Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a prize ball ejecting device for a pachinko machine, and in particular, the present invention relates to a prize ball ejecting device for a pachinko machine. It is possible to check whether there is a predetermined number of pachinko balls in the ejection case, and when a predetermined number of pachinko balls are stored, the prize balls can be ejected, and when the predetermined number of pachinko balls are not stored, the prize balls can be ejected. This is to ensure that the prize balls are ejected in a fixed quantity.

The features of the present invention include a swinging arm that operates upon receiving a prize ball and opens and closes the exit of the prize ball ejection case; An opening/closing rotating claw to which rotational force in the opening direction is applied when receiving the weight of a pachinko ball to be introduced into the ejection case, and a rotating force in the closing direction to the opening/closing rotating claw. The weight is balanced and linked to the opening/closing rotating claw, and when the weight of the pachinko balls is not applied to the opening/closing rotating claw, the swinging arm acts on the swinging arm to move the prize ball discharging case. When the locking swing claw member for restricting displacement in the direction of opening the outlet and the locking swing claw member are not performing a locking action on the swing arm, When the swing arm receives a winning ball and is displaced, the swing arm forcibly rotates the opening/closing rotating claw in the direction of closing in accordance with the displacement.

An embodiment of the present invention will be described below.

In the drawings of this embodiment, in order to facilitate understanding of the present invention, the front side of the substrate 2 is drawn with a solid line, and the side opposite the substrate 2 is drawn with thin lines.

In FIG. 1, reference numeral 1 denotes a prize ball ejection case that is supported by a pivot shaft 1a from the opposite side (back side of the page) through a transparent substrate 2, and the outlet 1b of the prize ball ejection case 1 at the lower end faces the ball ejecting gutter 13. , the outlet 1b has
The claw portion 3b of the movable receiving piece 3, which is pivotally supported by a pivot 3a, is inserted from the opposite side with the substrate 2 in between. In addition, the movable receiving piece 3 is a copper piece 3c.
The clockwise swing is regulated by. A protrusion 1c is provided at the lower end of the prize ball ejection case 1 so as to protrude from a notch 2a formed in the base plate 2 toward the front side of the base plate 2, and the protrusion 1c is provided in an engagement relationship with the engaging member 4. This restricts the prize ball ejection case 1 from swinging counterclockwise about the pivot 1a.

The engaging member 4 is integrally formed at one end of the connecting rod 5 and is pivotally supported by a pivot 4a, and one end of another connecting rod 6 is pivotally supported at the other end of the connecting rod 5. An iron connecting rod 8 is pivotally supported at the center of the ball so that it also functions as a heavy peg that rises as the swinging arm 7 moves down in response to winning balls.

When the swing arm 7 is in the position shown in FIG. 1, the engaging member 4 is in a position where it can engage with the protrusion 1c of the prize ball ejection case 1, and the prize ball ejection case 1 is aligned with the pivot shaft 1a. oscillates counterclockwise from the starting point,
The outlet 1b of the prize ball discharge case 1 is prevented from facing the prize ball gutter 9, and when the swinging arm 7 is lowered to receive the winning ball, the engaging member 4 can engage with the protrusion 1c. This allows the prize ball ejection case 1 to swing counterclockwise about the axis 1a as a starting point.

The connecting rod 6 includes a cam consisting of a curved portion 6a and a raised portion 6b, and a stepped portion 6c, and the connecting rod 6 is configured such that its displacement is controlled by a locking swing claw member 18, which will be described later. It's summery.

The swinging arm 7 has one end biased upward from the pivot support member 7a by the weight of the connecting rod 8, and receives winning balls from a collecting gutter 10 connected to a winning device (not shown). When this occurs, the swing arm 7 descends. At this time, the control means 11 reliably receives the winning ball and the swinging arm 7
Controls the vertical movement and reciprocation of the

One end of another connecting rod 12 is pivotally supported at the other end of the connecting rod 6, and an engaging rod 12a is inserted through the notch 2b formed in the base plate 2 at the other end of the connecting rod 12. It is placed perpendicular to the plane of this paper.

In addition, this connecting rod 12 is connected to the pivot 12b on the front side of the board 2.
It is supported by

The engagement rod 12a and the engagement member 14e of the stopper 14, which is pivotally supported from the opposite side via the base plate 2 by a pivot 14a, constitute a locking mechanism L for opening and closing the prize ball ejection case 1. That is, when the flow of pachinko balls from the prize ball tank (not shown) has stopped, the one end 14b side of the stopper 14 is aligned with the pivot 14a.
Since the stopper 14b is urged upward by the heavy stud 14c as a starting point, one end 14b of the stopper is pressed against the upper wall of the passage 15 as shown in FIG. 1, and the other end 14d of the stopper is engaged The portion 14e is located so that it can be engaged when the engagement rod 12a is lowered from the pivot 12b. Therefore, even if a winning ball is carried to the swinging arm 7, the swinging arm 7 will not be lowered by the lock mechanism L.

On the other hand, when the flow of Pachinko balls is continuous, the Pachinko balls resist the biasing force of the heavy stud 14c and lower the one end 14b side of the stopper to communicate with the passage 15, so that they are not engaged with the engaging rod 12a. It does not engage with the mating portion 14e. Thus, this locking mechanism is activated when there is a risk that the prize balls will not be supplied in quantity.

Exit 15 of passage 15 is located above prize ball ejection case 1.
a faces the entrance 1e of the prize ball ejection case 1, and between the exit 15a of the passage 15 and the entrance 1e of the prize ball ejection case 1, there is a shaft 16a pivoted from the opposite side via the base plate 2. The gourd part 16b of the rotatable opening/closing rotating claw 16 is inserted to open and close the entrance 1e of the prize ball ejection case 1, and the pachinko to be introduced into the prize ball ejection case 1 is inserted. When receiving the weight of the ball, the claw portion 16b is given a rotational force in the opening direction.

The opening/closing rotating claw 16 is connected to connecting members 17a and 17b.
It is connected to one end 18a of the locking swing claw member 18 via. Here, the pin 17c passes through a notch 2c formed in the base plate 2 and pivotally supports the opening/closing rotating claw 16 and the connecting member 17a.

The locking swinging claw member 18 has a T-shape, and applies a rotational force to the opening/closing rotating claw 16 in the direction of closing the prize ball case entrance 1e by means of a pivot 18b on the near side of the board 2. The one end 18a is different from the one end 18a.
A roller 18d is rotatably attached to the roller 8c.
The roller 18d is adapted to come into contact with the cam of the connecting rod 6. To explain in more detail, when the locking swinging claw member 18 is in the position shown in FIG. The claw portion 18e of the claw member 18 is connected to the stepped portion 6 of the connecting rod 6.
c, and prevents the connecting rod 6 from rising and prevents the swinging arm 7 from descending even if it receives a winning ball. At this time, the roller 18d is in contact with the curved part 6a, and when the gourd part 16b of the opening/closing rotating claw 16 receives the load of the pachinko ball, regardless of whether it is continuous or discontinuous, the opening/closing rotating claw 16 rotates,
The rotation is transmitted to the locking swing claw member 18 via the connecting members 17a and 17b, and the melon part 18e is connected to the stepped part 6c.
It's starting to deviate from that. As shown in Fig. 2, the pachinko balls are connected in succession through the passage 15,
When a load is applied to the claw portion 16b of the rotating opening/closing claw 16, the locking swinging claw member 18 swings about the pivot 18b, and the claw portion 18e is separated from the stepped portion 6c. When the swing arm 7 receives a winning ball, the swing arm 7 can be lowered. In this state, when the swinging arm 7 descends after receiving the winning ball,
The roller 18d of the locking swinging claw member 18 moves from the curved portion 6a to the riding-up portion 6b, which causes the locking swinging claw member 18 to swing clockwise from the pivot point 18b. The swinging motion is caused by the connecting member 17
The information is transmitted to the opening/closing rotating pawl 16 via a and 17b. Therefore, the rotating claw 16 for opening and closing
The melon part 16b is given a forced rotational force,
It becomes impossible to rotate, and pachinko balls are prevented from flowing out from the exit 15a of the passage 15 (see FIG. 3). Of course, at this time, the engaging member 4 is disengaged from the protrusion 1c of the prize ball ejection case 1, and the pachinko balls in the prize ball ejection case 1 are ejected as prize balls.

Next, the operation of the above configuration will be explained.

In the state shown in FIG. 1, there are no pachinko balls in the pachinko machine, and the claw portion 16b of the rotating opening/closing claw 16 is not receiving any load from the pachinko balls. Therefore, the gourd part 18e of the locking swinging claw member 18 is engaged with the stepped part 6c, and accordingly, the connecting rod 6 is prevented from rising, and the swinging arm 7 is in a state in which it does not operate even if it receives a winning ball. It is becoming.

In addition, pachinko balls are flowed into the passage 15 from a prize ball tank (not shown). At this time, the claw portion 16b of the opening/closing rotating claw 16 is rotatable and rotates under the load of the pachinko balls coming from the exit 15a of the passage 15, and successively releases the pachinko balls into the prize ball ejection case 1. Put it inside. When the pachinko balls are continuously connected from the prize ball tank (not shown) to the inside of the prize ball discharge case 1, the claw portion 16b of the rotating opening/closing claw 16 receives the load of the pachinko balls in a stationary state and moves from the stepped portion 6c. It is maintained in a dislocated state (see Figure 2).

After that, when the swinging arm 7 descends in response to the winning ball, the connecting rod 6 rises, and the roller 18d moves to the curved portion 6a.
The locking swinging claw member 1 moves from
8 swings clockwise with the pivot 18b as the starting point. The swinging motion is caused by the connecting members 17a and 17b.
The force is transmitted to the opening/closing rotating claw 16 through the opening/closing rotating claw 16, and the claw portion 16b of the opening/closing rotating claw 16 is given a forced rotational force, making it unable to rotate. Therefore, no pachinko balls are supplied into the prize ball ejection case 1, and at the same time, the engagement between the engaging member 4 and the protrusion of the prize ball ejection case 1 is released, so that the prize balls are not supplied. The pachinko balls in the discharge case 1 are discharged as prize balls.

In addition, in the case where the stopper 14 is stuck due to dirt or the like and the passage 15 is in communication, and the locking mechanism L between the engaging rod 12a and the engaging portion 14e does not work, the prize ball tank (not shown) can also be removed from the prize ball tank (not shown). When pachinko balls are connected in succession, it functions as described above without any problems. However, if pachinko balls do not flow into the passage 15 for some reason, the claw portion 16b of the opening/closing rotating claw 16 will not receive any load, as in the case of no pachinko balls in FIG. Claw portion 18 of locking swing claw member 18
e contacts the step portion 6c. Therefore, the moving rod 6 is prevented from rising, and even if a winning ball is received, the swinging arm 7 will not descend. This state can be easily detected by providing a detection means such as a limit switch to detect this state.

As is clear from the above description, the present invention does not eject prize balls unless a predetermined number of pachinko balls are supplied into the prize ball ejection case, so it is possible to reliably discharge a fixed amount of prize balls. This will not cause any unexpected damage to the player.

In addition, the prize ball discharging case 1 is weight-balanced and pivoted so that it is biased in the opening direction when filling with pachinko balls, so it takes less time to reach the open position, and the case 1 is not allowed to hang down. Because of this, the speed at which the pachinko balls are ejected is fast, or in other words, the time from when the pachinko balls are won to when they are ejected is short, which doubles the interest of the game.

In addition, since the prize ball ejection case 1 is suspended as described above, the filling speed of the pachinko balls after returning to the original position after ejecting the pachinko balls is fast. However, when the next pachinko ball ejecting operation is performed, ejection case 1 is already in place.
The filling of pachinko balls has been completed, and therefore, when winning a prize, the ejection case 1 is not ejected when it is empty, and the number of balls less than a predetermined number is not ejected.
