System method for detecting a type of device wherein a potential level of the device determines if power should be supplied based on the type of the device

摘要

A small-sized connecting appliance is provided. An electronic appliance includes: a connecting section including a power-supply terminal and a connecting terminal to be connected to a connecting appliance; a detecting section that detects the potential of the connecting terminal; a power source control section that starts supplying power via the power-supply terminal; and an appliance recognizing section that recognizes the type of the connecting appliance based on the result of detecting the potential of the connecting terminal after the power supply start. A computer readable medium causes a computer to perform: detecting the potential of a connecting terminal connected to a connecting appliance; starting power supply via a power-supply terminal included in a connecting section that connects to the connecting appliance; and recognizing the type of the connecting appliance based on the result of detecting the potential of the connecting terminal after the power supply start.
