Abstract

PURPOSE: To prevent the power from being supplied again at a restoration time after power failure by supplying the power from a main power source circuit to a load and supplying the power from an auxiliary power source circuit to a remote control receiving circuit, etc.
CONSTITUTION: When main power source switch 5 is closed, an auxiliary power is generated from auxiliary power source circuit 4. However, since bistable circuit 11 becomes an initial reset state at this time, auxiliary power source switch 6 continues to open, and image receiving circuit 8 is not operated. When a power source switching signal is generated from a remote control transmitter under this state, bistable circuit 11 becomes a set state, and auxiliary power source switch 6 is closed to supply the main power to image receiving circuit 8, and the operation is started. Thus, since auxiliary switch 6 to supply the power to image receiving circuit 8 is not closed until main power source switch 5 is closed and the remote control signal, etc., are generated, the power can be prevented from being supplied again at a restoration time after power failure.
