Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a winning device for a pachinko machine.

(Prior art) Conventionally, the winning device of a pachinko machine is provided with a pair of opening/closing wings, called so-called tulips, corresponding to the winning opening, which can swing from side to side, and the opening/closing wings are mechanically opened and closed. There is a game machine that changes the conditions under which pachinko balls fly into the winning hole.

Recently, a winning device for a pachinko machine has been proposed that is an extension of such a winning device and uses magnetic force to change the conditions under which pachinko balls fly into the winning hole. More specifically, a movable winning probability changing body is provided on the front side of the game board, and a rotatable actuating body is provided on the back side of the game board in correspondence with the winning probability changing body, so that magnetic attraction is achieved. Alternatively, one of the two members having a repulsive relationship is provided on the winning probability changing body, and the other is provided on the operating body in plural numbers at intervals in the circumferential direction thereof, and the above-mentioned A system is being developed in which the conditions for a pachinko ball to enter a winning hole are changed by changing the displacement position of a winning probability changing body.

By the way, the operating body of the winning device as mentioned above is
It is rotated by the weight of the pachinko balls that fly into the winning hole equipped with the winning probability changer or other winning holes, but when pachinko balls fly in and out successively, they are rotated by the first pachinko ball. Before the actuating body stops, it is further rotated by the next pachinko ball, which tends to cause a situation in which the entry condition does not change due to the first pachinko ball.

(Purpose) This invention was made in view of the above points,
Its purpose is to provide appropriate rotational resistance to the operating body.

(Structure of the invention) The feature of the present invention is that a winning probability changing body that changes the conditions for pachinko balls to fly into the winning opening is freely displaceable on the front surface of the game board with the opening of the winning opening. an actuating body is rotatably provided on the back side of the game board in correspondence with the winning probability changing body, a flapper is swingably provided in the vicinity of the actuating body, and the swinging part of the flapper is configured to rotate. Of two members facing the rotating region of the operating body and attracting or repelling each other due to magnetic force, one member is provided in the winning probability changing body as a controlled member, and the other member is provided as a control member. A plurality of pieces are provided on the operating body at intervals in the circumferential direction of the operating body, and the displacement position of the winning probability changing body is configured to change according to the rotational position of the operating body.

(Example) The present invention will be explained in detail below based on the drawings.

In Figures 1 to 3, reference numeral 1 denotes a plastic casing with openings at the bottom and rear (right side in Figure 3), and a front plate 1 having a flange.
A prize opening 2 is opened in a. As shown in FIG. 3, such a casing 1 is fitted into a fitting hole 3a formed on the board surface of a game board 3 and nailed using a nail hole 4 opened in the flange. , the casing 1 is fixed to the game board 3. A support shaft 5 is protruded from the front plate 1a of the casing 1 below the winning opening 2, and a swinging body 6 as a winning probability changing body is mounted on the support shaft 5 in the left-right direction (first
It is held so as to be able to swing freely (clockwise and counterclockwise in the figure), and its left and right swings beyond a predetermined range are restricted by stopper pins 17 and 18 that protrude from the front plate 1a. The swinging body 6 has a ball receiving guide part 6a that expands upward at its upper end, and rotates as shown in FIG. In addition, the conditions for the pachinko ball to enter the winning hole 2 are changed. In other words, winning opening 2
The opening width (width in the left-right direction in Fig. 1) is set to be large enough to hold two or three pachinko balls in parallel, but when the swinging body 6 is in the neutral position as shown in Fig. 5A, This is considered to be the best winning condition in which all pachinko balls falling within the entire opening width range of the winning opening 2 can be made to fly into the winning opening 2. Also,
As shown in FIG. 5 B or C, the rocking body 6 is
When it is in the right or left swing position, only the pachinko balls falling within the right half or left half of the opening width of the winning hole 2 can be allowed to fly into the winning hole 2. ing.

In the embodiment, the above-described rocking body 6 includes a main body 6A having a substantially Y-shaped ball receiving guide portion 6a, and is fixed to the front surface of the main body 6A, and has a ball receiving guide portion 6a.
The main body 6A is provided with a balance weight 7 below the support shaft 5, and the main body 6A is provided with a balance weight 7 below the support shaft 5.
A controlled member 8, which will be described later, is provided above.

On the other hand, the back side of the game board 3, that is, the casing 1
An operating body 9 is rotatably disposed on the back side of the front plate 1a. This operating body 9 is a rotating support shaft 10
through the left and right side plates 1b, 1c of the casing 1.
It is rotatably held in between.

The actuating body 9 has a drum portion 9a serving as the center of rotation thereof, and a plurality of (five in the embodiment) projecting portions 9b each projecting from the drum portion 9a in the radial direction. The portions 9b are arranged at equal angles in the circumferential direction around the rotation center axis of the actuating body 9. A cylindrical controlled member holding part 9c is formed at the tip of each of the protruding pieces 9b, and each holding part 9c holds a control member 1, which will be described later.
2 are installed inside. Further, a claw portion 9d is formed in each holding portion 9c in the rotational direction of the actuating body 9.
This claw portion 9d restricts the pachinko ball 15 from jumping up.

The actuating body 9 has a drum portion 9a, a protrusion portion 9b, a holding portion 9c, and a claw portion 9d, each of which is integrally formed of plastic.

A flapper 20 is swingably provided near the operating body 9. That is, casing 1
A pin 21 is stretched between the left and right side plates 1b and 1c, and the upper end side of the flapper 20 is swingably held on this pin 21. The lower end side of the flapper 20, that is, the swinging portion 22 faces the rotation area of the actuating body 9, and as the actuating body 9 rotates, the projecting piece 9b of the actuating body 9 and the swinging portion 22
is in contact with. Swinging portion 22 of this flapper 20
is made of a relatively heavy metal, which provides a suitable amount of rotational resistance to the actuating body 9, so that when a rotational force is applied to the actuating body 9, its rotation is quickly stopped. It is becoming more and more like this.
A top plate 1d is provided at the upper end of the casing 1, which corresponds to the swing area of the swing section 22, and this top plate 1d allows the flapper 20 to move outside the casing 1 around the pin 21. Rotation is regulated.

Here, the control member 12 and the controlled member 8 will be explained. Both 8 and 12 are made of members that attract or repel each other by magnetic force.
More specifically, in the embodiment, each control member 12 is a permanent magnet, and the controlled member 8 is a member attracted by the permanent magnet, such as a metal material such as iron. The five control members 12 are connected to the actuating body 9.
In the left-right direction (direction of its rotational axis),
They are distributed and provided in three positions: "left", "middle", and "right". That is, in the example,
Among the five holding parts 9c, the one located directly on the back side of the controlled member 8 in FIG. 3 is designated as 9c-1, and the holding parts 9c-2, 9c-
3, 9c-4, 9c-5, as shown in FIG. 4, the control member 12 of 9c-1 is "medium",
In 9c-2, it is "left" (as seen from the front side of the game board), in 9c-3 and 9c-4, it is "right",
In 9c-5, the arrangement relationship is "left".

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

First, as shown in FIG. 3, when the holding part 9c-1 of the actuating body 9 is at the position closest to the rocking body 6, the control member 12 of the holding part 9c-1 is in the "inside" position. Therefore, the rocking body 6 having the controlled member 8 attracted by the control member 12 is placed in the neutral position shown in FIG. 5A. From this state, pachinko ball 1
5 jumps into the winning hole 2, the holding part 9c-1
The pachinko ball 15 is placed on the projecting piece 9b having
In response to this weight, the operating body 9 rotates counterclockwise in FIG. 3, while the pachinko balls 15 that rotate the operating body 9 fall downward and are collected from the guide plate 19 through a guide gutter (not shown). Ru.

Actuating body 9 rotated by the pachinko ball 15
The rotation of the flapper 20 is immediately stopped by the resistance force exerted by the swinging portion 22 of the flapper 20, but the rotation angle of the operating body 9 until this rotation is stopped is not particularly controlled. Therefore, the holding portion 9c- of the operating body 9
An unspecified holding part among 1 to 9c-5 comes to the position closest to the rocking body 9, and the operating body 9 is stopped. When the actuating body 9 stops, the control member 12 of the holding section closest to the oscillating body 6
The swinging position of the swinging body 6 is determined by the mounting position of the swinging body 6. That is, if the holding part closest to the rocking body 6 is 9c-1, the rocking body 6 will be in the state shown in FIG. 3,9c-4, the state will be as shown in FIG. 5B.

In this way, the actuating body 9 rotates as appropriate in response to the pachinko ball 15 entering and entering the winning hole 2.
The swinging body 6 is appropriately changed in its swinging position, and the conditions for the pachinko balls to enter and enter the winning hole 2 are changed.

Although the embodiments have been described above, the present invention is not limited thereto, and includes, for example, the following cases.

The control member 12 can be installed at two locations (the oscillating body 6 can take two oscillating positions) or at four locations (the oscillating body 6 can take two oscillating positions) in the left-right direction.
can take four different swing positions) or more.

When the control member 12 is a permanent magnet, the controlled member 8 may be a permanent magnet that is attracted to or repelled by the control member 12. Furthermore, when the controlled member 8 is a permanent magnet, the control member 1
2 may be a magnet attracting member made of iron or the like.

A winning pachinko ball from another winning device may be guided to the operating body 9, and the guided pachinko ball may rotate the operating body 9.

The number of control members 12 provided at intervals in the circumferential direction of the actuating body 9, in other words, the number of holding parts 9c, can be set to an appropriate number as long as it is two or more.

The relationship between the winning probability changing body and the operating body may be such that the winning probability changing body is turned upside down depending on the rotational position of the working body, as shown in Japanese Patent Application No. 55-2124, for example.

The swinging portion 22 of the flapper 20 may have any shape as long as it faces the rotation area of the operating body 9.

The rotation angle of the operating body 9 may be determined by changing the rotational resistance by changing the weight of the swinging portion 22 of the flapper 20.

The actuating body 9 may have a cylindrical shape.

As is clear from the above, the present invention
Since the operating body is provided with a suitable rotational resistance, the operating body rotated by one pachinko ball is quickly stopped. The rotation is restarted for each pachinko ball. This means that the responsiveness of the operating body, that is, the winning probability changing body becomes better, and the practical value of this type of winning device is further increased.
