PROBLEM TO BE SOLVED: To provide an island interchange-type game ball transfer apparatus capable of preventing a partition board from breaking off with a pressure difference of Pachinko game balls in a structure in which two kinds of the balls are stored without being mixed respectively by providing the partition board inside a base tank. SOLUTION: A stock amount of golden balls stored inside a golden ball-storing space 33a of the base tank B1 is compared with that of silvery balls stored inside a silvery ball-storing space 33b of the base tank B1. When there is a difference of at least a specified amount, a control for interchanging the golden balls between a side of the space 33a of the base tank B1 and that of a base tank B2 is conducted so that the stock amount of the golden balls inside the space 33a is approximately equal to that of the silvery balls inside the space 33b. Thus, the board 34 can be prevented from breaking off by pressures of the Pachinko game balls stored inside the spaces 33a and 33b. COPYRIGHT: (C)2011,JPO&INPIT
