Abstract

PROBLEM TO BE SOLVED: To secure data transmission from a main control substrate to individual control substrates when supplying power. SOLUTION: The security check time T1 of the main control substrate is equal to or longer than the security check time T2 of sub control substrates and the security check operation of the main control substrate is executed later than the security check operation of the sub control substrates. Thus, when the CPU of the main control substrate starts the execution of the control of a game corresponding to a program written in a ROM, the respective CPUs of the sub control substrates are already executing the control of the game. As a result, even when the CPU of the main control substrate transmits data to the individual sub control substrates immediately after supplying the power, the respective sub control substrates are already executing original control, and hence they surely receive the data without failure.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine, and more particularly, to a gaming machine having a main control board for controlling the progress of a game and a sub-control board other than the main control board.

[0002]

2. Description of the Related Art In a gaming machine, for example, a pachinko gaming machine, a predetermined number of game balls are paid out as a prize ball when a shot game ball wins a winning opening. The game balls that have won each of the winning holes on the game board are temporarily stopped in a safe ball tank, and the stopped game balls are detected one by one by a sensor, and a predetermined number of game balls as prize balls are driven by a motor or the like. After being paid out to the player by the device, the detected game balls are discharged from the safe ball tank. In this conventional pachinko gaming machine, the winning game balls are parked in the safe ball tank, and the prize balls are paid out and then discharged outside the machine, so that even if an unexpected situation such as a power failure occurs, the winning game balls are safe. Because it is parked in the ball tank, it has the effect of not giving a disadvantage to the player.

However, the conventional pachinko gaming machine has the following problems. (1) The configuration is bulky and complicated due to the necessity of providing a safe ball tank. (2) When a power failure or the like occurs, since the data of the number of prize balls to be paid out disappears, the maximum number of prize balls are paid out, and accurate prize balls are not paid out. For example, even when 5 or 10 prize balls should be paid out for one winning ball, 15 prize balls are paid out.

In order to solve these problems, recently, a prize payout control board for paying out prize balls is provided, and data corresponding to the number of prize to be paid out is stored in a memory of the prize payout board. Proposals have been made for battery backup. As the invention according to the proposal,
The applicant of the present application has made the invention described in Japanese Patent Application No. 10-126693, entitled "Ball Ball Game Machine". This proposal has an excellent effect that the mechanism of the pachinko machine can be simplified and an accurate prize ball can be paid out.

[0005]

(1) The pachinko gaming machine generally includes a sub-control board such as the prize payout control board in addition to a main control board that controls the progress of a game, and a power supply board supplies power to each of these boards. It is a target. When power is supplied from the power supply board to each control board, it is unclear which control board is starting up quickly. (2) Thus, for example, when data is transmitted from the main control board to the prize delivery board The problem that transmitted data may not be received. (3) The problems of the above (1) and (2) are as follows. Since the configuration for transmitting data only is adopted, there is a problem that when each control board does not receive data, the same data will not be received twice. The gaming machine of the present invention
The purpose of the present invention is to solve these problems appropriately and provide a sounder gaming machine.

This has the effect of being able to receive.

According to a second aspect of the present invention, when the supply of power from the power supply board is stopped, the electric operation of the main control board is stopped earlier than the electric operation of the sub-control board. The gaming machine according to claim 1, wherein:

According to the second aspect of the present invention, when the supply of power is stopped by the power supply board, the electric operation of the main control board is stopped earlier than the electric operation of the sub-control board. This makes it impossible for the main control board to transmit data when or after the sub-control board has completed the electrical operation. As a result, when the supply of power from the power supply board is stopped due to an instantaneous power failure or the like,
The disadvantage that the main control board transmits data even when the electrical operation of the sub-control board is stopped can be eliminated.

According to a third aspect of the present invention, the gaming machine is characterized in that the main control board and the sub control board include a microcomputer. In the gaming machine according to claim 3, when the power is turned on,

As shown in the figure, the DC 12 V power supplied from the power supply circuit 55 is reset (RES) by the CPU 61 via the voltage monitoring circuit 60 of the main control board 30.
Connected to terminal. Similarly, the DC 12V power supplied from the power supply circuit 55 is connected to the reset (XRES) terminal of the CPU 63 via the voltage monitoring circuit 62 of the prize ball control board 31, and to the XNMI terminal of the CPU 63 via the backup voltage monitoring circuit 64. It is connected to the. The 5V backup power supply of the power supply circuit is connected to the backup terminal (VBB) of the CPU 63.

It is connected to the XNMI terminal which is the input terminal of U63.

With the above configuration, the main control board 30 and the prize ball control board 31 when the pachinko machine 10 is turned on are turned on.
An operation start-up state of each CPU with a sub-control board other than the main control board such as the symbol control board 32b will be described with reference to a timing chart shown in FIG. When the power of the pachinko machine 10 is turned on, the DC3
2V, DC12V, battery backup power supply (VB
B) DC5V is generated. This generated DC
The 12V power is supplied to each control board as shown in FIG.

Here, as shown in FIG. 8, when the power is turned on (point P1), the voltage of the DC 12V power supply gradually rises from 0V to 12V in a parabolic manner. When the voltage of the gradually rising DC12V power supply reaches the reference value LV2, the outputs of the voltage monitoring circuit 62 of the prize ball control board 31 and the voltage monitoring circuit 65 of the symbol control board 32b change from the low level to the high level, and the reset of the CPU 63 is released.
The PU 63 starts the security check operation (point P2). When the power supply voltage of DC12V is the reference value LV2, the output of the voltage monitoring circuit 60 of the main control board 30 maintains the low level state. When the power supply voltage of DC12V rises from the reference value LV2 to the reference value LV1, the output of the voltage monitoring circuit 60 changes from a low level to a high level, and C
The reset of the PU 61 is released, and the CPU 61 starts the security check operation (point P3).

The security check time T1 of the CPU 61 of the main control board 30 is determined by the CPU 63 of the prize ball control board 31.
The security check time T2 of each CPU of the sub control board such as the CPU 66 of the symbol control board 32b is designed to be equal to or longer than the security check time T2. As is well known, the security check is a function of checking whether the contents of the ROM in which the contents of the game are written by the CPUs 30, 31, and 32b, which are one-chip microcomputers, are legitimate contents.

The security check time T1 of the main control board 30 is equal to the security check time T2 of the sub control board.
In addition, the security check operation of the CPU 61 of the main control board 30 is performed later than the security check operation of the sub-control board. Thus, when the CPU 61 of the main control board 30 starts executing the control of the game according to the program written in the ROM, each CPU of the sub-control board has already executed the control of the game. As a result, immediately after the power is turned on, the CPU 61 of the main control board 30
Can transmit data to each sub-control board, and since each sub-control board is executing the original control, the data can be reliably received. In this specific example, the security check time T1 is about 439 ms, and the time from when the power of the CPU 61 of the main control board 30 is turned on to when the control of the game is executed is about 529 ms to 549 ms. The security check time T2 is about 200 ms, and the time from when the power is turned on to when the CPU 63 of the prize ball control board 31, which is one of the sub-control boards, controls the game is about 20 ms.
It is 2 ms to 203 ms.

Next, the operation when the power supply to the pachinko gaming machine 10 is cut off will be described with reference to a timing chart shown in FIG. When the power supply to the pachinko gaming machine 10 is interrupted (point P6), DC12V
Although the power supply voltage of the power supply voltage drops sharply immediately after the cutoff, it drops substantially linearly thereafter and becomes 0 V after a predetermined time. In the course of this linearly decreasing, the aforementioned reference voltage LV1
(Point P7), the output voltage of the voltage monitoring circuit 60 of the main control board 30 changes from the high level to the low level, and the CPU 61 is reset. Thereafter, as the time elapses, the power supply voltage of DC12V gradually decreases and reaches the reference voltage LV3 (point P8).
The output voltage of the backup voltage monitoring circuit 64 changes from the high level to the low level. As a result, the XNMI terminal of the CPU 63 of the award ball control board 31 becomes low level,
A non-maskable interrupt is applied to the CPU 63.

When the power supply voltage of DC12V further decreases from the reference voltage LV3 to reach the reference voltage LV2 (point P
9) The output voltage of the voltage monitoring circuit of each sub-control board, such as the voltage monitoring circuit 62 of the award ball control board 31 and the voltage monitoring circuit 65 of the symbol control board 32b, changes from high level to low level. Thus, the CPU of each sub-control board is reset. Here, the RAM of the prize ball control board 31 is backed up by a battery, and the RAM is stored even when the power is turned off.
Is stored for a predetermined time (about 1 hour 20 minutes to about 3 hours 30 minutes in this embodiment). By the way, as described above, the XNMI terminal is enabled before the CPU 63 of the award ball control board 31 is reset. As a result, the CPU 63 prohibits access to the RAM and prevents writing. As a result, the contents of the RAM in a stable state before resetting can be backed up by a battery instead of backing up the contents of the RAM in an unstable state that is a reset state.

As described above, when the power is turned off, the CPU 61 of the main control board 30 is reset first, and then each CPU of the sub-control board is reset. This has the effect that each sub-control board can reliably receive data transmitted by the CPU 61 of the main control board 30 before the power is turned off. In this specific example, the reference voltage LV1 is 9.39V to 10.21V, the reference voltage LV3 is 8.00V to 9.23V,
The reference voltage LV2 is designed to be 7.20V to 7.75V.

The configuration for transmitting winning data from the main control board 30 to the prize ball control board 31 is described in Japanese Patent Application No. 10-12 / 1998.
Since the configuration is substantially the same as the configuration shown in the “ball game machine” of No. 6693, only a brief description will be given. Main control board 30
Is a first-type start-up switch 36a provided in the ordinary electric accessory 36, a count switch 40b provided in the special winning opening 40, and a plurality of other winning opening detection switches 52 provided in each of the other winning openings. When it is detected that there is a prize, a process of incrementing (+1) the data PD1, PD2, PD3 is executed. The data PD1 corresponds to a winning opening in which five winning balls are provided for one winning ball. The data PD2 corresponds to a winning opening in which 10 winning balls are played for the winning ball 1. The data PD3 corresponds to a winning opening in which 15 winning balls are played for the winning ball 1. This increment processing is executed for a predetermined time, and after a predetermined time elapses, the data PD
1, PD2 and PD3 are transmitted to the prize ball control board 31,
Cleared to zero when transmitted.

On the other hand, upon receiving the transmitted data PD1 to PD3, the award ball control board 31 converts the received data PD1 into the unpaid data MPD1 and the data PD2 from the unpaid data MPD.
2. Add the data PD3 to the unpaid data MPD3. If the value of each of the unpaid data MPD1 to MPD3 is not zero, the CPU 63 of the prize ball control board 31 drives and controls the ball cutting motor 29b to execute the prize ball payout.
After the payout balls are paid out, the value is decremented (−1), and the same processing is executed until the value becomes zero. That is, if the value of the unpaid data MPD1 is not zero, the ball cutting motor 29b
Is driven to pay out five game balls as prize balls, and then the value of the unpaid data MPD1 is decremented. The fact that five game balls have been paid out means that the prize ball payout SW 29a
Is detected by Similarly, if the value of the unpaid data MPD2 is not zero, the ball cutting motor 29b is driven to pay out 10 game balls as prize balls, and then the unpaid data MPD is
Decrement the value of one. If the value of the unpaid data MPD3 is not zero, after driving and controlling the ball cutting motor 29b to pay out 15 game balls as prize balls, the unpaid data MPD is
Decrement the value of one.

The data of the unpaid data MPD1 to MPD3 is stored in a built-in RAM of a CPU 63 which is a one-chip microcomputer.
Is stored. As described above, the VB of the CPU 63
A battery backup power of 5 V DC is supplied to the B terminal from the power supply board 55. Therefore, even if the power supply to the pachinko gaming machine 10 is stopped due to a temporary power failure,
When the power outage is resolved and the power is supplied again, C is set according to the values of the unpaid data MPD1 to MPD3 stored and held.
The PU 63 can execute award ball payout control.
Thus, no unexpected disadvantage is given to the player. Further, as described above, before the power is turned off and the reset state is established, the CPU 63 is subjected to the forced interrupt by the XNMI, and executes the process of prohibiting the access to the RAM. As a result, the DC5 that is reset
There is also an effect that the writing to the RAM due to the unstable state of the V power supply is prohibited in advance, and the data stored and held by the battery backup can be suitably stored as normal data.

Here, in this specific example, the order of the data transmitted from the main control board 30 is
Main control board 3 memorizes other than MPD3 and pays out prize balls.
A configuration in which execution is performed in the order transmitted from 0 is adopted. Thereby, the payout of prize balls can be executed in the order of winning in each winning opening. On the other hand, after the restoration of the power failure, as shown in the flowchart of FIG.
(Step S10)
0), whether or not the data of the unpaid data MPD3 is zero (step S110), whether or not the data of the unpaid data MPD2 is zero (step S120), and whether or not the data of the unpaid data MPD1 is zero (step S130). Is determined. As a result of the determination, if each data is not zero, the payout is executed until the data with a large number of winning balls becomes zero, and the process shifts to paying out the next data with a small number of winning balls (step S1).
40 to S160). Thus, according to this specific example, payout of prize balls is normally performed in the order of prize holes in each prize port, and after recovery from a power failure, prize balls are paid out from prize ports with a large number of prize balls. As a result, after the restoration of the power outage, the player can quickly acquire the prize ball and have an effect of giving the player a sense of security.

The processing in step S100 is performed by X
When the NMI is enabled to prohibit access to the RAM, data such as 55 (H) or AA (H) is written to a predetermined area of the RAM, and whether the written data has not changed after restoration from the power failure. Is a process for determining whether the backed up data is normal or not. When the data is changing, it can be regarded as CPU runaway. The prize ball control board 31 performs ball lending control when the lending button 16 is pressed, in addition to the prize ball control. Even in this ball lending control, even if a power failure occurs during ball lending, the remaining number of ball lending or the number of ball lending already paid out can be stored and stored, and unexpected disadvantage is given to the player. There is no.
