ABSTRACT:
An original cover closer has first and second parts for supporting the cover on a main body of office equipment. The first part supports a heavier side of the cover and a second part supports the lighter side of the cover. Both parts have a mounting member with a bottom plate mounted on the main body and a first supporting member having a top plate and side plates extending downwardly, and rotatably mounted via a hinge pin at respective ends of the mounting member. A first lifting member is mounted via a second hinge pin at respective ends of the top plate so that the first lifting member is rotatable in a reverse direction to the first supporting member. A resilient member rotationally urges the cover in an opening direction by applying force toward the first supporting member and applying force on another end toward the first lifting member. A second lifting member is mounted via a fourth hinge pin at respective ends of the top plate so that the second lifting member is rotatable in a reverse direction with regard to the second supporting member. A torsion spring wound around the fourth hinge pin and rotatably urging the second lifting member toward such direction that it overlaps the second supporting member, by engaging an end on a lower surface of the top plate of the second supporting member and other end on an end surface portion toward the fourth hinge pin of the top plate of the second lifting member. The torsion spring is involved when the second lifting member is rotated in the reverse direction.
