<p>It is an object of the invention to provide a technique for taking out folded sheets without increasing the height of a stack of sheets in a stacking direction. A representative stack of sheets includes first sheet bodies 12A, 12B each formed by folding a sheet and having a fold 12Aa, 12Ba and an opening 12ab, 12Bb and second sheet bodies 13A each formed by folding a sheet and then further folding the sheet in the same direction. The second sheet body 13A includes a fold 13Aa and an opening 13Ab formed by the first folding and a gap 13c formed by the second folding. The fold and the opening of each of the first sheet bodies 12A, 12B are inserted into a region on the other side in the gap 13 in one of two second sheet bodies 13 such that the gaps 13 are open in the opposite directions with respect to each other and into a region on one side in the gap 13 in the stacking direction in the other second sheet body, respectively.</p> |
