Abstract: An improved sheet holder having a substantially rigid base plate and a clamping member hingedly connected to the base plate along one edge thereof for clamping engagement with one edge of a sheet for securely maintaining same in position adjacent the upper surface of the base plate. A substantially channel-shaped hinge member is fixedly secured to the base plate and extends into substantially parallel slots formed in the clamping member for permitting relative pivotal movement therebetween. A leaf spring is disposed between the legs of the hinge member and is positioned to resiliently urge the clamping member toward an open or closed position. The hinge assembly, including the spring, is substantially hidden by the clamping member, even when in the open position.
