Abstract

See full text

The invention provides for 'windowing' leafs of various types which retain their face and perimeter orientation when repositioned with respect to their host binder, including leafs with pluralities of surfaces, leafs with arrays of stacked repositionable notes, leafs and notepads, leafs with arrays of clips, and the like. The invention further provides for the binding of leafs which themselves may be electronic modules, each acting as a means for one of capturing, storing, accessing, displaying, and transmitting information in electronic form. Further, binding system cover is provided which offers a ring binding mechanism that is simple, light weight, and of a closed loop design available in various application specific shapes. Leaves and mounting surfaces according to the invention provide semi-permanent retaining means which enable easy removal and reinsertion, permitting rapid reordering, while retaining their semi-permanent binding during the page turning operation, independent of the weight of the mounting surface, any force orthogonally inward or outward with respect to the host coupling structure, and any position it may take in turning as it twists over its coupling structure, and to book systems formed by combining covers, rings, and mounting surfaces according to this invention that offer compact, reconfigurable, highly visual means for handling heterogenous, mixed media forms of information.
