PROBLEM TO BE SOLVED: To provide a ball introduction stopping mechanism for a pachinko ball pumping-up device capable of preventing introduction of pachinko balls into a ball inflow port by surely stopping pachinko balls rolling from left and right collecting gutters with a simple mechanism not having an electrical constitution (solenoid and electrical parts) and therefore without failure factors. SOLUTION: The pachinko ball pumping-up device is placed approximately at the center of the game machine island having a plurality of game machines, makes pachinko balls flow down from the collecting gutters through the ball introducing aligning gutter and polishes and pumps up the pachinko balls. The balls flowing down from the left/right collecting gutters are inhibited from entering the introducing aligning gutter by raising both side walls of a ball introductory tilting plate to a position higher than the bottom face of the collecting gutters, and are permitted to enter the introducing aligning gutter by lowering the side walls of the tilting plate to a position lower than the bottom of the collecting butter. In operation of the above inhibition and permission, the tip end of the operation lever is brought into contact with the rear face of the tilting plate to interlock the tilting plate with the movement of the operation lever.
