Description

  The present invention relates to a rotary lottery machine that can discharge a plurality of balls simultaneously.

  Generally, it is a lottery machine used for shopping malls, etc. It has a handle with a hexagonal column or octagonal box, and it is a rotary type that randomly picks one of many balls in it by rotating it. This lottery machine is known as an Arai-type lottery machine (Patent Document 1), and a lottery system is adopted in which a prize is determined by the color of the ball that has been taken out.

  Conventionally, in such a lottery machine, various balls can be discharged by separating them one by one using a rocking body as shown in Patent Document 2, for example, so that the balls can be reliably discharged one by one for each rotation. Have been devised.

  However, the conventional lottery machine can only eject one ball per rotation, so in a shopping mall or large supermarket with a large scale and a large number of customers, the number of lotteries is increased when one person draws many times. There was a problem that it took more time.

  In addition, only the lottery system described above can be adopted, the number of types of the color of the ball and the number of types of the prize are the same, and if the type of the color of the ball is limited, the type of the prize cannot be increased, or the number of types of the prize is increased. There was a problem that the number of types of balls had to be increased.

  In view of the above problems, the problem to be solved by the present invention is to provide a lottery machine that does not take a long time even in a venue with a large number of customers and can increase the types of prizes without increasing the types of balls. It is to be.

The invention according to claim 1 is a polygonal box-shaped box that accommodates a large number of balls in an internal space, and the ball box is rotatable about the central axis of the bottom wall that forms the bottom surface of the polygonal column. becomes a central axis and a horizontal support for supporting members, the ball box on one side wall of polygonal prism, the ball a plurality Bei give a discharge hole of the passable size only one, the discharge hole An inner wall is provided on the inner side of the side wall provided in parallel with the side wall and with a gap through which only one of the balls can pass. Are provided with the same number of guide holes as the discharge holes, and a slide plate that slides back and forth in the rotational direction as the ball box rotates is disposed in the gap, The slide plate is provided with the same number of through holes as the discharge holes so that only one of the balls can pass therethrough. The through hole of the slide plate is alternately communicated with the discharge hole and the guide hole at the front and rear stroke ends of the sliding, and in the rotational direction front of the side wall provided with the discharge hole. A guide groove that guides the ball to the guide hole with a width and depth that allows only one of the balls to pass from the side wall positioned to the guide hole is formed in the same number as the guide hole substantially parallel to the rotation direction. The ball box has an inclined portion that inclines downward from each of the two bottom walls toward the guide groove, and the opening of the guide groove is arranged in front of the guide hole in the rotation direction. The present invention relates to a lottery machine characterized in that it has a ball shield that closes most recently .

According to a second aspect of the present invention, a second guide groove that guides the ball to the guide hole with a width and depth that allows only one of the balls to pass therethrough is substantially parallel to the rotation direction inside the inner wall. The same number as the guide hole is formed,
2. The ball box according to claim 1, further comprising a second inclined portion that is inclined downward from each of two bottom walls toward the second guide groove .

According to the first aspect of the present invention, a ball box that accommodates a large number of balls in an internal space in a polygonal columnar box, and the ball box is rotatable about the central axis of the bottom wall that forms the bottom surface of the polygonal column; The ball box is composed of a support member that horizontally supports the central axis, and the ball box is provided with a plurality of discharge holes having a size that allows only one ball to pass through one side wall of the polygonal column, thereby discharging the ball. Since the same number can be discharged at the same time, the lottery time can be shortened. Further, since the prize can be determined by the combination of the colors of the balls discharged at the same time, the types of the prize can be increased without increasing the kinds of the colors of the balls.
An inner wall is provided on the inner side of the side wall provided with the discharge hole, with a gap parallel to the side wall and allowing only one ball to pass between the side wall and the inner wall. The same number of guide holes as the number of discharge holes are provided, and a slide plate that slides back and forth in the rotational direction with the rotation of the ball box is disposed in the gap. The number of through-holes that can pass only one ball is the same as the number of discharge holes, and the through-holes of the slide plate alternate between the discharge holes and the guide holes at the front and rear stroke ends. By communicating with each other, the same number of balls as the discharge holes can be discharged at the same time every rotation.
In addition, a guide groove that guides the ball to the guide hole with a width and depth that allows only one ball to pass from the side wall located in the rotation direction of the side wall provided with the discharge hole toward the guide hole rotates. The ball box is formed in the same number as the guide hole substantially parallel to the direction, and the ball box has an inclined portion inclined downward from each of the two bottom walls toward the guide groove, so that the ball is surely inserted into the guide hole. Therefore, the same number of balls as the discharge holes can be discharged at the same time for each rotation more reliably.
Furthermore, by having a ball guard that closes the opening of the guide groove immediately in front of the rotation direction of the guide hole, the place where the ball enters the guide groove can be restricted, and a large number of balls are accommodated. However, since the weight of a large number of balls is not added to some of the balls arranged in the guide groove, the balls in the guide groove are not clogged and the balls do not enter the guide hole. The same number of balls as the discharge holes can be discharged simultaneously.

According to the second aspect of the present invention, the second guide groove that guides the ball to the guide hole with a width and depth that allows only one ball to pass through the inner wall is formed in the guide hole substantially parallel to the rotation direction. The ball box has a second inclined portion that is inclined downward from each of the two bottom walls toward the second guide groove, thereby guiding the ball more reliably to the guide hole. Therefore, the same number of balls as the discharge holes can be discharged at the same time every rotation.

Hereinafter, a preferred embodiment of a lottery machine according to the present invention will be described with reference to the drawings.
FIG. 1 is an external view of a lottery machine according to the present invention.
As shown in FIG. 1, a lottery machine (100) is a regular octagonal box that contains a lot of lottery balls (S) (not shown in FIG. 1) and a ball box (101). And a support member that rotatably supports (101). The support member includes a support leg (103) that horizontally supports a rotating shaft (102) that connects the center of the bottom wall (1) that forms the bottom surface of the regular octagonal prism of the ball box (101), and a support leg (103) that stands upright. The pedestal (104) is provided.
Note that the shape of the ball box (101) may be a polygonal column, and is not limited to a regular octagonal column, and may be a regular hexagonal column or a regular dodecagonal column.
Further, examples of the material of the ball box (101) include, but are not particularly limited to, wood and thermoplastic resin.

One side wall (2) of the eight side walls forming the side surface of the regular octagonal column has a discharge hole (21) large enough to eject one ball (S) at a time. Two are arranged side by side in the direction (arrow h direction in the figure).
In the present embodiment, the number of discharge holes (21) is two, but is not limited to this, and may be three or more. However, if too many balls (S) are discharged at one time, it is difficult to find out if the person who performs the lottery makes a fraud such as changing the discharged balls (S). Two to four are preferable.
Moreover, although the shape of the discharge hole (21) is circular in FIG. 1, it is not limited to this, For example, a rectangle etc. may be sufficient.

  The lottery machine (100) rotates the ball box (101) by rotating the handle (105) in the direction of the arrow θ in the figure (hereinafter referred to as the rotation direction in the present specification), and the discharge hole (21 ) From the ball (S).

  Here, since the ball box (101) has two discharge holes (21), two balls (S) can be discharged two by one, so that the lottery time can be shortened even when the number of lotteries is large.

In addition, by ejecting two balls (S) at a time, even if the type of the color of the ball (S) is limited, the grade of the lottery result can be determined by the combination of the colors of the balls (S) that have come out. So you can increase the types of prizes.
For example, 10 combinations are possible when there are four kinds of balls (S), and 15 combinations are possible when there are five colors.
The number of the discharge holes (21) may be three or more. When the number of discharge holes (21) is n and there are m kinds of balls (S) (m ≧ 2), {(n + m−1) )! } / {N!・ (M-1)! } Street combinations are possible.

FIG. 2 is a schematic diagram showing the internal structure of the lottery machine according to the present invention and is a view taken along the line AA in FIG.
FIG. 3 is a partial schematic cross-sectional view of the lottery device according to the present invention and is a view taken along the line BB in FIG.
FIG. 4 is a partial schematic cross-sectional view of the lottery device according to the present invention and is a view taken along the line CC in FIG.

As shown in FIGS. 3 and 4, the lottery machine (100) according to the present invention has an inner wall (3) parallel to the side wall (2) inside the side wall (2) where the discharge hole (21) is located. The gap (G) through which only one ball (S) (not shown in FIGS. 2 to 4) can pass is provided between the side wall (2) and the inner wall (3). . On the inner wall (3), a guide hole (31) having a size that allows only one ball (S) to pass therethrough coincides with the discharge hole (21) in the height direction (h direction) of the regular octagonal prism, and in the rotational direction. Two are provided at positions that do not match.
In FIG. 3, the guide hole (31) is provided at a substantially central portion in the rotation direction of the inner wall (3), but is not particularly limited.

A slide plate (4) is disposed in the gap (G).
FIG. 5 shows a perspective view of the slide plate (4).
As shown in FIGS. 4 and 5, the slide plate (4) is a rectangular plate having a thickness slightly smaller than the gap (G), and a through-hole having a size that allows only one ball (S) (not shown) to pass therethrough ( 41).
The slide plate (4) slides in the rotation direction (direction along the side wall (2)) in the gap (G), and the through hole (41) communicates with the discharge hole (21) at the rear stroke end thereof. At the front stroke end, the through hole (41) communicates with the guide hole (31).
The material of the slide plate (4) is not particularly limited. For example, thermoplastic resin such as acrylic resin, wood, or the like is used.

The number of guide holes (31) and the number of through holes (41) are two in this embodiment. However, the number of guide holes (31) and the number of discharge holes (21) may be the same as the number of discharge holes (21). In any case, the number is 3 and if there are n discharge holes (21), the number is n.
Moreover, in this embodiment, although the shape of the guide hole (31) and the through-hole (41) is circular, it is not limited to this, For example, a rectangle etc. may be sufficient.

  As shown in FIGS. 2, 3, and 4, the guide hole (31) has a guide hole (from the front end in the rotation direction of the side wall (5) adjacent to the front of the side wall (2). 31), guide grooves (51) for guiding the balls (S) to the guide holes (31) with a width allowing only one ball (S) to pass therethrough are formed in two rows substantially parallel to the rotation direction. The ball box (101) has inclined portions (52) that are inclined downward from the bottom walls (1) on both sides toward the guide groove (51).

When the side wall (5) is positioned downward by rotating the ball box (101), the balls (S) accommodated in the ball box (101) gather above the side wall (5) and are collected by the side wall (5). The balls (S) gathered above are guided to the guide groove (51) by the inclined portion (52).
The balls (S) that have entered the guide groove (51) move in the guide groove (51) as the ball box (101) rotates, and enter one by one in each guide hole (31).
Since the guide groove (51) is located in front of the guide hole (31) in the rotation direction, when the ball box (101) is rotated, the balls (S) that gather in front of the guide hole (31) in the rotation direction are surely collected. It can guide to a guide hole (31).

As shown in FIGS. 2, 3 and 4, the guide groove having the same cross-sectional shape as the guide groove (51) and the inclined portion (52) is provided inside the inner wall (3) and behind the guide hole (31) in the rotation direction. It is preferable that (32) and the inclined part (33) are formed.
This is because the ball (S) positioned behind the guide hole (31) in the rotation direction can also be guided to the guide hole (31).

  In this embodiment, the guide grooves (51) and the guide grooves (32) are arranged in two rows. However, the number of the discharge holes (21) is the same as the number of the discharge holes (21) in the same manner as the guide holes (31). Three rows are formed in the case of n pieces, and n rows are formed in the case of n pieces.

  FIG. 6 is a diagram showing the ball (S) discharging operation, and FIG. 6 (a) shows a state when the ball box (101) rotates in the rotation direction and the side wall (2) approaches the lowermost part. FIG. 6B is a view showing a state in which the ball (S) is discharged from the discharge hole (21).

When the ball box (101) rotates and the side wall (2) approaches from the top toward the bottom, the slide plate (4) slides by its own weight and moves forward in the rotational direction.
As shown in FIG. 6 (a), when the slide plate (4) reaches the forward stroke end in the rotational direction, the through hole (41) communicates with the guide hole (31), and the ball (S ) Moves to the through hole (41).

When the ball (S) moves to the through hole (41), the next ball (S) in the guide groove (32) or the guide groove (51) then enters the guide hole (31).
Since only one ball (S) can pass through the gap (G) where the slide plate (4) is located, the through hole (41) is closed with the ball (S). At this time, the guide hole (31) The next ball (S) that has entered stops in the guide hole (31). When the slide plate (4) slides, the slide plate (4) closes the lower side of the guide hole (31), so that the next ball (S) stays in the guide hole (31).

When the ball box (101) rotates and the side wall (2) begins to rise beyond the lowermost part, the slide plate (4) begins to move backward in the rotational direction due to its own weight.
When the slide plate (4) reaches the forward stroke end in the rotational direction as shown in FIG. 6 (b), the through hole (41) communicates with the discharge hole (21) to discharge the ball (S).

As described above, the balls (S) housed in the ball box (101) are the same number as the discharge holes per rotation (two in this embodiment) by the slide plate (4). Separated and reliably discharged.
Moreover, when it rotates in the reverse direction of a rotation direction, a ball | bowl (S) is not discharged | emitted.

  As shown in FIGS. 2 and 4, the lottery machine (100) opens a part of the opening portion of the guide groove (51) (in the present embodiment, immediately adjacent to the guide hole (31)) by covering the opening portion. A ball shield (6) that closes the part is provided.

Hereinafter, the operation of the ball guard plate (6) will be described with reference to FIG.
FIG. 7 shows a state in which the guide groove (51) is filled with balls (S) when the boundary between the side wall (2) and the side wall (5) is located below, and FIG. When not having a board (6), FIG.7 (b) has shown the case where it has a ball-off board (6).

A large number of balls (S) are accommodated in the ball box (101), and the guide groove (51) is filled with balls (S) when the boundary portion between the side wall (2) and the side wall (5) is positioned below. Then, balls (S) that cannot fit in the guide groove (51) are stacked on the balls (S) in the guide groove (51), and a load is applied to the balls (S) in the guide groove (51).
At this time, if the ball guard plate (6) is not provided, a load is applied to the ball (S) over the entire length of the guide groove (51), and the guide groove (51) is formed as shown in FIG. The filled ball (S) may be stuck at both ends of the guide groove (51) and become clogged. Then, the balls (S) do not fall into the guide holes (31), and the same number of balls (S) as the number of the discharge holes (21) may not be reliably discharged every rotation.

  If the ball guard plate (6) is provided, the ball (S) cannot enter the guide groove (51) from the position of the ball guard plate (6), and is located in the guide groove (51) at that portion. No load is applied to the ball (S), and a space (R) is formed between the ball (S) in the guide groove (51) and the ball guard plate (6) as shown in FIG. 7 (b). Therefore, the ball (S) in the guide groove (51) can move at the portion where the ball guard plate (6) is located, and the ball (S) in the guide groove (51) is clogged and becomes in the guide hole (31). The number of balls (S) equal to the number of the discharge holes (21) can be reliably discharged at the same time every rotation without entering.

  The present invention can be used for a rotary lottery machine, a bingo game machine, and the like used for lucky draw.
