ELECTRONIC DEVICE

PROBLEM TO BE SOLVED: To provide an electronic device capable of supplying power to individual external devices so as to improve convenience for a user when two external devices are connected to an interface to which power can be supplied.SOLUTION: When a first device having a battery and a second device are connected to a USB interface (S12: YES) and the second device also has a battery (S14: YES), it is determined whether or not the sum of a charge amount C1 of the battery of the first device and a first predetermined amount Cx is equal to or less than a charge amount C2 of the battery of the second device (S15). Then, when the sum of the charge amount C1 and the first predetermined amount Cx is equal to or less than the charge amount C2 (S15: YES), the ratio of power supplied to the first device to power supplied to the second device is increased to be larger than the ratio of the power supplied to the first device to the power supplied to the second device when the sum of the charge amount C1 and the first predetermined amount Cx is larger than the charge amount C2 (S16).SELECTED DRAWING: Figure 2 【課題】２個の外部機器が電力供給可能なインタフェースに接続された場合に、ユーザにとっての利便性が向上するように、各外部機器に電力を供給できる、電子機器を提供する。【解決手段】バッテリを有する第１デバイスと第２デバイスとがＵＳＢインタフェースに接続され（Ｓ１２：ＹＥＳ）、第２デバイスもバッテリを有する場合（Ｓ１４：ＹＥＳ）、第１デバイスのバッテリの充電量Ｃ１と第１所定量Ｃｘとの和が第２デバイスのバッテリの充電量Ｃ２以下であるか否かが判別される（Ｓ１５）。そして、充電量Ｃ１と第１所定量Ｃｘとの和が充電量Ｃ２以下である場合（Ｓ１５：ＹＥＳ）、第２デバイスへ供給される電力に対する第１デバイスへ供給される電力の割合が、充電量Ｃ１と第１所定量Ｃｘとの和が充電量Ｃ２よりも多い場合における第２デバイスへ供給される電力に対する第１デバイスへ供給される電力の割合よりも増やされる（Ｓ１６）。【選択図】図２
