ELECTRONIC APPARATUS

A power-supply connection portion connects a power supply and a main body device. Operation information for operating the apparatus main body is stored in a volatile memory. A power feeder feeds power fed from the power supply, to the volatile memory. A non-operation state request receiver receives a non-operation state request for moving the apparatus main body from an operation state to a non-operation state. When the non-operation state request is received by the non-operation state request receiver, a power-feeding controller performs control such that the power feeder feeds the power to the volatile memory for a predetermined period. A mode determiner determines a mode of the non-operation state request. A changer is provided with a setter which sets the predetermined period depending on the mode determined by the mode determiner.
