Abstract:
When an electronic apparatus comes to a state of being capable of receiving electric power, an output voltage of an AC adaptor changes from a second voltage Vb to a first voltage Va and the change in voltage can be detected by an electronic apparatus. Due to this configuration, a structure that can detect the type of AC adaptor can be provided without adding any new contacts to a DC input terminal and to a DC output terminal.
