<P>PROBLEM TO BE SOLVED: To eliminate a defect that when paper is folded up manually, the folding widths may become uneven or bending may be caused, thus preventing the paper from being folded up finely. <P>SOLUTION: When paper is folded up using a paper folding auxiliary tool, one edge of the paper folding auxiliary tool is formed in a straight line, also two points in which a distance from this straight-line edge is substantially equal to a given folding width are connected by a convex pull-out groove in a direction of the straight-line edge, an edge of paper is pinched between a base of the paper folding auxiliary tool and an upper face of a tongue-like part enclosed by the convex pull-out groove, the edge of the paper is applied to both ends of the convex pull-out groove, also a part in which the paper protrudes from the straight-line edge of the paper folding auxiliary tool is turned back by 180 degrees along the straight-line edge of the paper folding auxiliary tool, and the paper is folded up with a given folding width. <P>COPYRIGHT: (C)2013,JPO&INPIT |
