Next, the control I operation of the pachinko gaming machine 10 will be explained with reference mainly to FIGS. 14 and 15, and also to FIGS. 1 to 13 as necessary.

The pachinko balls fired by the player enter the starting prize opening 22, 24 or 26 (see FIG. 1). For example, a pachinko ball enters the starting winning hole 22.

Then, the winning ball detection switch 46 (FIGS. 2 and 14)
(see figure) is turned on, and accordingly, an output is derived from the winning detection circuit 200 via the OR gate 202 to the holding circuit 204. The holding circuit 204 is a circuit that holds the input signal until a reset signal from the reset pulse generating circuit 206 is received, and the output of the holding circuit 204 is applied to one input terminal of an AND gate 210 via an OR gate 208. The AND gate 210 is a two-person gate, and the P1 output from the frequency divider 212 is applied to the other input terminal. The output of the AND gate 210 is applied via a driver 214 to a driving solenoid 82 for opening/closing blades 68a and 68b (see FIG. 3).

Therefore, the solenoid 82 outputs the output P1 of the frequency divider 212.
Opening and closing operations are performed periodically. Further, the output of the holding circuit 204 is provided to a sound effect generating circuit 218 via an OR gate 216. Therefore, the speaker 36 (see FIG. 1) outputs a sound effect based on the output of the holding circuit 204. At the same time, the output of the holding circuit 204 is applied to one input terminal of the two-person AND gate 220, and gate 2
The output P2 of the frequency divider 212 is applied to the other input terminal of the frequency divider 212. Therefore, lamps 150 and 156 connected to the output terminal of AND gate 220 output P2
It flashes on and off in a cycle that adds to the atmosphere of the game.

The holding circuit 204 is given a reset signal from the reset pulse generation circuit 206 as described above. The reset pulse generation circuit 206 is supplied with the output PO of the frequency divider 212 (an output that is equal in cycle to the output P1 and whose timing is shifted), and the reset pulse generation circuit 206 generates a reset pulse based on this output PO. will occur. In this embodiment, when a pachinko ball enters the starting input port 22 or 26, the opening/closing wings 68a and 68b are opened and closed once, that is, the solenoid 82 is turned on once in a predetermined cycle. , the output PO1 of the frequency dividing circuit 212
A reset pulse is derived every cycle. In addition, when a pachinko ball wins in the starting winning hole 24, that is, when the starting winning ball detection switch 48 is turned on and the output is derived from the winning detection circuit 222, the output of the holding circuit 202 is transferred to the opening/closing plates 68a, 68b. The reset pulse generation circuit 206 is switched based on the output of the winning detection circuit 222 so that the pulse is generated while the pulse is opened and closed twice.
The reset pulse derivation cycle is designed to be improved.

A pachinko ball enters the starting winning hole 22 or 26 or 24, and while the opening/closing wings 68a, 68b are opened and closed once or twice, the pachinko ball flies into the variable winning ball device 16, and ■pocket winning hole Suppose you win 66. Then, the winning is detected by the V winning ball detection switch 42 (see FIGS. 2 and 14), and the winning ball detection circuit 22
The output is derived from 4. Accordingly, the holding circuit 226 is set, and its set output is delayed for a predetermined time by the delay circuit 236, and is applied to the driver 214 via the OR gate 208 and the AND gate 210, and the opening/closing π piece 68a,
The opening/closing driving solenoid 82 of 68b is turned on/off. The output of the holding circuit 226 is also connected to an AND gate 238
, is applied to the driver 234 via the OR gate 230 and the solenoid control circuit 232, thereby turning on/off the swinging head 98 driving solenoid 104.

Further, the output of the holding circuit 226 is inverted by an inverter 240 to form a NOR gate group 242 and an OR gate group 244.

is opened and closed a maximum of 18 times and enters the post-open state.

The reason why only one pachinko ball is entered into the variable winning ball device 16 is by the number of winning balls detection switch 44 (see Fig. 2 and Fig. 14).
count switch 248 . It is provided as an up input to a counter 252 via a differentiating circuit 250. The counter 252 is a counter that is reset by the output of the winning ball detection circuit 224, and is reset each time a pachinko ball enters the pocket winning opening 66. Then, when the count value of the counter 252 reaches, for example, "10".

A reset signal is given to the holding circuit 226. therefore,
■The number of winning pachinko balls in the pocket prize opening 66 is 10.
When the opening/closing π pieces 68a, 68b are opened/closed, the holding circuit 226 is reset, and the opening/closing π pieces 68a, 68b are finished opening and closing, and the opening/closing π pieces 68a, 68b are brought into an open state.

Next, the operation timing of the solenoid 82 and the solenoid 108 will be described in detail with reference to FIGS. 14 and 15. (2) A holding circuit 226 is set based on the output of the winning ball detection circuit 224, and the set output is given to the timing adjustment circuit 21. Timing adjustment circuit 228
is composed of, for example, a flip 70 tube, and based on a set signal from the holding circuit 226, the frequency divider 212
This circuit provides a signal to the frequency divider 212 in order to adjust the timing at which the outputs P1 and P4 are derived. At the same time, the output of the timing adjustment circuit 228 is output to the OR gate 2.
30 to a solenoid control circuit 232, the output of which is supplied to a driver 234 to control the solenoid 10.
4 is driven.

When the holding circuit 226 is initially set, as shown in FIG. 15, the timing adjustment circuit 228. or gate 230
．． A signal applied to the driver 234 via the solenoid control circuit 232 causes the drive solenoid 104 of the swing l\rad 8 to be turned on continuously.

The set output of the holding circuit 226 is also output to the delay circuit 236.
The signal is delayed by a predetermined time and is applied to one input terminal of the two-person circuits 1 to 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 i delay circuit 236. In response to the output of the timing adjustment circuit 228 being stopped and inverted to low level, the outputs P1 and P4 of the frequency divider 212 whose timing has been adjusted start being derived. Therefore, AND gate 210 connects the output of delay circuit 236 with
An AND 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,
Solenoid 82 opens and starts opening, for example, in a 0.74 second cycle. The state in which the variable ball penetrating device 16 is repeatedly opened and closed is the first state in which the variable ball penetrating device 16 is advantageous to the player.
It is in a state of

On the other hand, the output P4 of the frequency divider 212, which is timed with the output P1, is output from the AND gate 238.
A logical AND is performed at , and the result is provided 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 swinging head 98 starts to be turned off and on repeatedly, for example, at intervals of 0.71 seconds.

By the way, as shown in FIG. 15, in this embodiment, there is a gap between the opening/closing timing of the opening/closing wings 68a, 68b of the variable winning ball device 16 and the swinging timing of the swinging head 98 (see FIG. 5). , there is a certain relationship. In other words,
As shown in FIG. 15, the timing at the start of driving is adjusted, and the opening/closing blades 68a, 68b are opened (the solenoid 8
2 (on) start timing and the timing at which the swinging head 98 swings upward (turning off the solenoid 104) are matched, and both are 0.74 seconds and 0.71 seconds, respectively.
It is set to turn on/off and off/on every second. The on-timings of both of them are made to coincide, for example, at the 12th time of being on.

The reason for this is as follows. As mentioned above, when the opening/closing I:Q pieces 68a and 68b are open and the swinging head 98 is swinging downward, the pachinko balls are likely to be locked by both of them. As a result, the probability of winning a pachinko ball to the V-pocket winning opening 66 increases. On the other hand, if the above-mentioned state occurs immediately after the opening/closing wings 68a, 68b start opening/closing, and a pachinko ball easily enters the pocket prize opening 66, then the opening/closing wings 68a, 68b The opening/closing operation or the number of opening/closing times will be updated. In other words, when the opening/closing wings 68a, 68b of the variable winning ball device 16 start repeating the opening/closing process, immediately after the repetition starts, a pachinko ball easily enters the V winning hole 66, and the opening/closing wings 68a, 68b open/close. This may result in not being able to win enough prizes during repetition.

Therefore, in this embodiment, the timing at which the opening/closing wings 68a, 68b open and the timing at which the swinging head 98 swings downward are exactly coincident when the opening/closing wings 68a, 68b open, for example, for the 12th time. are associated with it. Thereby, the opening/closing wing pieces 68a, 6
During the opening/closing period of 8b, at first it is difficult for pachinko balls to enter the ■pocket prize opening, but after the middle of the period, pachinko balls are made easier to enter the V pocket prize opening 66, and the ball output rate is improved. In addition, it is said to be a pachinko game machine that has a high appeal to gamers.
