Portable electronic device e.g. laptop, mobile phone, PDA, has off-centering device to regulate movement between base and cover, biaxial mechanism placed normal to plane of hinge height to bisect angle formed by base and cover

摘要

The device has a base equipped with a keyboard and a hinge to move a cover by a rotational movement with respect to the base. A height of the hinge extends in a direction of a total of a thickness of the base and cover. A biaxial mechanism (32) that is normal to a plane of the height bisects an angle formed by the base and cover. An off-centering device (31) regulates the movement between the base and cover.
