Flashes while you are on.

Next, the operation will be described together with the configurations of the pachinko gaming machine and the variable winning ball device 30. Now the rotating body 88
Is in the discharge position and the prize passage 89 is closed,
Further, as shown in FIG. 13, the winning position detection switch S2
Is engaged with the outer surface of the cam plate 94 by the operator 86, the common contact a is on the normally open contact c side, and the discharge position detection switch S1 is provided with the notch 96 of the cam plate 94 via the operator 86. , The common contact a is switched to the normally closed contact b side, and the charging capacitors C and C2 are in a discharging state, respectively. In this state, the relays R1 and R2 are
Are in the energized state, their contacts r1 and r2 are opened, the motor M is not energized, and is in a stopped state.

In this state, the striking rod 9 is operated to shoot a pachinko ball, and when this enters the winning hole 35 as the specific area, the winning ball passes through the gutter 64 and the winning ball as the specific area passing ball detecting means. It reaches the detection switch 76 and its common contact a
Switches from the normally-closed contact b to the normally-open contact c side, so that the capacitor C2 is rapidly charged. Next, when the winning ball passes through the switch 76, the common contact a thereof returns to the normally closed contact b side, and the electric charge charged in the capacitor C2 is transferred from the input terminal T16 through the switch 76 to the switching gate G.
1, which is equal to or longer than a predetermined discharge time constant (for example, the time required for the motor M to rotate and the actuator 86 of the switches S1 and S2 to disengage from the notches 96 and 97 of the cam plate 94). Open time). In response to this, the relay R1 is energized so that it is energized and its contact r1 is closed, and the current from the AC power supply A is input to the input terminal T11.
It is supplied to the motor M through the common contact a and the normally open contact c of the winning position detection switch S2, the input terminal T14, and the contact r1 of the relay R1, so that its rotation shaft 93 rotates counterclockwise as viewed in FIG. Accordingly, the rotating body 88 is rotated clockwise. At the same time, the contact r1 of the relay R1
The input signal SS is supplied to the non-stable multivibrator B through the output signal SB to obtain the intermittent output signal SB.
The light emitting diodes FD1 to FD3 are driven to blink.

Then, in response to the rotation of the rotary shaft 93, the operator 98 of the discharge position detection switch S1 is removed from the notch 96 of the cam plate 94, so that its contact a is switched to the normally open contact c side. Thereafter, when the capacitor C2 is discharged, the gate G1 is closed, the relay R1 is deenergized, and its contact r1 is opened. However, in this state, since the discharge position detection switch S1 is switched, the input terminal T11-the output terminal T03-the winning position detection switch S2.
The power is supplied to the motor M via the common contact a and the normally-open contact c-the common contact a of the discharge position detection switch S1 and the normally-open contact c-output terminal T15, so that the motor M continues to rotate. .

Therefore, as shown in FIG.
Is rotated about 90 degrees and reaches the winning position, the cam plate 94
Has rotated about 180 degrees, the operator 98 of the winning position detection switch S2 engages in the notch 97 of the cam plate 94, and its common contact a switches to the normally closed contact b side. Since the energization path to the motor M formed so far is cut off, the rotation of the motor M is stopped. Winning passage 8 in this state
Since 9 is open, the pachinko ball that is flipped up by the umbrella-shaped inclined plate portion 54 of the guide member 56 through the passages 51 and 52 of the guide member 53 is visible to the winning ball receiving portion 84 of the rotating body 88 from the outside. It is stored in the state.

Further, by switching the winning position detecting switch S2, the timer circuit T as the drive control means has an input terminal T11-output terminal T03-common contact a and normally closed contact b-of the winning position detecting switch S2. Since the power is supplied through the input terminal T13 and the rectifying diode D5, the capacitor C of the timer circuit T is gradually charged, and the output ST which becomes high level is obtained after about 15 seconds, and the gate G2 is opened accordingly. Relay R2 is energized, and its contact r2 is closed. Therefore, AC power supply A
Is an input terminal T11-relay contact r2-input terminal T14-
The motor M through the common contact a and the normally open contact c-input terminal T15-output terminal T01 of the discharge position detection switch S1
, The motor M rotates again in the counterclockwise direction, the rotating body 88 rotates in the clockwise direction as seen in FIG. 9, and the ball receiving portion 84 gradually closes the winning passage 89.
At that time, the winning position detection switch S2 is operated by the operator 9
Since 8 is disengaged from the notch 97, the common contact a is switched to the normally open contact c side and returns to the original position. Based on this, the power supply to the timer circuit T is cut off, the capacitor C is discharged, the gate G2 is closed, the relay R2 is de-energized, and its contact r2 is opened. However, instead of this, the winning position Power is supplied to the discharge position detection switch S1 through the common contact a and the normally open contact c of the detection switch S2, so that the motor M continues to rotate.

When the rotating body 88 is returned to the discharge position, as shown in FIG.
And, as shown in FIG. 9, the prize balls stored in the prize ball receiving portion 84 are discharged to the back side of the game board 15 through the discharge port 77, and the prize ball processing unit 21 generates the number of prize balls corresponding to the number of prize balls. It is led out to the upper ball saucer 5. In this state, the discharge position detection switch S1 has its operating element 98 engaged in the notch 96, so that the common contact point a returns to the normally closed contact point b side, and the motor that has been formed up to now is formed. The power supply path of M is cut off, the motor M is stopped, and the energization to the unstable multivibrator B is cut off, so that the light emitting diode FD
The intermittent light emission of 1 to FD3 is turned off. While the operation is being performed, even if a pachinko ball enters the winning hole 35 as the specific area as the winning ball and the winning ball detection switch 76 as the specific area passing ball detecting means is switched, the operation is affected. However, the rotating body 88 is configured to rotate after a lapse of a fixed time determined by the time constant of the timer circuit T. Therefore, the output of the specific area passing ball detecting means, which is a feature of the present embodiment, can be obtained. The invalid configuration is shown.

In the above-described embodiment, the variable winning ball device 30 rotates and holds the rotating body 88 at the winning position based on the detection signal of the specific area passing ball detecting means, and after a predetermined time elapses,
The method of rotating and returning the rotating body 88 to the discharge position has been described. However, a winning ball detecting switch for detecting a winning ball that has won a prize is provided on the rotating body 88, and when the winning ball detecting switch counts a predetermined number, the rotating body 88 is rotated. The rotary member 88 may be returned to the ejecting position by turning, or the turning member 88 may be returned by turning when a predetermined time has elapsed or a predetermined number has been reached, whichever comes first. Also,
Although the AC motor M is shown in the above-described embodiment, when the motor M is a DC motor, the AC power supply A is replaced with a DC power supply, and the rectifying diodes D4, D5, D are used.
6, D8 and smoothing capacitors C5, C6, C8 can be omitted.

When the cam plate 94 has protrusions 101 and 102 instead of the notches 96 and 97 as shown in FIG. 14, the normally-closed contacts b of the discharge position detection switch S1 and the winning position detection switch S2 and The connection relationship of the normally open contact c may be reversed. Then, when such a cam plate 94 is applied, a drive circuit as shown in FIG. 15 may be configured. To briefly explain this, the common contact a of the discharge position detection switch S1 is connected to the AC power source A via the rectifying diode D10, and the normally open contact c is connected to the relay R1 and the gate G1.
The normally closed contact b is connected to the timer circuit T via the ground, the common contact a of the winning position detection switch S2 is connected to the diode D10, and the normally open contact c is connected to the relay R.
2 and the gate G2 and are respectively connected to the ground, the gate G1 is controlled by the winning ball detection switch 76, the gate G2 is controlled by the output of the timer circuit T, and the relays R1 and R2 are parallel to the gates G1 and G2. Even if the self-holding contacts rh1 and rh2 of
The same operation as in the case of FIG. 13 can be obtained.

(2) Based on the detection signal of the winning ball detection switch 76 of the specific area passing ball detecting means, the rotating body 88 is rotated and held at the winning position, and when the hit ball passes through the specific area provided on the game board 15, Turn back to the eject position.

The point to be noted in the present embodiment is that the rotating body 88 remains in the winning position until the hit ball passes through the winning ball device 17 as an example of the specific area arranged on the surface of the game board 15. Is the point to continue to hold. That is, when the ball hits the winning ball device 17 in a state where the rotating body 88 is converted to the winning position, the ball is guided to the back surface of the game board and the switch S3 or S4 is operated,
Since the rotating body 88 is converted from the winning position to the discharging position,
The player hits the winning ball device 17 so as not to win the hit ball in the state where the rotating body 88 is converted into the winning position, and until the player wins the winning ball device 17, the ball receiving portion 84 of the rotating body 88. It is possible to provide a very entertaining pachinko game machine because the player can hit the ball while visually checking the winning balls stored in. In addition, as an example of the specific area, the winning ball device 17
Although the example in which is provided is shown, as another example of the specific area, a passing ball detection switch that detects that a hit ball passes through a specific area of the game board surface may be used.

In any of the above-described embodiments, the winning ball detecting switch 76 is used as the specific area passing ball detecting means, and the winning ball detecting switch 76 is provided at the position of the winning hole 35 as the specific area. Detection switch 76
