It becomes difficult to win a pachinko ball P to. This is because the pachinko balls P are flipped by the adjusting nails 109a and 109b, and the V-pocket winning port 66 wins the winning ports 64a or 64b on both sides with a high probability. On the contrary, as shown in FIG. 7, when the adjusting nails 109a and 109b are adjusted so that both ends thereof are separated from each other, it becomes easy to win the pachinko ball P to the V pocket winning port 66. Adjusting nails 109a, 109b
This kind of action is similar to the action of a normal obstacle nail provided on the game board 14, but since the adjusting nails 109a and 109b are provided directly above the V pocket winning port 66, the V pocket winning port 66 There is an effect that the winning probability of the pachinko ball can be adjusted to a probability within a desired range very easily.

Since the adjusting nails 109a and 109b are erected on the mounting substrate 52, which is generally a plastic molded substrate, the mounting substrate 52 may be cracked or the like during the adjustment work. In order to eliminate such a fear, the following measures should be taken. For example, the adjusting nails 109a and 109b are preliminarily loosely bent nails and have threaded nails at their rear ends, and the adjusting nails 109a and 109b are rotated by rotating the nails in a desired direction.
A desired state of being relatively wide or relatively narrow between b is set. After that, the nut may be screwed and fixed to the thread cut at the rear end.

FIG. 10 is a vertical cross-sectional view of the central portion of FIG. 9, showing how the pachinko balls P ₅ are locked.

As shown in FIG. 5, when the swing head 98 is horizontal,
Pachinko balls P ₁ or P ₂ dropped on the swing head 98
Are distributed right and left by the swing head 98, and fall above the winning opening 64a or 64b. Therefore, the probability of winning of these pachinko balls P ₁ and P _{2 in} the V pocket winning port 66 is low, and the probability of winning in the winning port 64a or 64b is high. Further, the pachinko ball P _{3 that} has dropped onto the cover member 96 (or 94) is guided along the peripheral surface of the cover member 96, and is rotated around the back of the mounting substrate 52 by the fixing plate 92 (see FIG. 4). It is guided to the winning opening 64a or 64b. Therefore, the V-pocket winning hole 66 cannot be won. In this way, when the swing head 98 is in the horizontal state, the pachinko balls are distributed to the left and right by the swing head 98,
Since it is hard to drop right above the pocket winning opening 66, the probability of winning a pachinko ball into the V pocket winning opening 66 is low.

Next, the case where the swing head 98 swings downward will be described. In this case, particularly, the case where the swing head 98 swings downward and the opening / closing blades 68a, 68b are in the open state will be described.

As shown in FIGS. 9 and 10, when the swing head 98 swings downward and the opening / closing blade pieces 68a, 68b are in the open state, the swing head 98 and the opening / closing blade pieces 68a or 68b are opened.
The pachinko ball P ₄ or P ₅ is temporarily locked by the gap between the inner end (lower edge) of b and the inner glass plate 128b.
Then, when the opening / closing wings 68a, 68b are closed from this state, the pachinko balls P that have been locked fall above the V pocket winning opening 66. Therefore, the winning probability of the dropped pachinko ball P to the V pocket winning port 66 is high.

From the above basic operation, by selecting the opening timing of the open / close blades 68a, 68b and the timing at which the swing head 98 swings downward, as shown in FIG. 9 or FIG. ₄ and P ₅ open / close wing pieces 68a, 68
It will be understood that it is possible to lock by the b, the swing head 98 and the glass plate 128b, and it is possible to adjust the winning probability of the pachinko ball to the V pocket winning port 66.

As described above, this embodiment can adjust the winning probability of the pachinko ball to the V pocket winning port 66 by combining the two winning probability adjusting members of the swing head 98 and the adjusting nails 109a and 109b. It is characterized by doing so.

46 is set. The n-ary counter 246 is the frequency divider 2
A counter operation is performed based on the output P0 of 12 and the holding circuit 22 is operated when the count value becomes "18", for example.
The reset pulse is derived in the step 6. Due to the action of the n-ary counter 246, the opening / closing blade pieces 68a, 68b.
Is opened and closed a maximum of 18 times and is in the post-closed state.

The number of pachinko balls that have won the variable winning ball device 16 is detected by the winning ball number detection switch 44 (see FIGS. 2 and 14), and the count switch 248 and the differentiation circuit 2 are detected.
It is provided via 50 as the up input of the counter 252. The counter 252 is a counter that is reset by the output of the V winning ball detection circuit 224, and is reset each time a pachinko ball is won into the V pocket winning port 66. Then, the counter 252 holds the holding circuit 22 when the count value becomes “10”, for example.
A reset signal is given to 6. Therefore, when the number of winning pachinko balls to the variable winning ball device 16 becomes 10, the holding circuit 226 is reset and the opening / closing blade piece 68 is reset.
The opening and closing of a and 68b are completed, and the closed state is established.

Next, the operation timings of the solenoid 82 and the solenoid 104 will be described in detail with reference to FIGS. 14 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. Timing adjustment circuit 22
Reference numeral 8 is composed of, for example, a flip-flop, and based on the set signal from the holding circuit 226, the frequency divider 21
It is a circuit that gives a signal to the frequency divider 212 in order to adjust the derivation timing of the output P1 and the output P4 of the second output. The output of the timing adjustment circuit 228 is simultaneously output from the OR gate 2
30 to the solenoid control circuit 232, the output of which is applied to the driver 234 to control the solenoid 10
4 is driven. 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 234 via the 8, OR gate 230 and the solenoid control circuit 232.

The set output of the holding circuit 226 is also the delay circuit 236.
Is delayed by a predetermined time and is given to one input terminal of a 2-input AND gate 210 via an 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 frequency divider 2 for which timing adjustment has been performed
The 12 outputs P1 and P4 are started to be derived. Therefore, the AND gate 210 outputs the output of the delay circuit 236,
A logical product output with the output P1 of the frequency divider 212 is derived, the driver 214 is driven, and the solenoid 82 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, which is timed with the output P1, is the AND gate 238.
Is ANDed 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 rocking 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, between the opening / closing timing of the opening / closing wing pieces 68a, 68b of the variable winning ball device 16 and the swing timing of the swing head 98 (see FIG. 5). , Have a certain relationship. That is,
As shown in FIG. 15, the timing at the start of driving is adjusted and the opening / closing blade pieces 68a, 68b are opened (solenoid 82).
ON) start timing and the timing at which the swing head 98 swings upward (OFF of the solenoid 104) are combined, and both are turned on / off and turned off / off at 0.74 second and 0.71 second intervals, respectively. It is supposed to be turned on. And the on timing of both is the same,
For example, it is set to be the 12th ON time.

The reason for this is as follows. As described above, the open / close blades 68a, 68b are in the open state and the swing head 98
When is swinging downward, the pachinko balls are easily locked by both. Then, as a result, the winning probability of the pachinko ball to the V pocket winning port 66 increases. On the other hand, immediately after the opening / closing blades 68a, 68b start opening and closing, and the pachinko balls easily enter the V pocket winning opening 66, the opening / closing blades 68a, 68b at the time of winning. The opening / closing operation or the number of times of opening / closing will be updated. That is, the opening / closing wing piece 68 of the variable winning ball device 16
Even if the opening and closing of a and 68b are repeated, a situation occurs in which a pachinko ball easily wins the V winning opening 66 immediately after the repetition of the opening and closing, and a prize ball cannot be obtained sufficiently during opening and closing of the opening and closing blades 68a and 68b. It can happen. Therefore, in this embodiment, the timing at which the opening / closing blade pieces 68a, 68b are opened and the timing at which the swing head 98 swings downward are exactly the same when the opening / closing blade pieces 68a, 68b are opened for the twelfth time, for example. Are associated with.
As a result, during the repeated opening / closing of the opening / closing blades 68a and 68b, the pachinko balls are not likely to win the V pocket winning opening at first, but the V pocket winning opening 6 is halfway through.
It is a pachinko ball game machine with a high degree of appeal to the player, in which it is easy to win a pachinko ball to 6 and the payout rate is improved.

16 to 19 are views showing another embodiment of the variable winning ball device. The feature of the variable winning ball device 160 shown in FIGS. 16 to 19 is that the variable winning ball device 1 described above is used.
The rotating head 162 is provided in place of the swing head 98, which is an example of a pachinko ball winning probability adjusting member in FIG.

The rotary head 162 includes short blades 164a and 164b protruding left and right as shown in FIGS. 16 and 18. One surface 166a, 16 of the short wings 164a, 164b
6b is a variable winning ball device 160, as shown in FIG.
There is a gentle slope from the front to the rear. Therefore, as shown in FIG. 17, when one surface 166a, 166b of the rotary head 162 is located on the upper side, the pachinko ball P dropped on the rotary head 162 is guided to the rear of the variable winning ball device 160. , With a relatively high probability of winning in the regular winning openings 64a, 64b.

On the other hand, the rotary head 162 rotates, and FIG.
As shown in FIG. 9, the opposite occurs when the other surface of the short blades 164a, 164b faces upward. That is, the other surfaces 168a, 16b of the short wings 164a, 164b
As shown in FIG. 19, 8b is a variable winning ball device 160.
It is sloped from the rear to the front. Therefore, when the rotary head 162 is in the state shown in FIG. 18 and FIG. 19, the pachinko balls P falling from there are the short blades 164 a of the rotary head 162.
It is guided to the front side along 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 into the V pocket winning port 66 within a desired range. The swing head 98, the solenoid 104, the rotating shaft 100, the connecting link 1
02 or the rotary head 162 constitutes a winning probability changing means for changing the winning probability of hitting a ball in the specific winning area. As described above, the winning probability changing means ensures that the winning probability is higher at the stage when the end of the first state is closer than at the initial stage when the variable winning ball device is in the first state. It has the function of changing. Even if the variable winning ball apparatus is in a state in which the winning state has increased since the first state has passed halfway through, the hitting ball is engaged by the open / close wing pieces 68a, 68b, the swing head 98, and the rotary head 162. If it is not stopped, the actual winning probability will not increase. In other words, the state that the winning probability is increasing does not mean that the winning probability is always high in any case, but the winning probability is statistically increased as a result of playing the game for a long time. The state of being.
