Ball lending processing for paying out game balls is executed according to the number of lent balls obtained by multiplying the individual pieces (S6). However, when a payout command for winning a prize is received from the main control means 50, a payout process is executed based on the payout control command, for example, 25 game balls are divided into a plurality of 25 game balls. (S7). Then, S5 to S7 are repeatedly executed.

Next, the interrupt processing control will be described with reference to FIG. 14. Every time the payout control command is transmitted from the command transmitting means 56 during the payout control, the above-mentioned payout control is forcibly interrupted and the command is issued. The interrupt process control for reception is started, the received payout control command is stored in a predetermined memory (S20), the interrupt process is terminated, and the process returns to the payout control.

Next, the game operation control executed by the main control means 50 will be described with reference to FIG. When this control is started, as described above, when the clear switch 85 is in the ON state (S31: Yes), first, initial setting for initializing each memory and register of the CPU included in the microcomputer 39C is executed ( S32).

Next, a RAM including a game information storage unit 39j
All the data of 39B, that is, the entire area of RAM39B is cleared (erased) (S33), the initial symbol to be displayed on the symbol display means 21 is set, and the control cycle of repeatedly executing the main game control program of S37 to S46. "2mse
Various initial value setting processing such as setting to "c" is executed (S34). Then, in the remaining time until the predetermined control cycle (about 2 msec) is reached, the symbol data change process (S35) for determining the next symbol by updating, and the numerical value updating process for updating the dummy numerical value not related to the game ( S36) is repeatedly executed.

In this way, the processing time is adjusted by repeatedly executing S35 and S36 for the remaining time from the start of control until about 2 msec elapses. By the way, during execution of S35 to S36, when about 2 msec has elapsed from the start of control, the 2 msec signal generating means 57 outputs a 2 msec interrupt signal to the microcomputer 39.
It is supplied to the CPU of C as an internal interrupt. as a result,
By the CPU, for example, a restart command (RST command) by an internal interrupt is executed, and the processing time adjustment control of S35 and S36 is forcibly stopped midway to jump to the beginning of the game control program, and the main game after S37. The control program (S37 to S46) is repeatedly executed.

Next, the main game control program will be described. First, the opening / closing claw 17a of the symbol starting means 17
A drive signal output process of outputting a drive signal to a solenoid that drives the opening / closing plate 18a of the variable winning means 18 is executed (S37). Next, a switch signal input process of reading switch signals from various switches such as a winning detection sensor, a supply end detection switch and a full detection switch provided in each of the winning means 17 to 19 is executed (S38). Next, a lottery numerical value updating process is executed in which the lottery numerical value is incremented by one using the lottery counter within the range of 300 numerical values from "0" to "299" (S39).

Next, a command output process for outputting a payout control command to the payout control means 70 is executed (S4

Next, processing relating to the special game symbol such as variably displaying the special game symbol on the special symbol display portions 22a to 22c of the special symbol display means 22 is executed (S44).

Next, when the opening / closing claw 17a of the symbol starting means 17 is driven, an operation command output process for outputting a command instructing an operation therefor is executed (S45).
Further, when the opening / closing plate 18a of the variable winning means 18 is driven, an operation command output process for outputting a command instructing an operation therefor is executed (S46). At this time, about 2 msec after executing this main game control program
If has not elapsed, S35 and S36 as described above.
The control time is adjusted by repeatedly executing.

However, when 2 msec elapses during execution of S35 and S36 and the CPU is internally interrupted by the 2 msec interrupt signal, the game control is restarted each time, and the main game control program after S37 is repeated. To be executed.
By the way, when a power failure occurs in the middle of a game and the main power is suddenly cut off, and AC 24 V is no longer supplied to the power supply unit 81, as shown in FIGS.
The "L" level voltage abnormality signal VS output from 2 is supplied to the highest priority interrupt ports of the microcomputers 39C and 46C.

As a result, in the main control means 50, the substantial game control is interrupted, the backup processing is executed by the backup processing program 39f, and the payout control means 70 is also interrupted in the substantial payout control. The backup processing program 46e executes the backup processing. First, the main control means 5
The backup processing control (see FIG. 16) executed by the highest priority interrupt by 0 will be described. First, the backup flag SBF, which is composed of flag information indicating that the main power supply has been cut off, is stored at the start address of the game information storage unit 39j (see FIG. 9) (S61).

Next, the contents (numerical values) of the registers and stack pointer of the CPU of the microcomputer 39C are stored in the game information storage section 39j (S62). In addition, as the information regarding the profit state of the player, a predetermined type of information related to the game state such as jackpot information regarding the special game state, the number of holding balls of the game ball, control command information for paying out the game ball, etc. is additionally added. It is stored in the information storage unit 39j (S63). Next, when the opening / closing plate 18a of the variable winning means 18 is closed immediately, the number of remaining balls remaining in the variable winning means 18 is detected and additionally stored in the game information storage section 39j. (S64).

Next, when the prize balls are paid out by winning, the payout motor is immediately stopped, but the number of remaining balls that have not passed through the detection switch is detected to detect the game information storage section 39j.
Is additionally stored in (S65). Furthermore, while the payout control command is being sent to the payout control means 70,
The transmission control of the payout control command is completed (S6
6). And finally, the checksum data SCD is created, and the checksum data SCD is the game information storage unit 3
It is stored at the end address of 9j (see FIG. 9) (S67),
This backup interrupt processing control ends.

Of course, this backup processing control is
The process is completed in less than about 120 msec from the output of the "L" level voltage abnormality signal VS to the output of the "L" level reset signal SR by the reset signal generating means 83. As a result, in the game information storage unit 39j,
Finally, as shown in FIG. 9, a backup flag SBF at its head address, information about the profit state of the player including jackpot information, held ball number information, winning ball number information, etc., payout control command information, and Checksum data SCD, etc. is stored at the end address.

Here, the checksum data SCD will be briefly described. The game information storage unit 39 shown in FIG.
Each of the storage information stored in j has a 2-byte structure, and the addition result data consisting of 2 bytes (upper 1 byte and lower 1 byte) obtained by adding all of the storage information with a binary number without carrying each digit. The checksum data SCD is the lower 1 byte of data.

Next, the backup processing control (see FIG. 17) executed by the payout control means 70 by the highest priority interrupt will be described. First, a backup flag HBF made up of flag information indicating that the main power supply has been cut off is stored at the start address of the game information storage unit 46j (see FIG. 10).
(S71). Next, the contents (numerical value) of the register and stack pointer included in the CPU of the microcomputer 46C are stored in the game information storage unit 46j (S72). Next, when the prize balls are paid out due to winning, the payout motor is immediately stopped, but the number of remaining balls that have not passed through the detection switch is detected and additionally stored in the game information storage section 46j (S7).
3).

Next, when the game balls are paid out by the ball lending command from the card type ball lending machine 1, the payout motor is immediately stopped, but the number of remaining balls that have not passed through the detection switch is detected and the game information is stored. It is additionally stored in the section 46j (S74). Next, while the payout control command is being received from the main control means 50, the reception control of the payout control command is completed (S75), and the payout control command is stored in the game information storage section 46j (S76). Then, finally, the checksum data HCD is created, and the checksum data HCD is stored in the end address of the game information storage unit 46j (see FIG. 10) (S77), and this backup interrupt processing control ends.

Of course, this backup processing control is completed in a time shorter than about 120 msec until the reset signal generating means 83 outputs the reset signal SR (L) at the "L" level. As a result, in the game information storage unit 46j, as shown finally in FIG. 10, the backup flag HBF, the winning ball number information, the payout control command information, and the checksum data HCD at the end address thereof are shown in FIG. Etc. are stored.

Here, the checksum data HCD will be briefly described. The game information storage unit 3 shown in FIG.
Each of the stored information stored in 9j has a 2-byte structure,
2 bytes (upper 1 byte and lower 1 byte) obtained by adding all of this stored information in binary numbers without carrying each digit
The data of the addition result consisting of is obtained, and the data of the lower 1 byte is obtained as the checksum data SCD.

By the way, the reset signal generating means 83 which has received the voltage abnormality signal VS switched to the "L" level,
The control operation stop reset signal SR (L) is output to the delay circuit 90 and the reset terminals of the microcomputers 40C, 42C, 43C and 46C with a delay of about 120 msec after receiving the voltage abnormality signal VS. Therefore, each microcomputer 39
C, 40C, 42C, 43C, 46C CPU and RAM
Are reset, and the control operation of each CPU is stopped.

Thereafter, when the power is restored from the power failure, that is, when the power failure is resolved, each of the microcomputers 39C, 40C, 42C, 4
Since DC is supplied to the 3C and 46C, the reset signal generating means 83 and the power supply monitoring means 82, the delay signal 90 and the microcomputers 40C, 42C and 4 are supplied from the reset signal generating means 83.
The system reset signal SR (H) of "H" level is supplied to the reset terminals of 3C and 46C, and as described above, the game control of the microcomputer 39C is performed by the other microcomputers 40C and 42C.
The control operation is started after a predetermined minute time t from the control operation by C, 43C, and 46C.

In the payout operation control which was previously started, in this case, the clear switch 85 is operated (ON).
Since it is not played (S1: No), the game information storage unit 46j
When the data of the backup flag HBF stored in is read and the backup flag HBF is normally stored (S8: Yes), the game information storage unit 39j
As described above, the checksum data of the lower-order 1 byte of the addition result data consisting of 2 bytes is created by the checksum processing for the storage information stored in the above (S9).

Next, the checksum data obtained in S9 and the checksum data HCD stored at the end address of the game information storage unit 39j are compared, and if they match (S10: Yes), payout return Processing program 46
The payout return process by c is executed (S11). In this payout return process, the values of the registers and stack pointers stored and held in the game information storage unit 46j are stored in the CPU.
Based on the payout information such as the number of winning balls and the payout control command that are stored and stored,
By paying out the unpaid gaming balls, a return process for continuing the payout operation before power-off is executed. After that, S5 and subsequent steps are repeatedly executed. Here, S9 to S10 correspond to the check data determination unit.

By the way, when the checksum data obtained in S9 and the checksum data HCD read from the game information storage unit 46j do not match, that is, the stored information or checksum data HC stored in the game information storage unit 46j.
When D is stored due to an abnormal situation such as a power failure, which is changed to invalid information due to noise or the like (S10: No), S2 to S4 are executed and the game information storage unit 46j is included. All data in the RAM 46B is cleared (erased) and initialized.

That is, if these two checksum data do not match, it is possible that all or part of the payout information stored and held in the game information storage unit 46j has been changed to invalid information due to noise or the like. This is because when the invalidated payout information is restored, a malfunction occurs in the payout operation, and normal operation cannot be continued from the middle of the payout operation.

On the other hand, in the microcomputer 39C, as shown in FIG.
As shown in FIG. 7, the delay circuit 90 resets and activates the CPU at time T3, which is a short time t after the time T2, and starts its control operation. In this case, since the clear switch 85 has not been operated (ON) (S31: No), the data of the backup flag SBF stored in the game information storage unit 39j is read, and the backup flag SBF becomes normal. If it is stored (S47: Yes), as described above, for the storage information stored in the game information storage unit 39j, the lower-order 1-byte checksum data of the addition result data consisting of 2 bytes is processed by the checksum processing. Is created by calculation (S4
8).

Next, the checksum data obtained in S48 is compared with the checksum data SCD stored at the end address of the game information storage section 39j. If they match (S49: Yes), the game is returned. Processing program 39c
The game return processing by is executed (S50). In this game return processing, the CPU resets the values of the registers and tetak pointers stored and held in the game information storage unit 39j and restores them, and restores from a power failure based on the various game information stored and held. A control command for displaying a screen is transmitted to the symbol control means 60, a control command for displaying the number of reserved balls relating to a normal game symbol or a special game symbol is transmitted to the lamp controller 71, or an untransmitted payout control command is paid out. A return process for returning the game control to a resumable state, such as transmission to the control means 70, is executed.

Then, the main game control program after S37 described above is repeatedly executed. By the way, S
Checksum data obtained in 48 and the game information storage unit 39
If the checksum data SCD read from j does not match, that is, the stored information or the checksum data SCD stored in the game information storage unit 39j is changed to invalid information due to noise or the like due to an abnormal situation such as power failure. Stored in memory (S49: No), S32 to S34
Is executed and the RAM 39B including the game information storage unit 39j
All the data in (1) are cleared (erased) and initialized.

That is, if the two checksum data do not match, all or part of the game information stored and held in the game information storage unit 39j may be changed to invalid information due to noise or the like. This is because when the invalidated information is restored, various malfunctions occur in the game control, and normal operation cannot be continued from the middle of these game operations.

Thus, in the backup process when the main power is cut off, the checksum data SCD of the predetermined type of information stored in the game information storage unit 39j is created and stored in the game information storage unit 39j. When the main power is restored, the checksum data is obtained again based on the stored information that was stored when the main power was cut off, and the obtained checksum data and the already stored checksum data SC
Only when D matches, the game operation is returned based on the predetermined type of information. In this case, the stored information about the profit state of the player and the jackpot information are reliable, and based on these stored information, the jackpot state and the variation operation of the game symbol can be normally continued.

In the backup process when the main power supply is cut off, checksum data HCD of a predetermined type of information stored in the game information storage unit 46j is created and stored in the game information storage unit 46j. When the power is restored,
Checksum data is obtained again based on the stored information that was stored when the main power was cut off, and only if the obtained checksum data and the already stored checksum data HCD match The payout operation is restored based on the information of. In this case, the stored winning ball number and payout control command are reliable, and the payout operation can be normally continued based on the stored information.

By the way, if these two checksum data do not match, there is a possibility that the stored information stored in the game information storage sections 39j and 46j has changed to unreliable information due to noise or the like, and the predetermined type Since the information is not reliable, the game operation is not restored, and the stored information is cleared, it is possible to reliably prevent the jackpot state, the game symbol changing operation, and the erroneous operation of the payout operation. Also, when the main power is restored, the game state storage units 39j, 4
The checksum data is obtained from the predetermined type of information stored in 6j by the checksum process, and the checksum data is stored and retained in the gaming state storage sections 39j and 46j for comparison with the stored checksum data SCD and HCD. It is possible to easily detect an error occurrence (error occurrence) in the stored memory information.

Further, since the checksum data SCD, HCD of the gaming state storage sections 39j, 46j and the checksum data obtained when the main power is restored are the check data obtained by the checksum processing, so a simple checksum By the processing, it is possible to reliably detect the error occurrence (error occurrence) of the stored information stored and held in the game state storage units 39j and 46j. Also, the checksum data SCD and HCD are
Since it is stored at the end of the storage areas of the game state storage units 39j and 46j, the control of writing and reading the checksum data SCD and HCD is simplified.

A modification of the above embodiment will be described. 1] Checksum data SCD, HCD is the game information storage unit 3
You may make it memorize | store in the head part of 9j and 46j, respectively. 2) Instead of the checksum data SCD, HCD, it is possible to add tick data for adding each bit of a plurality of bytes to make it even or odd, or to provide even parity check data or odd parity check data. May be.

3] Instead of the checksum data SCD, HCD, check data for horizontal redundancy check (LRC), check data for vertical redundancy check (VRC), and check data for cyclic redundancy check (CRC). It may be provided. 4] The game information storage units 39j and 46j may be configured by electrically writable non-volatile memories, and the backup power supply 84 may be omitted. 5] RA included in the one-chip microcomputers 39C and 46C
