Description

[Detailed explanation of the idea] The present invention relates to improvement of pachinko machines.

In a pachinko machine, a swinging arm that operates when receiving a winning ball has one end facing the winning ball path as a ball holder, and the other end supported by a support member so as to be able to swing only in the vertical direction, Due to the weight of the winning ball resting on the ball receiver, one end of the swinging arm was lowered using the support member as a fulcrum, opening the winning ball ejection case linked to the other end of the swinging arm.

By the way, as mentioned above, since the swing arm is designed to swing only in the vertical direction by the support member at the other end, while the ball receiver is receiving the winning ball, the swing arm is A component force other than the direction acts on the ball receiver, and the moment acts on the support member, making the support relationship between the swing arm and the support member abnormal. As a result, one end of the swing arm is attached to the side wall of the winning ball guide path. There was a risk that the swing arm would not operate reliably even if it received a prize ball, and the prize ball would not be ejected smoothly.

The present invention solves the above-mentioned problems by supporting the swinging arm so as to be able to freely rotate vertically and horizontally using a supporting means, and by locating the intersection of each rotational axis on the swinging arm. By supporting the swinging arm so that it can swing in three-dimensional directions and guiding the swinging arm so that it can swing in the vertical direction by the guide means, even if the swinging arm continues to receive component forces other than the downward direction from the input ball, the swinging arm This is intended to maintain the supporting relationship between the swing arm and the support means, thereby ensuring reliable operation of the swing arm.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

A pin 32 is provided to protrude, and the other end of the swing arm 22 is supported by the pin 32 so as to be freely rotatable in the vertical direction. As shown in FIGS. 2 and 4, the axis of the pin 32 is orthogonal to the axes of the protrusions 30, 30, and the intersection of each axis is located on the swing arm 22. Therefore, the swing arm 22 can rotate symmetrically about the intersection of the rotation axes as a fulcrum.

Therefore, when attaching the swinging arm 22 to the pivot member 23, guide means are placed along both sides of the plane formed when the swinging arm 22 rotates in the vertical direction, thereby separating the ball receiver 24 and the partition. Part 12a,
12b can be evenly hit. In addition, when attaching the swinging arm 22 to the pivot member 23, the positioning work of the pivot member 23 and the swing arm 22 can be done simply by arranging the attachment part of the swing arm 22 at the intersection of the two axes. Complete. At this time, the ball receiver 24 and the side wall of the passage 9 are provided so as not to come into contact with each other. One end of an iron connecting rod 33 is connected to the other end of the swinging arm 22.
Due to its own weight, the ball receiver 24 of the swing arm 22 is urged upward using the pin 32 of the pivot member 23 as a fulcrum. The other end of the connecting rod 33 is the prize ball ejection case 3
The prize ball ejecting case 34 is connected to a prize ball ejecting case mechanism 35 that opens and closes the prize balls, and when the connecting rod 33 rises, the prize ball ejecting case 34 opens and discharges the prize balls.

and a rotating piece 36b that receives the winning ball carried by the ball receiver 24 through the passage exit 9c. As a result, the swing arm 22 is restored at regular intervals.

Next, the effect will be explained.

First, when a pachinko ball enters the winning hole on the game board surface, the pachinko ball is guided to the collecting gutter 2 as a winning ball. The winning balls are guided from the collection gutter 2 to the passage 4, and the winning balls guided to the passage 4 are carried to the ball receiving part 5a of the ball cutting member 5. The winning ball received by the ball receiving part 5a is guided to the arm part 5b, and the arm part 5b tilts downward about the pivot 6 due to the weight of the winning ball. Accordingly, the winning ball is guided by the arm portion 5b and led to the passage 9. During this time, the closing portion 5d of the ball cutting member 5 closes the passage outlet 4b to stop the next winning ball. According to this downward tilting of the arm portion 5b, the protruding shaft 5c protrudingly provided on the arm portion 5b moves toward the contact surface 15 of the movable hook piece 15.
a, and rotates the movable hook 15 clockwise in the figure using the pivot 14 as a fulcrum. And the protruding shaft 5
c engages with the engaging portion 15b of the movable hook piece 15. At this time, since a clockwise force is acting on the swinging piece 18 due to its own weight using the pivot 14 as a fulcrum, the contact piece 18a of the swinging piece 18 and the movable hook piece 15 are acting on the swinging piece 18.
remains in contact with the contact piece 15c,
Moreover, the outer surface 19a of the curved plate 19 is connected to the partition member 12.
located away from.

The winning ball that has entered the passage 9 comes into contact with the tongue piece 21a, and uses the hook piece 21 as a fulcrum around the pivot 20 as shown in FIG.
Rotate clockwise. Therefore, the swing arm 2
The second protruding shaft 22a is removed from the engaging portion 21b. The winning ball immediately rests on the ball receiver 24 of the swinging arm 22, and one end of the swinging arm 22 descends using the pin 32 of the pivot member 23 as a fulcrum due to the weight of the winning ball. In this case, the pivot member 23 is itself rotatably supported by the base plate 3a by a pair of upright plates 31, 31 and a pair of protrusions 30, 30, and also supports the other end of the swing arm 22. It is supported rotatably in the vertical direction by a pin 32, and the arm portion 28 of the swing arm 22 is connected to the partition portions 12a and 12b.
Because it is guided so that it can swing vertically with some play in the horizontal direction, the swing arm 2
2 is capable of swinging in the vertical direction, and even if a horizontal force corresponding to the play is applied to the pivot member 23 via the swing arm 22, the protrusion 30 of the pivot member 23
This means that it can be released by rotating. In this case, the partitions 12a and 12 serve as guide means.
b, but the guide means is the pivot member 2.
It is preferable that the partition portion 12 is located as far away as possible from the side surface of the swing arm 22.
It is desirable that the facing surfaces of a and 12b be as thin as possible.

One end side of the swing arm 22 is lowered, but at this time, the inner surface 19b of the curved plate 19 is located in the lowering area of the protruding shaft 22a of the swing arm 22,
The protruding shaft 22a descends while slidingly contacting the inner surface 19b. The force during this sliding contact is released by rotating the swinging piece 18 about the pivot 14 as a fulcrum. Further, the swing arm 22 is connected to the ball receiver 2 as described above.
Since the contact with the partition parts 12a and 12b of 4 is made equal, even if a horizontal force acts on the swinging arm 22 that is rotating in the vertical direction, the contact will not be biased, and the swinging will not occur. The ball receiver 24 of the arm 22 and the side wall of the passage 9 never come into contact with each other.
As one end of the swinging arm 22 descends, the other end of the swinging arm 22 rises, and the connecting rod 33 connected to the other end rises. Accordingly, the prize ball ejection case mechanism 35 connected to the other end of the connecting rod 33 is interlocked, the prize ball ejection case 34 is opened, and a prize ball is played.

The ball receiver 24 of the swinging arm 22 is located at the lower end of the passage 9b.
When reaching this point, the protruding shaft 22a of the swinging arm 22 is engaged with the engaging portion 36a of the hook 36, and at the same time, the winning ball is sent out from the ball receiver 24 to the passage exit 9c. The sent-out winning ball is placed on the rotating piece 36b on the way to the passage exit 9c, and the winning ball is placed on the rotating piece 36b.
6b pivots the hook 36 by receiving the weight of the winning ball.
The protruding shaft 22a is removed from the engaging portion 36a by rotating clockwise in FIG. 1 using the fulcrum. As a result, the swing arm 22 rises using the pin 32 of the pivot member 23 as a fulcrum. Protruding shaft 22 of swing arm 22
a reaches the swinging piece 18, but at this time the swinging piece 18
Since the outer surface 19a of the curved plate 19 formed on the peripheral edge of the curved plate 19 is located in the rising region of the protruding shaft 22a, the protruding shaft 2
2a rises while slidingly contacting the outer surface 19a. The force during sliding contact at this time rotates the movable hook piece 15 clockwise in FIG. 1 via the contact pieces 15c and 18a, using the pivot shaft 14 as a fulcrum. Therefore, from the engaging portion 15b of the movable hook 15 to the protruding shaft 5c of the ball cutting member 5,
is released, and the ball cutting member 5 receives the moment of the weight 7 about the pivot shaft 6 as a fulcrum, rotates counterclockwise in FIG. 1, and returns to the position shown in FIG. When the ball cutting member 5 returns to its original position, the closed outlet 4b is opened and is again in a condition to receive winning balls. As one end of the swinging arm 22 rises, the other end of the swinging arm 22 descends, and the connecting rod 33 descends accordingly and transmits the movement to the prize ball ejection case mechanism 35. As a result, the prize ball ejection case 34 is closed. Of course, even when one end of the swing arm 22 is raised, the one end of the swing arm 22 is guided by the partitions 12a and 12b, ensuring smooth movement of the swing arm 22.

Although one embodiment has been described above, the present invention is not limited to this, and includes the following.

In the above embodiment, the partition member 12 of the passage 9 was used as a guide means, but the substrate 3
Partition parts 12a and 12b may be provided separately between a and 3b.

As the guide means, as shown in FIG. 5, protrusions may be provided on both sides of the swing arm 22, and the protrusions may be guided by sandwiching the protrusions between the substrates 3a and 3b.

The input ball is not limited to the winning ball, but may also be an out ball.

The device of the present application is not limited to the prize ball ejecting device, but may be applied to other devices depending on the input ball.

The support means may include a spherical protrusion and a recess into which the spherical protrusion is fitted, and the support means may swing in three-dimensional directions.

As is clear from the above, the present invention
The swinging arm is rotatably supported in the vertical and horizontal directions by the support means, and the intersection points of the respective rotational axes are arranged on the swinging arm to support the swinging arm so as to be swingable in three-dimensional directions. Since the swinging arm is guided by the guide means so as to be able to swing vertically, even if the ball receiver of the swinging arm continues to receive component forces other than the downward direction from the input ball due to long-term use, the swinging arm The supporting relationship between the swing arm and the support means is maintained in a normal state, and the operation of the swing arm can be maintained in a reliable manner.Therefore, the related mechanisms linked to the swing arm can also be operated reliably. Furthermore, when attaching the swinging arm to the support means, the positioning of both can be completed by simply locating the intersection of both rotational axes at the attachment site of the swinging arm. This makes positioning work easier and faster, improving work efficiency. Further, since the above-mentioned intersection of both rotational axes is located on the swing arm, it becomes easy to equalize the contact between the swing arm and the guide means on both sides.
Therefore, it is possible to ensure that one end of the swinging arm and the side wall of the winning ball guide path are prevented from coming into contact with each other, and the reliability of the swinging arm can be improved.
