A portable electronic device includes a base or first member, a flip or second member, and a hinge mechanism pivotally connecting the second member to the first member for pivotal movement between a closed position and an open position. The hinge mechanism includes a first semi-annular elongated recess and a semi-annular elongated concave member with a semi-annular elongated concave surface, the semi-annular elongated rotation member being pivotally and slidably disposed within the first semi-annular elongated recess, and the semi-annular elongated concave surface of the semi-annular elongated rotation member being exposed when the first member and the second member are in the closed position and being not exposed when the first member and the second member are in the open position.
