Abstract
A hinge apparatus employs a base, a second base, link arms, urging means and the characteristics of a parallelogram formed by the shape of said base, second base and paired link members to enable a body such as a platen cover to rotate up open and lower substantially parallel to an original platen and to enable the parallel opening of the body thereby ensuring the complete covering of a thick original or a book original placed upon the clear glass platen enabling good quality copies of the original regardless of its thickness.
