The opening / closing drive solenoid 82 of 8a and 68b is turned on / off. The output of the holding circuit 226 is also given to the AND gate 238 and the driver 234 via the OR gate 230 and the solenoid control circuit 232, whereby the swing head 98 driving solenoid 104 is turned on / off.

Further, the output of holding circuit 226 is inverted by inverter 240 and applied to lamp 119 (see FIG. 5) via NOR gate group 242 and add gate group 244.

Further, n is output by the holding circuit 226.
The advance counter 246 is set. n-ary counter 246
Performs a counting operation based on the output P0 of the frequency divider 212, and derives a reset pulse to the holding circuit 226 when the count value reaches "18", for example. Due to the action of the n-ary counter 246, the opening / closing blade 6
8a and 68b are opened and closed a maximum of 18 times to be in the post-closed state.

The number of pachinko balls that have won the variable winning ball device 16 is determined by the number of winning ball detection switch 44 (see FIGS. 2 and 14).
Detected by the counter) and is given as an up input of the counter 252 via the count switch 248 and the differentiating circuit 250. The counter 252 is a V winning ball detection circuit 2
V is a counter that is reset by the output of 24
It is adapted to be reset each time a pachinko ball enters the pocket winning opening 66. Then, the counter 252 gives a reset signal to the holding circuit 226 when the count value reaches "10", for example. Therefore, when the total number of the pachinko balls to the variable winning ball device 16 reaches 10, the holding circuit 226 is reset and the opening / closing of the opening / closing blades 68a and 68b is completed, and the closed state is established.

Next, the operation timings of the solenoid 8 and the solenoid 104 will be described in detail with reference to FIGS. 4 and 15. The holding circuit 226 is set based on the output of the V winning ball detection circuit 224, and the set output is given to the timing adjustment circuit 228. The timing adjustment circuit 228 is configured by, for example, a flip-flop, and adjusts the derivation timing of the output P1 and the output P4 of the frequency divider 212 based on the set signal from the holding circuit 226. It is a circuit that gives a signal to. The output of the timing adjustment circuit 228 is simultaneously given to the solenoid control circuit 232 via the OR gate 230, and the output thereof is given to the driver 234 to drive the solenoid 104. When the holding circuit 226 is initially set, as shown in FIG.
The drive solenoid 104 of the swing head 98 is continuously turned on by a signal provided to the driver 434 via the 28, the OR gate 230, and the solenoid control circuit 232.

The set output of the holding circuit 226 is delayed for a predetermined time by the delay circuit 236, and is applied to one input terminal of the 2-input AND gate 210 via the OR gate 208. At the same time, the output of the timing adjustment circuit 228 is stopped by the output of the delay circuit 236. In response to the output of the timing adjustment circuit 228 being stopped and inverted to a low level, the outputs P1 and P4 of the timing-adjusted frequency divider 212 are started to be derived. Therefore, the AND gate 210 includes the delay circuit 23.
6 and the output P1 of the frequency divider 212 are derived, the driver 214 is driven, and the solenoid 82 is driven.
Is turned on / off at the timing shown in FIG. That is, the solenoid 82 is opened and closed in a cycle of 0.74 seconds, for example. The state in which this opening and closing is repeated is the first state in which the variable winning ball device 16 is advantageous to the player.

On the other hand, the output P4 of the frequency divider 212,
The output P4, which is timed with the output P1, is ANDed by the AND gate 238 and is given to the driver 234 via the OR gate 230 and the solenoid control circuit 232. Therefore, as shown in FIG. 15, the solenoid 104 of the oscillating head 98 starts to be turned on / off repeatedly at intervals of 0.71 seconds, for example.

By the way, as shown in FIG. 15, in this embodiment, the opening / closing blades 68a, 68b of the variable winning ball device 16 are arranged.
There is a certain relationship between the opening / closing timing of the above and the swing timing of the swing head 98 (see FIG. 5).
That is, as shown in FIG. 15, the timing at the start of driving is adjusted so that the opening / closing blades 68a and 68b start opening (the solenoid 82 is turned on) and the swing head 98 swings upward (the solenoid 104). Off) and both are 0.74 seconds and 0.
It is designed to be turned on / off and turned off / on every 71 seconds. Then, the ON timings of the both are matched with each other, for example, at the 12th ON time.

The reason for this is as follows. As described above, when the open / close blades 68a and 68b are opened and the swing head 98 is swinging downward, the pachinko balls are easily locked by both. And thereby V
The probability of winning a pachinko ball into the pocket winning opening 66 increases. On the other hand, immediately after the opening / closing blades 68a, 68b start to open and close, and the pachinko balls easily enter the V-pocket winning opening 66, the opening / closing blades 68a, 68b at the time of winning the prize. The opening / closing operation or the number of times of opening / closing is updated. That is, even if the opening / closing wings 68a, 68b of the variable winning ball device 16 start to be repeatedly opened and closed, a situation occurs in which a pachinko ball easily wins the V pocket winning opening 66 immediately after the start of the repetition, and the opening / closing wings 68a, 68b. During the repeated opening and closing of, it may happen that you cannot get enough prize balls. Therefore, in this embodiment, the opening / closing blade pieces 68a, 68b are used.
Is associated with the timing at which the swing head 98 swings downward so that the opening / closing blade pieces 68a and 68b are exactly coincident with each other when they are opened for the twelfth time. Thereby, the opening / closing wings 68a, 68
During the repeated opening and closing of b, the pachinko ball does not easily win the V pocket winning opening at the beginning, but V is too midway.
Pachinko balls are easy to win in the pocket winning opening 66,
It is a pachinko gaming machine that has a high appeal rate for players with an improved payout rate. Also, the swing head 9
8 swings downward and the opening and closing blade pieces 68a, 68
The opening timing of b may be matched on the condition that a predetermined number (eg, 7) of hit balls have been won in the variable winning ball device.

16 to 19 are diagrams showing another embodiment of the variable winning ball device. The feature of the variable winning ball device 160 shown in FIG. 16 to FIG. 19 is that a rotating head 162 is provided instead of the swing head 98 which is an example of the winning probability adjusting member for the pachinko balls in the variable winning ball device 16 described above. is there.

As shown in FIG. 17, one surface 166a, 166b of each of the short wings 164a, 164b is provided with an inclination that gently decreases from the front to the rear of the variable winning ball device 160. Therefore, as shown in FIG. 17, one surface 166a, 166b of the rotary head 162 is formed.
In the state where is located on the upper side, the pachinko balls P dropped on the rotary head 162 are guided to the rear of the variable winning ball device 160, and win the normal winning holes 64a and 64b with a relatively high probability.

On the other hand, the rotary head 162 rotates, and FIG.
And as shown in FIG. 19, the opposite occurs when the other surface of the short blades 164a, 164b faces upward.
That is, the other surface 168 of the short wings 164a, 164b
As shown in FIG. 19, the a and 168b are inclined so as to descend from the rear to the front of the variable winning ball device 160. Therefore, the rotary head 162 is
In the state shown in FIG. 19 and FIG. 19, the pachinko balls P falling from there are the short blades 164 of the rotary head 162.
It is guided to the front side along a and 164b. Then, at the moment when the opening / closing blades 68a, 68b are closed, the pachinko balls fall downward, and the V-pocket winning port 66 wins with a relatively high probability.

Therefore, by adjusting the direction of the rotary head 162, it is possible to adjust the winning probability of the pachinko balls to the V pocket winning port 66 within a desired range.
