<Prior Art> As is well known, a pachinko machine is provided with various sorters in order to improve game playability. For example, a pachinko machine having a dual rotating body arranged coaxially is disclosed in Japanese Patent Publication No. −15311
The official gazette and the Japanese Utility Model Publication No. 48-3386 are known. That is,
The former is a rotary plate which is connected to a rotary drive source and which has a winning groove, a guide member which is arranged so as to surround the rotary plate and has a winning ball entrance, and a winning ball receiving portion which is provided outside the guide member. And a rotating member that rotates relative to the rotation of the rotating plate, and the sphere received by the winning ball receiving portion can be guided to the winning hole formed on the substrate by the winning groove of the rotating plate. It was formed. Also, the latter is
A surrounding frame is erected on the front surface of the mounting substrate, and within the surrounding frame, a rotatable large rotating body and a small rotating body are coaxially and rotatably attached to a space formed in the central portion of the rotating body. A ball passage communicating with the empty portion is formed in the large rotating body, and a ball pocket is formed in a portion avoiding the passage, and the ball pocket provided in the small rotating body faces the passage of the large rotating body, and the passage is surrounded by a surrounding frame. Each of them is urged by a weight so as to face the opening.

<Problems to be Solved by the Invention> However, the conventional sorting device lacks playability because it guides a ball in a winning groove or passage provided in a rotating body or a ball pocket to a predetermined winning hole. Moreover, since the guide member and the surrounding frame are present, the winning area of the ball is small, and the change or the chance is small.

<Means for Solving the Problem> The present invention has been proposed in view of the above, and a first rotating body having a substantially cylindrical shape and a frame body provided with a notch through which a sphere can pass is provided on a substrate. The second rotary body is rotatably supported, the second rotary body is rotatably coaxially mounted on the first rotary body, and the second rotary body is provided with a ball receiving portion opening toward the outer peripheral surface. The first rotating body and the second rotating body are rotated in different modes by the drive of the drive source, and the sphere that has flowed in through the notch is received by the ball receiving portion, and the sphere is received by the first rotating body and the first rotating body. Due to the positional relationship with the two rotating bodies, the spheres are rotatably transferred while being held in the ball receiving portion, and the held balls can be discharged when the opening end of the ball receiving portion faces the notch. is there.

Furthermore, due to the positional relationship between the first rotating body and the second rotating body, when ejecting a sphere, the location where the opening end of the sphere receiving portion and the cutout portion are aligned faces downward. It is a feature.

<Operation> The first rotating body and the second rotating body which are coaxially rotated by the drive of the drive source.
By changing the relative position of the rotating body, the ball can be fitted into the ball receiving portion provided on the second rotating body, the ball can be held in the ball receiving portion, or the held ball can be discharged. Since the movement of the robot can be changed without any artificial factor intervention, and the position of the notch provided in the first rotating body moves rotationally, the sphere can flow into the first rotating body from various directions. Becomes

<Embodiment> Hereinafter, the present invention will be described with reference to the illustrated embodiment. A distribution device 1 according to the present invention is generally a first rotating body in which a ball inflow / outflow possible region 2 and a ball inflow / outflow blocking region 3 are formed. 4 and a second rotating body 6 having a plurality of ball receiving portions 5 opening toward the outer peripheral surface are coaxially and rotatably mounted on both shafts, and both rotating bodies 4 and 6 are driven by driving a drive source. It was done like this.

In the first rotating body 4, for example, four standing pieces 8 are provided at equal intervals on the peripheral portion of the disk-shaped rotating substrate 7, and the portions where the standing pieces 8 are present serve as the ball inflow / outflow prevention area 3, and each standing piece 8 stands up. A space between the pieces 8 is used as a sphere inflow / outflow area 2, and a shaft hole 9 is formed in the rotating substrate 7. In the illustrated embodiment,
A cylindrical cylinder shaft portion 10 is provided on the back side of the rotary substrate 7 so that a shaft hole 9 is formed in the cylinder shaft portion 10.

The second rotating body 6 has a rotating disc 11 which can be loosely fitted inside the upright piece 8 of the first rotating body 4, and a shaft hole 9 of the first rotating body 4 at the center of the rear side of the rotating disc 11. Rotating shaft that can be inserted freely
12 is extended. The turntable 11 is provided with a plurality of ball receiving portions 5 ... Opening toward the outer peripheral surface. For example, in the embodiment shown in FIG. 3, five ball receiving portions 5 are provided in a notch shape,
In other words, the five arms 13 extend almost radially from the center.

Then, the rotary shaft 12 of the second rotary body 6 as described above is inserted into the shaft hole 9 of the first rotary body 4, and one output shaft of the motor 15 having two output shafts 14a and 14b as drive sources. Connect to 14a. In addition, the cylindrical shaft portion 10 of the first rotating body 4 is replaced with the bearing portion of the substrate 16.
17 and the rear surface of the cylinder shaft 10 is driven gear 18
Fasten. The driven gear 18 meshes with a driving gear 19 fixed to another output shaft 14b of the motor 15 to form a gear mechanism. In this embodiment, the output of the motor 15, which is the drive source, is the same in the same direction and at the same speed, and the first rotating body 4 and the second rotating body 6 have the same number of teeth of both gears of the gear mechanism. Although it is set to rotate in the opposite directions at the same speed, it is also possible to set the rotation axis directions of both rotating bodies 4 and 6 to be the same, or the rotating speeds of both rotating bodies 4 and 6 are You may set up differently. Further, instead of the motor 15 having the two output shafts 14a and 14b, the output obtained from one output shaft is distributed by the gear train, and the first rotating body 4 and the second rotation are set to be rotationally driven. Good.

In the distribution device 1 configured as described above, when the motor 15 is driven, the first rotating body 4 rotates counterclockwise and the second rotating body 6 rotates clockwise in FIG. When the ball receiving portion 5 of the second rotating body 6 faces the ball inflow / outflow area 2 of the first rotating body 4, the flowing down ball can flow into the ball receiving portion 5, and the ball receiving portion 5 moves. When it is out of the inflow / outflow possible area 2, the inflow of the sphere becomes impossible. not to mention,
The sphere can flow in most easily when both the sphere inflow / outflow area 2 and the sphere receiving portion 5 face upward, but in the present invention, since there are no obstacles around the two rotating bodies 4 and 6, A ball that bounces and jumps in from the side can also flow into the ball receiving portion 5, creating a chance to win a prize over a wide area.

Then, the second rotating body 6 holding the ball continues to rotate,
The opening surface of the ball receiving portion 5 reaches below the horizontal line, and
The opening surface of the ball receiving portion 5 faces the ball inflow / outflow area 2, and an end edge on the rear surface side with respect to the rotation direction of the arm portion 13 forming the ball receiving portion 5 of the second rotating body 6 (hereinafter, simply referred to as a rear end).

When the distance is smaller than the diameter of the sphere, the ball continues to rotate while holding the sphere, and the rear edge 1 of the arm 13 is released.
The sphere is ejected when the distance between 3'and the rear edge 8b of the standing piece 8 becomes wider than the diameter of the sphere.

Therefore, it is not known where the falling ball can flow in and where it is discharged, which improves the game. Moreover, the number of sphere inflow / outflow possible regions 2, in other words, the number of sphere outflow / inflow prevention regions 3 and the number of ball receiving portions 5 are made different, and in the illustrated embodiment.
Since it is 4: 5, even if both rotators 4 and 6 rotate at the same speed, the relative position of both rotators 4 and 6 will shift by 4/5 for each rotation,
It is difficult to predict which ball receiving portion 5 the ball will be released on when the prize is received, and it is difficult to aim.
Therefore, the game can be enjoyed without being influenced by the skill of the game.
