S105. This time point is indicated by A in FIG.

  Here, it is assumed that the count value of the counter for generating the random 6 at that time is “19”. Then, “19” is extracted as random 6, the value is stored (step S106), and the value is set in the counter for generating random 1. Therefore, from this time point, the counter for generating random 1 advances from the initial value “19”.

  When the value of the counter for generating random 1 advances to “19”, it is detected in step S104 that the count value matches the initial value. Then, random 6 is extracted by the process of step S105. This time point is indicated by B in FIG. It is assumed that the count value of the counter for generating random 6 at that time is “195”. Then, “195” is extracted as random 6, the value is stored (step S106), and the value is set in the counter for generating random 1. Therefore, from this point, the counter for generating random 1 advances from the initial value “195”.

  When the value of the counter for generating random 1 advances to “195”, it is detected in step S104 that the count value matches the initial value. Then, random 6 is extracted by the process of step S105. This time point is indicated by C in FIG. Assume that the count value of the counter for generating random 6 at that time is “n”. Then, “n” is extracted as random 6, the value is stored (step S106), and the value is set in the counter for generating random 1. Therefore, from this point, the counter for generating random 1 advances from the initial value “n”. In FIG. 18, an asterisk (☆) indicates a position where the count value is “3 (big hit determination value at low probability)”.

  As described above, every time the value of the counter for generating random 1 makes one round (317 counts), a new initial value is set as the count value, and thereafter the counter advances from that value. A counter (counter for generating random 6) for determining an initial value of a counter for generating random 1 (a jackpot determining counter) is a surplus time of game control processing executed by the CPU 56 (game control processing is The time is counted up until the next 2 ms timer interrupt occurs). The extra time varies depending on the progress of the game, and is a random period. As a result, since the generated random 6 value is also a random value, the initial value of the jackpot determination counter also changes randomly.

  That is, every time the value of the big hit determination counter makes one round, the counter starts to increment from a random initial value. Then, even if the illegal board is connected to the main board 31 and the big hit determination count value update timing is recognized based on the signal output from the main board 31, the timing at which the big hit determination count value becomes the big hit determination value is set. It becomes difficult to send an illegal start winning signal to the main board 31 in order. This is because, according to this embodiment, as shown by the star in FIG. 18, the timing at which the jackpot determination count value becomes the jackpot determination value has no regularity and is random.

  FIG. 19 is a flowchart showing the normal symbol process (step S27) executed in the game control process shown in FIG. In the normal symbol process, the CPU 56 executes one of the processes shown in steps S72 to S76 according to the value of the normal symbol process flag after executing the gate switch process in step S71.

  As shown in FIG. 20, in the gate switch process, it is detected that the gate switch 32a is turned on based on the ball 32 passing through the ball 32, which is a condition for starting the normal symbol variation (step S611). If the gate switch 32a is on, it is checked whether or not the normal symbol start memory has reached the maximum value (“4” in this example) (step S612). If not reached, the value of the normal symbol start memory is incremented by 1 (step S613). The LED of the normal symbol start memory display 41 is turned on according to the value of the normal symbol start memory. Then, the CPU 56 extracts the value of the random number for determination per ordinary symbol (random 5) and stores the value (S614). The normal symbol start memory is formed in the backup RAM.

  In the normal symbol variation waiting process in step S72, the CPU 56 updates the value of the normal symbol process flag if the value of the normal symbol start storage is other than zero. If the value of the normal symbol start memory is 0, nothing is done.

  FIG. 21 is an explanatory diagram showing the relationship between the random number for normal symbol determination (random 7) and the hit / miss in this embodiment. As shown in FIG. 21, the hit value is any of 3 to 12 when the probability is high, and is 3, 5, or 7 when the probability is low. If the value of the random number for determination per normal symbol matches with the winning value, it is determined as winning. It should be noted that the high probability of a normal symbol coincides with, for example, the probability change.

  FIG. 22 is a flowchart showing the normal symbol determination process in step S73. In the normal symbol determination process, the CPU 56 reads the value stored in the random number storage area corresponding to the normal symbol start memory count = 1 (step S631), decreases the value of the normal symbol start memory by 1, and The value in the random value storage area is shifted (step S632). That is, the value stored in the random number storage area corresponding to the normal symbol start storage number = n (n = 2, 3, 4) is changed to the random value storage area corresponding to the normal symbol start storage number = n−1. Store.

  Then, the CPU 56 determines hit / miss based on the value read in step S631, that is, the value of the extracted random number for normal symbol determination (step S633). In other words, the hit / loss is determined based on the relationship shown in FIG. Specifically, when the value of the extracted random number for normal symbol per symbol matches one of the hit determination values shown in FIG. 21 (3, 5, 7 at low probability, 3-12 at high probability) Determined upon hitting. Then, a normal symbol stop symbol is determined based on a predetermined random number or the like (step S634). For example, if the normal symbol is a number from 0 to 9, if the winning symbol is “3” or “7”, the winning symbol is determined to be “3” or “7”. In the case of deviation, a value other than “3” and “7” is determined.

  Further, in order to notify the symbol control board 80 of the stop symbol of the normal symbol, control for transmitting a display control command indicating the stop symbol is performed (step S635). Specifically, a display control command indicating a stop symbol is stored in a predetermined storage area (RAM), and a command transmission request flag is set. The flag is referred to in the normal symbol command control process (step S29) in the game control process. Next, control for transmitting a display control command indicating the start of normal symbol variation is performed (step S636). Specifically, a display control command indicating the start of normal symbol variation is stored in a predetermined storage area (RAM), and a command transmission request flag is set.

  Then, the normal symbol variation time timer is started (step S637). For example, when the probability is high, a value corresponding to 5.1 seconds is set in the normal symbol variation time timer. When the probability is low, a value corresponding to 29.2 seconds is set in the normal symbol variation time timer. Also, the normal symbol process flag is updated to a value indicating the normal symbol variation process (step S638).

  The normal symbol variation control in the normal symbol display 10 is executed by display control means (the display control CPU 101 and peripheral circuits) mounted on the symbol control board 80. When receiving the display control command indicating the start of normal symbol variation, the display control means starts the variation of the normal symbol. And if the display control command which shows the below-mentioned normal symbol fluctuation | variation stop is received, the fluctuation | variation of a normal symbol will be stopped and the notified stop symbol will be displayed.

  In the normal symbol variation process of step S74, for example, as shown in FIG. 23, it is confirmed whether or not the normal symbol variation time timer has timed out (step S641). If timed out, the normal symbol process flag is updated to a value indicating the normal symbol stop process (step S642).

  In the normal symbol stop process in step S75, for example, as shown in FIG. 24, control for transmitting a display control command indicating normal symbol fluctuation stop is performed (step S651). When it is determined to win (step S652), the normal electric utility hit flag is set and the normal symbol process flag is updated to a value indicating the start winning opening / closing process (step S653). In the start winning opening / closing process, control for opening the starting winning opening (variable winning ball apparatus 15) for a predetermined period is performed a predetermined number of times. If it is determined to be off, the normal symbol process flag is updated to a value indicating the normal symbol variation waiting process (step S654).

  The opening pattern used in the start winning opening / closing process is, for example, a pattern in which the variable winning ball device 15 is opened only once for 0.2 seconds at a low probability. Further, when the probability is high, the variable winning ball apparatus 15 is opened for 1.15 seconds and then opened again for 1.15 seconds after a closing period of 4.4 seconds. The variable winning ball device 15 is controlled to open and close according to an opening pattern. In this embodiment, the variable winning ball device 15 as an ordinary electric accessory is also used as an electric accessory for opening and closing the start winning opening 14.

  FIG. 25 is an explanatory diagram showing an example of the value of the counter for generating random 5 (ordinary design random number per symbol) that is changed by the determination random number update process shown in FIGS. 14 and 15. In this example, the initial value of random 5 is 3. In addition, since “3” is initially set as an initial value, the count value advances to “13”, and when it is incremented by 1 and returns to 3 (steps S121, S122, and S123), the process of step S124 is performed. It is detected that the count value matches the initial value. Then, random 7 (random 5 initial value determining random number) is extracted in the process of step S125. This time point is indicated by A in FIG.

  Here, it is assumed that the count value of the counter for generating the random 7 at that time is “11”. Then, “11” is extracted as random 7 and the value is stored (step S126), and the value is set in the counter for generating random 5. Therefore, from this time point, the counter for generating the random number 5 advances from the initial value “11”.

  When the value of the counter for generating random 5 advances to “11”, it is detected in step S124 that the count value matches the initial value. Then, random 7 is extracted by the process of step S125. This time point is indicated by B in FIG. Assume that the count value of the counter for generating random 7 at that time is “8”. Then, “8” is extracted as random 7 and the value is stored (step S126), and the value is set in the counter for generating random 5. Therefore, from this point, the counter for generating random 5 advances from the initial value “8”.

  When the value of the counter for generating random 5 advances to “8”, it is detected in step S124 that the count value matches the initial value. Then, random 7 is extracted by the process of step S125. This time point is indicated by C in FIG. Assume that the count value of the counter for generating random 7 at that time is “m”. Then, “m” is extracted as random 7 and the value is stored (step S126), and the value is set in the counter for generating random 5. Therefore, from this point, the counter for generating random 5 advances from the initial value “m”. In FIG. 25, a star (☆) indicates a position where the count value is “5 (one of hit determination values)”.

  As described above, every time the value of the counter for generating random 5 makes one round (11 counts), a new initial value is set as the count value, and thereafter the counter advances from that value. A counter (counter for generating random 7) for determining an initial value of a counter for generating random 5 (ordinary symbol determination counter) is a surplus time for game control processing executed by the CPU 56 (game control). The time is counted up after the processing is completed until the next 2 ms timer interrupt is generated). The extra time varies depending on the progress of the game, and is a random period. As a result, the generated random 7 value also becomes a random value, so that the initial value of the normal symbol per-determination counter also changes randomly.

  That is, every time the value of the counter for normal symbol determination makes one round, the counter starts to increment from the random initial value. Then, even if the illegal board is connected to the main board 31 and the normal symbol per-determination count value update timing is recognized based on the signal output from the main board 31, the normal symbol per-determination count value is the hit determination value. It is difficult to send an illegal start winning signal to the main board 31 at the timing. This is because, according to this embodiment, as indicated by the asterisk in FIG. 25, the regular symbol per-determination count value becomes random with no regularity at the timing when it becomes the hit determination value.

When a winning is made at the center start winning opening 204b among the openings 204a to 204c, the variable winning ball apparatus 220 is opened twice. The state in which the variable winning ball apparatus 220 performs the opening operation in response to the winning detection of the starting ball detectors 205a to 205c in this way is referred to as a starting operation state. In addition to the configuration described above, the game area 203 includes windmills 206a and 206b incorporating windmill lamps 207a and 207b, windmills 208a and 208b, side lamp decorations 209a and 209b incorporating side lamps 210a and 210b, and an outlet. 211 etc. are provided.

The winning balls detected by the winning ball detectors 225a and 225b pass through the winning ball detectors 225a and 225b, and then pass through the ball passages 226a and 226b formed on the left and right sides of the mounting substrate 221. 227a and 227b are sent to the lower winning space 230.

  It should be noted that the structure of the variable winning ball apparatus 220 shown in FIGS. 27 and 28 is an example, and a variable winning ball apparatus having another structure can also be used.

  In addition, on the rear wall in the upper winning space 222, a winning number display 228 for displaying the number of winning balls detected by the winning ball detectors 225a and 225b and a continuation number indicator for displaying the number of continuations of the round in a specific gaming state. 229 is provided.

  In the lower winning space 230, a lower rolling plate 231 that rolls the winning balls fed from the ball discharge ports 227a and 227b rearward, and an opening 232 formed at the downstream end of the lower rolling plate 231; An opening / closing plate 234 that opens and closes the opening 232, a rotating drum 236 that rotates at a position above the opening / closing plate 234, and an upper rolling plate 240 disposed at the rear of the upper end of the rotating drum 236 are provided. A solenoid 235 is connected to the opening / closing plate 234 and moves forward in a direction in which the opening 232 is closed when the solenoid 235 is turned on. Further, when the solenoid 235 is turned off, the solenoid 235 moves backward in a direction to open the opening 232.

  A motor 238 is also connected to the rotating drum 236 via the connecting gears 237 a to 237 c, and always rotates in one direction at a constant speed according to the driving of the motor 238. However, the motor 238 can also rotate in the reverse direction.

  In addition, permanent magnets 239a to 239c are installed on the circumferential surface of the rotating drum 236 at three positions in the horizontal row of left, middle, and right. Accordingly, when the opening 232 is closed by the opening / closing plate 234, the rotating drum 236 attracts the game ball stopped on the opening plate 234 by the magnetic force of the permanent magnets 239a to 239c, and the attracted game ball is accompanied with the rotation operation. It feeds into the upper rolling plate 240.

  On the rear side of the upper rolling plate 240, inclined portions 240a and 240b that are inclined downward in the left-right direction with respect to the center are formed, and on the downstream side (left and right sides) of the inclined portions 240a and 240b, inclined portions are formed. Ball paths 241a and 241b are formed in which the game balls that have rolled 240a and 240b are again fed onto the lower rolling plate 31.

Is attached. The connecting member 246 converts the advance / retreat operation of the plunger 245a constituting the solenoid 245 into the rotation operation of the rotation shafts 244a, 244b (movable members 243a, 243b). When the solenoid 245 is turned on, the movable members 243a and 243b rotate in a direction that blocks the front of the specific receiving port 242 (the arrow direction shown in FIG. 27). In addition, when the solenoid 245 is turned off, the solenoid 245 rotates in a direction to release the blocking in front of the specific receiving port 242.

  A plurality of decorative LED indicators 247 are provided on the outer periphery of the specific receiving port 242. Further, a specific ball detector 248 is provided inside the specific receiving port 242 as specific detecting means for detecting a winning ball that has entered the specific receiving port 242. On the downstream side of the specific ball detector 248, a ball passage (not shown) for discharging the detected ball through a position below the opening / closing plate 234 is formed. In the following description, the fact that a game ball has won the specific receiving port 242 and has been detected by the specific ball detector 248 is also referred to as V winning.

  FIG. 29 is a block diagram showing an example of a circuit configuration of the game control board (main board) 31 installed on the back surface of the gaming machine. 29 also shows a payout control board 37, a lamp control board 35, a sound control board 70, a launch control board 91, and a symbol control board (hereinafter also referred to as a display control board) 80. The main circuit board 31 includes a basic circuit 53 for controlling a pachinko machine according to a program, and detection signals from a specific ball detector 248, start ball detectors 205a to 205c, winning ball detectors 225a and 225b, and a clear switch 921. A switch circuit 58 to be supplied to the circuit 53 is mounted.

  The main board 31 includes a solenoid circuit 59 that drives the solenoids 224a, 224b, 235, and 245 in accordance with commands from the basic circuit 53, and a motor circuit 60 that drives the motor 238 in accordance with commands from the basic circuit 53. ing. In addition, an information output circuit 64 for outputting an information output signal such as jackpot information indicating the occurrence of a jackpot to an external device such as a hall computer in accordance with data given from the basic circuit 53 is mounted.

  The basic circuit 53 includes a ROM 54 for storing a game control program and the like, a RAM 55 as storage means (means for storing variation data) used as a work memory, a CPU 56 for performing control operations according to the program, and an I / O port unit 57. including. In this embodiment, the ROM 54 and RAM 55 are built in the CPU 56. That is, the CPU 56 is a one-chip microcomputer. The one-chip microcomputer only needs to incorporate at least the RAM 55, and the ROM 54 and the I / O port unit 57 may be externally attached or built-in.

  Further, a part or all of the RAM (may be a CPU built-in RAM) 55 is a backup RAM that is backed up by a backup power source created in the power supply substrate 910. That is, even if the power supply to the gaming machine is stopped, a part or all of the contents of the RAM 55 is saved for a predetermined period.

  In this embodiment, the lamp control means mounted on the lamp control board 35 controls various light emitting members such as the side lamps 210a and 210b, the windmill lamps 207a and 207b, the LED display 247, and other frame decoration lamps. A signal is output to control the operation of various light emitting members in a predetermined manner. In addition, display control of the winning number display 228, the continuous number display 229, and the normal symbol display 10 is performed by display control means mounted on the display control board 80. The sound control means mounted on the sound control board 70 controls the speaker 27. The ball payout device 97 for paying out game balls as prizes is controlled by payout control means mounted on the payout control board 37. The lamp control means and the sound control means may be mounted on one board. Further, the display control means, the lamp control means, and the sound control means may be mounted on one substrate.

  Further, as in the case of the first embodiment, a power supply board 910 on which a backup power supply is mounted is also installed on the back of the gaming machine.

  Next, the operation control of the variable winning ball apparatus 220 by the game control means will be described. When the starting operation state occurs, the solenoids 224a and 224b are turned on for a predetermined time, and the open / close pieces 223a and 223b are opened. When the game ball wins in the upper winning space 222 during the opening operation, the winning ball is sent to the lower winning space 230 through the winning ball detectors 225a and 225b. Further, the opening / closing plate 234 moves in a direction to close the opening 232 until a predetermined time elapses after the winning ball detectors 225a and 225b detect the winning ball by the ON control of the solenoid 235 by the game control means. When the game ball sent into the lower prize space 230 is attracted to any one of the permanent magnets 239a to 239c of the rotary drum 236 within the closing time of the opening 232, the upper ball rolls with the rotation of the rotary drum 236. It is fed into the plate 240.

  At this time, when the game ball stopped on the opening / closing plate 234 is attracted to the left and right permanent magnets 239a and 239c, the game ball is sent to the ball passages 241a and 241b with a probability of 100%. At this time, the opening / closing plate 234 has moved in a direction to open the opening 232 by the off control of the solenoid 235 by the game control means. Then, the balls sent to the ball passages 241a and 241b pass through the lower rolling plate 231 and fall through the opening 232 and are discharged. On the other hand, when the game ball stopped on the opening / closing plate 234 is attracted to the central permanent magnet 239b, the game ball is sent to the specific receiving port 242 with a fairly high probability (not 100%). Then, the game balls (game balls that have won the V prize) sent to the specific receiving port 242 pass through the specific ball detector 248 and are discharged. At this time, the specific game state is generated based on the passage of the game ball in the specific ball detector 248 (detection of the game ball by the specific ball detector 248).

  In the specific gaming state, the game control means controls the solenoid 235 to be turned on / off, whereby the opening / closing pieces 223a and 223b repeat the opening operation for a predetermined time 18 times (18 opening / closing cycles). If ten winning balls are detected by the winning ball detectors 225a and 225b before the opening / closing cycle ends 18 times, the opening / closing operation of the opening / closing pieces 223a and 223b is ended at that time. Further, during the open / close cycle of the open / close pieces 223a, 223b, the solenoids 235, 245 are always turned on, so that the open / close plate 234 always closes the opening 232, and the movable members 243a, 243b are always open except for the final cycle. The front of the specific receiving port 242 is blocked (the winning to the specific receiving port 242 becomes impossible).

  Therefore, the game ball that has won the variable winning ball device 220 during the open / close cycle does not fall through the opening 232 until the end of the open / close cycle. Therefore, when the game ball stopped on the opening / closing plate 234 is attracted by the left and right permanent magnets 239a, 239c, the game ball is sent to the lower rolling plate 231 through the ball passages 241a, 241b and is opened / closed again. Stopped on the plate 234. On the other hand, when the game ball stopped on the opening / closing plate 234 is attracted to the central permanent magnet 239b, the winning ball is received by the movable members 243a and 243b in front of the specific receiving port 242.

  Then, with the end of the opening / closing cycle (after the opening / closing cycle, waiting for a sufficient time for all the winning game balls to be detected by the winning ball detectors 225a, 225b), or at the last round of the opening / closing cycle When the solenoids 235 and 245 are turned off, the opening / closing plate 234 opens the opening 232, and the movable members 243a and 243b release the blocking in front of the specific receiving port 242. Accordingly, the winning ball received by the movable members 243a and 243b rolls straight back on the upper rolling plate 240 and enters the specific receiving port 242. Then, the game ball that has entered the specific receiving port 242 (the game ball that has won V) passes through the specific ball detector 248, thereby establishing the right to continue 18 open / close cycles. When the right to continue is established, the opening and closing pieces 223a and 223b are opened again after a predetermined interval time has elapsed. That is, the next round is started.

  The maximum number of continuous open / close cycles is 15 (15 rounds). In such a specific gaming state, the continuation number display 229 displays the continuation number (round number) of the open / close pieces 223a and 223b, and the winning number display unit 228 displays the winning number for each round.

  Next, the operation of the gaming machine will be described. Game control means (CPU 56 and peripheral circuits such as ROM and RAM) on the main board 31 is the same as the process shown in FIG. 7 when the game machine is powered on and the input level of the reset terminal becomes high. The main process starts.

  When a timer interrupt occurs after completion of the initialization process (steps S11 to S15) in the main process, the CPU 56 performs the register saving process (step S80) shown in FIG. The game control process of steps S81 to S92 is executed. In the game control process, the CPU 56 first inputs detection signals of the switches of the specific ball detector 248, the starting ball detectors 205a to 205c, and the winning ball detectors 225a and 225b via the switch circuit 58, and the state thereof. A determination is made (switch processing: step S81).

  Next, various abnormality diagnosis processing is performed by a self-diagnosis function provided in the pachinko gaming machine, and an alarm is issued if necessary according to the result (error processing: step S82).

  Next, a process of updating the count value of each counter for generating each determination random number such as a hit determination random number used for game control is performed (step S83). The CPU 56 further performs a process of updating the count value of the counter for generating the display random number and the initial value random number (steps S84 and S85). In this embodiment, among the random numbers shown in FIG. 13, there is a normal random number for each symbol shown in FIG. 13, and the stop in the normal symbol display 10 that is not illustrated in FIG. 13 as the display random number. There is a random number for determining a design, and there is a random 5 initial value random number shown in FIG. 13 as an initial value random number. That is, also in this embodiment, among the random numbers shown in FIG. 13, those corresponding to random numbers 5 and 7 are used. In this embodiment, a big hit determination random number or the like is not used.

  Further, the CPU 56 performs process processing (step S86). In the process control, corresponding processing is selected and executed according to a process flag for controlling the pachinko gaming machine in a predetermined order according to the gaming state. The value of the process flag is updated during each process according to the gaming state.

  Further, normal symbol process processing is performed (step S87). In the normal symbol process, the corresponding process is selected and executed according to the normal symbol process flag for controlling the display state of the normal symbol display 10 in a predetermined order. The value of the normal symbol process flag is updated during each process according to the gaming state. The normal symbol process can be executed in the same manner as in the first embodiment (see FIG. 19).

  Next, the CPU 56 performs a process of setting the display control command in a predetermined area of the RAM 55 and transmitting the display control command (command control process: step S88). Further, the CPU 56 performs information output processing for outputting data such as jackpot information and start information supplied to the hall management computer, for example (step S89).

  Further, the CPU 56 issues a drive command to the solenoid circuit 59 when a predetermined condition is satisfied (step S90). Further, a signal for instructing driving of the motor 38 is given to the motor circuit 60 (step S91).

  Then, the CPU 56 executes prize ball processing for setting the number of prize balls based on detection signals from the winning ball detectors 225a, 225b, etc. (step S92). Specifically, a payout control command indicating the number of prize balls is output to the payout control board 37 in response to winning detection based on the winning ball detectors 225a, 225b being turned on. The payout control CPU 371 mounted on the payout control board 37 drives the ball payout device 97 according to a payout control command indicating the number of prize balls. Thereafter, the contents of the register are restored (step S93), and the interrupt permission state is set (step S94).

  With the above control, in this embodiment, the game control process is started every 2 ms. In this embodiment, the game control process is executed by the timer interrupt process. However, in the timer interrupt process, for example, only a flag indicating that an interrupt has occurred is set, and the game control process is performed by the main process. May be executed.

  FIG. 31 is a flowchart showing an example of the determination random number update process (step S83) executed in the game control process shown in FIG. In the determination random number update process, the CPU 56 increments the value of the counter for generating random 5 (normal determination random number per symbol) by 1 (step S201). When the value of the counter for generating random 5 is equal to or greater than (maximum value + 1) (step S202), the count value is returned to 3 (step S203). In this embodiment, (maximum value + 1) is 14.

  It is confirmed whether or not the value of the counter for generating random 5 matches the value stored in the initial value buffer for random 5 as an initial value (step S204). If they do not match, the count value remains unchanged. If they match, random 7 (random 5 initial value determination random number) is extracted (step S205). That is, the count value of the counter for generating random 7 is input. Then, the extracted value is stored as an initial value in the initial value buffer for random 5 (step S206), and the extracted value is set in a counter for generating random 5 (step S207). Therefore, at this time, the initial value of the counter for generating random 5 is changed. When the power is turned on to the gaming machine, “3” is generally stored in the random initial value buffer as an initial value, but when the random number 5 is stored in the backup RAM, it is stored when the power is turned on. Returned to value. A random 5 initial value buffer is also formed in the backup RAM.

  FIG. 32 is executed once in the game control process shown in FIG. 30 (step S85), and the interrupt surplus time in the main process shown in FIG. It is a flowchart showing an example of an initial value random number update process (step S18) that is repeatedly executed at a time until the occurrence of the error.

  In the initial value random number update process, the CPU 56 increments the value of the counter for generating random 7 (random 5 initial value determination random number) (step S211). When the value of the counter for generating random 7 is equal to or greater than (maximum value + 1) (step S212), the count value is returned to 3 (step S213). Note that (maximum value + 1) is 14 as in the case of random 5.

  Also in this embodiment, with respect to step S87 (ordinary symbol process) in the game control process, the process as shown in FIG. 19 is executed. That is, the processing as shown in FIG. 19 is executed with respect to the display control of the normal symbol display 10 and with respect to the opening / closing control of the variable winning ball device 15 (start winning prize opening 204b). Then, by executing the processing shown in FIGS. 31 and 32, the initial value of Random 5 for determining whether or not the symbol stopped and displayed on the normal symbol display 10 is a winning symbol is random. Become. For example, the counter value for generating random 5 (ordinary design random number per symbol) that is changed by the determination random number update process illustrated in FIG. 25 is also applicable to this embodiment. As indicated by the mark, there is no regularity at the timing when the count value for determination per normal symbol becomes the hit determination value, and it becomes random.

  As a result, even if the illegal board is connected to the main board 31 and the normal symbol per-determination count value update timing is recognized based on the signal output from the main board 31, the normal symbol per-determination count value is determined to be hit. It is difficult to send an illegal start winning signal to the main board 31 in order to reach the timing of the value.

  In this embodiment, when the stop symbol in the normal symbol display 10 is a winning symbol, the variable winning ball apparatus 15 is in an open state, and it becomes easy to win the start winning hole 204b. As described above, when winning at the start winning opening 204b, the variable winning ball apparatus 220 is opened twice. That is, when a winning is made at the start winning opening 204b, the possibility that a specific gaming state will occur is further increased. Therefore, the cheating person wants to generate more open states of the variable winning ball device 15 and tries to cheat so that the stop symbol of the normal symbol display 10 becomes the winning symbol. In the embodiment, such illegal acts can be effectively prevented.

Embodiment 3 FIG.
In each of the above embodiments, the first type pachinko gaming machine or the second type pachinko gaming machine is taken as an example, but the present invention can also be applied to a third type pachinko gaming machine. FIG. 33 is a front view of the gaming board 401 of the third type pachinko gaming machine of the normal symbol type as seen from the front. The game board 401 is detachably attached to the main body of the pachinko gaming machine.

  As shown in FIG. 33, a guide rail 402 is provided on the front surface of the game board 401 for guiding the hit ball. A game area 403 is provided in front of the game board 401. Near the center of the game area 403, a normal symbol display device 410 using 7-segment LEDs is provided. The normal symbol display device 410 is attached to the front surface of the game board 401 by an attachment substrate 411 formed on the back surface. The normal symbol display device 410 is provided with an LCD display (liquid crystal display device) 412 having three symbol display areas of “left”, “middle”, and “right”. A display window 411 a having a window frame surrounding three symbol display areas is formed on the mounting substrate 411. On the top of the mounting substrate 411, a winning opening 413 and a normal symbol start memory display 414 made up of four LEDs are provided. In this embodiment as well, with the upper limit of four, the normal symbol start memory display 414 increases the number of lit display units one by one each time passage detection is performed by a start ball detection switch 405 described later. Each time the normal symbol variable display on the normal symbol display device 410 is started, the number of lit display portions is reduced by one.

  A starting ball passage port (gate) 404 is provided below the normal symbol display device 410. The hit ball that has passed through the start ball passage port 404 is detected by a start ball detection switch (gate switch) 405 provided in the start ball passage port 404. In this embodiment, the symbol display area of the normal symbol display device 410 is controlled to start changing in response to the start ball detection switch 405 detecting a hit ball. A winning port 406 is provided below the starting ball passage port 404. The winning hole 406 receives the hit ball that has passed through the starting ball passage opening 404 as a winning ball.

  A rotating body 420 is disposed on the right side of the normal symbol display device 410. The rotating body 420 has a mounting plate that is attached to the front surface of the game board 401. The surrounding frame projects from the front surface of the mounting plate and is rotated in the clockwise direction by a motor inside the surrounding frame. ing. A ball receiving recess 421 for receiving one hit ball is formed on the outer peripheral portion of the rotating body 420. The ball receiving recess 421 is configured to be able to receive a hit ball entered from an operation winning opening 422 (an example of a starting region) formed on the upper portion of the surrounding frame by the rotation of the rotating body 420. The hit ball received by the ball receiving recess 421 is guided to the back surface of the mounting plate, and is detected by the operating ball detection switch 423 (an example of the start detection means). When the working ball detection switch 423 detects a hit ball during the right generation state, a big hit gaming state (specific gaming state) in which a variable winning ball device 450 described later is controlled to open is generated.

  On the left side of the normal symbol display device 410, a variable winning detection device 430 is provided. In the variable winning detection device 430, a winning ball is detected by the winning ball detection switch 431. An ordinary variable winning opening 432 is provided at the upper end portion of the variable winning detection device 430. The normal variable prize winning opening 432 is provided with a pair of left and right opening / closing pieces 433a and 433b. The open / close pieces 433a and 433b can be changed between a tilt position and a vertical position based on driving of a solenoid (not shown) arranged on the back surface of the game board 401. Further, an obstacle nail 434 for preventing the hitting of the hit ball into the normal variable winning opening 432 is provided above the open / close pieces 433a and 433b in the vertical position. As a result, the open / close pieces 433a and 433b are tilted to open the normally variable winning opening 432 when the solenoid is on, and are vertically closed to close the normally variable winning opening 432 when the solenoid is off. At the lower end portion of the variable winning detection device 430, a winning ball passing port 435 through which the hit ball detected by the winning ball detection switch 431 passes is provided.

  A distribution device 436 that receives a hit ball from the winning ball passing port 435 and determines whether or not a right generation state has occurred is provided below the winning ball passing port 435. In this embodiment, the variable prize detecting device 430 and the distribution device 436 constitute a variable winning ball device. In this embodiment, the variable winning ball device constituted by the variable winning detection device 430 and the sorting device 436 corresponds to an electric accessory that is opened based on the display result on the normal symbol display device 410.

  FIG. 34 is an explanatory diagram showing a configuration example of the sorting device 436. As shown in FIG. 34, in the sorting device 436, a winning space in which a hit ball from the winning ball passing port 435 is received is formed by a winning space forming member 437. The winning space forming member 437 has a C-shaped frame portion 437a, a winning opening 437b, and a transparent front cover portion 437c. A winning ball retaining member 438 having a pair of left and right retaining recesses 438a at the front end is provided at substantially the center of the winning space formed by the winning space forming member 437. The winning ball stopping member 438 operates in the front-rear direction with respect to the game board 401 by driving a solenoid (not shown) provided on the back side. When the solenoid is turned on and the winning ball stopping member 438 is positioned forward, the stopping recess 438a is projected into the winning space. When the solenoid is turned off and the winning ball stopping member 438 is located rearward, the stopping recess 438a enters the inside of the game board 401 and is in a state of being immersed from the winning space. Above the winning ball stopping member 438, there is provided a specific winning port 439 for guiding a hit ball in the winning space to a specific ball detecting switch (not shown) on the back of the game board 401.

  Further, below the winning ball stopping member 438, an ordinary winning port 440 for processing a hit ball that has not entered the specific winning port 439 as a normal winning ball is provided. A specific winning opening 439 for guiding a hit ball in the winning space is provided on a specific ball detection switch (not shown) on the back of the game board 401. A guide protrusion 437 d for guiding a hit ball to the specific winning opening 439 is formed on the front surface covering portion 437 c positioned in the front portion of the specific winning opening 439.

  Here, the operation of the winning ball in the distribution device 436 will be described. When the display result of the normal symbol display device 410 is a winning symbol, the open / close pieces 433a and 433b are driven to open the variable winning opening 432 for a predetermined time. When the hit ball is won from the variable winning opening 432, the first and second winning balls are stopped on the stopping recess 438a protruding from the game area 403 as shown in FIG. Next, when there is a third winning ball, the third winning ball is guided to the specific winning port 439 by the first and second winning balls and the guide protrusion 437d. Then, the third winning ball is detected by the specific ball detection switch, and a right generation state is generated. It should be noted that the first and second winning balls stopped on the stopping recess 438a are released from the stopping recess 438a by moving the stopping recess 438a backward after a predetermined time has elapsed, so that the normal winning is achieved. It is guided to the mouth 440 and processed as a normal winning ball.

  Next, the configuration of the variable winning ball device 450 provided at the lower position of the normal symbol display device 410 will be described. The variable winning ball device 450 has an attachment board 451 attached to the surface of the game board 401. A special variable winning opening 451a is provided at the center of the mounting substrate 451. In this embodiment, an opening / closing member 452 is provided in the special variable winning opening 451a, and the opening / closing member 452 serves as a means for opening and closing the special variable winning opening (large winning opening) 451a. The opening / closing member 452 is opened by the solenoid 453 in the big hit state. A winning ball guided to the back of the game board 401 from the special variable winning port 451a is detected by a winning ball detection switch 454. In addition, normal winning holes 455 are provided on the left and right sides of the special variable winning hole 451a.

  Further, the game board 401 is provided with a winning opening 460, and the winning of the game ball to the winning opening 460 is detected by a corresponding winning opening switch. Left and right windmills with side lamp decorations 461 and windmill lamps 462 are provided around the left and right sides of the game area 403, and an outlet 463 that absorbs a hit ball that has not won a prize is provided at the lower part. A plurality of speakers (not shown) that emit sound effects are provided on the left and right upper portions outside the game area 403. Further, on the outer periphery of the game area 403, although not shown, a light emitting body such as a prize ball lamp that is turned on when the prize ball is paid out, a ball-out lamp that is turned on when the supply ball is cut out, and a game effect LED is provided. .

  Next, the operation of the pachinko gaming machine in this embodiment will be described. The hit ball fired from the hit ball launching device enters the game area 403 through the guide rail 402 and then descends the game area 403. When the hit ball is detected by the start ball detection switch 405 through the start ball passing port 404, the symbol (3) displayed on the three symbol display units of the normal symbol display device 410 (if the symbol can be changed) is displayed. For example, the number) changes continuously. If it is not in a state where the change of the symbol can be started, the normal symbol start memory is increased by one.

  The rotation of the image in the normal symbol display device 410 stops when a certain time has elapsed. When the combination of symbols at the time of stop becomes a combination of right generation symbols (winning symbol), the open / close pieces 433a and 433b of the variable winning detection device 430 are opened until a predetermined time elapses, and the winning ball is guided to the sorting device 436. . Next, when a hitting ball is guided to the specific winning hole 439 in the winning space of the distribution device 436 and led to the specific ball detecting switch, the right is generated. When the right generation state continues, when the hit ball wins the ball receiving recess 421 of the rotator 420 and the operation ball detection switch 423 is turned on, a big hit state is generated and the special variable winning of the variable winning ball device 450 is generated. The mouth 451a is opened. If the right generation state continues, the big hit state is repeated every time the hit ball wins the ball receiving recess 421 of the rotating body 420 (open cycle). However, the continuation of the right generation state is performed when a hit ball is again guided to the specific ball detection switch in the winning space during the right generation state, or a predetermined number (for example, 16) of the winning balls is set in the operation ball detection switch 423. It ends when it is detected.

  Also in this embodiment, a power supply board having a game control board (main board), a payout control board, a lamp control board, a sound control board, a launch control board, a symbol control board, a backup power supply, etc. Is installed. As in the first and second embodiments, game control means realized by peripheral circuits such as the CPU 56, ROM 54, and RAM 55 are mounted on the main board, and the game control means controls the progress of the game.

  Next, the operation of the gaming machine will be described. The game control means on the main board starts main processing similar to the processing shown in FIG. 7 when power is turned on to the gaming machine and the input level of the reset terminal becomes high.

  When the timer interruption occurs after the completion of the initialization process (steps S11 to S15) in the main process, the game control means performs the register saving process (step S310) shown in FIG. The game control process of steps S311 to S322 shown in FIG. In the game control process, the game control means first inputs a detection signal of a switch such as a winning ball detection switch 431 and makes a state determination thereof (switch process: step S311).

  Next, various abnormality diagnosis processing is performed by a self-diagnosis function provided in the pachinko gaming machine, and an alarm is issued if necessary according to the result (error processing: step S312).

  Next, a process of updating the count value of each counter for generating each determination random number such as a hit determination random number used for game control is performed (step S313). The game control means further performs a process of updating the count value of the counter for generating the display random number and the initial value random number (steps S314 and S315). In this embodiment, there is a normal random number for each symbol shown in FIG. 13 as a random number for determination, and a stop in the normal symbol display device 410 that is not illustrated in FIG. 13 as a random number for display. There is a random number for determining a design, and there is a random 5 initial value random number shown in FIG. 13 as an initial value random number. That is, also in this embodiment, among the random numbers shown in FIG. 13, those corresponding to random numbers 5 and 7 are used. In this embodiment, a big hit determination random number or the like is not used.

  Further, the game control means performs process processing (step S316). In the process control, corresponding processing is selected and executed according to a process flag for controlling the pachinko gaming machine in a predetermined order according to the gaming state. The value of the process flag is updated during each process according to the gaming state.

  Further, normal symbol process processing is performed (step S317). In the normal symbol process, the corresponding process is selected and executed according to the normal symbol process flag for controlling the display state of the normal symbol display device 410 in a predetermined order. The value of the normal symbol process flag is updated during each process according to the gaming state.

  Next, the game control means performs a process of setting the display control command in a predetermined area of the RAM 55 and transmitting the display control command (command control process: step S318). Further, the game control means performs an information output process for outputting data such as jackpot information and start information supplied to the hall management computer, for example (step S319).

  Further, the game control means outputs a drive command to the solenoid when a predetermined condition is satisfied (step S320). Further, a signal for instructing driving of each motor is given to each motor (step S321).

  Then, the game control means executes prize ball processing for setting the number of prize balls based on detection signals from the winning ball detection switches 431, 454, etc. (step S322). Specifically, a payout control command indicating the number of winning balls is output to the payout control board in response to winning detection based on the winning ball detection switches 431 and 454 being turned on. The payout control CPU mounted on the payout control board drives the ball payout device in accordance with a payout control command indicating the number of winning balls. Thereafter, the contents of the register are restored (step S323), and the interrupt enabled state is set (step S324).

  With the above control, in this embodiment, the game control process is started every 2 ms. In this embodiment, the game control process is executed by the timer interrupt process. However, in the timer interrupt process, for example, only a flag indicating that an interrupt has occurred is set, and the game control process is performed by the main process. May be executed.

  Also in this embodiment, the determination random number update process (step S313) executed in the game control process shown in FIG. 35 is executed as illustrated in FIG. The initial value random number update processing is executed as illustrated in FIG. 32, and is executed once in the game control processing shown in FIG. 35 (step S325), and the main processing shown in FIG. This is repeatedly executed in the surplus interrupt time (time from the end of the game control process until the next 2 ms timer interrupt is generated) (step S18).

  Therefore, also in this embodiment, by executing the processing shown in FIG. 31 and FIG. 32, a random number 5 for determining whether or not the symbol that is normally stopped and displayed on the symbol display device 410 is used as a winning symbol is determined. The initial value of is random. For example, the counter value for generating random 5 (ordinary design random number per symbol) that is changed by the determination random number update process illustrated in FIG. 25 is also applicable to this embodiment. As indicated by the mark, there is no regularity at the timing when the count value for determination per normal symbol becomes the hit determination value, and it becomes random.

  As a result, even if the illegal board is connected to the main board and the count value update timing for determining the normal symbol per unit is recognized based on the signal output from the main board, the count value for determining the normal symbol per unit is changed to the hit determination value. It is difficult to send an illegal start winning signal to the main board at the timing.

  In this embodiment, when the display result of the normal symbol display device 410 is a winning symbol, the variable winning opening 432 in the variable winning ball device as an ordinary electric accessory is opened for a predetermined time, resulting in a right generation state. It gets wet. Therefore, the cheating person wants to generate more open states of the variable winning opening 432 in the variable winning ball device, and therefore performs the cheating so that the stop symbol of the normal symbol display device 410 becomes the winning symbol. However, in this embodiment, such illegal acts can be effectively prevented.

Embodiment 4 FIG.
FIG. 36 is a front view of the game board 501 of the third type pachinko gaming machine of the judgment symbol type as seen from the front. The game board 501 is detachably attached to the main body of the pachinko gaming machine.

  The game ball launched from the hitting ball launching device passes between the outer rail 501 and the inner rail 502 and enters the game area 507, and then descends the game area 507. When the game ball passes through the gate 511 and is detected by the gate switch 511a, variable display on the normal symbol display 510 is started. In this embodiment, the normal symbol display 510 is made up of two lamps each having a symbol (in this example, ◯ and X) drawn thereon, and the two lamps are alternately lit to perform variable display. . Then, when the variable display is completed in a state where the ○ lamp is stopped, it is a win.

  When winning, the ordinary electric accessory 550 is activated and the specific winning opening 532 is opened. The game ball in which the game ball has won the specific winning port 532 is detected by the specific winning port switch 532a and enters the sorting member 535. Thereafter, when the special device operation determination symbol gate 541 in the guide unit 540 passes, the determination symbol starts variable display in the variable display device 512. The special device operation determination symbol gate 541 is provided with a symbol gate switch 541a as an operation detection means for detecting a game ball that has passed through the special device operation determination symbol gate 541. Further, during the change of the determination symbol in the variable display device 512, the game ball is stopped in the concave portion of the guide member 542 below the special device operation determination symbol gate 541.

  In the game area 507, the game balls won in the normal winning holes 513, 514, 515, 516 are detected by the winning hole switches 513a, 514a, 515a, 516a, respectively. When a game ball is detected by the winning port switch 513a, 514a, 515a, 516a and the specific winning port switch 532a, a predetermined number of gaming balls are paid out as a prize.

  If the variable display result (stop symbol) of the determination symbol in the variable display device 512 is a hit symbol, a hit occurs, and the game ball that has stopped in the recess of the guide member 542 is guided to the special device operation region 544 by the guide device. The Then, a right is generated when detected by the sensor 544a provided in the special device operation area 544, and when the game ball wins the start port in the start winning device 520 in the right generation state, the game ball is started by the start port switch 520a. Detected by. Then, the big winning opening is opened, and the game shifts to a big hit gaming state in which a hit ball is easy to win. When the variable display result (stop symbol) of the determination symbol in the variable display device 512 is an off symbol, the game ball stopped in the recess of the guiding member 542 is guided to the normal area 543. The starting prize-winning device 520 is provided with a rotating body 521, and an opening / closing plate 551 for opening a large winning opening forming a special electric accessory is provided below the rotating body 521 in the starting prize-winning device 520. Yes. When the game ball is rotated by the rotating body 521 and detected by the start port switch 520a, the start port is won. Further, when the opening / closing plate 551 is in the open state, the big prize opening is opened.

  When a predetermined number (for example, 10) of game balls wins the big winning opening during the opening period, the big winning opening is closed. And as long as the rights continue, the big prize opening is opened again. The right continues until, for example, 16 game balls are won at the start opening. However, if an operation for generating a right again (winning a game ball in the special device operation area) is performed during the continuation of the right, the right is lost. An opening time (for example, 29.5 seconds) is determined for each opening, and even if the number of winnings does not reach a predetermined number, the big winning opening is closed when the opening time elapses.

  In addition, a game ball that has won a big winning opening while a right is being generated is detected by the count switch 551a. When a game ball is detected by the count switch 551a, a predetermined number of game balls are paid out as a prize. When the number of game balls detected by the count switch 551a reaches a predetermined number, the special winning opening is closed.

  Also in this embodiment, a power supply board having a game control board (main board), a payout control board, a lamp control board, a sound control board, a launch control board, a symbol control board, a backup power supply, etc. Is installed. As in the first and second embodiments, game control means realized by peripheral circuits such as the CPU 56, ROM 54, and RAM 55 are mounted on the main board, and the game control means controls the progress of the game. Further, the normal symbol and the determination symbol may be variably displayed on one variable display device.

  Next, the operation of the gaming machine will be described. The game control means on the main board starts main processing similar to the processing shown in FIG. 7 when power is turned on to the gaming machine and the input level of the reset terminal becomes high.

  When timer interruption occurs after the completion of the initialization process (steps S11 to S15) in the main process, the game control means performs the register saving process (step S310) shown in FIG. The game control process of steps S331 to S342 shown in FIG. In the game control process, the game control means first inputs detection signals of switches such as winning a prize opening switches 513a, 514a, 515a, 516a, specific winning a prize opening switch 532a, count switch 551a, etc., and performs their state determination (switches). Process: Step S331).

  Next, various abnormality diagnosis processing is performed by a self-diagnosis function provided in the pachinko gaming machine, and an alarm is issued if necessary according to the result (error processing: step S332).

  Next, a process of updating the count value of each counter for generating each random number for determination used for game control is performed (step S333). In this embodiment, there are a random number for normal symbol determination and a random number for determination per determination symbol as random numbers for determination.

  The game control means further performs a process of updating the count value of the counter for generating the display random number and the initial value random number (steps S334 and S335). In this embodiment, there is a random number for determining a stop symbol of the determination symbol in the variable display device 512 as the display random number, and the random number for random 5 initial value shown in FIG. There is a random number for determining the initial value of the random number for determination per determination symbol not shown in FIG. In this embodiment, a big hit determination random number or the like is not used.

  Further, the game control means performs process processing (step S336). In the process control, corresponding processing is selected and executed according to a process flag for controlling the pachinko gaming machine in a predetermined order according to the gaming state. The value of the process flag is updated during each process according to the gaming state.

  Further, normal symbol process processing is performed (step S337). In the normal symbol process, the corresponding process is selected and executed according to the normal symbol process flag for controlling the display state of the normal symbol display device 510 in a predetermined order. The value of the normal symbol process flag is updated during each process according to the gaming state. The normal symbol process can be executed in the same manner as in the first embodiment (see FIG. 19).

  Next, the game control means performs a process of setting the display control command in a predetermined area of the RAM 55 and transmitting the display control command (command control process: step S338). Furthermore, the game control means performs information output processing for outputting data such as jackpot information and start information supplied to the hall management computer, for example (step S339).

  In addition, the game control means outputs a drive command to the solenoid when a predetermined condition is satisfied (step S340). Further, a signal instructing driving of each motor is given to each motor (step S341).

  Then, the game control means executes a prize ball process for setting the number of prize balls based on detection signals from the prize opening switches 513a, 514a, 515a, 516a, the count switch 551a, and the like (step S342). Specifically, a payout control command indicating the number of prize balls is output to the payout control board in response to winning detection based on the fact that the winning opening switches 513a, 514a, 515a, 516a, the count switch 551a, etc. are turned on. The payout control CPU mounted on the payout control board drives the ball payout device in accordance with a payout control command indicating the number of winning balls. Thereafter, the contents of the register are restored (step S343), and the interrupt permission state is set (step S344).

  With the above control, in this embodiment, the game control process is started every 2 ms. In this embodiment, the game control process is executed by the timer interrupt process. However, in the timer interrupt process, for example, only a flag indicating that an interrupt has occurred is set, and the game control process is performed by the main process. May be executed.

  FIG. 38 shows a random number for determination per decision symbol used in this embodiment (random 8: one of random numbers for determination) and a random 8 initial value determination random number (random 9) for determining an initial value of random 8 It is explanatory drawing which shows. If the random 8 value extracted at a predetermined timing matches the hit determination value, it is determined that the hit is based on the determination symbol. The CPU 56 determines whether or not the random 8 value matches the hit determination value in the process process (step S336). Further, as described above, in this embodiment, random 5 (normal random number for determination per symbol) and random 5 initial value determining random number are also used as determination random numbers.

  FIG. 39 is a flowchart showing an example of the determination random number update process (step S333) executed in the game control process shown in FIG. In the determination random number update process, the game control means increments the value of the counter for generating random 5 (normal determination random number per symbol) by 1 (step S401). When the value of the counter for generating random 5 is equal to or greater than (maximum value + 1) (step S402), the count value is returned to 3 (step S403). In this embodiment, (maximum value + 1) is 14.

  Then, the game control means checks whether or not the value of the counter for generating random 5 matches the value stored in the random 5 initial value buffer as the initial value (step S404). If they do not match, the count value remains unchanged. If they match, random 7 (random 5 initial value determination random number) is extracted (step S405). That is, the count value of the counter for generating random 7 is input. Then, the extracted value is stored as an initial value in an initial value buffer for random 5 (step S406), and the extracted value is set in a counter for generating random 5 (step S407). Therefore, at this time, the initial value of the counter for generating random 5 is changed. When the game machine is turned on, “3” is set as an initial value to the counter for generating random 5, but if the value of random 5 is stored in the backup RAM, the power is turned on. Sometimes restored to saved value. A random 5 initial value buffer is also formed in the backup RAM.

  Furthermore, the game control means increments the value of the counter for generating random 8 (random number for determination per determination symbol) by 1 (step S421). When the value of the counter for generating the random 8 is equal to or greater than (maximum value + 1) (step S422), the count value is returned to 0 (step S423). In this embodiment, (maximum value + 1) is 19.

  Then, the game control means checks whether or not the value of the counter for generating the random 8 matches the value stored in the random 8 initial value buffer as the initial value (step S424). If they do not match, the count value remains unchanged. If they match, random 9 (random 8 initial value determination random number) is extracted (step S425). That is, the count value of the counter for generating random 9 is input. The extracted value is saved as an initial value in the initial value buffer for random 8 (step S426), and the extracted value is set in a counter for generating random 8 (step S427). Therefore, at this time, the initial value of the counter for generating random 8 is changed. When the game machine is turned on, “0” is set as an initial value in the counter for generating random 8; however, if the value of random 8 is stored in the backup RAM, the power is turned on. Sometimes restored to saved value. A random 8 initial value buffer is also formed in the backup RAM.

  FIG. 40 is executed once in the game control process shown in FIG. 37 (step S325), and the remaining surplus time in the main process shown in FIG. It is a flowchart showing an example of an initial value random number update process (step S18) that is repeatedly executed at a time until the occurrence of the error. In the initial value random number update process, the game control means increments the value of the counter for generating random 7 (random 5 initial value setting random number) (step S431). When the value of the counter for generating random 7 is equal to or greater than (maximum value + 1) (step S432), the count value is returned to 3 (step S433). In this embodiment, (maximum value + 1) is 14.

  Further, the game control means increments the value of the counter for generating random 9 (random 8 initial value setting random number) (step S434). If the value of the counter for generating random 9 is equal to or greater than (maximum value + 1) (step S435), the count value is returned to 0 (step S436). In this embodiment, (maximum value + 1) is 19.

  Also in this embodiment, by executing the processing shown in FIG. 39 and FIG. 40, the random 5 initial for determining whether or not the symbol stopped and displayed on the normal symbol display device 510 is a winning symbol is determined. The value is random. For example, the value of the counter for generating random 5 (ordinary random number per symbol) illustrated in FIG. 25 is also applicable to this embodiment, and as indicated by an asterisk in FIG. There is no regularity at the timing when the count value for judgment per normal symbol becomes the hit judgment value, and it becomes random.

  As a result, even if the illegal board is connected to the main board and the count value update timing for determining the normal symbol per unit is recognized based on the signal output from the main board, the count value for determining the normal symbol per unit is changed to the hit determination value. It is difficult to send an illegal start winning signal to the main board at the timing.

  In this embodiment, when the display result of the normal symbol display device 510 is a winning symbol, the ordinary electric accessory 550 is activated and the specific winning opening 532 is opened. Further, the game ball that the game ball has won in the specific winning port 532 is detected by the specific winning port switch 532a and enters the sorting member 535. Thereafter, when the special device operation determination symbol gate 541 in the guide unit 540 passes, the determination symbol starts variable display in the variable display device 512. Further, if the variable display result (stop symbol) of the determination symbol on the variable display device 512 is a hit symbol, a hit occurs, and the game ball stored at the detection position of the operation determination symbol gate 541 is activated by the guidance device. Guided to the area. And when it is detected by a sensor provided in the special device operating area, a right is generated. Therefore, when the display result of the normal symbol display device 510 is a winning symbol, a right generation state can occur. Therefore, the cheating person wants to generate more hit symbols as the display result of the normal symbol display device 510 and tries to cheat so that the stop symbol of the normal symbol display device 510 becomes the hit symbol. However, in this embodiment, such illegal acts can be effectively prevented.

  In this embodiment, the initial value of the random number for determination per determination symbol is further controlled to be random. FIG. 41 is an explanatory diagram showing an example of a counter value for generating random 8 (determination random number per determination symbol) that is changed by the processing shown in FIGS. 39 and 40. In this example, the first value of random 8 is zero. Since “0” is initially stored as an initial value, the count value advances to “18”, and when the count value is incremented by 1 and returns to 0 (steps S421, S422, and S423), the process of step S424 is performed. It is detected that the count value matches the initial value. Then, random 9 (random 8 initial value determination random number) is extracted in the process of step S425. This time point is indicated by A in FIG.

  Here, it is assumed that the count value of the counter for generating the random 9 at that time is “3”. Then, “3” is extracted as random 9 and the value is stored (step S426), and the value is set in the counter for generating random 8. Therefore, from this point, the counter for generating the random 8 advances from the initial value “3”.

  When the value of the counter for generating random 8 advances to “3”, it is detected in step S424 that the count value matches the initial value. Then, random 9 is extracted by the process of step S425. This time point is indicated by B in FIG. Assume that the count value of the counter for generating the random 9 at that time is “11”. Then, “11” is extracted as the random 9 and the value is stored (step S426), and the value is set in the counter for generating the random 8. Therefore, from this point, the counter for generating the random number 8 advances from the initial value “11”.

  Then, when the value of the counter for generating the random 8 advances to “11”, it is detected in step S424 that the count value matches the initial value. Then, random 9 is extracted by the process of step S425. This time point is indicated by C in FIG. Assume that the count value of the counter for generating random 9 at that time is “p”. Then, “p” is extracted as the random 9 and the value is stored (step S426), and the value is set in the counter for generating the random 8. Therefore, from this point, the counter for generating the random 8 advances from the initial value “p”. In FIG. 41, an asterisk (☆) indicates a position where the count value is “11 (determined value per determination symbol)”.

  As described above, every time the value of the counter for generating random 8 makes one round (19 counts), a new initial value is set as the count value, and thereafter the counter advances from that value. The counter for determining the initial value of the counter for generating random 8 (determination counter per determination symbol) (counter for generating random 9) is the remainder of the game control process executed by the CPU 56 in the game control means The time is counted up (time from the end of the game control process until the next 2 ms timer interrupt is generated). The extra time varies depending on the progress of the game, and is a random period. As a result, since the generated random 9 value is also a random value, the initial value of the determination symbol per determination symbol also changes randomly.

  That is, every time the value of the counter for determination per determination symbol makes one round, the counter starts to increment from a random initial value. Then, even if the illegal board is connected to the main board and the determination value update timing per determination symbol is recognized based on the signal output from the main board, the determination count value per determination symbol becomes the hit determination value. It is difficult to send an incorrect start winning signal to the main board for the purpose of timing. This is because, according to this embodiment, as indicated by a star in FIG. 41, the timing at which the count value for determination per determination symbol becomes the hit determination value has no regularity and is random.

Embodiment 5. FIG.
Next, a case where the present invention is applied to a general electric machine of a pachinko gaming machine will be described. FIG. 42 is an explanatory diagram showing an example of a game area of a general electric machine. In the example shown in FIG. 42, a first normal symbol display 609 having three display areas for performing variable display of normal symbols is installed in the approximate center of the game area 607. The game area 607 is provided with winning ports 611, 612, 613, and 614, and electric accessories (variable winning ball devices) 615, 622, 623, and 624. The variable winning ball device 615 is provided with a second normal symbol display 610 for variably displaying normal symbols. The variable winning ball devices 622 and 623 are provided with a third normal symbol display 622A and a fourth normal symbol display 623A for variably displaying normal symbols. Furthermore, a gate 621 is provided below the first normal symbol display 609, and a gate 618 is provided below the variable winning ball apparatus 615.

  The game balls that have won the winning ports 611, 612, 613, 614 are detected by the winning port switches 611a, 612a, 613a, 614a. The game balls that have won the variable winning ball devices 615, 622, 623, 624 are detected by the winning port switches 615a, 622a, 623a, 624a. The game balls that have passed through the gates 621 and 618 are detected by the gate switches 621a and 618a.

  When it is detected that the game ball has passed through the gate 621, a variable display of the symbol is performed on the first normal symbol display 609, and if the display result is a winning symbol, the winning symbol is determined. 622 is opened for a predetermined period (for example, 5.9 seconds). However, if a predetermined number (for example, five) of game balls wins before the predetermined period elapses, the variable winning ball device 622 is closed. In addition, when a game ball wins the variable winning ball apparatus 622, the third normal symbol display 622A displays a variable symbol, and one or a plurality of symbols (a plurality of symbols having a predetermined symbol stopped) are displayed. When it is determined that any of them is determined, the variable winning ball apparatus 623 is opened for a predetermined period (for example, 5.9 seconds). However, when a predetermined number (for example, seven) of game balls wins before the predetermined period elapses, the variable winning ball device 623 is closed.

  In addition, when a game ball is won in the variable winning ball apparatus 623, a variable display of symbols is performed on the fourth normal symbol display 623A, and the stopped symbol matches one or more predetermined symbols. The variable winning ball device 624 is in an open state for a predetermined period (for example, 4.3 seconds). Note that a winning memory (for example, a maximum of 4) is provided for winning that starts variable display of the third normal symbol display 622A and the fourth normal symbol display 623A, and the number of winning memories is 1 when the variation of the symbol cannot be started. When the number is increased and the state of the change of the symbols can be started, the change of the symbols in the third normal symbol display 622A and the fourth normal symbol display 623A is started and the winning memory is reduced by one.

  Further, when the game ball passes through the gate 618, the second normal symbol display 610 starts variable display of the normal symbol. Then, when the stop symbol matches one or more predetermined winning symbols, the variable winning ball device 615 is opened for a predetermined period. However, if a predetermined number of game balls win before the predetermined period elapses, the variable winning ball device 615 is closed.

  As described above, in this embodiment, the gaming machine is provided with the first to fourth ordinary symbol displays 609, 610, 622A, 623A, and the four variable winning ball devices 610, 622, 623, 624. Is provided. The display result of the first normal symbol display 609 is related to the state change of the variable winning ball device 622 (from the closed state to the open state), and the winning of the game ball to the variable winning ball device 622 is displayed in the third normal symbol display. This is a condition for starting the variable display of the normal symbol of the device 623A. Further, the display result of the third normal symbol display 623A is related to the state change of the variable winning ball apparatus 623. Therefore, for example, the variable winning ball device 623 establishes the variable display start condition in the normal symbol display 623A corresponding to the variable winning ball device 624 different from the variable winning ball device 623 by winning the game ball. Here, the “ordinary symbol display device corresponding to the variable winning ball device” refers to a normal symbol display device on which variable display related to the state change of the variable winning ball device is performed.

  Also in such a gaming machine, whether the game control means mounted on the game control board (main board) uses the stop symbols of the first to fourth normal symbol displays 609, 610, 622A, 623A as winning symbols. Whether or not the lottery can be performed can be executed based on the count value of the counter that periodically updates the count value and returns to the initial value when the maximum value is exceeded. For example, counters for generating random 5-1 to 5-4 are used, and random values 5-1 to 5-4 based on the count values of these counters and determination values illustrated in FIG. 43 are used. A lottery can be performed. In this case, the fraudster desires to generate more winning symbols as the display results of the first to fourth normal symbol indicators 609, 610, 622A, and 623A, and the first to fourth ordinary symbol indicators 609. , 610, 622A, and 623A may be fraudulent (the act of sending a fraudulent signal to the main board aiming at the timing when the count value of the counter matches the winning value). .

  Therefore, in this embodiment as well, in the same manner as in the first to fourth embodiments described above, the game control means uses a random number (random 7-1 to determine the initial value of random 5-1 to 5-4. 7-4) is prepared, and when each of the random 5-1 to 5-4 values makes one round, the corresponding random 7-1 to 7-4 values are extracted, and the extracted random 7-1 to 7-4 Is set to the initial value of the counter for generating random numbers 5-1 to 5-4. Each counter for generating random 7-1 to 7-4 is updated within the same range as the counter for generating random 5-1 to 5-4. In the same manner as in the case of Random 7 in -4, the game control process is incremented once by the game control process executed by the CPU 56, and the remaining time of the game control process (after the game control process ends, the 2 ms timer Counts up) Further, the counter for generating the random numbers 5-1 to 5-4 may be counted up once in the game control process as in the case of the random number 5 in the first to fourth embodiments. By doing so, it is possible to prevent the counter update cycle for generating random 5-1 to 5-4 from being synchronized with the counter update cycle for generating random 7-1 to 7-4. The initial value of the counter for generating random 5-1 to 5-4 can be made random. Therefore, the timing at which the random values 5-1 to 5-4 coincide with the hit determination value can be made indefinite.

  As a result, it is possible to prevent the act of illegally hitting the stop symbols of the first to fourth normal symbol indicators 609, 610, 622A, and 623A as a symbol. The counter for generating random 5-2 is updated when a carry of the counter for generating random 5-1 occurs, and the counter for generating random 5-3 is updated with random 5-2. The counter for generating a random 5-4 is updated when a carry of the counter to generate is generated, and the counter for generating a random 5-3 is updated when a carry of the counter is generated. May be.

  Even in this embodiment, if a RAM backed up by a backup power source is provided and the counter value for generating random numbers and the count value of the counter for determining the initial value are stored in the backup RAM, A counter for generating a random number based on the data stored in the backup RAM if the power supply is restored within a predetermined time (backup power backup possible time) after the power supply to the machine is stopped The count value of the counter for determining the initial value can be restored to the state before the power supply is stopped.

  As described above, in each of the above-described embodiments, a normal symbol or the like, which is a condition for opening an electric combination other than the big winning opening (normal electric combination) that can be opened in a specific game state, etc. In a gaming machine equipped with a display device that performs fluctuations (variable display), an initial value of a counter for generating a random number for determining whether or not to decide to make an electric accessory open state Since it is changed randomly, it becomes difficult to aim fraudulently, and illegal acts can be effectively prevented. That is, it is difficult to specify from the outside of the gaming machine the timing at which the numerical value matches a predetermined determination value, even for the numerical value used to determine whether or not the ordinary variable winning device is to be in an advantageous state for the player. can do.

  In the above embodiment, when the count value makes one round, the initial value of the counter is changed based on the initial value random number. However, when the count value makes multiple rounds, the counter value is changed based on the initial value random number. The initial value may be changed. In that case, the number of laps of the count value whose initial value is to be changed may be made variable, or the number of laps may be made random using a random number or the like.

  Further, in each of the above embodiments, the hit determination value is constant, but may be changed. For example, using a random number for switching the hit determination value, the random value is extracted at a predetermined timing, and the hit determination value is switched based on the extracted random number value. In this case, the determination value switching timing may be indefinite. For example, the winning determination value may be switched every time there is a game ball winning at a winning opening (for example, winning holes 29, 30, 33, 39 in the first embodiment).

  Further, in each of the above embodiments, the counter for generating the initial value determination random number is counted up by software, but may be counted up based on a clock signal created by hardware. . In that case, the randomness of the initial value is further improved by significantly increasing the frequency of the clock signal with respect to the counter update period by software.

  Further, in each of the above embodiments, the extraction timing of a random value (for example, random 5) for determining whether or not to win is constant (for example, the gate switch 32a in the first embodiment). At the time of detection), the timing may be shifted. As an amount of shifting the timing, for example, a change amount of the resistance value based on a temperature change can be used.

  Further, in each of the above embodiments, the case where the initial value of the random number for determining the stop symbol of the normal symbol or the determination symbol is randomly changed has been described, but the probability that the hit based on the big hit or the normal symbol will occur is described. In a game machine that can be changed, whether to change the probability is determined using a random number based on the count value of the counter that periodically counts up and returns to the initial value when the count value makes one round In such a case, the initial value of such a counter may be changed randomly.

  In addition, in a gaming machine having a time shortening function that shortens the variation time (variable display period) of special symbols and ordinary symbols, whether or not to shorten the variation time is counted up periodically and the count value is 1. When it is configured to use a random number based on the count value of the counter that returns to the initial value when it circulates, the initial value of such a counter may be changed randomly.

  In addition, it is determined by using a random number based on the count value of the counter that periodically counts up and returns to the initial value when the count value goes around once, as a stop symbol among multiple types of normal symbols. In such a case, the initial value of such a counter may be changed randomly. In addition, the count value of the counter that returns to the initial value when the count value is counted up once and periodically counts up which of the two types of special symbols or regular symbols is the stop symbol. In the case where the determination is made using a random number based on, the initial value of such a counter may be changed randomly.

  In the first embodiment (Embodiment 1), whether or not to reach is determined according to the determined combination of stop symbols, but whether or not to reach is periodically counted.
