Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention selects a number on a ball by randomly picking out a numbered ball from a container and selecting the number on the ball during a bingo game. TECHNICAL FIELD The present invention relates to a number selection machine for a bingo game, in which a ball can be easily taken out from a container and a motion during driving is dynamic, which makes the game more exciting and interesting.

[Conventional technology]

In the bingo game, the player has cards with different combinations of numbers written, and the numbers are selected one after another from the number selection device in public, and the numbers are arranged in a line in one's own card earlier than others. It is a game that wins the person who matches the five numbers. Primitively, a box with a number on it was used as a number selection device of this kind, and the player squeezed this box and threw a ball or arrow into the box to select a number. In, various number selection machines have been developed.

All of these number selectors put a large number of balls with numbers written in a closed container with a hole in the top, put this ball on the tip of a ball picking rod that pushes up from the bottom of the container, and take it out from the hole in the top, It has a structure to read the number written on the ball.

[Problems to be solved by the invention]

However, in the number selector having the above-described structure, when the ball is taken out, the ball take-out rod moves vertically from the bottom surface to the hole direction of the top with the ball placed on the tip, so the ball easily falls from the tip, and therefore, from the container. It becomes difficult to remove the balls.

Also, when removing balls, the container itself remains stationary, and the ball removing rod only moves inside the container, so there is no dynamic feeling during driving, and thus lack of dynamicness, so the game does not excite , I'm not so interested.

Therefore, the purpose of the present invention is to move the container up and down while keeping the ball ejecting rod stationary, which facilitates the ejection of the balls from the container and makes the operation during operation dynamic. It is an object of the present invention to provide a number selector for a bingo game in which the game is more exciting and interesting, and the above-mentioned drawbacks in the known art are improved.

[Means for solving problems]

In order to achieve the above-mentioned object, according to the present invention, a container having a lid and a bottom plate for holding a large number of balls with numbers therein, and a bottom plate of the container is inserted, and a ball mounting surface is provided at the tip. A support rod, a ball take-out opening is formed at the top of the lid, a stirring blade is attached to the inner surface of the bottom plate, and a ring gear is attached to the outer surface of the bottom plate. The bottom plate is configured to be rotatable by means of which a vertical gear is mounted on the side wall of the support rod in the longitudinal direction, and the reversing gear meshing with the vertical gear supports the container to be vertically movable along the side wall on the support rod. It is characterized by being done.

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a specific example of a number selector according to the present invention, FIG. 2 is a sectional view of FIG. 1 in a non-operating state, and FIG. 3 is a bottom plate of the present invention. It is a top view.

In the figure, 1 is a container, which has a lid 2 and a bottom plate 3, in which a large number of balls 4, 4 ...
4 is held. A ball take-out port 5 is bored on the top of the lid 2, and an arbitrary number of, for example, two stirring blades 7 are attached to the inner surface 6 of the bottom plate 3, and a ring-shaped member is provided almost at the center of the outer surface 8. The gear 9 is mounted. Further, a rotary gear 10 is meshed with the ring-shaped gear 9 and the motor 10
The rotary gear 10 is rotated by transmitting the rotary power of 11 via the transmission gears 12, 13 and 14, and the bottom plate 3 is rotated by this rotary power.

A support rod 18 is inserted through the bottom plate 3 of the container 1 to support the container 1. The support rod 18 has a ball mounting surface 19 at its tip, and a vertical gear 21 is mounted on a side wall 20 in the longitudinal direction. Further, a reversing gear 22 is meshed with the vertical gear 21, and the revolving power of the motor 11 is transmitted to the reversing gear 22 via the transmission gears 12 and 13 and the fan gear 23, so that the reversing gear 22 is anti-rotationally rotated. Thereby, the container 1 moves up and down along the side wall 20. The fan gear 23 has a gear 25 at the position of the arc 24.
And has an elongated hole or groove 27 along the radial direction from the end 24a of the arc 24 to the fulcrum 26, and is pivotally supported by the shaft 29 at the fulcrum 26 so as to be rotatable left and right. The gear 25 is connected to the reversing gear 22 via the transmission gear 30, and the transmission gear 13
The pin 28 provided in the hole is fitted in the hole or groove 27, and as a result, the reversing gear 22 includes the transmission gear 30, the sector gear 23, and the transmission gear 1.
It is in communication with the motor 11 via 3, 12. At this time, in the transmission gear 13, the pin 28 is moved up and down along the hole or groove 27 along with this rotation, and this vertical movement gives the fan gear 23 a lateral rotation motion, and this lateral rotation motion is further reversed by the transmission gear 10 and the reversing motion. The gear 22 is given a reversing motion, which allows the container 1 to move up and down along the side wall 20.

[Action]

In the present invention having the above-described structure, when the button 16 of the board 15 is pressed as shown in FIG. 4, the switch 17 is pressed by the pressing piece 31 to be turned on and the motor 11 is rotationally driven. Then, the rotational power of the motor 11 is transmitted to the rotary gear 10 via the transmission gears 12, 13, 14 to rotate the bottom plate 3 of the container 1. By this rotation, the stirring blade 7 on the inner surface 6 starts to move to stir the balls 4, 4 ... 4 in the container 1.

At the same time, the rotational power of the motor 11 is transferred to the transmission gears 12, 13
Is transmitted to the fan-shaped gear 23 via the transmission gear 30 and is rotated to the left to rotate the reversing gear 22 via the transmission gear 30 to move the container 1 downward as shown in FIG. At this time, the pressing piece 33 of the second switch 32 separates from the second switch 32 and is turned on (see FIG. 5), and as a result, the motor 11 is driven by the first and second switches.
Both switches are turned on. When the fan-shaped gear 23 is rotated fully to the left, the container 1 moves to the fifth position.
As shown in the figure, the lowermost position is reached, at which time the lower end portion 34 of the container 1 lowers the pressing piece 35 and presses the pressing piece 31.
Although the switch 17 is turned off, the second switch 32 holds the ON state, so that the rotational driving of the motor 11 is not stopped.

In the present invention, since only the container 1 descends and the support rod 18 does not move, one ball 4 is left on the ball mounting surface 19 at the tip of the support rod 18 as the container 1 descends, and then the container 4 is placed. When 1 reaches the lowest position, the balls 14 on the ball placing surface 19 are pushed out from the ball take-out port 5.

Then, when the sector gear 23 turns rightward, the transmission gear 30 reversely rotates, and at the same time, the reverse gear 22 also reversely rotates, and the container 1 is moved upward as shown in FIG. When the container 1 reaches the highest position when the container 1 is fully rotated, the second switch 32 is pressed by the pressing piece 33 to be turned off, and only one ball 4 is randomly placed on the ball take-out port 5. The operation stops when it is taken out.

[Effect of device]

As described above, according to the present invention, the balls in the container can be taken out from the ball mounting surface at the tip of the supporting rod at the ball taking-out port by moving only the container downward while the supporting rod is stationary. Seldom falls off the loading surface, thus facilitating removal of the ball from the container. Furthermore, the present invention is a very useful idea in practice because the operation during driving is dynamic because the container moves up and down while the bottom plate rotates, which makes the game even more exciting and interesting.
