Abstract

PROBLEM TO BE SOLVED: To enable make respective control means to surely receive a command from a game control means at all times. SOLUTION: An IC 901 for power source monitoring defines that power interruption is generated when a +30V voltage becomes equal to or lower than a prescribed value and supplies interruption signals to a CPU 56. On other substrates such as a prize ball control substrate 371, the IC 931 for the power source monitoring supplies the interruption signals to the CPU when the +30V voltage becomes equal to or lower than the prescribed value. The voltage of a +30V power source for which the IC 901 for the power source monitoring outputs the signals is set higher than the voltage of the +30V power source for which the IC 931 for the power source monitoring outputs the signals. Thus, when a power supply voltage lowers, NMI interruption is applied to the CPU 56 of a main substrate earlier than the CPU of the other respective substrates and the CPU 56 starts an NMI interruption processing earlier.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine such as a pachinko gaming machine, and more particularly to a game machine in which a game medium is shot by a player's operation and the game medium wins a prize area provided in the game area. A predetermined value is given to the player, and a special game is performed by the entry of the game medium into the specific winning section, and the predetermined game value is given to the player based on the result of the special game being in a predetermined mode. The present invention relates to a gaming machine that can be provided.

[0002]

2. Description of the Related Art 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 winning area such as a winning opening provided in the game area, a predetermined number of prize balls are obtained. Are paid out to players.
Furthermore, a variable display unit capable of changing the display state is provided,
There is a configuration in which a predetermined game value is provided to a player when a display result of the variable display unit has a predetermined specific display mode.

[0003] When the display result of the variable display section for displaying a special symbol is a combination of a predetermined specific display mode, it is usually called a "big hit". In addition, the game value is a right to make the state of the variable prize ball device provided in the game area of the gaming machine advantageous for a player who is easy to win a hit ball, or a right for the player to be in an advantageous state. Or to generate.

[0004] When a big hit occurs, for example, a big winning opening is opened a predetermined number of times, and the state shifts to a big hit game state in which a hit ball is easy to win. Then, in each open period, when a predetermined number (for example, 10) of winning prizes is won, the winning prize opening is closed. The number of opening of the special winning opening is fixed to a predetermined number (for example, 16 rounds). An opening time (for example, 29.5 seconds) is determined for each opening, and if the opening time elapses even if the number of winnings does not reach a predetermined number, the winning opening is closed. If the predetermined condition (for example, winning in the V zone provided in the special winning opening) is not satisfied at the time when the special winning opening is closed, the big hit gaming state ends.

[0005] In addition, among the combinations of display modes other than the "big hit" combination, at a stage where some of the display results of the plurality of variable display portions have not been derived and displayed yet, the display results have already been derived and displayed. The state in which the display mode of the variable display unit that satisfies the display condition that is a combination of the specific display modes is called “reach”. If the display result of the identification information variably displayed on the variable display unit does not satisfy the condition of “reach”, the result is “out” and the variable display state ends. A player plays a game while enjoying how to generate a big hit.

The progress of the game in the gaming machine is controlled by game control means such as a microcomputer. The identification information, the character image, and the background image displayed on the variable display device are controlled by display control means operating according to display control command data from the game control means.
The identification information, the character image, and the background image displayed on the variable display device generally include a display control microcomputer and a video display processor (FIG. 1) that generates image data in accordance with instructions from the microcomputer and transfers the image data to the variable display device side. VDP), and the display control microcomputer has a large program capacity.

Therefore, the microcomputer of the game control means, which has a limited program capacity, cannot control the identification information and the like displayed on the variable display device, and is different from the microcomputer of the game control means for display control. A microcomputer (display control means) is used. Therefore, the game control means for controlling the progress of the game needs to transmit a command for display control to the display control means.

In such a gaming machine, a speaker is provided on the game board, and various sound effects are emitted from the speaker as the game progresses in order to enhance the game effect. Further, a light emitting body such as a lamp or an LED is provided on the game board, and these light emitting bodies are turned on or off as the game progresses in order to enhance the game effect. Generally, sound control for generating a sound effect and timing control of lamp lighting / extinguishing are performed by game control means for controlling the progress of the game. Therefore, it is necessary for the game control means to transmit a command to the sound control means or the lamp control means for actually generating sound or driving the lamp / LED.

In general, a player rents out a game medium via a game machine. In that case, a gaming medium lending mechanism is provided in the gaming machine. Since the progress of the game is controlled by the game control means mounted on the main board, the number of prize balls based on the winning is determined by the game control means and transmitted to the prize ball control board.

As described above, the gaming machine is equipped with various control means in addition to the game control means. Then, the game control means for controlling the progress of the game transmits each command indicating an operation instruction according to the game situation to each control means mounted on each control board.

[0011]

When the power supply to the gaming machine is stopped, the drive voltage (for example, +5 V) for driving each control means gradually decreases. Each control unit generally includes a microcomputer, but the voltage at which each control unit becomes inoperable is different due to variations in elements and the like. When transmitting a command from the game control means to each control means, from the viewpoint of preventing unauthorized signal input to a game control board on which the game control means is mounted, it is configured not to take a response from each control means. I have. Then, for example, even though the game control means has transmitted the command immediately before the power supply to the gaming machine is stopped, the control means on the side receiving the command may have already become inoperable.
In this case, the game control means recognizes that the command has been transmitted, but the control means on the side receiving the command has not received the command. In that case, in general, the driving voltage is lost, the game control means and other control means do not operate, and thereafter, when the power is turned on again, the game is reset, so that there is often no problem.

However, when an unexpected power failure such as a power failure occurs, necessary data is stored in a power supply backup RAM, and the stored data is restored when the power is restored to restart the game. This is a problem when configured. For example, the prize ball control means may store the number of prize balls instructed by the game control means in the backup RAM, and continue paying out prize balls based on the number of prize balls stored when the power is restored after the power is turned off. If configured,
It is conceivable that the prize ball control means did not receive the instruction even though the game control means issued a predetermined number of prize ball payout instructions immediately before the power was turned off. In this case, even if the prize ball control means resumes the prize ball payout based on the memory after the power is restored, a smaller number of prize ball payouts than the number of prize balls that should be paid out are performed. That is, a disadvantage is given to the player.

[0013] In addition to the prize ball control means, other control means may not be able to receive the command even though the game control means has transmitted the command immediately before the power is turned off. If this occurs, the control state may fall into an undesirable state after the power is restored. For example, after the power is restored, there is a possibility that a display state or an utterance state that should not appear originally may occur. Furthermore, even when the power is turned on, despite the game control means sending a command,
If other control means are not ready to receive, there is a possibility that the command may be missed.

An object of the present invention is to provide a gaming machine in which each control means can always reliably receive a command from the game control means.

[0015]

In the lamp control board 35, the CPU 351 for lamp control includes a game effect LED 28a and a game effect lamp 28 defined in accordance with each control command.
b, 28c, the game effect L
A light-on / light-off signal is output to the ED 28a and the game effect lamps 28b and 28c. The light-on / light-off signal is output from the game effect LED 28a and the game effect lamps 28b and 28c.
Is output to The light-on / light-off pattern is stored in a built-in ROM or an external ROM of the lamp control CPU 351.

On the main board 31, the CPU 56 outputs a control command for instructing lighting of a prize ball lamp at the time of a prize ball,
When a ball-out detection sensor installed on the game ball supply path on the back of the game board is turned on, a control command for instructing the ball-out lamp to be turned on is output. In the lamp control board 35, each control command is input to the lamp control CPU 351 via the input buffer circuit 355. Lamp control CPU3
51 is a prize ball lamp 5 according to those control commands.
1 and the ball out lamp 52 are turned on / off.

As the input buffer circuit 355, for example,
74HC244 which is a general-purpose CMOS-IC is used. A low level (GND level) is always applied to the enable terminal of the 74HC244. Therefore, the output level of each buffer is the input level, that is, the main board 31.
Signal level has been determined. Therefore, there is no room for a signal to be transmitted from the lamp control board 35 side to the main board 31 side. For example, even if a circuit in the lamp control board 35 is tampered with, a signal output by the tampering is not transmitted to the main board 31 side. Note that a noise filter may be provided on the input side of the input buffer circuit 355.

In the configuration shown in FIG. 7, a signal line to which a signal may be given from the lamp control board 35 to the main board 31 can be eliminated. That is, the unidirectionality of the signal from the main board 31 to the lamp control board 35 is ensured, and the possibility that the lamp control board 35 influences the game control on the main board 31 is eliminated. As a result, even if, for example, the lamp control board 35 is modified so as to give an illegal signal for causing a big hit to the basic circuit 53 of the main board 31, the illegal signal cannot be transmitted to the main board 31.

Further, on the main board 31, a buffer circuit 62 is provided outside the output ports 575, 576. As the buffer circuit 62, for example, a general-purpose CMO
74HC244 which is S-IC is used. The enable terminal is always given a low level (GND level). According to such a configuration, the main substrate 31 is externally provided.
Is prevented from being input to the main board 31, so that a signal line to which a signal may be given from the lamp control board 35 to the main board 31 can be more reliably eliminated.

In FIG. 7, the lamp control CPU 35 is used.
Signals for instructing the game effect LED 28a, the game effect lamps 28b and 28c, the prize ball lamp 51 and the ball out lamp 52 to be turned on or off are output from the internal output port 1 in practice. -A driver circuit is inserted between the LED and the LED.

FIG. 8 is a block diagram showing components related to the prize ball, such as the components of the prize ball control board 37 and the ball payout device 97. As shown in FIG. 8, the detection signal from the full tank switch 48 is transmitted to the main board 3 via the relay board 71.
1 is input to the I / O port 57. Full tank switch 4
Reference numeral 8 denotes a switch that detects whether the surplus ball tray 4 is full.

The detection signals from the out-of-ball detection switch 167 and the out-of-ball switch 187 (187a, 187b) are transmitted to the main board 3 via the relay board 72 and the relay board 71.
1 is input to the I / O port 57. The out-of-ball detection switch 167 is a switch for detecting a shortage of replenishment balls in the prize ball tank 38, and the out-of-ball switch 187 is a switch for detecting the presence or absence of a prize ball in the prize ball passage.

The CPU 56 of the main board 31 indicates that the detection signal from the ball-out detection switch 167 or the ball-out switch 187 indicates that the ball is out, or that the detection signal from the full-state switch 48 indicates the full state. , A prize ball control command instructing ball lending is sent. When receiving the award ball control command instructing the ball lending prohibition, the award ball control CPU 371 of the award ball control board 37 stops the ball lending process.

Further, the detection signal from the prize ball count switch 301A is also input to the I / O port 57 of the main board 31 via the relay board 72 and the relay board 71. A drive signal from the I / O port 57 of the main board 31 to the winning ball discharging solenoid 127 is supplied to the winning ball discharging solenoid 127 via the relay board 71. The prize ball count switch 301A is provided in the prize ball mechanism portion of the ball payout device 97, and detects an actually paid prize ball.

When a prize is won, the output ports (ports G, H) 577, 578 of the main board 31 are provided on the prize ball control board 37.
, A prize ball control command indicating the number of prize balls is input. The output port 577 outputs 8-bit data, and the output port 578 outputs a 1-bit strobe signal (INT signal). The award ball control command indicating the number of award balls is input to the I / O port 372a via the input buffer circuit 373. The CPU 371 for controlling the prize ball includes an I / O port 37.
A prize ball control command is input via 2a, and the ball payout device 97 is driven according to the prize ball control command to perform a prize ball payout. In this embodiment, the CPU 37 for controlling the prize ball
Reference numeral 1 denotes a one-chip microcomputer having at least a RAM.

Each buffer in the input buffer circuit 373 can pass a signal only in the direction from the main board 31 to the prize ball control board 37. Therefore, there is no room for a signal to be transmitted from the award ball control board 37 side to the main board 31 side. Even if the circuit in the prize ball control board 37 is tampered with, the signal output by the tampering is not transmitted to the main board 31 side. Note that a noise filter may be provided on the input side of the input buffer circuit 373.

On the main board 31, a buffer circuit 68 is provided outside the output ports 577 and 578 for outputting award ball control commands. According to such a configuration, since a signal input from the outside to the inside of the main board 31 is blocked, a signal line to which a signal may be given from the prize ball control board 37 to the main board 31 is more reliably formed. Can be eliminated.

The prize ball controlling CPU 371 outputs a ball lending number signal indicating the number of lending balls to the terminal board 160 and a buzzer driving signal to the buzzer board 75 via the output port 372g. A buzzer is mounted on the buzzer board 75. Further, an error signal is output to the error display LED 374 via the output port 372e.

Further, the input port 3 of the prize ball control board 37
The detection signal of the prize ball count switch 301A and the detection signal of the ball lending count switch 301B are input to 72b via the relay board 72. The ball lending count switch 301B detects a game ball actually lent. The drive signal from the prize ball control board 37 to the payout motor 289 is output from the payout motor 2 in the prize ball mechanism portion of the ball payout device 97 via the output port 372c and the relay board 72.
It is told to 89.

The card unit 50 is provided with a microcomputer for controlling the card unit. Also,
The card unit 50 is provided with a fraction display switch 152, a connection board direction indicator 153, a card insertion indicator lamp 154, and a card insertion slot 155 (see FIG. 1). The balance display board 74 is connected to a frequency display LED, a ball lending switch, and a return switch provided near the hit ball supply tray 3.

From the balance display board 74 to the card unit 50
In response to the player's operation, a ball lending switch signal and a return switch signal are provided via the prize ball control board 37. In addition, the balance display board 74 is provided from the card unit 50.
, A card balance display signal indicating the balance of the prepaid card and a ball lending possible display signal are given via the prize ball control board 37. Between the card unit 50 and the prize ball control board 37, a unit operation signal (BRDY signal), a ball lending request signal (BRQ signal), a ball lending completion signal (EXS signal)
A pachinko machine operation signal (PRDY signal) is exchanged via the I / O port 372f.

When the power of the pachinko gaming machine 1 is turned on,
The prize ball control CPU 371 of the prize ball control board 37 outputs a PRDY signal to the card unit 50. When a card is accepted in the card unit 50 and the ball lending switch is operated to input a ball lending switch signal, the microcomputer for controlling the card unit outputs a BRDY signal to the prize ball control board 37. When a predetermined delay time elapses from this point, the microcomputer for controlling the card unit outputs a BRQ signal to the prize ball control board 37. The CPU 37 for controlling the prize ball on the prize ball control board 37
1 drives the payout motor 289 and pays out a predetermined number of lending balls to the player. Then, when the payout is completed, the prize ball controlling CPU 371 outputs an EXS signal to the card unit 50.

As described above, all signals from the card unit 50 are input to the prize ball control board 37. Therefore, regarding the ball lending control, the card unit 5
No signal is input from 0 to the main board 31, and there is no room for a signal to be incorrectly input from the card unit 50 side to the basic circuit 53 of the main board 31. Although the main board 31 and the prize ball control board 37 are provided with a solenoid and a driver circuit for driving a motor or a lamp, these circuits are omitted in FIG.

In this embodiment, at least the main substrate 3
At 1, a part of the RAM is backed up by a power supply. That is, even if the power supply to the gaming machine is stopped,
The data in the backup RAM area is saved. Also,
CPU 101 for display control, CPU 701 for voice control, CPU 351 for lamp control, and CPU 371 for award ball control
In this case, a part of the RAM may be configured to be backed up by a power supply.

FIG. 9 shows the main board 31, the display control board 80,
FIG. 3 is a block diagram showing a configuration around a CPU in a voice control board 70, a lamp control board 35, and a prize ball control board 37. In this example, the main board 31 and the CPU for controlling the prize ball
At 371, a part of the CPU built-in RAM is backed up by connecting a backup power supply to the backup terminal.

As shown in FIG. 9, on the main substrate 31,
The power supply monitoring IC 901 introduces a voltage of +30 V,
By monitoring the 0V voltage, the occurrence of power interruption is detected. Specifically, the voltage of +30 V is a predetermined value (for example, +30 V).
90% of V) or less
An interrupt signal is given to the CPU 56. In the CPU 56, this interrupt is input to a non-maskable interrupt (INT) terminal. The signal input to the NMI terminal is also input to an input port built in the CPU 56.

The predetermined value for the power supply monitoring IC 901 to detect the power supply cutoff is lower than the normal voltage.
Is a voltage that can operate for a while. Further, since the power supply monitoring IC 901 is configured to monitor a voltage higher than the voltage required by the CPU 56 (+5 V in this example) and immediately after conversion from AC to DC, the CPU 56 is required. It is possible to extend the monitoring range with respect to the voltage. Therefore, more precise monitoring can be performed. Further, when +30 V is used as the monitoring voltage, the voltage supplied to various switches of the gaming machine is +1.
Since it is 2 V, prevention of erroneous switch-on detection at the moment of a power interruption can be expected. That is, by monitoring the voltage of the +30 V power supply, it is possible to detect a decrease in the voltage of +12 V generated after the generation of +30 V before the voltage starts to drop. Therefore, when the voltage of the + 12V power supply decreases, the switch output comes to the on state. However, if the + 30V power supply voltage that drops faster than + 12V is monitored and the power cutoff is recognized, the power supply is turned on before the switch output turns on. It is possible to enter a state of waiting for restoration and to enter a state where the switch output is not detected.

In the prize ball control board 371, the power supply monitoring IC 931 detects the occurrence of power interruption by introducing a + 30V voltage and monitoring the + 30V voltage. Specifically, a predetermined value (for example, + 3V) in which the +30 V voltage is lower than the voltage at the time of detection by the power supply monitoring IC 901 described above.
If the voltage falls below 80% of 0 V), it is determined that the power is cut off, and an interrupt signal is given to the CPU 371 for controlling the prize ball.
In the winning ball control CPU 371, this interrupt is input to a non-maskable interrupt (INT) terminal. Also,
The signal input to the NMI terminal is the CPU 37 for controlling the prize ball.
1 is also input to the built-in input port.

Note that, in the configuration shown in FIG.
It is desirable that the NMI interrupt signal input to U56 be transmitted through a switch input circuit for inputting detection signals of various switches. In this case, the switch input circuit may be backed up by the power supply. In addition, the voice control board 70, the lamp control board 35, and the display control board 80 are also equipped with the same power supply monitoring IC 931 as +30.
When the V voltage falls below a predetermined value, a signal is given to each CPU.

In the configuration shown in FIG. 9, the voltage of the +30 V power supply at which power supply monitoring IC 901 outputs a signal is set higher than the voltage of the +30 V power supply at which power supply monitoring IC 931 outputs a signal. Have been. Generally, the power supply monitoring IC can set a voltage level at which a signal is output, and such a setting is possible. Therefore, when the power supply voltage decreases, the CPU 56 of the main board receives an NMI interrupt earlier than the CPUs of the other boards, and the CPU 56 starts the NMI interrupt processing earlier.

NMI executed by CPU 56 of main board 31
In the process, as will be described later, only the data saving process when the power is turned off is performed, and each control board (in this example, the display control board 80, the voice control board 70, the lamp control board 35, and the prize ball control board 37) is used. Is not executed. At the time when the CPU 56 starts the NMI process,
Microcomputers in other control means (in this example, display control CPU 101, audio control CPU 70
1. CPU 351 for lamp control and CPU for award ball control
371) is still working. Therefore, the CPU 56
If the command sending process has been performed immediately before the start of the MI process, the sent command is reliably received by each control means.

Further, the reset IC 6 is provided on the main board 31.
An initial reset circuit 65 including 51 is mounted. When detecting that +5 V rises when the power is turned on, the initial reset circuit 65 outputs a signal indicating reset release after a predetermined time (time determined by an external resistance value and a capacitor capacity). Further, the display control board 80, the audio control board 70, the lamp control board 35, and the prize ball control board 37
Also has a similar initial reset circuit. However, in FIG. 9, the reset IC in the prize ball control board 37 is used.
Only the initial reset circuit including 380 is shown.

In the configuration shown in FIG. 9, the resistance value and the capacitance of the resistor and the capacitor in the initial reset circuit 65 of the main board 31 are the same as those of the resistor and the capacitor externally connected to the reset IC 380 of the other control board. Equal to resistance and capacitance. That is, they have the same configuration. Therefore, when the power of the gaming machine is turned on, the reset signals from the reset ICs 651 and 380 rise at the same time.

In the main board 31, the initial reset circuit 6
5 is input to the reset terminal of the CPU 56 via the delay circuit 655. Therefore, when the power is turned on, the CPU 56 of the main board 31 starts up later than the CPUs of the other boards. The output of the delay circuit 655 is 2
Output port 57 via two gate circuits 656 and 657
0 is input to the reset terminal. Output port 570
Is a port for sending commands to other boards,
When the reset signal indicates the reset release state, the state becomes an information output enabled state. Note that the output port 570 is provided in FIGS.
Correspond to the output ports 571 to 578 shown in FIG.

FIG. 10 is a block diagram showing an example of the configuration of the power supply board 910. The power supply board 910 includes a main board 31,
The display control board 80, the voice control board 70, the lamp control board 35, and the control board such as the prize ball control board 37 are installed independently of each other, and generate voltages used by each control board and mechanical components in the gaming machine. In this example, AC24V, DC + 3
Generates 0V, + 21V DC, + 12V DC and + 5V DC. A capacitor 9 serving as a backup power supply
16 is charged from DC + 5V, that is, a power supply line for driving an IC or the like on each substrate.

The transformer 911 converts an AC voltage from an AC power supply to 24V. AC 24V voltage is applied to connector 9
15 is output. Further, the rectifier circuit 912 includes an AC24
A DC voltage of +30 V is generated from V and output to the DC-DC converter 913 and the connector 915. DC-D
The C converter 913 has + 21V, + 12V and + 5V.
V is generated and output to the connector 915. Connector 91
Reference numeral 5 is connected to, for example, a relay board, from which power of a voltage required for each control board and mechanical components is supplied.

+5 V from DC-DC converter 913
The line branches to form a backup + 5V line. A large-capacity capacitor 916 is connected between the backup + 5V line and the ground level. The capacitor 916 serves as a backup power supply for the backup RAM area in each control board when power supply to the gaming machine is cut off. Further, a diode 917 for preventing backflow is inserted between the + 5V line and the backup + 5V line.

Note that a battery that can be charged from a +5 V power supply may be used as a backup power supply. In the case of using a battery, a rechargeable battery is used which runs out of capacity when power is not supplied from a + 5V power supply for a predetermined time.

Next, the operation of the gaming machine will be described. When the power of the gaming machine is turned on, the capacitor is charged via the resistor in the initial reset circuit 65 of the main board 31 shown in FIG. Therefore, the potential of the capacitor increases. When the potential of the capacitor exceeds a predetermined value, the reset IC 651 changes the output level from a low level to a high level, as shown in FIG. The delay circuit 655 delays the output of the reset IC 651 and
It is supplied to the PU 56 as a reset signal. Therefore, CP
U56 has an initial reset circuit 6 as shown in FIG.
The reset signal at a low level is applied until a time point later than the time point when the output signal of No. 5 rises, and thereafter, the reset signal rises to a high level. That is, the CP
The reset of U56 is released.

The amount of delay in the delay circuit 655 is
For example, the amount is set so that a command is not transmitted from the game control means before the CPU of each control board has completed execution of the initialization program.

In each of the control boards other than the main board 31, no delay circuit is provided, so that the reset signal input to each CPU rises earlier. That is, each CPU is in an operable state earlier than the CPU 56 of the main board 31. Therefore, the CPU 56 of the main board 31
Does not occur in which the control means cannot receive the command transmitted by the control means.

FIG. 12 shows the CPU 56 on the main board 31.
It is a flow chart which shows the game control processing of. FIG.
FIG. 1A shows a main process executed by the CPU 56, and FIG.
2 (B) shows an interruption process. When the reset at the time of power-on is released, the CPU 56 first sets a built-in clock monitor register to a clock monitor enable state in order to enable clock monitor control (step S1). Clock monitor control means that when detecting a drop or stop of an input clock signal, the CPU
This is a control for automatically generating a reset inside 56.
Next, the CPU 56 performs an initialization process (step S
2). In the initialization process, after a predetermined period (for example, 2 m
After s), the timer is set so that the timer is interrupted. Thereafter, the process of updating the display random number such as the random number for determining the type of the stop symbol is repeatedly executed (step S).
17).

The processing shown in FIG.
6 is activated by an internal timer interrupt. In the interrupt processing, the CPU 56 firstly sets a predetermined period (for example, 2 ms).
After that, a timer setting process is performed so that the timer is again interrupted (step S20).

Next, after performing processing for setting a display control command sent to the display control board 80 to a predetermined area of the RAM 55 (display control data setting processing: step S
4) A process for outputting a display control command is performed (display control data output process: step S5).

Next, processing for outputting the contents of the storage area for various output data to each output port is performed (data output processing: step S6). Further, an output data setting process for setting output data such as jackpot information, start information, and probability variation information output to the hall management computer in the storage area is performed (step S8). Further, various abnormality diagnosis processes are performed by a self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error process: step S9).

Next, a process of updating each counter indicating each random number for determination such as a random number for big hit determination used in game control is performed (step S10).

Next, the CPU 56 performs a special symbol process (step S11). In the special symbol process control, a corresponding process is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to a gaming state. Then, the value of the special symbol process flag is updated during each processing according to the gaming state. Further, a normal symbol process is performed (step S12). In normal symbol processing, 7 segments L
A corresponding process is selected and executed according to a normal symbol process flag for controlling the variable display 10 by the ED in a predetermined order. Then, the value of the normal symbol process flag is updated during each process according to the gaming state.

Further, the CPU 56 includes a switch circuit 58
, The state of the gate sensor 12, the starting port sensor 17, and the count sensor 23 are input, and it is determined whether or not there is a prize for each prize port or prize device (switch processing: step S13). The CPU 56 further performs a process of updating a display random number such as a random number for determining the type of stop symbol (step S15).

Further, the CPU 56 performs signal processing between the CPU 56 and the award ball control board 37 (step S16). That is,
When a predetermined condition is satisfied, a prize ball control command is output to the prize ball control board 37. The prize ball control CPU mounted on the prize ball control board 37 drives the ball payout device 97 according to the prize ball control command.

FIG. 13 is a flowchart showing the NMI interrupt processing of the CPU 56. As described above, when the power supply monitoring IC 901 detects a drop in the power supply voltage, the CPU 5
6 receives an NMI interrupt. Further, as shown in FIG. 9, the output of the power supply monitoring IC 901 is introduced to the input port.

In the NMI interrupt process based on the drop in the power supply voltage, the CPU 56 first transfers the contents of the register to the backup RAM (step S31). Then N
The MI flag is set (step S32). The NMI flag is an internal flag indicating that an interrupt has occurred due to a drop in power supply voltage. The NMI flag is set in the backup RAM area. The CPU 56 further disables the RAM access (step S3).
3) Continue to monitor the level of the input port to which the output of the power monitoring IC 901 is introduced (step S34).
In this state, the power supply voltage further decreases, and finally,
The operation of the CPU 56 stops.

However, when the level of the input port has returned to the normal level, the CPU 56 enables the RAM access (step S35), and stores the register value stored in the backup RAM into the original register. It is returned (step S36). Then, the NMI flag is reset (step S37), and the address returns to the address where the NMI interrupt was interrupted.

As described above, when the CPU 56 detects that the power supply voltage has returned to normal, it returns the register state to the original state and returns to the address where the NMI interrupt was interrupted. Therefore, control can be returned to a normal state even when noise or the like is present on the NMI line.

As shown in FIG. 11, the main substrate 31
When the power supply monitoring IC 901 detects the voltage drop of +30 V, the power supply monitoring IC 931 on another control board is used.
Is earlier than the time point when the voltage drop of +30 V is detected. That is, when the CPU 56 of the main board 31 starts the NMI process, the other CPUs are still operating normally. Then, in the NMI process of the CPU 56, since a loop is performed in step S34, transmission of a new command is not started. Therefore, when the power is turned off, the other CPUs do not receive a command from the main board 31. It should be noted that NMI can be used for other CPUs.
When the processing is performed, the execution is started with a delay as shown in FIG.

FIG. 14 is a flowchart showing an example of the initialization process (step S2) in the main process shown in FIG. When the power supply to the gaming machine is resumed,
A reset signal is input from the initial reset circuit 65 to the CPU 56. The CPU 56 starts the main process in response to the initial reset signal. In the system check process, first, the CPU 56 checks whether or not the NMI flag is set (step S42).

Here, if the RAM access is not automatically enabled when the reset is applied, C
The PU 56 sets the RAM access permission state.

If the NMI flag is not set,
Clear all registers and RAM area (step S
46), necessary initial values are set (step S47).
Then, a power-on screen display command transmission request is set (step S48), the stack pointer is initialized (step S49), and the initialization processing ends.

When the power-on screen display command transmission request is set, the power-on screen display command is transmitted to the display control board 80 by, for example, the display control data output process (step S5) shown in FIG. Is done. When the display control CPU 101 of the display control board 80 receives the power-on screen display command, the display control CPU 101
Next, a screen that is determined in advance as a screen displayed when the power is turned on is displayed.

When it is confirmed at step S42 that the NMI flag is set, the CPU 56 restores the register value stored in the backup RAM to the original register (step S43). Then, the NMI flag is reset (step S44), and an error screen display command transmission request is set (step S45).

When an error screen display command transmission request is set, an error screen display command is transmitted to the display control board 80 by, for example, display control data output processing (step S5). Upon receiving the power-on screen display command, the display control CPU 101 of the display control board 80 displays a predetermined error screen on the variable display unit 9.

Then, the CPU 56 jumps there with the value of the stack area indicated by the stack pointer as the jump destination. Since the stack pointer is one of the registers, the stack pointer has been restored to the value at the time of power-off by the processing in step S43. Also, in this embodiment,
The stack area is formed in the backup RAM area. That is, it is preserved even when the power is turned off. Therefore, the control state returns to the state when the power was turned off.

For example, it is assumed that the display control CPU 101 on the display control board 80 is performing symbol variation display on the variable display section 9 when the power is turned off. Then, when the power is restored, the display control CPU 101 receives the error screen display command, and displays an error screen on the variable display unit 9. On the other hand, the CPU 56 of the main board 31 returns to the state when the power is turned off, that is, the gaming state in which the special symbol is changing. Then, when the gaming state in which the special symbol is changed ends, a command indicating a symbol stop or a command indicating a big hit display is transmitted. At this stage, the display control CPU 101 can stop the error display and continue the subsequent display control.

As described above, the CPU 56 returns to N
If the MI flag has been set, data recovery processing is performed, and if the NMI flag has not been set, normal initialization processing (steps S46 and S47) is performed. And
In the data restoration processing, the restoration processing of the saved register and the reset processing of the NMI flag are performed. Also,
Since the return to the return address stored in the stack area in the RAM area where the power is backed up is returned, the game control means can return to the game state when the power is turned off.

In the above embodiment, the main substrate 31
The resistance value and the capacitance of the resistor and the capacitor in the initial reset circuit 65 are set equal to the resistance value and the capacitance of the resistor and the capacitor externally attached to the reset IC 380 on the other control board. However, the capacity of the capacitor in the initial reset circuit 65 may be larger than the capacity of the capacitor in another control board. In such a configuration, the rising point of the reset signal from the reset IC 651 of the initial reset circuit 65 is determined by the reset I
This is later than the rising point of the reset signal from C380. Therefore, even if the delay circuit 655 is eliminated and the output of the initial reset circuit 65 is directly supplied to the CPU 56, the CPU 56 of the main board 31
It can be made to stand up later than U.

The CPU 56 of the main board 31 may execute a predetermined security check program prior to the game control program after the reset is released. If it takes a certain amount of time to execute the security check program, it is possible to use the time to quickly release the reset of each CPU on another control board when the power is turned on. FIG. 15 is a block diagram showing another embodiment based on such a concept.

In this case, the delay circuit 655 is not provided on the main board 31, and the output of the initial reset circuit 65 is directly connected to the reset input terminal of the CPU 56. Then, the resistance value and the capacitance of the resistor and the capacitor in the initial reset circuit 65 of the main board 31 are set to values equal to the resistance value and the capacitance of the resistor and the capacitor externally attached to the reset IC 380 of the other control board. However, if the CPUs of the other control boards start up and complete the execution of the initialization program by the time the CPU 56 of the main board 31 completes the execution of the security check program, the resistance values of the capacitors of the other control boards and The capacitance does not have to be equal to the resistance value and the capacitance of the capacitor of the main substrate 31.

Therefore, as shown in FIG.
Of the CPU 56 and the CPUs of the other control boards are released almost simultaneously. When the reset is released, the CPU 56 first executes the security check program. While the security check program is being executed, commands for other control boards are not output from the CPU 56. If it takes a long time to execute the security check program,
Each CPU of the other control boards has finished executing the initialization program. Therefore, it is in a state of waiting for a command.

In this embodiment, as shown in FIG. 16, the time when the execution of the security check program is completed is a substantial timing for releasing the reset of the CPU 56. Therefore, also in this embodiment, after the power of the gaming machine is turned on, the reset release timing of each CPU in each control means is substantially earlier than the reset release timing of the CPU 56 in the game control means. Therefore, a situation does not occur in which a command is sent from the game control unit before the execution of the initialization program in each control unit is completed, and each control unit fails to receive command data.

As described above, in each of the above embodiments,
When the power is turned on, the CPU 56 of the main board 31 rises later than each CPU of the other control means, and when the power is turned off, the CPU 56 of the main board 31 falls earlier than each CPU of the other control means. It is possible to eliminate the possibility that each CPU of the other control means cannot receive a command from the main board 31.

When the power is turned on, the CPU of the main board 31
56 provides a delay time in software before sending commands to other control boards, so that substantially
The CPU 56 of the main board 31 may start up later than each CPU of the other control means.

Hereinafter, the power-off processing in each control means other than the game control means will be described. Here, the award ball control means is taken as an example, but other control means for executing the NMI interrupt processing also perform the same processing. As shown in FIG. 17, the award ball control CPU 371 first sets an NMI flag (step S801). Further, the RAM access is prohibited (step S802), and the power supply monitoring IC 93 is turned off.
The level of the input port to which the output No. 1 is introduced is continuously monitored (step S803).

When the level of the input port returns to the normal level, the award ball control CPU 371 sets the RAM access to a permitted state (step S804), and sets the NMI.
The flag is reset (step S805), and the process returns to the address where the NMI interrupt has occurred.

As described above, the CPU 371 for controlling the prize ball
When it is detected that the power supply voltage has returned to normal, the state of the register is returned to the original state, and the address returns to the address where the NMI interrupt was interrupted. Therefore, control can be returned to a normal state even when noise or the like is present on the NMI line.

FIG. 18 is a flowchart showing the initialization processing in the main processing executed by the award ball control CPU 371. In this case, the award ball control CPU 37 first checks whether or not the NMI flag is set (step S812). If not set, the register and the RAM area are all cleared (step S81).
4), necessary initial values are set (step S815).
Then, the stack pointer is initialized (step S8).
16) End the initialization process.

If it is confirmed in step S812 that the NMI flag is set, the CPU 56 sets the NMI flag
The flag is reset (step S813), and a jump is made to the value of the stack area pointed to by the stack pointer as a jump destination. In this embodiment, it is not necessary to save the value of each general-purpose register in the backup RAM when the power is turned off, but the stack pointer needs to be saved. Since the stack area is formed in the backup RAM area, the CPU 371 for controlling the prize ball controls
By detecting that the NMI flag is set when the power is turned on, it is possible to reliably return to the control state when the power is turned off.

For example, if the award ball flag is set to backup RA
If it is formed in the M area, it is detected that a flag indicating that a prize ball is being set is set, and the CPU 371 for controlling the prize ball.
Can immediately restart the prize ball payout process based on the value of each number counter stored in the backup RAM area.

Even if the flags are not set in the backup RAM area, the number counter is set to the backup RAM area.
If the area is set, the CPU 371 for controlling the prize ball
When the power is restored, the game state memory is read out,
That is, by reading the set value of each number counter, it is possible to detect whether or not there are unpaid prize balls. And
When it is detected that there is an unpaid prize ball, for example, the prize ball payout process can be restarted by setting the prize ball paying flag.

FIG. 19 is a flowchart showing another example of the NMI interrupt process executed by the award ball control CPU 371. In this case, the CPU 371 for controlling the prize ball first
It is checked whether the number of unpaid prize balls or the number of unpaid ball lending is stored (step S821). If there is such a storage, the NMI flag is set (step S8).
22). Further, the RAM access is prohibited (step S823), and the level of the input port to which the output of the power monitoring IC 931 is introduced is continuously monitored (step S803).

When the level of the input port has returned to the normal level, the award ball control CPU 371 sets the RAM access to a permitted state (step S804), and the NMI
The flag is reset (step S805), and the process returns to the address where the NMI interrupt has occurred.

If there is no storage of the number of unpaid prize balls or the number of unpaid ball lending, the RAM access is prohibited (step S823), and the flow shifts to step S803.
According to such control, the preparation for the return of the control state when the power is restored is performed only when the power is cut off in the unpaid state, that is, only when necessary.

In each of the above embodiments, a case has been described in which all the control means other than the game control means perform processing based on an NMI interrupt from the power supply monitoring IC when the power is turned off. The power supply monitoring IC may be mounted only on a necessary control board. Also,
In each of the above embodiments, the NMI interrupt has been exemplified. However, a signal indicating a power supply voltage drop is introduced to an external interrupt (INT) terminal which is not maskable, and an interrupt process based on the interrupt signal of the INT terminal is performed. May go.

Further, similarly to the RAM in the prize ball control means, the RAM in the voice control means, the lamp control means and the display control means may have a power backup portion.

As described above, according to the present invention, when the power supply to the gaming machine is stopped, the gaming control means falls earlier than the gaming machine control means, and the When the power supply is started, the game control means is configured to rise later than the game apparatus control means, so that each game apparatus control means can always reliably receive the command from the game control means. There is.

The game control means and the game device control means, which have received the output signal of the power supply monitoring means, execute the power-off processing in accordance with the signal, and the drop detection voltage of the power supply monitoring means on the game control board is used for the game. When the voltage is higher than the drop detection voltage of the power supply monitoring means in the device control board, the falling point of each control means can be set based on the power supply voltage, so that the game control means can be started up more quickly than the game device control means. Can be lowered.

When the game control means and the game device control means which have received the output signal of the power supply monitoring means are configured to execute the power-off processing in the interruption processing, the processing having the higher priority is performed. Thus, the power-off process is performed reliably.

In the case where the volatile storage means of the game control means is powered on and is configured to hold information necessary for restoring the game state when the power supply of the game machine is restored, an unexpected power failure occurs. Even if the power is cut off due to the above, the power can be restored to the state at the time of power restoration, and there is an effect that the player is not disadvantaged.

In the case where a delay means for delaying the reset signal from the initial reset means and supplying it to the game control means is provided, the initial reset means of the game control board and the initial reset means of the game apparatus control board are the same. It can be configured.

If the capacity of the capacitor for generating the reset signal in the initial reset means of the game control board is larger than the capacity of the capacitor for generating the reset signal in the initial reset means of the gaming machine control board, Since a delay circuit or the like becomes unnecessary, there is an effect that the circuit configuration is simplified.

The game control means executes a predetermined program when the power-on reset is released. When the initial reset means in the game control board and the initial reset means in the game device control board have the same configuration,
There is an effect that the circuit configuration is further simplified.
