Therefore, it is conceivable to provide an abnormality determining means for determining whether an abnormality such as a disconnection or the like of the winning ball detector or an abnormality such as a ball clogging has occurred. The abnormality determining means may be configured to determine that an abnormality has occurred based on the output of the winning ball detector being in an abnormal level state. However, in the case of such a configuration, the abnormality due to the failure such as the disconnection can be discriminated because the output becomes an abnormal level, but in the case of an abnormality such as a ball clogging, when the winning ball is detected. Since the signal is in the same level as the signal output from the winning ball detector, there is a disadvantage that an abnormality such as a ball clogging cannot be determined.

An object of the present invention is to prevent inconvenience in which many profits are unevenly imparted only to a skilled person who is excellent in ball hitting operation technology, to fair the game service, and at the same time, in the variable winning apparatus. If there is a malfunction such as a ball clogging or the prize ball detector is intentionally removed from the game, it is possible to properly determine the occurrence of the abnormality, and the amusement store suffers an unexpected disadvantage or An object of the present invention is to provide a ball game machine capable of avoiding trouble with a game store.

[0006]

In order to achieve the above object, the present invention is provided in a game area (1) in which a game ball is driven, and is in a first state that is disadvantageous to the player and a second state that is advantageous to the player. In a ball game machine equipped with a variable winning device (5) that can be converted into a state, a specific game state detecting means (DCD) for detecting that a predetermined specific game state has occurred, and the variable prize. When the device is in the second state, a winning ball detecting means (31) for detecting a game ball that has won the variable winning device, and the variable winning device is set to the second based on the detection output of the specific game state detecting means. State,
When the number of winning balls detected by the winning ball detecting means reaches a predetermined number, the drive control means (CNT6, FF8) for putting the variable winning device in the first state and the output of the winning ball detecting means Abnormality determining means (D) for determining that an abnormality has occurred when the level is in a predetermined level for a predetermined time.
And TC).

According to the above-mentioned means, by the operation of the drive control means, when the predetermined specific game state occurs, the variable winning device is converted from the first state to the second state, and the variable winning is achieved. The variable winning device is converted to the first state when the winning ball detecting means for detecting the game balls winning the device detects a predetermined number of winning balls. Then, by the function of the abnormality determining means, it is determined that an abnormality has occurred when the output of the winning ball detecting means is in a predetermined level state for a predetermined time. That is, when an abnormality occurs in the winning ball detecting means due to a failure such as disconnection, the winning ball detecting means outputs a predetermined level of output. On the other hand, even in the case of an abnormality such as a ball clogging, the winning ball detecting means keeps outputting a signal of the same level as when the winning ball is detected. In this way, depending on whether there is an abnormality caused by a failure or an abnormality caused by a ball clogging, the winning ball detection means continuously outputs a signal in a certain level state. Therefore, even if these different kinds of abnormalities are common in that a signal of a certain level state is continuously output, the output from the winning ball detecting means has a predetermined level for a predetermined time. By performing the abnormality determination based on the state, it is possible to perform the abnormality determination regardless of whether the abnormality caused by the failure or the abnormality caused by the ball clogging has occurred.

The detection signals of the switches SW1 and SW2, which are the specific winning detectors, are the waveform shaping synchronous differentiating circuit DFR1.
And DFR2 are input to this synchronous differentiating circuit DFR.
1 and DFR2 are operated by pulses Ps ₁ and Ps ₂ from a phase shift pulse generation circuit PG that generates pulses whose phases are shifted from each other based on a clock CK1. for that reason,
Even if the detection signals are formed at the switches SW1 and SW2 at the same time, they are detected at different timings at the synchronous differentiating circuits DFR1 and DFR2, and each one-shot pulse P is generated.
₁ and P ₂ are generated. The pulse signals P ₁ and P ₂ are input to the right shift terminal of the shift register SR1 which also serves as a storage means of the specific winning ball through the common OR gate G ₁ and AND gate G ₂ , and this shift register SR1 Is
Each time the start signal S ₁ or S ₂ is input, outputs Q ₁ , Q ₂ ,
The shift operation is performed so that Q ₃ and Q ₄ are sequentially set to the high level.

As a result, when the specific winning balls are continuously generated, the LED lamps LED1 to LED4 are sequentially turned on. In addition, the output Q ₁ ~ of the shift register SR1
Q ₄ has a common OR gate G ₆ and a flip-flop F
The signal is input to F ₁ and the gate G _{7 is} output from the phase shift pulse generation circuit PG.
The start signal S of the variable display device 4 is formed by being taken in in synchronism with the pulse Ps ₃ of the timing supplied via the. Based on the start signal S, the pulse P ₃ generated by the synchronous differentiating circuit DFR3 is input to the left shift terminal L of the shift register SR, so that the shift register SR1 is generated each time one start signal S is generated. Since the high level state of the outputs Q _{1 to} Q ₄ of is shifted to the left, the memory of the specific winning ball is decreased by "1", and the LED lamps LED1 to LED4 are turned off one by one from the right. go.

By the start signal S, the data "1" is latched in the latch circuits LT1 to LT4 formed of flip-flops, and the output Q thereof is held at the high level. As a result, the AND gates G _{11 to} G ₁₄ output drive signals in synchronization with the clock CK2 to the counters CNT1 to CNT4. Therefore, the counter CNT
1 to CNT4 simultaneously start counting operation. Counter C
The outputs of NT1 to CNT4 are the decoder drivers DD1 to DD1.
It is supplied to the DD 4 and is decoded to drive the segment type display LEDs A to LED D. As a result, the LED
The numbers "0" to "9" displayed on the LEDs A to LED D start to rotate. At this time, at the same time, the output Q of the latch circuit LT4 is supplied via the AND gate G ₁₉ to the sound effect generation circuit SG for generating a sound effect similar to the rotation sound of the roulette, and the output thereof is supplied by the amplifier circuit AMP. It is amplified and supplied to the speaker SPK to generate a roulette rotation sound.

Further, the output of the gate G ₁₉ is synchronized with the clock CK5 via the AND gate G ₆₁ as shown by the symbol, and further supplied to the drivers DR1 and DR2 via the OR gates G ₆₂ to G ₆₄ and G _66. Then, the display lamps L ₁ and L ₂ are slowly blinked. The above counter C
The output of CNT4 of NT1~CNT4 via a data selector SEL1 deco - entered in Dadoraiba DD4, but selector SEL1 In the initial state, to pass the signal at terminal A side by the low output Q of the flip-flop FF ₄ Counter C
The output of NT4 is supplied to the decoder driver DD4, and the display rotates.

When the display fluctuation stopping means 30 is operated and the switch SW3 is turned on during the display rotation, the OR
The flip-flop FF ₂ is operated via the gate G ₃ ,
The high level output Q of the flip-flop FF ₁ is taken in and the output Q is changed to the high level, whereby the reset of the shift register SR ₂ is released. Therefore, the shift register SR ₂ shifts in synchronization with the clock CK3, and the outputs Q _{1 to} Q ₄ sequentially change to the high level. The output Q ₁ to Q ₄ are, OR gate G _{2 1} ~G
_The above latch circuit (flip-flop) LT1 via ₂₄

The supply of 3 is cut off by the gate G ₄ when the output Q ₄ becomes high level.

On the other hand, the LED lamps LED A to LED D
When the display of is rotated, the start signal S causes
Since the output Q of the flip-flop FF _{10 at} the lower part of the drawing is changed to the high level, the display lamp LED 5 is turned on by the driver DR5 and the operation validity of the switch SW3 of the variable display stopping means 30 is displayed. Then, lamp L
When 30 seconds have passed since the ED5 was turned on, the flip-flop FF is output by the output from the timer counter TMC1.
The output Q of ₂ is changed to the high level. As a result, the shift register SR2 operates in the same manner as when the switch SW3 is turned on.

The timer counter TMC1 is reset by the start signal S and released from the clock C
K4 performs counting operation in synchronization with the output and after 30 seconds is changed to the high level, which will isolate supply of the clock CK4 through the gate G ₅ counting operation is stopped. Thus, the output of the timer counter TMC1, just as the shift register SR2 is operated to open the AND gate G ₁₅ ~G ₁₈ by its output,
Through the OR gate G ₂₅ ~G ₂₈ to supply the output Q ₁ to Q ₄ of the shift register SR2 to the preset terminal P of the counter CNT1 to CNT4. Therefore, the counters CNT1 to CNT1
The CNT 4 sequentially takes in the numerical values of the random numerical value generation circuit RNG that generates random numerical values, and the LED display section L
ED A ~ LED D specific mode (big hit or medium hit)
Display numbers in combinations other than.

When the counters CNT1 to CNT4 are stopped (including presetting of random numerical values), the counter CN is applied in the decision circuit DCD to which the output is supplied.
It is determined whether or not the outputs of T1 to CNT4 are in a big hit state (a state in which all four numerical values match) or a medium hit (a state in which any three of them match), and a big hit signal C ₁ , corresponding to each state. The hit signal C ₂ or the lose signal C ₃ is output. When the loss signal C ₃ is output, a signal for generating a corresponding sound effect is output from the sound effect generating circuit SG, is supplied to the amplifying circuit AMP, is amplified, and the sound effect is generated from the speaker SPK.

Further, the loss signal C ₃ is supplied to the OR gate G _56.
And a flip-flop FF ₃ via the OR gate G _33.
Is supplied to the input terminal to operate it and change its output Q to a high level. Then, the reset of the timer counter TMC4 is released and the time counting operation is started. When one second has passed, a time-up signal is output and the OR gate G
It is supplied to the flip-flop FF ₃ via ₃₂ and reset. Thus, along with the timer counter TMC4 is reset, it AND gate G ₈ output / Q goes high level of the flip-flop FF _3, G ₇
It is supplied to the flip-flop FF ₁ via and is operated. Therefore, at this time, if the shift register SR1 stores the specific winning ball, the start signal S is output again. Moreover, the loss signal C ₃ is supplied to the flip-flop FF ₂ through the OR gate G ₃₃ and G _31, the detection signal from the stop switch SW3 during rotation of the display of the variable display device (counter CNT1 to CNT4) Is returned to a state in which it can be accepted.

Next, in the control circuit, the counter CNT1~CNT4 is operated by the occurrence of a particular winning ball (on the switch SW ₁ or SW _2), when the counter is stopped by the signal stop switch SW _3,
If the values of any three of the counters match, it is detected by the decision circuit DCD and the medium hit signal C ₂
Occurs. Then, the middle hit signal C ₂ is supplied to the sound effect generation circuit SG to form a drive signal for generating the corresponding sound effect, which is amplified by the amplifier circuit AMP and supplied to the speaker SPK, which is more effective than the speaker SPK. A sound is generated, and is supplied to the drivers DR1 and DR2 via AND gate G ₆₅ and NOR gates G ₆₂ to G ₆₄ and G ₆₆ as indicated by a symbol, and the display lamp L
₁ and L ₂ repeat rapid blinking in synchronization with clock CK ₄ .

The medium hit signal C ₂ is supplied to the OR gate G _55.
Is supplied to the driver DR6 via the solenoid So
L is driven to open the variable winning device and OR
The output of the gate G ₅₅ is supplied to the reset terminal of the timer counter TMC3, and the timer counter TMC3 is operated to release the reset. Then, after 6 seconds, the time-up signal is output and supplied to the AND gate G ₅₂ , so that the medium hit end signal is formed and is transmitted to the flip-flop FF ₂ via the OR gates G ₃₃ and G _31. The shift register SR ₂ is supplied to the shift register SR _{2 to} be reset, the output Q thereof is reset to change the output Q ₄ thereof to the low level, and thus the decision circuit DCD for monitoring the signal has finished the medium hit state. Is detected, the medium hit signal C ₂ is changed to a low level to stop the driving of the solenoid SoL, the generation of a sound effect, and the lighting of the lamps L ₁ and L ₂ .

The medium hit end signal is the OR gate G _33.
It is supplied to the flip-flop FF ₃ via and operates it to change the output Q to the high level. Then
The reset of the timer counter TMC4 is released and the time counting operation is started. Then, the output time-up signal after a lapse of one second, the flip-flop FF ₃ is reset, whereby with the timer counter TMC4 is reset, the output / Q of the flip-flop FF ₃ is A
It is supplied to the flip-flop FF ₁ via the ND gates G ₈ and G ₇ to operate it. Therefore, at this time, if the specific winning ball is stored in the shift register SR1, the start signal S is output again. Further, the flip-flop FF ₂ is reset by the medium hit end signal, and the stop signal can be accepted while the next display (counters CNT1 to CNT4) of the variable display device is rotating.

On the other hand, the determination if the circuit jackpot signal C ₁ from the DCD is output, the jackpot signal C ₁ is the corresponding sound effect is supplied to the sound effect generator SG (fanfare)
Is generated. When the fanfare ends, the output of the AND gate G ₅₁ is changed to the high level by the signal q output from the sound effect generation circuit SG, so that the AND gate G ₅₄ is opened and the big hit signal is output via the OR gate G _55. C ₁ is supplied to the driver DR 6 to drive the solenoid SoL, and the special variation winning device 5 is opened. The jackpot signal C ₁ is supplied to the flip-flop FF ₅ , and its output Q is changed to a high level to store and hold the jackpot state. Further, this signal C ₁ is applied to the gate G ₈
To the synchronization signal P from the phase shift pulse generation circuit PG to close the gate G ₇ to change its output to low.
the s ₃ made so as not to be supplied to the flip-flop FF _1. As a result, the next start signal S is not generated during the big hit.

Further, the jackpot signal C ₁ is supplied to the second data selector SEL2, and the signal input to the terminal B is replaced with the signal input to the terminal B instead of the signal input to the terminal A.
Supply to NT4. Then, since the output from the continuation number counter CNT5 is applied to the terminal B of the selector SEL2, the continuation number is loaded from the selector SEL2 to the counter CNT4, and further, the selector SEL2.
1 to the decoder driver DD4. As a result, the segment type LED display LED D displays the number of continuations. Other LED indicators LED
A to LED C remain in the jackpot state. However,
Through the AND gate G _{4 7} being opened by the output / Q of the flip-flop FF _8, jackpot signal C ₁ is AND
Since it is supplied to the gate G ₄₈ , LED A to LED C remain the original display (numerals), and LED D shows “0”.
The display blinks in synchronization with the clock CK4. Moreover, continued counter CNT5, since earlier are adapted to reset is released by the output Q of the flip-flop FF ₅ is set at the same time as the big hit occurs in the reset state, LED D is the first big hit time of occurrence Is displayed with an initial value "0".

Further, the jackpot signal C ₁ is, as shown by the symbol, an AND gate G ₆₃ which is normally opened by the high level output / Q of the flip-flop FF ₈ and an AND gate G ₆₇ to which the clock CK4 is applied. To the driver DR3 and further via the OR gate G ₆₄ to the driver D3.
Since it is also supplied to R1, when a big hit occurs, the lamps L ₁ and L ₃ are blinked in a quick cycle in synchronization with the clock CK4. The output signal of the AND gate G ₅₄ , which serves as a solenoid drive start signal for opening the special variation winning apparatus, is supplied to the timer counter TMC3 as well as the driver DR6 to release the reset state. The timer counter TMC ₃ counts the clock CK4 and outputs a big hit end signal E ₁ after 30 seconds have elapsed. This end signal E ₁ is the AND gate G ₅₃ opened by the big hit signal C _1.
And a flip-flop FF ₈ via the OR gate G _45.
And changes its output Q to a high level. Meanwhile, OR gates - the DOO G _45, the output of the counter CNT6 that counts the detection signal of the count detector 31 serving switch SW5 is inputted.

[0043] The counter CNT6 is reset in synchronization with the start of driving the solenoid SoL is released by the output of the gate G ₅₄ to form a solenoid drive start signal at the time the jackpot, the count detector 3 special variation winning apparatus 5
The detection signal from 1 (switch SW5) is counted, the number of winning balls to the special variation winning device 5 is counted, and a predetermined number (for example, 1
When it reaches 0, the output changes to high level. Therefore, the flip-flop FF ₈ is a solenoid SoL.
Is driven for 30 seconds or the number of winning balls reaches 10, whichever comes first, the output / Q changes to the low level, the AND gate G ₄₇ is closed, and the LED Stop blinking of A to LED D. Further, as indicated by the reference numeral, a flip-flop F
Since the output Q of F ₈ is supplied to the AND gate G ₆₃ , blinking of the lamps L ₁ and L ₃ is stopped.

The output of the winning number counter CNT6 is supplied to the decoder driver DD5 to drive the winning number indicator 23 (LED E).
The winning number is displayed on the ED display LED E. This display, when the winning number counter TMC6 is reset by a signal from the flip-flop FF _8, "0"
Return to On the other hand, as described above, the timer counter TMC2 is operated in synchronization with the clock CK4 with the lapse of 30 seconds or the counting of 10 winning numbers, and after 2 seconds,
The time-up signal is output and the flip-flop FF
₈ is reset, the counting operation of the timer counter TMC2 is stopped, and the flip-flop FF
₇ is operated, and by that time, if the flip-flop FF ₆ of the previous stage is operated by the continuation switch SW4 and the output Q changes to the high level, the output Q of the flip-flop FF ₇ of the next stage becomes the high level. To be done.

[0045] Since while the timer counter TMC2 is operating, the output / Q of the flip-flop FF ₈ is set to the low level, the output of the AND gate G ₅₁ is the low level, closing the gate G _54. Therefore, about 2
No solenoid drive signal is output for seconds, so the special variation winning device is temporarily closed. Furthermore, the big hit signal C ₁
Is applied to an AND gate G ₃₈ which is adapted to receive a detection signal from the continuation switch SW4 which is the specific condition constituent detector 32 in the special variation winning device 5, as indicated by the symbol. Thereby, in the big hit, the continuous switch SW4 is turned on, its output Q flip-flop FF ₆ is operated is changed to the high level, it is stored that thereby established continuous conditions, and indicated by reference numeral Thus, the output is supplied to the drivers DR2 and DR4, and the lamps L ₂ and L ₄ are turned on.

At the first occurrence of the big hit, since the output / Q of the flip-flop FF ₄ is at the high level until then, the continuation counter CNT 5 is counted up via the AND gate G ₃₄ and the OR gate G _36. , This makes LED D display "1",
The signal of the switch SW4 causes the flip-flop FF ₄
Is inverted and the output Q changes to high level, so that the gate G ₃₄ is closed. Thus, the continuous second and subsequent, is supplied to the solenoid drive signal continues counter with pulses output from the differentiating circuit DFR6 for detecting a rise through the gate G _35, G ₃₆ (output signal of the gate G ₅₄₎ CNT5 , Is counted up. Accordingly, even if the continuation switch SW4 is turned on more than once during one opening operation, the continuation number is not updated.

By the way, a flip-flop FF ₆ for storing the continuation condition satisfied by the output of the differentiating circuit DFR6.
Since 30 seconds have passed since the solenoid SoL was driven, or the continuation switch SW4 was not turned on by the time the winning number reached 10, the output Q of the flip-flop FF ₆ remained at the low level. Therefore, when the flip-flop FF ₇ is operated by the time-up signal from the timer counter TMC2, the output Q becomes low level, so that the one-shot pulse is output from the differentiation circuit DFR5 that monitors the flip-flop FF ₇ , and the flip-flop FF ₇ is output. FF ₅ is reset and its output Q changes to low level. Its output Q
Is detected by the differentiating circuit DFR4 and a pulse is output to form a jackpot end signal.

Further, when the output Q of the flip-flop FF ₄ is changed to the high level by the detection signal from the continuation switch SW4, the data selector SEL1 is thereby changed.
Is switched to the terminal B side, the value of the continuation counter CNT5 is directly supplied to the decoder driver DD4 instead of the output of the counter CNT4, and the LED display LED
The number of continuations is displayed in D. Further, when the flip-flop FF ₄ is inverted by the signal of the continuation switch SW ₄ , the output / Q is set to the low level, the output of the AND gate G ₄₉ is set to the low level, and thereafter, the LED for displaying the continuation number is displayed. The display LED D, which had been blinking until then, continues to be lit when the continuation switch SW4 is turned on.

In this way, when the opening operation of the special winning device 5 is repeated 9 times by the operation of the continuation switch SW4 to reach the 10th time, the output of the continuation number counter CNT5 is constantly supplied to the sound effect generation circuit SG. Therefore, it is detected that the sound effect generation circuit SG has reached the tenth time, and
A sound effect different from that of the 9th time is generated. In addition, with the occurrence of the 10th sound effect, the output q, which was set to the low level during the big hit, is changed to the high level, and the output of the continuation number counter CNT5 and the flip-flop FF.
_When the output Q of ₄ is input, the output of the NAND gate G ₃₇ becomes high and the AND gate G ₃₈ is closed. Therefore, even if the continuation switch SW4 is turned on thereafter, the output Q of the flip-flop FF ₆ for continuous storage is Does not change to high level. As a result, when the timer counter TMC2 outputs a time-up signal 2 seconds after the end of the opening operation and the flip-flop FF ₇ is operated,
The output of FF ₇ changes to low level, and the differentiation circuit DFR
5 detects this. As a result, the flip-flop FF
₅ is reset, and the jackpot end signal is output from the differentiating circuit DFR4.

As described above, the tenth opening operation is completed, or as described above, the continuation switch SW4 is not turned on during each opening operation (for 30 seconds or until the number reaches ten). When the signal is formed, the flip-flop FF ₂ is reset by the signal, the output Q of the shift register SR 2 is reset, and the output Q ₄ of the signal is changed to the low level. Detects that the jackpot state has disappeared and changes the jackpot signal C ₁ to a low level. This allows the subsequent solenoid S
The driving of oL is stopped. Also, the flip-flops FF ₂ and FF ₄ are reset by the jackpot end signal and returned to the initial state. Moreover, big hit completion signal output from the differentiating circuit DFR4 is for resetting the flip-flop FF ₁ through the OR gate G _9, if there is storage of a particular winning ball in the shift register SR1, the display of the variable display device again The rotation of (LED A to LED D) is started.

An oscillator OSC and a frequency dividing circuit DVD for forming the clocks CK1 to CK5 used in the circuit are provided in the control circuit (a position slightly lower than the center in the drawing). Further, in this embodiment, an injustice detection circuit DTC for monitoring the signal of the switch SW5 which is the count detector 31 is provided, and for example, a ball clogging occurs in the special variation winning device 5 or the switch S
If W5 is removed, switch S
When the ON signal is continuously input for 2 seconds or more from W5, it is determined that the fraudulent state is detected, and the output of the fraud detecting circuit DTC (illegal detection signal) changes to the high level. That is, when an abnormality occurs in the count detector 31 due to a failure such as disconnection, the count detector 31 keeps outputting a predetermined level. On the other hand, even in the case of an abnormality such as a ball clogging, the count detector 31 keeps outputting a signal of the same level as when the winning ball is detected. As described above, the count detector 31 continuously outputs the signal indicating the ON state regardless of whether the abnormality is caused by the failure or the abnormality caused by the ball clogging. However, even if these different kinds of abnormalities are common, the count detector 3 is common in that a certain ON-state signal is continuously output.
By performing an abnormality determination based on the output from 1 being in a predetermined level state (ON state) for a predetermined time, whether an abnormality caused by a failure or an abnormality caused by a ball clogging occurs Judgment is possible.
The fraud detection signals are OR gates G ₄₃ , G ₃₉ , G ₃₂ , and G.
_33, through a _{G 31, G 9, G 21} ~G 24, the flip-flop _{FF 8, FF 5, FF 3} , FF 2, FF 1 and the latch circuit LT ₁ to LT ₄ is reset, has occurred The big hit state or the medium hit state is released to return to the initial state, and the flip-flops FF ₉ and FF ₁₀ are reset to generate the sound effect and the lamps L ₁ , L ₂ and the LED 5
Stop the lighting state of, and LED display LED A ~ L
Turn off EDD.

Furthermore, the change in the fraud detection signal is caused by the differentiating circuit D.
Detected in FR7 a pulse is formed, it is supplied to the preset terminal P of the counter CNT1~CNT4 through the OR gate G ₂₅ ~G _28, counter CNT1~CN
The random numerical value from the random numerical value generating circuit RNG is taken into T4, and the LED indicators LEDA to LEDD are caused to display numbers other than the big hit or the middle hit. It should be noted that, in the above-described embodiment, 3 after the display of the variable display device starts to rotate
If the stop switch SW3 is not pressed within 0 seconds, it will automatically stop, and the random numerical value generation circuit will be used to display numbers other than big hits and medium hits. It is also possible to configure so that the possibility of a big hit or a medium hit is reserved without using the random number generating circuit.

12 to 15 show timing charts of the control operation by the above control circuit. Among these, in the period T ₁ in FIG. 12, the display of the variable display device 4 is rotated and the stop switch SW3 is pressed,
It shows the operation timing when a loss state other than a big hit or a medium hit occurs, and the period T ₂ is automatically stopped by the timer without pressing the stop switch SW3 for 30 seconds after the display starts to rotate. , Shows the operation timing when the lost state occurs. FIG.
A period T ₃ in FIG. ₃ shows an operation timing when the medium hit state occurs, and a period T ₄ shows an operation timing when an irregularity occurs during the medium hit state.

FIG. 14 shows that a big hit occurs, and the continuation switch SW4 is not turned on even during the fourth open state (30 seconds) of the special variation winning device, which causes a so-called puncture state due to time-up. The operation timing in the case of doing is shown. Further, in FIG. 15, the big hit state is 10
Operation timing when the number of times reaches the end and ends (time period T
₅ ) and the operation timing (duration) at the end of the big hit when the continuation switch SW4 is not turned on during the big hit state (third time) when the number of the winning balls to the special variation winning device becomes 10, T ₆ ) and the operation timing (period T ₇ ) when an injustice occurs in the middle of the big hit state (fifth time) are shown.

As described above, in the above-described embodiment, as shown by reference numeral 2 sec in FIGS. 14 and 15, in the big hit state, 30 seconds have passed after the special variation winning device socket 51 was opened, or the number of winning balls was 10. Solenoid 6 reached
After the driving of 6 is stopped, a wait time of 2 seconds is provided respectively, and if the specific condition configuration detector 32 is turned on during this time, the right to continuously open the special variation winning device receiving opening 51 is provided. It is supposed to be granted. Therefore, even if there is a time delay from when the hit ball is won in the special variable winning device receiving port 51 to when it is detected when the special jackpot is generated and the special variable winning device 5 is opened, 2
Since the specific condition configuration detector 32 is surely turned on if there is a second, even if the hit ball that has won the prize enters the specific condition configuration section entrance constituted by the guide plate 52c while the receiving opening is closing, it continues. Rights are granted. Therefore, the player is not dissatisfied and there is no risk of trouble with the game shop. Further, if there is a waiting time of 2 seconds each time, the processing of the winning balls in the rearranging room 58 is considerably advanced, and the prize balls are dispensed in the prize ball dispensing device operated in association with this.
