PROBLEM TO BE SOLVED: To suppress, even when instantaneous interruption has occurred to a power source to be supplied to an electronic apparatus such as a projection device, the electronic apparatus from being shifted to a stand-by state when the electronic apparatus returns from the instantaneous interruption.SOLUTION: An electronic apparatus 1 includes an electronic apparatus main body unit 50, a delay circuit that receives the input of the voltage of power supplied to the electronic apparatus main body unit 50 and delays the output of a voltage responding to the input voltage, a voltage detection IC 26 that compares the output voltage from the delay circuit with a predetermined threshold and outputs a result of the comparison, and a power source control microcomputer 13 that reads the result of the comparison by the voltage detection IC 26 at the start-up and starts the electronic apparatus main body unit 50 when the result of the comparison indicates that the output voltage is equal to or more than the threshold. |
