<P>PROBLEM TO BE SOLVED: To solve the problem that an electronic apparatus may require a large-scaled and expensive power supply unit, which is capable of singly supplying maximum power consumption, with usual adverse conversion efficiency. <P>SOLUTION: An electric apparatus 101 includes: an apparatus body 110 consuming power; a power supply unit 120 for supplying power from a commercial power source to the apparatus body 110; a secondary battery 130 which is charged with power supplied from the power supply unit 120; and a power supply control section 140. When used power of the apparatus body 110 exceeds a first threshold value in the state where a power supply source of the apparatus body 110 is the power supply unit 120, the power supply control section 140 changes to the state where the power supply source of the apparatus body 110 becomes the power supply unit 120 and the secondary battery 130. <P>COPYRIGHT: (C)2012,JPO&INPIT |
