Abstract:
1. An electronic apparatus comprising: an enclosure that is a casing; submergence detector for detecting submergence of the electronic apparatus including a situation where the electronic apparatus has been dropped and stays afloat on the water surface and a situation where the electronic apparatus has been dropped and stays underwater as well as a situation where the electronic apparatus has been retrieved from the water; a light-emitting device that emits light; an illumination circuit for lighting the light-emitting device when an illumination signal is input; a controller for making the light-emitting device blink by generating the illumination signal at prescribed blinking intervals at least during a period from a point of submergence to a point of retrieval of the electronic apparatus and inputting the illumination signal to the illumination circuit; a battery that supplies electric power, and a power control circuit for activating the controller by supplying the electric power thereto from the battery when the submergence detector detects submergence, wherein the submergence detector, the light-emitting device, the illumination circuit, the controller, the battery and the power controller circuit are equipped with the enclosure.
