Abstract

Abstract A compact three-leaf combination book prop and notepad. The three leaves are hinged end-to-end and fold closed in a flat "Z" orientation so as to be suitable for insertion in a breast pocket. Two of the leaves may be fixed in an inverted "V" orientation to give vertical support to a book. The third leaf includes a paper pad clip which also serves as a book catch for preventing horizontal slippage of the propped book. The front face of the center leaf includes a thin electronic computer and a holder for a flattened writing utensil.
