Hinge structure for mounting a cover onto an electronic device

摘要

A scanner uses a hinge to connect the cover and the scanner body. The scanner further comprises a brake apparatus and a force-dispersing mechanism. The brake apparatus interferes the lifting cover at a predetermined interfering angle for avoiding the cover to thump at the scanning surface. The force-dispersing mechanism is used to disperse a stress resulted from the cover is lifted to be over a predetermined safety angle with respect to the scanning surface of the scanner.
