First Claim
1. A hinge apparatus to open and close a cover of an image forming apparatus, which pivotably connects the cover to a main body of the image forming apparatus, to expose and cover a document glass, the hinge apparatus comprising:
- a hinge body movably inserted in a first direction into a coupling hole positioned in the main body of the image forming apparatus, and having supporting brackets;
a hinge cam, connected to the cover, and pivotably connected to the supporting brackets; and
a pressure device disposed at the hinge body to press the hinge cam;
the hinge body is provided with a housing chamber; and
the pressure device comprisesa pusher disposed in the housing chamber, that protrudes from the housing chamber, anda spring disposed within the housing chamber to press the pusher;
the pusher comprises a locking protrusion;
the hinge body is provided with a guide slot; and
the locking protrusion is inserted into the guide slot, and prevents the release of the pusher from the hinge body;
wherein the pusher moves upward and downward within the guide slot.
