Abstract
An electronic apparatus includes a control portion, a signal output circuit, a switching processing portion, and a determination processing portion. The control portion switches on or off power supply from the primary power source in response to detection of an operation on a power switch. The signal output circuit outputs a preset digital signal. The switching processing portion switches a signal level of the digital signal when a power supply state of the control portion is switched. The determination processing portion determines whether or not to execute power supply to the control portion based on the signal level of the digital signal output by the signal output circuit when power supply from an external power source to the primary power source is started.
