Abstract

A flexible electronic apparatus includes a housing, a roller received in the housing, and a main body wound around the roller. The roller is coupled to an end cover provided with a functional component. The roller is rotated relative to the end cover to expand or retract the main body. The end cover is provided with conductive rails electrically coupled to the functional component. The roller is provided with conductive terminals corresponding to the conductive rails. The conductive terminals are slidably connected to the conductive rails and slide along the conductive rails as the roller rotates.
