In this case, the rotating body 88 is as shown in FIG. 7A.
In the normal rotating position (this is referred to as the ejection position), the ball receiver 84 closes the winning window 38 of the plate 34, and the winning balls stored in the ball receiver 84 are transferred to the ejection opening 86 and the ejector. The winning balls are guided through the outlet 77 to the winning ball processing device 21 on the back side of the game board 15, and from this state, they are rotated approximately 90 degrees counterclockwise as seen in FIG. 7A to the rotational position shown in FIG. 7B (this (referred to as the winning position)

The winning balls introduced through 9 are stored in a winning ball receiving part 84, and the winning balls stored in this state are held in a state where they can be visually recognized from the outside. Although a decorative pattern is attached to the front side of the decorative shielding plate portion 87, this shielding plate 87 may be omitted.

Further, a rotating mechanism 91 for repeatedly rotating the rotating body 88 between the winning position and the ejecting position is disposed on the plate body 74. An example of this rotating mechanism 91 is as shown in FIG. A motor M as an electric drive source is attached to a side plate 92 attached to the left side when viewed from the rear side. Note that a solenoid may be used as the electric drive source. A cam plate 94 is attached to a rotating shaft 93 extending through the side plate 92, and a connecting rod 95 is pivotally supported between the cam plate 94 and the side plate 82 of the rotating body 88. Rod 9

8 is selected so that it rotates counterclockwise from the ejection position to the winning position. Therefore, the rotating body 88 is configured to reciprocate once between the ejection position and the winning position while the cam plate 94 makes one revolution.

The cam plate 94 is provided with a notch 96 as an ejection position detection section and a notch 97 as a winning position detection section at different positions in the axial direction of the symmetrical outer circumferential surface through the central axis of the cam plate 94. These notches 9
A discharge position detection switch S1 and a winning position detection switch S2 are disposed close to and opposite to the outer peripheral surface of the cam plate 94 so as to engage with the switches S1 and S2, and these switches S1 and S2 are connected to a common contact point a. It has normally closed and normally open contacts b and c, and its actuator 98 has a notch 9
6 and 97, the common contact a becomes the normally closed contact b, and in the other state, that is, when in contact with the outer peripheral surface of the cam plate 94, the common contact a becomes the normally open contact c.
In the normal state, the actuator 9 of the switch S1 is connected as shown in FIG. 8A.
8 is engaged with the notch 96.

Next, an example of a drive circuit for driving the rotation mechanism 91 will be explained with reference to FIG.
An AC power supply A is connected between TI1 and TI2, a motor M having an AC synchronous motor configuration is connected between output terminals TO1 and TO2, and switching contacts r2 and r1 of relays R2 and R1, which will be described later, are connected in series between terminals TI1 and TO1. The terminals TI2 and TO2 are directly connected and grounded.

In addition, the input terminal TI1 is connected to the common contact a of the switch S2 via the output terminal TO3, and its normally closed contact b is connected to the unstable multivibrator B and the timer via the input terminal TI3 and rectifier diodes D4 and D5. They are respectively connected to the input sides of circuit T, and a normally open contact c is connected via input terminal TI4 between contacts r1 and r2 of relays R1 and R2, and to a common contact a of switch S1.

The normally closed contact b of the switch S1 is an empty contact, and the normally open contact c is connected to the input side of the unstable multivibrator B via an input terminal TI5 and a rectifying diode D6.

The timer circuit T is composed of a charging capacitor C, a variable resistor VR that changes the charging time constant, a discharging diode D7, and a resistor R11, and the timer circuit T is composed of a charging capacitor C, a variable resistor VR that changes the charging time constant, a discharging diode D7, and a resistor R11. The output signal ST is configured such that the following output signal ST can be obtained.

On the other hand, a relay R2 and its control switching gate G2 are connected in series between the input terminal TI1 and the ground via a rectifying diode D8.
2 is controlled to be open by the output signal ST of the timer circuit T, and a similar relay R1 and its control switching gate G1 are connected in parallel with the relay R2 and gate G2, and the normally open contact c is output. The common contact a connects to the rectifier diode D8 side via the terminal TO4, and the resistor R connects to the common contact a via the output terminal TO5.
12 and to ground via the charging capacitor C2,
The winning ball detection switches 76 whose normally closed contacts b are connected to the gates G1 through the input terminals TI6 are connected, and the common contact a is connected to the normally open contact c of the winning ball detecting switches 76, so that the capacitors are instantaneously connected. C2 is charged, and the switching gate G1 is controlled to be in an open state by discharging this charging current.

Further, the intermittent output signal SB of the unstable multivibrator B is transmitted to a plurality of light emitting diodes FD1 to FD via the output terminal TO7, for example, three light emitting diodes FD1 to FD in this embodiment.
3 and causes them to blink while the output signal SB is obtained.

Next, its operation will be explained along with its configuration.

That is, the rotating body 88 is now in the ejection position, the winning passage 89 is closed, and the winning position detection switch S2 is in its actuator 8 as shown in FIG.
6 to engage the outer peripheral surface of the cam plate 94, and the common contact a becomes the normally open contact c side, and the discharge position detection switch S1
Assume that the actuator 86 engages the notch 96 of the cam plate 94, the common contact a is switched to the normally closed contact b side, and the charging capacitors C and C2 are each in a discharged state. In this state, relay R
1 and R2 are in a non-energized state, their contacts r1 and r2 are open, and the motor M is not energized and is in a stopped state.

In this state, the batting rod 9 is operated to fire a pachinko ball, and when it enters the winning hole 35 as a specific area, the winning ball passes through the gutter 64 and is activated by the winning ball detection switch 76 as a specific area passing ball detection means. reached,
The common contact a is switched from the normally closed contact b to the normally open contact c, so that the capacitor C2 is rapidly charged. Next, when the winning ball passes through the switch 76, the common contact a returns to the normally closed contact b side, and the electric charge charged in the capacitor C2 is supplied to the switching gate G1 from the input terminal T16 via the switch 76. This opens for a predetermined discharge time constant (for example, a time longer than the time required for the motor M to rotate and the actuators 86 of the switches S1 and S2 to disengage from the notches 96 and 97 of the cam plate 94). controlled by the state. In response, relay R1 is energized, so its contact r1 closes, and current from AC power supply A flows from input terminal TI1 to winning position detection switch S2's common contact a and normally open contact c to input terminal TI4. - Since it is supplied to the motor M through the contact r1 of the relay R1, its rotating shaft 93 is
The rotating body 88 is rotated counterclockwise when viewed from the
is rotated clockwise. At the same time, relay R
The input signal SS is supplied to the unstable multivibrator B through the contact r1 of 1, from which an intermittent output signal SB is obtained, and the light emitting diodes FD1 to
FD3 is driven to blink.

Then, as the rotary shaft 93 rotates, the actuator 98 of the discharge position detection switch S1 comes out of the notch 96 of the cam plate 94, so that the contact a is switched to the normally open contact c side. Thereafter, when capacitor C2 becomes discharged, gate G1 closes, relay R1 becomes deenergized, and its contact r1 opens. However, in this state, since the ejection position detection switch S1 is switched, the input terminal TI1 - the output terminal TO3 - the common contact a and the normally open contact c of the winning position detection switch S2 - the common contact a and the normally open contact of the ejection position detection switch S1 Normally open contact c - motor M via output terminal TI5
Since power is supplied to the motor M, the motor M continues to rotate.

As shown in FIG. 8B, the rotating body 88 is approximately
When the cam plate 94 rotates 90 degrees and reaches the winning position, the actuator 98 of the winning position detection switch S2 engages in the notch 97 of the cam plate 94, and the common contact a is switched to the normally closed contact b side, and as a result, the energizing path to the motor M that has been formed up to now is cut off, so that the rotation of the motor M is stopped. In this state, since the winning path 89 is open, the pachinko balls that have passed through the paths 51 and 52 of the guide member 53 and been jumped up by the umbrella-shaped inclined plate portion 54 of the guide member 56 are sent to the winning ball receiving portion of the rotating body 88. 84 so as to be visible from the outside.

In addition, by switching the winning position detection switch S2, the timer circuit T as a drive control means is connected to the input terminal TI1, the output terminal TO3, the common contact a and the normally closed contact b of the winning position detection switch S2.
Since power is supplied through the input terminal TI3 and the rectifier diode D5, the capacitor C of the timer circuit T is gradually charged, and an output ST that reaches a high level after about 15 seconds is obtained, and in response to this, the gate G2
opens, energizes relay R2, and closes its contact r2. Therefore, AC power supply A is connected to motor M through input terminal TI1, relay contact r2, input terminal TI4, common contact a and normally open contact c of discharge position detection switch S1, input terminal TI5, and output terminal TO1. M rotates counterclockwise again, the rotating body 88 rotates clockwise as seen in FIG. 8A, and the winning passage 89 is gradually closed by the ball receiving portion 84. At this time, since the actuator 98 of the winning position detection switch S2 is removed from the notch 97, the common contact a switches to the normally open contact c side and returns to the original position. Based on this, the timer circuit T
Since the power supply to is cut off, the capacitor C is discharged and the gate G2 is closed, and the relay R2 is deenergized and its contact r2 is opened, but instead of this, the common contact a of the winning position detection switch S2 is opened. Since power is supplied to the discharge position detection switch S1 through the normally open contact c, the motor M continues to rotate.

When the rotating body 88 returns to the ejection position, FIG.
As shown in FIG. 8A, the winning balls stored in the winning ball receiving section 84 are discharged to the back side of the game board 15 through the discharge port 77, and are processed by the winning ball processing device 21 in a number corresponding to the number of winning balls. The prize balls are delivered to the ball tray 5. In addition, in this state, the actuator 98 of the discharge position detection switch S1 engages in the notch 96, so that the common contact a returns to the normally closed contact b side, and the motor M that has been formed until now The power supply path is cut off, the motor M is stopped, and the power supply to the unstable multivibrator B is cut off, and the intermittent light emission of the light emitting diodes FD1 to FD3 is turned off. While the above operation is being performed, even if a pachinko ball enters the winning hole 35 as a specific area as a winning ball and the winning ball detection switch 76 as the specific area passing ball detection means is switched, the above operation will not be performed. There is no influence, and the rotating body 88 rotates after a certain period of time determined by the time constant of the timer circuit T has elapsed. A configuration is shown that disables the .

In the above-mentioned embodiment, the variable winning ball device rotates and holds the rotating body at the winning position based on the detection signal of the specific area passing ball detection means, and after a predetermined period of time has elapsed,
The method of rotating the rotating body back to the ejection position has been explained, but a winning ball detection switch is provided to detect winning balls that have entered the rotating body, and when this winning ball detection switch has counted a predetermined number of balls, the rotating body is returned to the ejection position. The rotating body may be returned to rotation, or the rotating body may be returned to rotation after a predetermined period of time has elapsed and a predetermined number of objects have been reached, whichever comes first.

As another example, (1) After the cam plate 94 is continuously rotated once based on the detection signal of the winning ball detection switch 76 of the specific area passing ball detection means and the rotating body 88 is rotated to the winning position. There is also a method of rotating the rotating body 88 back to the ejection position. According to this method, the cam plate 9
4 only needs to be provided with the notch 96 as the ejection position detection section and the ejection position detection switch S1, and has the advantage that the structure can be simplified since the timer circuit T used in the above-mentioned embodiment is not required. .

(2) The cam plate 94 is continuously rotated for a certain period of time based on the detection signal of the winning ball detection switch 76 of the specific area passing ball detection means, and after the rotating body 88 is rotated to the winning position, the rotating body 88 is ejected. There is also a method of repeating the operation of rotating and returning to the position multiple times. According to this method, the cam plate 94 is provided with a notch 96 as a discharge position detection section and a discharge position detection switch S1, and by reciprocating the rotary body 88 for a certain period of time, the player can Since the game is played in such a way as to make the hit ball win a prize in accordance with the timing when the ball is converted into a winning position many times, an interesting pachinko game machine can be provided.
Further, by disposing a plurality of winning ball detection switches on the game board and setting the time for reciprocating the rotating body 88 for each winning hole, it is possible to provide a pachinko gaming machine with a wide variety of variations. .

(3) The rotating body 88 is rotated and held at the winning position based on the detection signal of the winning ball detection switch 76 of the specific area passing ball detecting means, and when the ball passes through the specific area provided on the game board 15, it is moved to the ejection position. Allow rotation to return. An example of the specific area of this method will be explained based on FIGS. 1 and 2.
With the rotating body 88 converted to the winning position, the player hits the ball so that the ball hits the ball receiving portion 84 of the rotating body 88 to win a prize. What should be noted about this embodiment is that the rotating body 88 remains in the winning position until the ball passes through the winning ball device 17, which is an example of a specific area provided on the surface of the game board 15. This is a point that we will continue to maintain. That is, when a batted ball enters a prize in the winning ball device 17 with the rotating body 88 converted to the winning position, the batted ball is guided to the back of the game board, and when switches S3 to S4 are actuated, the rotating body 88 moves from the winning position to the winning ball device 17. Since the ball is converted to the ejection position, the player, while the rotating body 88 is converted to the winning position, hits the ball so as not to hit the winning ball position 17, and until the ball hits the winning ball position 17,
Since any number of batted balls can enter the ball receiver 84 of the rotating body 88, the player can hit the ball while visually checking the winning balls stored in the ball receiver 84, making it possible to provide a very interesting pachinko game machine. I can do it.

In this embodiment, an example in which a winning ball device is provided as an example of a specific area has been described, but as an example of another specific area, a passing ball detection switch that detects when a batted ball passes through a specific area on the game board surface may be used. It's okay if it's hot.

Note that the above example merely describes one embodiment of the present invention, and when the motor M is a DC motor, the AC power supply A is replaced with a DC power supply, and the rectifier diodes D4, D5, D6, D8 and It is also possible to omit the smoothing capacitors C5, C6, and C8.

Also, the cam plate 94 has a notch 9 as shown in FIG.
In the case of having protrusions 101 and 102 instead of 6 and 97, the connection relationship between the normally closed contact b and the normally open contact c of the discharge position detection switch S1 and the winning position detection switch S2 may be reversed.

Furthermore, the drive circuit is not limited to the above example, and when the cam plate 94 shown in FIG. The normally open contact c is connected to the AC power supply A, the normally open contact c is connected to ground via the relay R1 and the gate G1, the normally closed contact b is connected to the timer circuit T, and the winning position detection switch S2
The common contact a is connected to the diode D10, the normally open contact c is connected to the ground via the relay R2 and the gate G2, and the gate G1 is connected to the winning ball detection switch 7.
6, the gate G2 is controlled by the output of the timer circuit T, and the gate G2 is controlled by the output of the timer circuit T.
Even if self-holding contacts rh1 and rh2 of relays R1 and R2 are inserted in parallel with relays R1 and G2, the same operation as in the case of FIG. 9 can be obtained.

Further, the position detection switches S1 and S2 are not limited to the cam plate 94, but a cam plate may be provided on the rotary body 88 and may be placed close to the cam plate.

Furthermore, in this embodiment, the winning ball detection switch 76 is used as a specific area passing ball detecting means, and the winning ball detecting switch 76 is used as a specific area passing through the winning hole 3.
5 position, and the winning ball device is operated based on the winning signal from the winning ball detection switch 76, but this is not limited to the above case. It is also possible to use a signal generated when the number of out balls reaches a predetermined number or more.

〔Effect of the invention〕

In the present invention, even if the ball passes through a specific area during the first state period, it is invalidated, so even if there is a slight deviation in the adjustment of obstacle nails etc. provided on the game board, it is assumed that the ball passes through a specific area. The actual operating income and expenses will not be significantly different. In addition, as a result of this, it is possible to adjust the nails to make it easier to pass through a specific area to some extent, thereby increasing the player's interest and thus providing a pinball game machine that is popular with players. It is something that can be done.
