FIG. 5 is a flow chart of a control program executed by the CPU 50. The program is periodically executed according to the reset signal S6 from the reset circuit 54.

First, in step 501, it is determined whether or not the power is turned on, and if the answer is affirmative (Yes), the process proceeds to the initialization process (step 502), the switch flag in the RAM 52, the winning number data, The command data and the control output data are cleared, and a random number is generated by a random number generating means including a refresh counter (not shown) in the CPU 50, and this random number is used as the display data of the lower display 23, and the winning probability is random. Try to be. Note that when the power is turned on, the reset circuit 400 operates and the input / output circuit 40 is held in the input mode, so that the operation of the gaming machine due to an erroneous control output is prevented.

Next, in step 503, it is determined whether or not the level of the winning display signal S2 supplied from the abnormal state detection circuit 320 of the switch input detection circuit 30 is in the high level state for a predetermined time. For such a determination, a soft timer, which is set to a predetermined time longer than the normal duration of the positive polarity pulse output S2 generated during the opening operation of the count switch 19, for example, 1 second, is started at the time when the output S2 shifts to a high level, The CPU 50 monitors whether the soft timer has timed out.

When the count switch 19 is operating normally, the determination result of step 503 is negative, and the process proceeds to step 504. If the prizes of the chuckers 11 to 13 have not been won yet, the number of starting memories representing the number of wins to the chucker is 0, and it is then determined whether or not the LED is rotating (step 506). Since the content of the command data is 0 and not 1 indicating that the LED is rotating, this determination result is negative,
Further, all of the answers to the determinations in steps 507 to 510 executed subsequently are negative. Therefore, the movable door drive solenoid 17, the lamps 24 and 25, and the speaker 27
Is maintained in the deenergized state (step 511), and the current loop of this program ends.

On the other hand, when the game ball wins any of the chuckers 11 to 13, the start switch 18 is closed, the input terminals 301 and 302 of the switch input detection circuit 30 are connected, and the output S1 of the inverter 131 is high. It becomes a level state. Based on the contents of the switch flag corresponding to the high-level output S1, the determination result in step 504 is affirmative and 1 is added to the number of stored starts (step 505).

In the case of continuous winning, a predetermined number of times, for example, 4
Such addition is executed only up to the number of times. Next, since the content of the command data is still 0, steps 506-51
When step 512 is reached via 1, it is determined that there is a starting memory number, and this memory number is displayed on the upper display 22.
Then, 1 is subtracted from the number of starts (step 513),
After the soft timer in the CPU 50 is set to a predetermined maximum LED rotation time, for example, 5 seconds (step 514), the command data is updated from 0 to 1 indicating that the LED is rotating (step 515), and the current loop of this program ends. To do.

The answer to step 506 of the next loop is affirmative, and LED rotation processing is performed (step 516).
By the lower LED drive circuit 63 according to the control output S13, the display content of each of the display units 23a to 23c of the lower display 23 is set to 1.
Will be updated one by one. In order to randomize the LED rotation, the display update cycle of each of the display units 23a to 23c is, for example, 1: 2: 3.
Is set to. This LED rotation processing is automatically stopped after the elapse of a predetermined maximum time or the push button stop switch 26
Is stopped after being pressed after being pressed (that is, when the positive polarity pulse output S2 falls), and at this time, the command data is updated to 2 indicating that the LED rotation is stopped. Then, during the LED rotation process, the start lamp 25 is turned on according to the outputs of the start lamp and the sound drive circuits 65 and 66 according to the control outputs S15 and S16, and the rotating sound is output from the speaker 27.

The determination result of step 507 of the next loop is affirmative, the process proceeds to the LED rotation stop process (step 517), and the display contents of the display units 23a to 23c are sequentially stopped. More specifically, in order to ensure the randomness of the LED rotation stop, a predetermined address of the RAM 52 is updated every time the reset signal S6 is generated, and takes a value of 0 to 4, for example.
While storing random control information for stopping ED rotation,
Display contents of the first display unit 23a when any of five kinds of predetermined time according to the value of the random control information at the time after the predetermined longest time has passed or when the push button 26 is released. Update of the display unit 23b,
The update of 23c is stopped sequentially. Then, the command data is updated to 3 indicating that the LED is being determined.

Therefore, in the loop immediately after the completion of the LED rotation stop processing, the answer in step 508 becomes affirmative, and the processing shifts to the LED determination processing (step 518) to display the display content of the lower display 23 in the RAM 52 corresponding thereto. Determine based on the data. As a result of the discrimination, the display device 2
If the three-digit digital number displayed on the first to third display units 23a to 23c of 3 is not a doublet, the soft timer in the CPU 50 is set to a first predetermined time, for example, 0.4 seconds, while an even number is set. If it is a doublet, the second predetermined time, for example, 6 seconds, and if it is an odd-numbered doublet (big hit prize), the third
The predetermined time is set to 20 seconds, for example. Also, the command data is updated to 4 indicating that the attacker is being opened.

The answer to the determination in step 509 in the next loop of this program is affirmative, and the attacker opening process is executed (step 519). That is, the solenoid 1 is controlled by the solenoid drive circuit 61 associated with the control output S11.
7 operates, and the movable door 16 of the attacker 14 is opened for the time set according to the combination of the numbers displayed on the display 23. However, at the time of winning the big hit, the movable door 16 is closed when the number of winnings to the attacker 14 reaches 10 even if the third predetermined time has not elapsed.

Further, during opening of the attacker, the start lamp 25
Is turned on and an opening sound is output from the speaker 27. Further, when the central pocket 15 is won, the central pocket lamp 26 is blinked, and flag information for displaying the winning is stored in the RAM 52 unless the number of times of winning reaches a predetermined number, for example, 10 times.

When the first, second or third predetermined time elapses after the attacker is opened, the command data is updated to 5 indicating that the delay process is in progress, and step 510 of the next loop.
Since the determination result of is affirmative, the delay process is executed (step 520). That is, when it is determined that there is no winning in the central pocket 15 based on the flag information described above,
On the other hand, if there is such a prize, the attacker 14 is opened again while shifting to the aforementioned step 511. Therefore, the attacker 14 continuously wins 1 in the central pocket 15 on condition of winning.
It has been opened for 0 times.

If the result of the determination in step 503 is affirmative, that is, if there is an abnormality in the operation of the count switch 19 or the like, the operation shifts to the deactivating process (step 521), the control output data held in the RAM 52 is cleared, and the solenoid 17 is operated. Deactivate all the operating parts such as and deactivate the game machine.

FIG. 6 shows a flow chart of the lower digital display control program executed by the CPU 50. As described above, the opening and closing of the attacker 14 that greatly affects the winning profit of the player is performed according to the combination of the numbers displayed on the display 23 and according to the number of winnings to the attacker 14 and the central pocket 15. , The parameter value indicating the game progress status such as the number of winnings and the attacker 14
It is of interest to the player whether the opening / closing operation of the is accurately performed according to these parameter values. Therefore, as described below, one display device 23 is driven in a plurality of display modes to display various display contents.

If any of the determination results of steps 602 to 603 is affirmative, that is, if any one of the LED rotation and the LED determination processing is being executed, the lower LE according to the control output S13.
By the output of the D drive circuit 63, the first display mode is displayed on the lower digital display 23, and each display unit 23 of the display 23 is displayed.
Any one of the digital numbers 0 to 9 is displayed on a to 23c (steps 604 to 606). As described above, this digital number is updated while the LED is rotating.

On the other hand, steps 601-603 and 607
If the answer to each of the above is negative, that is, if it is determined by the LED determination processing that the three-digit display number on the display is not an odd-numbered doublet, the process proceeds to the LED drive stop processing and each display unit 2
3a to 23c are deactivated (step 608), and the current loop of this program ends.

When it is determined in step 607 that the display number of the display unit 23 is a doublet, the display mode of the display unit 23 is switched from the first mode to the second mode according to the output of the lower LED drive circuit 63. , The first and third display units 23 of the display unit 23 based on the winning number display data in the RAM 52.
The number of continuous winnings to the central pocket 15 and the number of winnings to the attacker 14 during each opening operation of the attacker 14 are separately displayed on a and 23c by a hyphen displayed on the second display portion 23b (step 609). ~ 6
11).

This second display mode continues during execution of the attacker opening process or the delay process (step 612).
613). That is, during opening of the attacker, the central pocket 1
If there is no prize for 5, LE immediately after the opening of the attacker
While the D drive stop processing is performed (step 608), if there is such a prize, the second display mode is maintained and the attacker 14 waits for the start of opening of the attacker 14 even during the daylay processing after the end of attacker opening, and the attacker 14 is opened again. Then, the display in the second display mode is restarted.

In the above embodiment, the number of winning balls to the attacker 14 is used as the opening prevention condition parameter of the movable door 16, but the opening time of the attacker 14 may be used instead. In this case, the game machine may be deactivated when the opening time of the attacker 14 exceeds a predetermined time.
