PROBLEM TO BE SOLVED: To provide an opening/closing device for an opening/closing door opening/closing an alignment trough in a game ball lifting device, not causing hindrance to opening/closing of the opening/closing door, capable of suppressing failure of an opening/closing mechanism of the opening/closing door, and suppressing a cost of the alignment trough, and to provide the game ball lifting device therewith. SOLUTION: This opening/closing device has an automatic shutter 64 damming a flow of game balls flowing in the alignment through 62 in a prescribed position. An outer shape of the opening/closing door 64-5 in the automatic shutter 64 is formed in a nearly comb shape. When bringing the opening/closing door 64-5 into a closing state to dam the game ball, comb teeth 64-5b are projected above game ball routes 62-3 inside the alignment trough 62 upward from below to dam the flow of the game balls in the prescribed position. When bringing the opening/closing door 64-5 into an open state, the opening/closing door 64-5 is moved downward. The opening/closing of the opening/closing door 64-5 is executed by driving a motor unit 64-1. COPYRIGHT: (C)2003,JPO
