Description

  The present invention relates to a variable winning device used in a pachinko machine.

  The symbol variation display on the symbol variation display device is started by winning the ball at the start winning opening, and a special game that is advantageous to the player, the so-called “big hit” state, is generated when the symbols at the time of variation stop are aligned with the predetermined symbol. As a prize-winning device used in a pachinko machine, which is called a right object that gives an opportunity to be used, a rotating body type prize-winning device is often used. The rotating body type winning device is provided such that a rotating body formed with a hollow ball holding portion capable of accommodating one game ball on the outer peripheral surface is always rotated in a fixed direction by driving a motor. It is set as the structure which provided the ball | bowl entrance in the upper part of the annular member formed so that it might surround. Then, when the ball holding portion coincides with the ball entrance, the game ball waiting at the ball entrance is received by the ball holding portion and rotated downward, and is disposed immediately below the discharge port provided at the lower portion of the annular member. It is provided to win the starting prize opening.

  In the above rotating body type winning device, it is possible to reliably control the winning of each game ball one by one. However, since the waiting time from the game ball to winning is controlled by the rotational speed of the rotating body, for example, the rotational speed of the rotating body If the game is constant, there will be no denying that the game after the right of winning the jackpot will be monotonous, and there will be a problem that the utilization rate of the pachinko machine will decrease due to a strategy such as a stop-attack aiming for winning according to the rotation speed .

Accordingly, the present invention has developed a so-called tulip-type variable winning device that is different from the rotating body type in order to eliminate the problems found in the rotating body type winning device.
