Sheet mounting apparatus

Abstract

The invention allows an amount by which restricting members should be moved to be grasped accurately and easily, prohibits movement of the restricting members in time of fastening the restricting members, and allows positions of the restricting members to be adjusted accurately and just by a necessary amount. A set screw is meshed with a boss of a retaining member through an eccentric cam mounted in a cam guide formed in an upper surface of a main body, the eccentric cam being supported to have an axis of rotation aligned to an axis of rotation of a pinion. A rotation of the eccentric cam varies positions of contact between peripheral surface of the eccentric cam and side surfaces of the cam guide to vary a distance from the positions of contact to the center of rotation of the eccentric cam.
