<p><P>PROBLEM TO BE SOLVED: To effectively eliminate game balls getting easily stuck between a wall and an opened opening/closing door when a jackpot prize-winning device is disposed in a game area to the right of a game machine which allows for shooting game balls so that they may go to only the right side of the board and the wall is provided to prevent falling-off of game balls along the left edge of a jackpot prize-winning port. <P>SOLUTION: The jackpot prize-winning device 13 that is disposed corresponding to the jackpot prize-winning port that is formed in a lower right region of the game board surface comprises: a base member 36 provided with an opening 36A for prize winning; the opening/closing door 34 that opens and closes the opening for prize winning; an advancing and receding member 40 that is disposed to the left of the opening for prize winning so that it may advance and recede and guides game balls to the inside of the opening for prize winning in cooperation with the opening/closing door that is in an opened state. The advancing and receding member can advance and recede between a game ball stop position and a game ball release position. When a game ball stays between the inner surface of the opened opening/closing door and the advancing and receding member that is located at the game ball stop position and a pressure applied from the stayed game ball exceeds a predetermined value, the advancing and receding member recedes to the game ball release position. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
