The delay circuit is changed to a low level.
[0035]
With the above configuration, the main control board 30, the payout control board 31, and other sub-control boards other than the payout control board 31 when the power is supplied to the pachinko machine 10, that is, the symbol control board 32b, the launch control board 33, the lamp The operation of each CPU or the rising state of the control operation of each of the control board 34 and the sound control board 35 will be described with reference to the timing chart shown in FIG.
When the pachinko machine 10 is powered on, the power board 55 generates DC 32V, DC 12V, and DC 5V, which is a battery backup power source (VBB). Each of the generated power supplies is supplied to each control board. The sub-control board including the symbol control board 32b, the payout control board 31 and The main control board 30 performs an operation start-up process as follows.
[0036]
As shown in FIG. 9, when power is turned on to the power supply board 55 (point P1), the voltage of the DC12V power supply gradually rises from 0V to 12V in a parabolic manner. The reset signal 1, which is the output signal of the on-time reset circuit 60, is low level after a lapse of a predetermined time when the voltage of the gradually rising DC12V power source reaches the reference value LV2 (in this specific example, 7.20 to 7.75V point P2) To high level. Thereby, each sub-control board such as the symbol control board 32b excluding the payout control board 31 releases the reset state and starts up the operation related to the control (point P3). The on-time reset circuit 60 does not immediately output the reset signal 1 even when the DC 12V power supply reaches the reference value LV2, but in this specific example, the reset signal 60 rises after the backup start timing by the backup power supply VBB. The reset signal 1 is output after the reset width).
[0037]
The timer 1 circuit 62 outputs about 200 ms after the voltage of the DC12V power supply becomes the reference value LV2, that is, 100 ms after the reset signal 1 output from the reset circuit 60 when turned on changes from low level to high level. The reset signal 2 is changed from low level to high level. The CPU 66 of the payout control board 31 to which the reset signal 2 is inputted executes a security check over about 320 ms from the time when the reset signal 2 becomes high level, and then pays out. The control which concerns on etc. is performed. Accordingly, the CPU 66 of the payout control board 31 starts up the operation about 520 ms (point P4) after the voltage of the DC 12V power supply reaches the reference value LV2.
The timer 2 circuit 63 outputs about 400 ms after the voltage of the DC12V power supply becomes the reference value LV2, that is, 300 ms after the reset signal 1 output from the reset circuit 60 at the time of switching from low level to high level. The reset signal 3 is changed from low level to high level. The CPU 65 of the main control board 30 to which the reset signal 3 is inputted performs a security check as to whether or not the program is a normal program over a period of about 200 ms from when the reset signal 3 becomes high level. Control related to detection and the like is executed. Therefore, the CPU 65 of the main control board 30 starts up the operation about 600 ms (point P5) after the voltage of the DC 12V power supply reaches the reference value LV2.
[0038]
Thus, when the CPU 65 of the main control board 30 starts executing the game control according to the program written in the ROM, each sub-control board has already executed the game control. As a result, even if the CPU 65 of the main control board 30 transmits data to each sub-control board immediately after the power is turned on, each sub-control board is executing the original control, so that the data can be reliably received. .
[0039]
Next, the operation when the power supply to the pachinko gaming machine 10 is cut off will be described according to the timing chart shown in FIG.
When the power supply to the pachinko gaming machine 10 is cut off (point P6), the power supply voltage of DC12V generated by the power supply board 55 decreases substantially immediately after the cut off, but then decreases linearly after a predetermined time. 0V. When the reference voltage LV1 (8.00 to 9.23V in this specific example) is reached (point P7) in the course of gradually decreasing linearly, the backup signal 1 of the backup voltage monitoring circuit 61 of the power supply board 55 is: It changes from high level to low level. As a result, the forced interrupt terminals NMI of the CPU 65 of the main control board 30 and the CPU 66 of the payout control board 31 become low level, and a non-maskable interrupt is applied to the CPUs 65 and 66. As a result, the CPU 65 of the main control board 30 can save the data indicating the current game state, and thereafter prohibit access to the RAM. The CPU 66 of the payout control board 31 can save the data indicating the current prize ball payout state and the ball lending payout state, and thereafter prohibit access to the RAM.

The shutdown reset circuit 64 changes the reset signal 4 output about 100 ms after the fall of the signal at which the backup signal 1 output from the backup voltage monitoring circuit 61 changes from high level to low level from high level to low level (point) P8). As a result, the CPU 65 of the main control board 30, the CPU 66 of the payout control board 31, the CPU 69 of the symbol control board 32b, and the other sub-control boards are stopped simultaneously.
Here, as described above, the RAMs of the main control board 30 and the payout control board 31 are backed up by the battery, and the data stored in the RAM is stored for a predetermined time (about 3 days in this specific example) even when the power is turned off. Retained.
[0041]
As described above, when the power is turned off, the control boards are reset all at once. Moreover, the backup signal 1 output from the backup voltage monitoring circuit 61 is always reset about 100 ms after the high level changes to the low level. As a result, the control can be unified, and the adverse effect that the firing motor is driven even though the main control board 30 stops operating can be prevented.
[0042]
Next, the operation of this specific example having the above-described configuration will be described when the power is turned on and when the power is turned off. Since the processing from the time when the power is turned on until the power is turned off is the same as the conventional one, the detailed description is omitted. Here, for the sake of convenience, first, the process at the time of power-off will be described according to the flowchart shown in FIG.
The flowchart shown in FIG. 11 is a process executed by the CPU 65 of the main control board 30 and the CPU 66 of the payout control board 31 and executed when the signal at which the forced interrupt terminal NMI of each CPU changes from high level to low level falls. Process.
When the processing executed by the CPU 65 and the CPU 66 shifts to this routine, first, processing for writing the predetermined value 55H in a plurality of predetermined areas of the RAM is performed (step S100). The predetermined value to be written may be any value, but 55H or AAH in which each bit in one byte is alternately “1” and “0” is preferable.
[0043]
After a predetermined value is written in a predetermined area of the RAM, data saving is executed (step S110). This data saving process is performed on the main control board 30 in the current game progress status, for example, whether the probability is high probability, whether it is a big hit, whether the symbol is changing on the special symbol display device. In this process, each piece of data indicating the progress of the game, such as whether or not there are pending storages, is written in a predetermined area of the RAM. On the other hand, the payout control board 31 is a process of writing each data indicating the payout state of the current number of prize balls and the payout state of the lending balls into a predetermined area of the RAM. This save process need not be configured to execute this process as long as it is an algorithm that always writes the current state to a predetermined area of the RAM. When the data saving is executed, access to the RAM is then prohibited (step S120).
[0044]
This RAM access prohibition process is to improve the accuracy and certainty of data to be saved by prohibiting writing to the RAM when the power supply voltage is unstable.
When access to the RAM is prohibited, a process of waiting for the reset terminal RES to fall to a low level is executed.(Step S130), Processing stops.
In this specific example, when a forced interrupt is executed, a reset process is always executed after a predetermined time by the shutdown reset circuit 64 even if the power supply is restored thereafter. As a result, it is possible to prevent the adverse effect that the execution of the forced interrupt and the recovery process are alternately repeated when the power source is unstable.
[0045]
In this specific example, the reset signal 4 is output about 100 ms after the backup signal 1 output from the backup voltage monitoring circuit 61 changes from the high level to the low level. Thus, it is calculated.
The CPU 66 of the payout control board 31 executes the power failure processing routine described above when the interrupt terminal NMI becomes low level. At this time, the driving of the ball cutting motor 31c and the ball lending motor 31d is also stopped. When there is a game ball that is paid out immediately before the drive of these motors stops, it is necessary to detect the falling game ball by the prize ball payout switch 31a or the ball rental payout switch 31b. Therefore, it is necessary to ensure a time during which the detecting game balls can be detected by the respective detection switches when the driving of the motor is stopped. On the other hand, if this time is secured too long, the voltage of the 5V power source for driving the IC may be lowered and may not be detected by each detection switch. Therefore, in this specific example, about 100 ms is set due to the balance between the two. Therefore, the distance from each motor to the detection switch and the voltage drop state may be changed as appropriate. In short, it is sufficient to secure a time for detecting a falling game ball within a time during which driving of the IC is guaranteed after the interrupt terminal NMI becomes low level.
[0046]
Next, processing when power is turned on will be described.
When the power is turned on and the security check is completed, the CPU 65 of the main control board 30 executes a “power-on routine” shown in FIG. This routine is executed only once when the signal at which the reset terminal RES changes from low level to high level.
When the process moves to this routine, it is determined whether or not it is normal (step S150). In this specific example, as described above, the DC5V backup power supply is configured to store and hold the data stored in the RAMs of the CPU 65 and the CPU 66 for about three days by the capacitor. For this reason, when the power is restored from a power failure or when the power is turned on in the morning in a normal business state, the value written in the predetermined area of the RAM is stored and held. Thereby, when it is determined that the normal time is reached, the recovery process (step S160) is executed., Processing goes to "return"The
[0047]
In the restoration process, the CPU 65 of the main control board 30 performs preparations for executing the normal process from the data indicating the progress of the saved game, and sends a command code notifying each sub-control board that the power supply has been restored from the power failure. To do. The symbol control board 32b that has received this command code performs a process of displaying a message such as “execution of power failure recovery processing” or “continuing from the game content before the power failure” on the LCD 32a. Or the sound control board | substrate 35 alert | reports that there was a power failure by an audio | voice.
Thereafter, the CPU 64 periodically executes a well-known “main routine” shown in FIG. 13 by a hardware interrupt every 2 ms.
That is, this main routine is composed of the main process and the residual process. Although details are omitted, it is determined whether or not the interrupt is normal (step S200), initial setting (step S210), random number update process (step S220), and each input process. (Step S230), determination processing (Step S240), image output processing (Step S250), output processing (Step S260), and out symbol random number update processing (Step S270) are executed.
Thereby, when a power failure occurs, the CPU 65 of the main control board 30 can continue to control the game from the progress state of the game before the power failure, and does not give the player an unexpected disadvantage or discomfort.
On the other hand, if a negative determination is made in step S150 that it is not normal, an initial setting process (step S170) is executed, and the process returns to “RETURN”. As a case where it is not normal time, it is conceivable that the power is cut off for three days or more, or the data written in the RAM is changed due to a computer runaway or the like. In these cases, the predetermined value written in the predetermined area of the RAM is different from the predetermined value without being stored and held.
In the initial setting process, processes such as clearing the RAM value and transmitting initial data to each sub-control board are executed.
[0048]
On the other hand, when the power supply is turned on and the security check is completed, the CPU 66 of the payout control board 31 executes a “main routine” shown in FIG.
In this routine, it is determined whether or not it is normal time by the same processing as the processing in step S150 described above (step S300). If an affirmative determination is made with normal time, the ball cutting motor is based on the stored data. 31c is driven to execute payout of the winning ball (step S310), and the ball lending motor 31d is driven to execute lending of the lending ball (step S320). Thus, if there is unpaid prize ball data at the time of the power failure, the prize balls are paid out based on the data stored and retained after the restoration of the power failure. Similarly, if there is unpaid ball lending data when a power failure occurs, the ball lending is paid out based on the data stored and retained after the power failure is restored. Thereby, even if a power failure occurs, a player is not disadvantaged.
If it is determined in step S300 that the power failure is not restored, a normal process is executed after the initial setting (step S330).
[0049]
As described above, according to the specific example described in detail, the sub-control board 31 and the main control board 30 including the payout control board 31 and the symbol control board 32b are reset by one power supply board 55 to execute the start-up of the control operation. The control operation is also stopped. As a result, the control can be unified, and the reset circuit is not provided on each control board.DecreaseIt is possible to determine the timing of each control board by checking only the power supply board 55 for the effect of being able to achieve, the effect of preventing the deviation of the control timing due to component errors, the reset timing, etc. Effect.
Further, in this specific example, the data is saved according to the signal output from the backup voltage monitoring circuit 61 before the control operation is stopped, so that the accuracy and certainty of the stored data can be ensured. It also has an effect.
[0050]
In this specific example, the backup voltage monitoring circuit 61 is configured to monitor the voltage of the DC12V power supply, but may be configured to monitor the voltage of the DC32V power supply as shown in FIG. In such a configuration, as shown in the timing chart of FIG. 16, the backup signal that is a forced interrupt signal can be quickly lowered, and a time margin can be given to control. On the other hand, when the power is turned on, the operation timing is as shown in FIG.
In the configuration of the power supply board shown in FIG.30And payout control board31The reset signal generating circuit outputs a reset signal for stopping the control after a lapse of a predetermined time after the backup signal output from the DC32V monitoring circuit falls.Via OR circuitIt is set as the structure which transmits to each control board simultaneously. On the other hand, from the power-on reset generation circuit that monitors the voltage of DC5VVia OR circuitA reset signal for starting the control operation is output to each control board at the same time, and a delay circuit is provided on each control board.32bIncluding sub-control board, payout control board31, Main control board30In this order, the control operation is started. That is, the start-up of the operation is configured to provide a time difference in the operation of each control board based on one reset signal output from the power supply board.
