PURPOSE:To substantially halves power consumption at the time of stand-by without increasing the cost significantly. CONSTITUTION:In a machine comprising a waiting power supply means for deriving a stand-by power supply from an AC input power supply and driving a remote control power supply, and a driving power supply means for deriving a driving power supply from the AC input power supply and driving a load set, a main power switch SW2 is arranged between the output side of the stand-by power supply and the remote control power supply and a timing generating circuit 12 for detecting the open/close state of the power switch SW2 is provided in parallel with the power switch SW2. |
