PROBLEM TO BE SOLVED: To provide an inter-island ball transfer system having an upper tank with unified structure to be used in common when balls are transferred between two island blocks.SOLUTION: The number of Pachinko balls stored in base tanks B in two island blocks SB1, SB2 is controlled by controlling a shutter device for regulating flow-down of Pachinko balls in transfer gutters 2a, 2b between blocks. An upstream part of the transfer gutters 2a, 2b between blocks is connected to the other island replenishment passage of a sub-Pachinko island unit A4 in one island block, while a downstream part of the transfer gutters 2a, 2b between blocks is connected to a second reception passage of the sub-Pachinko island unit A4 in the other island block. An upper tank with unified structure can be used in common even when balls are transferred between the two island blocks SB1, SB2. |
