1. An electronic device comprising:
a connecting unit connected to a connection line from which an electric power of a predetermined rating is supplied to the electronic device and via which the electronic device transmits and receives an information; a power circuit conducting a charging of a charging battery built within the electronic device, using a first amount of the electric power supplied by the connection line; an interface supplying a second amount of the electric power supplied to an operation of a recording medium storing an information, the interface performing a reading-and-writing operation of the recording medium; an electric source controlling unit:
allocating a portion of the first amount of the electric power supplied to the second amount of the electric power when it is required based on the second amount of the electric power supplied;reducing an electric power required for operating the recording medium from the electric power supplied to the power circuit in a case where the recording medium is built within the electronic device and reducing a maximum value of the electric source of a standard of the recording medium from the electric power supplied to the power circuit in a case where the recording medium is capable of attaching to and detaching from the electronic device, when the interface performs the reading-and-writing operation of the recording medium according to an access request to the recording medium via the connection line; andturning off an electric source after a predetermined time has elapsed from a later time of a time when the charging has been completed by the power circuit or a time when the reading-and-writing operation has been completed by the interface after the charging has been completed.
