Abstract
Official abstract text for this publication.
A power supply control device includes an always powered section and a selectively powered section. The always powered section includes a switch determining whether or not to supply external power to the selectively powered section, a first memory circuit storing information for turning on/off the switch, and a second memory circuit storing information on a change in a main power supply switch. The selectively powered section includes a power supply circuit supplying power to the device body, a non-volatile memory configured to storing information on an on/off-state of the device body, and a control section changing the information in the first memory circuit in accordance with the information in the non-volatile memory and the second memory circuit.
First claim
