See full text

An electronic device that has a secondary battery and a controller which receives power supply from the secondary battery so as to perform a drive control on one or other multiple circuits driven by receiving the power supply from the secondary battery includes an initializing unit that starts processing for outputting an initializing signal to instruct the controller to perform initializing at predetermined timing, in response to a starting point in which a voltage of the secondary battery becomes equal to or lower than a first threshold voltage which is set to be higher than an operation-guaranteed voltage of the controller and a lower state thereof continues for a predetermined period of time.
