<P>PROBLEM TO BE SOLVED: To provide a method for stably driving an electronic device including a power supply circuit to which power is fed from a noncontact power feeding device and plural loads to which power is supplied sequentially from the power supply circuit, and to provide a method for stably driving an electronic device including a power supply circuit to which power is fed from a noncontact power feeding device and one or more loads to which power is supplied repeatedly from the power supply circuit. <P>SOLUTION: An interval for which a load is not connected to the power supply circuit is provided. After the power supply potential V<SB POS="POST">dd</SB>is recovered to 90% or more of the initial potential V<SB POS="POST">dd0</SB>, a next load is connected to the power supply circuit, so that driving is performed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
