摘要

PURPOSE: Accessories of an electronic device are provided to display an upper side and a lower side of a body with light, thereby distinguishing the upper side and the lower side of a connection port. CONSTITUTION: A body comprises a circuit substrate. A connection port(103) capable of connecting and separating with an electronic device is mounted on the body. A light source(122) is connected to the circuit substrate. The connection port outputs light in a state of being separated from the electronic device. A display unit(110) displays an upper side and a lower side of the body using the light. The light source outputs the light by contacting one side of the body. A sensing unit(123) is formed on one side of the body.
