<p>The present invention relates to a device for randomly extracting balls for a bingo game or lotto on which a number is marked and for proceeding various kinds of games by using the numbers marked on the balls. The device for randomly extracting balls includes a hollow casing through which upper and lower openings are formed coaxially; an opening and closing unit including a door opening and closing the lower opening of the casing and a first driving motor moving the door inside the casing to the left and right sides; a lifting unit including a lifting lever lifting one ball inside the opening of the casing to the upper side of the casing and a second driving motor rotating the lifting lever; and a movement control unit including a transverse lever limiting the upward movement of the ball to make one ball to be positioned inside the opening by temporarily blocking the upper opening of the casing, allowing one ball to move toward the upper side of the casing by opening the upper opening, and preventing the reverse downward movement of the ball by blocking the upper opening after the ball is moved toward the upper side of the casing. The transverse lever of the movement control unit is moved left and right sides by being interlocked with the operation of the second driving motor of the lifting unit, thereby moving the balls to the upper side in sequence via the casing and enabling the numbers marked on the balls to be extracted.</p> |
