SOLUTION: A pack 1 is provided with a plurality of sets of hole parts 8 and 9 corresponding to the length of a set of positioning pins 5 and 6 and the thickness of the pack 1 itself on each of two surfaces being demarcated by a center line A. The hole parts 8 and 9 are aligned with the pins 5 and 6 along two lines that are in parallel with the edge part 9, and the hole parts 8 and 9 are arranged along each line and at an equal distance for the pins 5 and 6. Then, the pack 1 is piled up by inserting the positioning pins 5 and 6 into the hole parts 8 and 9 of one or two or more additional packs being arranged horizontally and by shifting them. |
