摘要

PROBLEM TO BE SOLVED: To provide a game parlor network system using a PLC (Power Line Communication) for performing stable communication even when many game machines are connected.;SOLUTION: A pre-branching port of a first branching adapter 15 is connected to a communication line connection port of a PLC master machine modem 13, a communication line connection port of a PLC relay device 16 is connected to a branched port of the first branching adapter 15, and a pre-branching port of a second branching adapter 7 is connected to a power line connection port of the PLC relay device 16 via a power line. Moreover, the communication line connection port of a PLC slave modem 9 is connected to the branched port of the second branching adapter 7 via the communication line and a game machine 8, such as a Pachinko machine, is connected to a terminal device connection port of the PLC slave machine modem 9. A master frame for transmitting data is provided with an emergency communication bandwidth, so that detection information, such as fraudulent practice detected in the game machine, is speedily transmitted to a server.;COPYRIGHT: (C)2010,JPO&INPIT
