PROBLEM TO BE SOLVED: To securely prevent clogging with game balls in an out-ball collection box for collecting game balls discharged from a game machine and discharging the collected game balls into a lower tank in a game machine island for feeding game balls to the game machine by inclining the bottom of the lower tank downward toward a ball lifting device and lifting game balls inside the lower tank by the ball lifting device. SOLUTION: The lower tank 31 has inclined projecting stripes 65 and 66 which project from both side walls and which are inclined in the direction opposite to the bottom 34, and an inclined gutter 81 which is formed at the intermediate position apart from the inclined projecting stripes 65 and 66 and in the same direction of inclination as the bottom 34. Game balls are guided from outside into the lower tank 31 by the inclined projecting stripes 65 and 66, and if a number of balls are stored in the tank, the game balls to flow down into the lower tank 31 are bypassed through the inclined gutter 81 and fed to the ball lifting device 33. Positioning members 91 and 92 having spaces penetrating in the vertical direction are located between the inclined projecting stripes and the inclined gutter, and ball outlets 53a and 54a of the out ball collection box are inserted into the spaces of the positioning members.
