<P>PROBLEM TO BE SOLVED: To provide a rotating device that has a small number of components and facilitates opening and closing operations of a portable electronic device and a portable electronic device that uses the rotating device. <P>SOLUTION: The rotating device of the present invention comprises a coupling unit, a first contact stop component and a second stop component that are slidably attached to opposite ends of the coupling unit respectively, elastic assemblies that are respectively attached to the first stop component and the second stop component. When one end of the rotating device is rotated by an external force around an end of the first stop component as a rotation axis, the first stop component and the second stop component move opposite to each other while storing an elastic force in the elastic assemblies. After the rotating device is rotated by a predetermined angle, the first stop component and the second stop component are bounced in opposite directions by the force of restitution of the elastic assemblies while automatically rotating around the end of the first stop component as a rotation axis. <P>COPYRIGHT: (C)2012,JPO&INPIT |
