<P>PROBLEM TO BE SOLVED: To provide an electronic device which surely shuts down electricity supply to whole device when power source is cut off, while suppressing electric power consumption. <P>SOLUTION: An electronic device includes an AC/DC converter 101, a first capacitor C1 and a sleep CPU91. The electronic device also includes a first switch 102 which is connected between the AC/DC converter 101 and the first capacitor C1, and electrically connects or disconnects the AC/DC converter 101 and the first capacitor C1 based on control of the sleep CPU91. The electronic device further includes a second switch 103 which is connected between the first capacitor C1 and the sleep CPU91. The second switch 103 electrically connects the first capacitor C1 with the sleep CPU91 when direct current voltage is outputted from the AC/DC converter 101 and electrically disconnects the first capacitor C1 from the sleep CPU91 when direct current voltage is not outputted from the AC/DC converter 101. <P>COPYRIGHT: (C)2013,JPO&INPIT |
