PROBLEM TO BE SOLVED: To provide a file by which a document can be simply arranged or classified to be stocked and at the same time the document can be readily bound without considering the space for the thickness of a binding tool even for the small number of document papers. SOLUTION: Either the rear cover or the front cover of a file is provided with a notch, allowing the part created by the notch to be used as a stopper to bind the document. Furthermore, the closed section of the file lower part is provided with a perforation, allowing the cut-off section to be used as a stopper to bind the document. COPYRIGHT: (C)2005,JPO&NCIPI
