The present invention has been developed to solve the above problem and its object is to provide an original cover closer which has a simple structure and reduced cost and can increase the stability of the original cover during the opening and the closing to thereby improve its operability, and office equipment including the original cover closer. The present invention is an original cover closer including two types of a first opening/closing part of an original cover and a second opening/closing part of the original cover, for supporting the original cover to be opened and closed on a main body of office equipment, the original cover having a center of gravity shifted either to the right or to the left, the first opening/closing part of the original cover for supporting the original cover on the side to which the center of gravity is shifted, including a first mounting member mounted on the main body; a first supporting member axially supported to be rotatable on the first mounting member; a first lifting member overlapping the first supporting member, axially supported to be rotatable on a free end of the first supporting member, and mounted on the original cover; and a resilient means provided between the first mounting member and the first supporting member, for rotationally urging the original cover in a direction of opening and urging the first lifting member in a direction in which the first lifting member overlaps the first supporting member, and the second opening/closing part of the original cover for supporting the original cover on a side opposite to the side to which the center of gravity is shifted, including a second mounting member mounted on the main body and having two side plates opposed to each other; a second supporting member axially supported to be rotatable on both the side plates of the second mounting member via a first rotation hinge pin; a second lifting member overlapping the second supporting member and axially supported to be rotatable on free ends of the two side plates opposed to each other of the second supporting member via a second rotation hinge pin, and mounted on the original cover; and a torsion spring provided, wound around the second hinge pin, between the second supporting member and the second lifting member, for urging the second lifting member in a direction in which the second lifting member overlaps the second supporting member.
