The AND gate 118 also includes the output terminal Q+@Qt of the common binary counter 67 shown in FIG.
The output from Qs is input, and this AND gate 118 outputs H when the count value of the binary counter 67 reaches 7. The AND gate 119 also includes an output terminal Q of a common binary counter 74 shown in FIG. , Qs+ are input, and this AND gate 119 is set to 1 after the binary counter 74 starts outputting.
After 9.2 seconds, that is, when the solenoid 17 is driven 12 times, an H signal is output. Or game) 120
The output signal from the NOR gate 63 of the latch circuit 62 and the output signal from the AND gates 118 and 119 are respectively input to the latch circuit 62. The output signal from the OR gate 120 and the feedback output signal from the NOR gate 123 are input to the NOR gate 122 . The output signal of the NOR gate 122 is inputted to one input terminal of the NOR gate 123 via a delay circuit, and the power-on reset signal PR is inputted to the other input terminal! It's becoming a sea urchin.

Therefore, the trigger pulse output circuit 121 says that the 10 count value became "7" during 188 rotations.

When the solenoid 17 is driven 12 times during 188 rotations, an H clock pulse is output to the latch circuit 117, and when the power-on reset signal PR is output, its output is prohibited. There is. The output terminal Q of the latch circuit 117 is connected to the other input terminal of the OR gate 116b, and the output terminal of the OR gate 116b is connected to the fill input terminal of the electromagnet 138 via the electromagnet drive transistor 114. The reset terminal R of the latch circuit 117 is connected to the output terminal of the OR gate 81 shown in FIG. 12, and is reset when the latch circuit 62 is latched.

Another example of the circuit configuration described above operates according to the flowcharts shown in FIGS. 14 and 15.

As shown in Figure 2: When a pachinko ball flies into either of the two winning holes 3, first.

It starts with the closing of the one-time action winning ball switch 53, and when the guide vane 13 opens and closes only once, the one-time action switch head rotation input circuit 115 is activated at the same time, so the one-time head rotation timing circuit 113 is activated, and the electromagnet 138 is excited, and the head 9 rotates in the same manner as in the example described above, but this rotation is performed at 1.
After 5 seconds, the output terminal Qs of the binary counter 74 becomes H (high) and the latte circuit 116 is reset, so that the part 9 is turned on by one-quarter rotation. Then, when the pachinko ball jumps into the first winning hole 3 again, the head 9 further rotates by a quarter of a rotation, and as shown in FIG. Although the position of the head 9 is omitted, each time a pachinko ball jumps into the first winning hole 3, it makes a quarter rotation. In this way, the player is provided with a different gaming experience from the example described above.

In another aspect, when the pachinko ball jumps into the big winning hole 11, the %188 rotating winning ball switch 59 closes, and the guide blade 13 performs 18 opening/closing operations, of which the guiding blade 13 opens/closes 12 times. when you perform an action, or
When 7 pachinko balls fly into the grand prize opening 11,
The head rotation timing circuit 113 operates and the electromagnet 13
8 is excited and the head 9 is continuously rotated. This is because, in addition to the quarter rotation of the head 9 mentioned above, the rotation of the head 9, as shown in FIG. It has a gameplay feature that makes it easier or harder to enter.

(Effects of the Invention) From the above, the winning device for a pachinko machine of the present invention, in addition to the opening/closing operation of the guide blades, provides a head on the vertical center line held by the guide blades and extends from the head. The head can be quickly rotated and stopped by making the rotating shaft a constantly rotating motor shaft, which can be freely engaged and disengaged by a magnetic clutch mechanism depending on the winning result. This allows players to enjoy a wide range of interesting games.-In contrast to conventional games that use a motor to rotate the head, the rotation axis of the head and the motor shaft The engaging and disengaging operations are quick, giving players many opportunities to win prizes. However, since waste caused by delayed rotation operations when starting and stopping the motor as in the prior art can be eliminated, the conditions can be easily set.
