64 is reset. That is, the variable winning ball device 16
When a pachinko ball is won in the V pocket winning opening 60 while the opening / closing blades 66a, 66b are opening / closing, the opening / closing blades 66a, 66b are opened and closed at intervals of about 0.8 seconds from the time of winning.
Repeated eight times, during which a big hit situation occurs where a maximum of 10 pachinko balls can be won. Then, if there is a pachinko ball that has won the V-pocket winning opening 60 among the winning pachinko balls, the above-mentioned opening / closing wing piece 66 is further started from that point.
The value of opening and closing a, 66b 18 times or winning 10 pieces of pachinko balls is added once more, and the value is repeated up to 8 times. When it is repeated up to eight times, the prize state prohibiting circuit 178 is operated by the output of the octal counter 176, and further repetition is prevented. The winning ball counter 38, the differentiating circuit 180, and the counter 182 are for that purpose. In this case, how many times the player has been in the prize state,
That is, how many pachinko balls are in the V-pocket winning hole 60 can be known by the number of blinks of the central LED 123.

In the above embodiment, the output of the predetermined information changing means 122 is displayed on the digital display 74 in the normal game state, and when the specific game state is detected, the output of the predetermined information changing circuit 122 is displayed.

The variable winning ball device 16 is opened and closed for a value based on the displayed value, for example, a time proportional to the displayed value so that the predetermined value counted at 34 is displayed.
As described above, instead of using the digital display 74 as a means for displaying the value provided when the game is in the specific game state, a plurality of display lamps 184a, 184 as shown in FIG.
It is also possible to adopt a configuration in which b and 186 are provided. Then, in the normal gaming state, a plurality of display lamps 184a, 184b, 1 based on the output of the predetermined information change circuit 122.
86 is blinked cyclically or randomly and one of the predetermined display lamps 184a, 184b or 186 specified by the ring counter 134 is turned on based on the detection of the specific game state. Then, the value to be given can be changed according to the display of the lit display lamp. For example, when the display lamps 184a and 184b are turned on, the variable winning ball device 16 is opened and closed for a relatively short time, and when the display lamp 186 is turned on, the variable winning ball device 16 is opened and closed for a relatively long time. Can be

Further, in the above-mentioned embodiment, when the pachinko ball winning the V-pocket winning hole 60 is detected, the variable winning ball device 16 is uniformly set to 18 by the n-ary counter 166.
The number of pachinko balls that can be opened and closed or variable prize balls 16 is 10
The value of individual winning is given, but the value given by the ring counter 134 is given without uniformly setting the value given when a pachinko ball wins the V pocket winning opening 60, as described above. It can also be configured to do so. Furthermore, the prize ball detection switch 61
In the case where the ball detected in step 1 is detected again by the detection switch, the big hit state may be generated only after being detected by the prize ball detection switch 61 and detected by the detection switch.

FIG. 13 is a circuit block diagram showing another configuration of the control circuit of the pachinko gaming machine. Next, the operation when the pachinko gaming machine of FIGS. 1 to 10 is controlled based on the control circuit of FIG. 13 will be described.

In the control circuit of FIG. 13, the starting winning opening 18
The specific gaming state is detected in response to the pachinko balls winning all the winning openings a, 18b, 18c. That is, when all of the winning ball detectors 19a, 19b, 19c detect the winning of a pachinko ball, the holding circuits 202, 20 configured by flip-flops, for example.
The output of 4,206 becomes high level, the output of the AND gate 208 which constitutes the specific game state detecting means becomes high level, and the high level output is derived from the holding circuit 210 accordingly.

When the output of the holding circuit 210 becomes high level, the AND gate 211 is activated. Therefore,
The output P2 from the frequency divider, which is obtained by dividing the output of the clock oscillator 224, is given to the solenoid 90 via the driver 215. Therefore, the solenoid 90 is turned on / off at a predetermined cycle.
It is turned off, and the opening / closing blades 66a, 66 of the variable winning ball device 16 are turned off.
b is opened and closed. That is, the variable winning ball device 16 is brought into the first state, which is advantageous for the player. In addition, the holding circuit 2
The output of 10 is given to the sound effect generation circuit 156, the motor drive circuit 174, and the display drive circuit 217. Therefore, the speaker 28 is sounded, a sound effect is output, the motor 106 is rotated, and the landing gear 94 is repeatedly lowered and raised. In addition, the display drive circuit 217 is used in the frequency divider 2
Operates in response to a divided output P1 of 13 and produces a 7-star lamp 1
The light emitting diodes constituting 23 are sequentially blinked.

On the other hand, in the normal game state which is not the specific game state, the display of the digital display 74 is changed by receiving the output of the predetermined information changing circuit 212. That is, the ever-changing information output from the predetermined information changing circuit 212 is decoded by the decoder 214 and displayed on the digital display 74.

On the other hand, in the specific game state, the high level output is derived from the holding circuit 210 as described above. This output is inverted by the inverter 126 and given to the predetermined information changing circuit 212. The predetermined information change circuit 212 derives the output when the high level output is derived from the inverter 216, but does not derive the output when the output of the inverter 216 becomes the low level. Therefore, the predetermined information changing circuit 212 does not operate in the specific game state.

On the other hand, the high level signal from the holding circuit 210 is the ring counter 22 in the predetermined value changing means 218.
Given to 0. The predetermined value change means 218 operates based on the output from the setting circuit 222 for setting the value and the clock oscillator 224, and the predetermined value change control circuit 226 for changing the value set by the predetermined circuit 222, and the predetermined value change. A ring counter 220 whose count value changes cyclically in response to the output of the control circuit 226. Then, the ring counter 220 stops its counting operation when the output of the holding circuit 210 becomes high level, and outputs a predetermined numerical value. The output of the ring counter 220 is decoded by the decoder 214,
It is displayed on the digital display 74. Therefore, in the normal game state, the predetermined information changing circuit 2 is displayed on the segment display 74.
The output of 12 is displayed, and in the specific game state, instead of the output of the predetermined information changing circuit 212, the count output of the ring counter 220 is displayed.

The output of the ring counter 220 is given to the down counter 228 and the down counter 228 is supplied.
Is set to the count value of the ring counter 220.
The output of the winning ball detector 38 is differentiated in the down counter 228 by the differentiating circuit 230, and is given to the down counter 228 via the AND gate 232 which is activated by the output of the holding circuit 210. Down counter 2
At 28, the count value is decremented by 1 each time there is an input pulse from the winning ball detector 38, and when the count value becomes 0, a reset signal is derived to the reset pulse generation circuit 234. In response, the reset pulse generation circuit 234 outputs a reset pulse, and the holding circuits 202, 204, 206.
And 210 are reset and each output goes low. Therefore, the solenoid 90 is turned off, and the variable winning ball device 16 is closed.

As described above, in this embodiment, the count value counted by the ring counter 220, in other words, an arbitrary number selected at the time of entering the specific game state, is a value given in the specific game state, that is, This is a configuration that is set as the number of winning balls that can be won in the specific game state. Therefore, the number of winning prizes that can be set for each specific game state changes with chance,
The control in the specific game state of the variable winning ball device is not monotonous, and the pachinko gaming machine can be enjoyed by the player.

The holding circuits 202, 204, 206
Is the output of the starting winning ball detection switches 19a, 19b, 19c after a predetermined time has elapsed (the predetermined time is respectively the timers 236, 238, 240 and the differentiating circuits 242, 2).
44 and 246, and is output) or is reset according to the output of the clear button 248. The clear button 248 is provided, for example, on the back surface or front surface of the pachinko gaming machine 10, and is operated by a staff member or a player. Therefore, when a pachinko ball is won at a certain starting winning opening (for example, the starting winning opening 18a), the output of the starting winning ball detection switch 19a becomes high level and the high level output is derived from the holding circuit 202, but after a predetermined time has elapsed. An output is derived from the timer 236, a reset pulse is applied to the holding circuit 202, and the output of the holding circuit 202 is set to a low level. Therefore, the player sets the output of the holding circuits 202, 204, 206 to a high level and puts it in a specific game state unless he or she wins the pachinko balls to the three starting winning openings 18a, 18b, 18c within a predetermined time. You cannot do it.

Further, in this embodiment, the holding circuit 202,
The outputs of 204 and 206 are the display drive circuits 250 and 25.
2,254, pilot lights 256,25
8, 260 are lit. Therefore,
The player can know which of the starting winning openings the pachinko ball has won by checking whether the pilot lamps 256, 258, 260 are on or off, which has the effect of facilitating a game strategy. There is. The pilot lamps 256, 258, 260 are provided on the game board 14 or on the surface of the pachinko gaming machine 10 at locations easily visible to the player.

FIG. 14 is a block diagram showing the configuration of a control circuit according to still another embodiment of the present invention. This control circuit block diagram shows a variable winning ball device, for example, a variable winning ball device and a variable display device for determining a specific game state as described in another patent application Japanese Patent Application No. 59-280547 of the present applicant. It is a block diagram of a control circuit for controlling.

Referring to FIG. 14, when the winning ball detector 262 detects the winning of a pachinko ball in a predetermined area, a signal is given to the drive circuit 266 via the OR gate 264. In response, the drive circuit 266 drives the motor 268.
And the solenoids 270a, 270b, 270c are driven, and the display of the variable display device is changed. The drive circuit 266 stops driving the motor 268 and the solenoids 270a, 270b, 270c by the output of the timer 272 or the stop button 274 which is operated by the output of the OR gate 264 and derives the output after a predetermined time elapses.
At this time, the combination of the display stopped by the drive circuit 266 is determined by the display state determination means 276, and when the specific game state is reached, the drive control circuit 278 is driven, the solenoid 280 is turned on, and the variable winning a prize not shown. The ball device is opened.

On the other hand, in the digital display 280 for displaying predetermined numerical information, the data output from the predetermined value change control means 282 is decoded by the decoder driver 284, and the output is displayed. Then, when there is an output from the winning ball detector 262, the flip-flop 286 is set, and the AND gate 288 is activated by the set output. Therefore, the oscillation output of the clock oscillator 290 is given to the predetermined value change control means 282, the way of the change is changed, and the output of the means 282 is displayed on the digital display 280. After that, the flip-flop 286 is set by the judgment output of the display state judging means 276, and the output given from the AND gate 288 to the predetermined value change control circuit 282 disappears. Then, the count value of the ring counter 292 at that time is displayed on the digital display 280, and the count value is set in the down counter 294. The value displayed on the digital display 280 and set in the down counter 294 is used in the specific gaming state.

That is, in the specific game state, the solenoid 280 is turned on by the drive control circuit 278 as described above. The variable winning ball device is opened. Further, the flip-flop 296 is set by the specific game state determination output of the display state determination means 276, and the set output is given to the timer 302 via the OR gate 300. Then, the timer 302 starts operating, the change signal of the timer 302 is differentiated by the differentiating circuit 304, and the down counter 294.
And the count value is subtracted according to the time.
When the count value of the down counter 294 becomes 0, it is detected by the 0 detection circuit 312, the output of the predetermined value addition completion detection circuit 314 is derived, and the inhibition signal is given to the drive control circuit 278. .. Therefore, the drive control circuit 278 turns off the solenoid 280, and the variable winning ball device is closed.

If a pachinko ball is won in a specific winning area of the winning area, that is, a so-called V-pocket winning opening while the variable winning ball device is opened, the winning is detected by the detection switch 31.
Detected at 6. Then, the open state of the variable winning ball device is maintained as follows. That is, the flip-flop 320 is set by the detection switch 316, and the output of the AND gate 310 is given to the timer 302 via the OR gate 300. Therefore, the timer 302 is reset and starts counting the predetermined time again. Therefore,
Similar to the above-described operation, the variable winning ball device is opened for a time proportional to the predetermined numerical data set by the down counter 294. Therefore, the set output of the flip-flop 320 is provided to the predetermined value change control circuit 282. This output resets the down counter 294.
