Abstract:
1. A hinge for use with an electronic device, the hinge comprising: a cam comprising a cam surface, which comprises a first sliding surface, a first stop surface, a second sliding surface and a second stop surface, wherein the first stop surface is located between the first and second sliding surfaces; a cam follower comprising at least one cam following tip arranged to contact the cam surface; a resilient member arranged to provide a force to urge the cam and the cam follower toward each other, thereby maintaining the contact between the cam follower and the cam; wherein one of the cam and the cam follower is rotatable about an axis, while the other is substantially non-rotatable about the axis; wherein the first sliding surface is configured to cause a first substantially spontaneous sliding of the at least one cam following tip thereon, which causes a first rotational movement of the rotatable member for a first angle about the axis in a rotational direction; wherein the first stop surface is configured to stop the first substantially spontaneous sliding of the at least one cam following tip within the first stop surface, which causes to stop the first rotational movement; wherein the second sliding surface is configured to cause a second substantially spontaneous sliding of the at least one cam following tip thereon, which causes a second rotational movement of the rotatable member for a second angle about the axis in the same rotational direction, wherein the first angle is substantially greater than the second angle; and wherein the second stop surface is configured to stop the second substantially spontaneous sliding of the at least one cam following tip within the second stop surface, which causes to stop the second rotational movement.
