PROBLEM TO BE SOLVED: To provide a chair eliminating a wasteful cost that, when no customer uses a game machine, the power supply of the game machine is left turned-on. SOLUTION: The power supply of the game machine is turned on when the customer sits on the chair and, when the customer leaves there, the power supply is turned off when a set time comes. This constitution can save the electricity expense. COPYRIGHT: (C)2005,JPO&NCIPI
