PROBLEM TO BE SOLVED: To provide a power supply control device capable of restoring an on/off state a device was in before power was cut off without activation of software, even when supply of power resumes after being in a power outage condition with the supply of power thereto cut off.SOLUTION: A nonvolatile memory 54 has a function that allows for outputting a bit logic state stored in a specific area therein as a state-holding signal 101 representing an on/off state a device main body 40 was in before power was cut off. A CPU 53 controls the on/off state of the device main body 40 and writes the on/off state of the device main body 40 into the specific area of the nonvolatile memory 54. A logic circuit comprising an OR circuit 60, an AND circuit 61, and a buffer circuit 62 provides control such that power is supplied to the CPU 53 by controlling a DC/DC converter 51 based on the logic of the state-holding signal 101 from the nonvolatile memory 54. |
