Abstract
A hinge apparatus for a cover of an image forming apparatus has a hinge body with supporting brackets, movably inserted into a coupling hole positioned in a main body of the image forming apparatus, 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. Accordingly, the hinge apparatus can be implemented with a simple and easy assembly operation, since it is not a complicated structural connection among the component parts of the hinge apparatus.

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 comprises
- a pusher disposed in the housing chamber, that protrudes from the housing chamber, and
- a 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.
A hinge apparatus rotatably connecting a cover and a main body, the hinge apparatus comprising:
- a hinge body, with a void therein and a supporting bracket, movable in an opening in the main body;
- a pressure device, movable within the void, and biased toward a first end of the hinge body;
- and
- a hinge cam, connected to the cover, rotatably connected to the supporting bracket, and slidably engaging the pressure device;
- wherein the hinge body comprises a first protrusion, to limit an amount the hinge body moves into the opening in the main body.
A hinge apparatus rotatably connecting a cover and a main body, the hinge apparatus comprising:
- a hinge body, with a void therein and a supporting bracket, movable in an opening in the main body;
- a pressure device, movable within the void, and biased toward a first end of the hinge body, wherein the pressure device comprises a pusher;
- and
- a hinge cam, connected to the cover, rotatably connected to the supporting bracket, and slidably engaging the pressure device, wherein:
- a first protrusion and a second protrusion are provided on the hinge cam;
- and
- a first receiving part and a second receiving part, receiving the first and second protrusions respectively, are provided on the supporting bracket to rotatably connect the hinge cam and the supporting bracket.
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, the hinge apparatus comprising:
- a hinge body comprising a housing chamber and supporting brackets;
- a hinge cam pivotably connected to the supporting brackets;
- and
- a pressure device disposed at the hinge body to press the hinge cam, said pressure device comprising:
- a pusher comprising a guide member, disposed in the housing chamber;
- and
- a spring disposed in the housing chamber to press the pusher, wherein the hinge body is provided with a receiving member corresponding to the guide member to guide a movement of the pusher.
A hinge apparatus rotatably connecting a cover and a main body, the hinge apparatus comprising:
- a hinge body, with a void therein and a supporting bracket;
- a pressure device, movable in the void, and biased toward a first end of the hinge body;
- and
- a hinge cam rotatably connected to the supporting bracket, and slidably engaging the pressure device;
- wherein one of the hinge body and the hinge cam comprises a first protrusion, to limit an amount the one of the hinge body and the hinge cam moves into an opening in the main body.
