PROBLEM TO BE SOLVED: To suppress the generation of the sound of reporting by a reporting means provided in each game machine island and to improve the work efficiency of work staff. SOLUTION: When receiving a control instruction signal from management terminal device 2 installed in a place away from the game machine island 100, an island control unit 5 controls game ball circulation facilities (reduction machine 200, heater 220 and ball discharge stopper 230, etc.,) on the basis of the control instruction signal. When the island control unit 5 receives the control instruction signal, the sound is outputted until the game ball circulation facilities is operated by a prior reporting device 9 installed to the game machine island 100. However, when a reduction machine door to be opened in the case of inspecting the reduction machine 200 is closed, the sound is not outputted from the prior reporting device 9 even when the control instruction signal is received. That is, for the game machine island 100 where the reduction machine door is closed and inspection work is not to be performed, the sound output is omitted since there is no need of the sound output by the prior reporting device 9.
