However, in such a packing apparatus, since the size of the cardboard is substantially the same as the size of the entire recording paper stored therein,
It is difficult to hold the stacked recording sheets in a cardboard while holding them, and it is not easy to pack the recording sheets. Further, when the upper flap of the corrugated cardboard is folded to close the corrugated cardboard, there is also an inconvenience that the area near the fold on the upper part of the recording paper is folded so as to be caught in the base area of the upper flap. In other words, the area near the fold of the recording paper has a lower degree of adhesion between the sheets than the area at the center, and when a large number of recording sheets are stacked in a zigzag manner, the influence of the low degree of adhesion increases, and The upper portion of the formed recording sheet is curved so that the vicinity of the fold is higher than the central portion. Therefore, even if the central portion of the recording paper is just high enough to fit within the depth of the corrugated cardboard, the vicinity of the fold is higher than the upper flap fold position of the corrugated cardboard, and the area near the fold above the recording paper is folded by the upper flap. Caught in its base area,
It will be bent. Such partial bending of the recording paper significantly reduces product value,
