[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for supplying power to each section of a gaming machine for paying out prizes such as game balls and medals in accordance with the result of a game.

[0002]

Conventionally, a power supply device of a gaming machine for supplying operating power to each part of the gaming machine has been designed so that when a power supply of the gaming machine to which the gaming machine is being supplied has a power failure, the power supply is simply discharged. There were no defects. That is, a power outage occurs,
When each part of the gaming machine stops functioning, the game is stopped and the prize is not paid out. However, when the power of the gaming machine is restored, the game is resumed and the prize is continued to be paid out.

However, in recent gaming machines, in order to more accurately pay out prizes after the power of the gaming machine is restored, the number of unpaid prizes is always stored regardless of the presence or absence of a power failure. After returning from, the prize that has not been paid out is accurately paid out. As described above, in order to realize a configuration in which the number of unpaid prizes is always stored regardless of the presence or absence of a power outage and the prize unpaid out is accurately paid out after returning from the power outage, the gaming machine must be It was necessary to ensure that the power failure process for shifting to the power failure state was performed, and it was necessary to provide sufficient power supply capability at the time of the power failure for this purpose.

[0004] However, the power supply capability during a power outage is as follows.
If the power supply capability at the time of a power failure is increased depending on the storage capacity of a storage battery or a storage battery, the power supply device becomes larger, the number of parts increases, and the manufacturing cost increases. For example, in the gaming machine whose specifications are shown in FIG. 12, power is supplied from the power supply device PU shown in FIG. Among them, the + 32V power supply,
With the + 24V power supply, if a power failure occurs, no serious trouble occurs even if the power supply is cut off, so the power supply is immediately shut down when the power failure occurs.

Therefore, the + 32V power supply and the + 24V power supply
The V power supply does not affect the power supply capability at the time of a power failure and does not become a factor that increases the manufacturing cost. The + 12V power supply is a power supply for driving LEDs and switches, and the + 5V power supply is a power supply for driving ICs. Therefore, both of them have a great influence on the game. In order to pay out the prize accurately, the +12 V power supply needs to be supplied with a power supply for monitoring the prize ball switch even during the power failure processing, and the +5 V power supply needs to operate the CPU until the power failure processing is completed. . Usually, it is necessary to supply power for 180 ms, which is the maximum time from when a power failure occurs to when detection of a prize is completed.

This +12 V power supply needs to supply a current of 5.0 A, as shown in FIG.
The V power supply needs to supply a current of 4.2 A, as shown in FIG. Therefore, for 180 ms after the occurrence of the power failure, 5 A of the
It is necessary to provide a backup capacity (such as a power supply capacitor) capable of supplying 4.2 A of power.

This + 12V power supply is a power supply device P shown in FIG.
U is supplied from the power supply terminal PT1, and + 5V power is supplied from the power supply terminal PT2. The backup of the +5 V power supply of the power supply device PU is supplied by the capacitor C1 connected to the input power supply terminal VIN1 of the switching regulator module IC1, and the backup of the + 12V power supply is provided by the capacitor C2 connected to the input power supply terminal VIN2 of the switching regulator module IC1. Supplies. or,
A diode D is connected to the input power terminals VIN1 and VIN2.
2, +32 V power is supplied from the rectification unit SR via D3.

Further, in order to back up the RAM of the main board and the award ball control board for 20 hours by the + 5V power supply, it is necessary to supply a current of 20 μA for 20 hours as shown in FIG. This + 5V power is supplied from the power terminal PT3 of the power device PU of FIG. This power terminal P
At T3, the capacitor C3 connected to the output power terminal VS1 of the switching regulator module IC1 via the diode D4 supplies backup power. Note that the output power terminal VS1 is a terminal that supplies +5 V power to the power terminal PT2 described above. This output power terminal V
S1 has a switching regulator module IC1
According to the standard, +5 V, that is, 4.75 V to 5.25 V is output with an accuracy of 5% in the upper and lower directions. The forward voltage drop of the diode D4 is 0.55V. Therefore, the capacitor C3 is charged with at least Vo = 4.2V.

R backed up by + 5V power supply
AM is based on the specification that the backup voltage is Vi = 2
V. The equation for calculating the RAM backup time with this + 5V power supply is as shown in Equation 2.

[0013]

[Formula 2] t = C (Vo−Vi) / It = 20h = 72000s, Vo = 4.2V, Vi = 2
VI = 20 μA When the capacitance of the capacitor is calculated by Equation 2, C = 0.6
The calculation result of 5F is obtained.

Therefore, the capacitor C3 needs to have a withstand voltage of at least 5.25 V and a standard of having a capacitance of at least 0.65F. 5.5V 1.0F (0.80 to 1.18F) satisfying this standard
Is used.

As described above, conventionally, one 50V15000 μF is used for backup in case of power failure.
The power supply device had to be provided with two power supply capacitors of 0V22000 μF and one power supply of 5.5V1F. An object of the present invention is to reduce the power supply capacity of a power supply device while ensuring that a gaming machine passes through a power failure state without any trouble.

FIG. 5 is a flowchart of a main control processing routine executed by the main board 1 at the time of turning on the power or recovering from the power failure. This main control processing routine is started when Hi of the reset signal (A) is input to the main board 1. First, an internal register setting process of the MPU 71 is performed (S100), and it is determined whether the RAM 17 attached to the MPU 71 is normal (S110). When the power is turned on, it is determined that the RAM 17 is not normal,
Next, initialization processing of the RAM 17 is performed (S120). Thereafter, a power-on command is created (S130). The power-on command is sent to the prize ball control board 3, the symbol control board 7, the voice control board 9, and the illumination control board 11 when the power is turned on, and is actually output by a timer INT process described later. Is done. The power-on command is output to the prize ball control board 3, the symbol control board 7, the voice control board 9, and the illumination control board 11, whereby the following processing is performed.

The prize ball control board 3 performs initialization of the prize ball control board 3 and (initialization of a work area). The symbol control board 7

7 is a flowchart of a timer INT processing routine normally executed by the main board 1 when (ms) occurs. First, the register is saved (S200), then the output process is performed (S210), and the input process is performed (S220). In the output processing, data is output from the MPU 71 to the outside. The output process includes a process of outputting a command to be described later from the main board 1 to the prize ball control board 3, the symbol control board 7, and the illumination control board 11 by the return of the abnormal number of prize balls performed in S230. . The command is transmitted by a strobe signal and a data signal. In the input processing, data is input from outside the MPU 71. The input process includes a process of inputting an operation state of the clear SW 121 attached to the power supply board 15.

Next, abnormality detection and recovery processing are performed (S23).
0), normal gaming machine processing is performed (S240). In the abnormality detection processing, four types of abnormalities are detected as follows, namely, an abnormal number of prize balls, an abnormally full tray, an insufficient supply ball, and a disconnection / short circuit abnormality of the prize ball SW31. Detection of abnormal prize ball count: When sending a prize ball command from the main board 1 to the prize ball control board 3, the prize ball count is added to the prize ball counter, and the timer value is set to xms.

When the prize ball passes through the prize ball SW31, the number of prize balls passing through the prize ball counter is subtracted, and the timer value is set to xms. If the timer value is subtracted and the value of the prize ball counter is 5 or more when the timer value becomes 0, it is determined that the number of prize balls is abnormal (insufficient).

Also, when the value of the prize ball counter is reduced to less than 0, it is determined that the number of prize balls is abnormal (excess). When detecting an abnormal number of prize balls, a command instructing the display of the abnormal number of prize balls to the special symbol display device 47 is sent from the main board 1 to the symbol control board 7, and the abnormal number of prize balls is transmitted to the illumination control board 11. Sends a command to display the illumination pattern.

Detection of lower tray full error: lower tray full S
When W25 is ON, it is determined that the lower tray is full. When the lower tray is full, the main board 1 sends a command to the prize ball control board 3 to instruct the prize ball payout to stop, and the symbol control board 7
Then, a command for instructing the special symbol display device 47 to display a lower tray full error is sent.

Detection of supply ball shortage abnormality: supply ball shortage SW2
When 3 is OFF, it is determined that the supply ball is insufficient. A command for instructing the prize ball control board 3 to stop paying out the prize ball when the supply ball shortage is abnormal, and a command for instructing the symbol control board 7 to display the supply ball shortage abnormality on the special symbol display device 47. Is sent.

Disconnection / short circuit abnormality. When the prize ball SW31 is disconnected or short-circuited abnormally, the main board 1 sends a command to the prize ball control board 3 to stop the prize ball payout, and the symbol control board 7 and the special symbol display device 47 disconnect the prize ball SW31. Sends a command instructing the display of a short circuit abnormality.

In the return processing, the return of the prize ball number abnormality, the return of the lower tray full error, the recovery of the supply ball shortage abnormality, the prize ball S
The four types of recovery from the disconnection / short-circuit abnormality of W31 are executed as follows. Return of winning ball number abnormality: When sending a winning ball command from the main board 1 to the winning ball control board 3, the winning ball number is added to the winning ball counter, and the timer value is set to xms.

When the award ball passes the award ball SW31, the number of award balls that have passed through the award ball counter is subtracted, and the timer value is set to xms. The timer value is subtracted, and when the timer value becomes 0, the value of the prize ball counter is less than 5, and
If the number of prize balls is abnormal, the abnormal number of prize balls is returned (insufficient).

The abnormal number of prize balls (both excess and shortage) is restored when the power is turned on or by a signal for abnormally recovering the number of prize balls. When the prize ball count is abnormally restored, the prize ball control board 3
Transmission of a command instructing initialization of the prize ball control board 3, transmission of a command instructing the symbol control board 7 to display no prize ball abnormality on the special symbol display device 47, and illumination control board 11
Then, a command for instructing the illumination pattern for returning the number of award balls is transmitted.

Recovery of lower tray full error: lower tray full S
When W25 is OFF and the lower tray full error is detected, the lower tray full error is returned. Upon returning from the lower tray full abnormality, the main board 1 sends a command to start the prize ball payout from the main board 1 to the prize ball control board 3, and sends a command to the symbol control board 7 to instruct the symbol control board 7 to not display the lower tray full error.

Recovery of supply shortage abnormality: supply ball shortage SW2
When 3 is ON and the supply ball is abnormal, the shortage of supply ball abnormality is returned. When the shortage of the replenishment ball is restored, a command for instructing the release of payout ball stop release from the main board 1 to the prize ball control board 3 is transmitted, and the special symbol display device 47 is displayed on the symbol control board 7.
A command for instructing the non-display of the supply ball shortage abnormality to be sent.

Recovery of disconnection / short-circuit abnormality of the prize ball SW31: When the prize ball SW31 is OFF and the disconnection / short-circuit of the prize ball SW31 is abnormal, the disconnection / short-circuit abnormality of the prize ball SW31 is restored. When the prize ball SW31 is restored from the disconnection / short circuit abnormality, the main board 1 sends a command for instructing the prize ball control board 3 to stop releasing the prize ball payout, and the symbol control board 7 and the special symbol display device 47 display the prize ball SW31. Sends a command to instruct non-display of disconnection / short-circuit abnormality.

The above is a brief description of S230. After the processing of S230, the normal game machine processing (S
At 240), the main board 1 sends to the prize ball control board 3 and the symbol control board 7 a command instructing the operation state of the special symbol, the operation state of the ordinary symbol, and the payout.

In the instruction of the operation state of the special symbol, detailed description is omitted, but during the customer waiting demonstration, from the start of the change of the special symbol to the confirmation, from the determination of the special symbol to the opening of the first big winning opening. During the period from the opening of the first special winning opening to the closing of the last special winning opening, and the closing of the last special winning opening to the start of the change of the special symbol, the operation at the time of abnormality detection is performed on the symbol control board 7. To instruct.

In the payout instruction, the prize ball control board 3
Specify the number of payouts. After execution of the normal gaming machine processing in S240, the register is restored (S250), and then the INT interrupt permission for releasing the interrupt inhibition by the activation of the timer INT processing is performed (S260), and the timer INT processing routine is executed. Stop once.

FIG. 7 is a flowchart of the NMI processing routine of the MPU 71 of the main board 1. The NMI processing routine is started when a power failure signal output from the power supply board 15 is input to an NMI terminal (not shown) of the MPU 71.

First, the register is saved (S30).
0) Then, it is determined whether or not the Low state is continued for about 1 ms for the power failure signal input to the PORT terminal (not shown) (S310). When the power failure signal is about 1 ms,
If the state is not continued, it is determined that noise is mixed, the register is restored (S320), and the NM
The I process is temporarily terminated. The time is not limited to 1 ms, and may be changed as appropriate within a range that does not hinder other processing.

If it is determined that the power failure signal has been maintained in the Low state for about 1 ms, it is determined that the voltage has actually dropped, and the stack pointer is first saved (S3).
30) Then, after elapse of about 2 ms (S340), and after elapse of about 2 ms, the prize ball SW31 monitoring processing is performed (S3).
50). Waiting for about 2 ms, the timer IN of FIG.
The data of the prize ball SW31 input by the T processing is input without error and stored. This prize ball SW31 monitoring process is performed until 170 ms or more has elapsed (S360).
Here, in order to monitor the prize balls passing after the Low of the power failure signal is input, the period of 170 ms is set as the prize paid out simultaneously with the input of the Low of the power failure signal to the prize ball control board 3. This is because a maximum of about 170 ms is required for the ball to pass through the prize ball SW31. This 170m
s is appropriately changed depending on the specifications of the device.

After performing the award ball SW 31 monitoring process for 170 ms, the RAM 17 is shifted to the access prohibited state (S 3).
70). By setting the access of the RAM 17 to the prohibited state, the data stored in the RAM 17 is prohibited from being changed. Here, the +5 V (A) power supply to the main substrate 1 and the +12 V (A) power supply are stopped, and the MPU is stopped.
71 shifts to the stop state. The storage contents of the RAM 17 are held by a backup power supply.

The MPU 71 shifts to the stop state, and the power supply line DGW (A) supplies +5 V (A) power and +12 V until the power failure processing of the MPU 71 is completed.
(A) Power supply to the power supply is ensured. Thereafter, even after the power supply from the power supply line DGW (A) is cut off, the stored contents are retained for 20 hours or more by the backup power supply supplied from the backup power supply line BKW.

The processing when the power is restored from the power failure state will be described with reference to the flowchart of the main control processing routine of FIG. 5 described above. This main control process is performed by the MPU 71
Is started when the reset signal (A) output from the power supply board 15 is input to the power supply circuit 15. The reset signal (A) is output when power is supplied to the power supply board 15 that has been in a power failure state.

When the main control process is started, as described above, first, a built-in register setting process is performed (S100).
Next, it is determined whether or not the RAM 17 is normal (S110).
If M17 is not normal, or if no data is stored in the RAM 17 such as at the start of operation, the following initialization processing described above is performed (S120 to S140). Description is omitted.

If the RAM 17 is normal (S11
0), here, the access to the RAM 17 is prohibited in S370 by the NMI process in FIG. 7, and if the storage contents of the RAM 17 are retained, the power outage recovery command creation process described above (S160) Is performed, and then a power failure recovery process is performed (S170). Although the detailed illustration of the power failure recovery processing is omitted, the control is shifted to the continuation of the processing at the time of the power failure occurrence based on the current state data stored in the RAM 17. For example, a prize ball is paid out, or a continuation of the big hit game is performed.

As described above, when the power failure occurs, the main board 1 reads the input data such as the detected value of the prize ball SW 31 without leakage and stores it in the RAM 17 without being modified in a normal state. When the power is restored, the stored data is retained by a backup power supply to prevent the stored data from being lost, and when the power is restored, the state of the gaming machine 5 is returned to the state immediately before the power failure. Therefore, the main substrate 1
Will return to the state before the occurrence of the power failure when the power is restored from the power failure.

Next, the processing of the prize ball control board 3 will be described.
FIG. 8 is a flowchart of a main control processing routine executed by the prize ball control board 3 when the power is turned on or when the power is restored. This main control processing routine includes a reset signal (A)
