An interior of the package box is partitioned by an intermediate partition plate into a first accommodation portion and a second accommodation portion. A small partition plate is folded into the package box to form a third accommodation portion. An instruction manual and a device body are accommodated in the first accommodation portion and the second accommodation portion, and a small article and the like are accommodated in the third accommodation portion. The small partition plate is prevented from unfolding open by an edge side of the first connection piece. Therefore, the small article and the like accommodated in the third accommodation portion do not move into the first accommodation portion. The third accommodation portion can be formed by a simple operation (inserting operation is unnecessary) only by folding the small partition plate into the package box.
