ABSTRACT:
A microfiche reader has a carrier which includes means for transporting a microfiche film with a rectilinear movement. The carrier has two plates of glass for receiving a microfiche between them, one of the glass plates being hinged to raise and lower relative to the other. As the carrier moves to one extremity of its rectilinear movement, the cover glass automatically swings on its hinge pin to open and thereby enable manual access to the microfiche between the glass. Regardless of how far the carrier does or does not move, near the extremity of the movement, this glass opening device has an ability to lift the cover glass to a position where its center of gravity closely approaches, but does not cross, the hinge pin.
