Abstract
The unfolding device includes a frame that provides a space for placing an empty box, a plurality of stress concentrating members that unfolds a plurality of corners of the empty box, a plurality of movable portions, and a power transmission portion that transmits power for moving the stress concentrating member via the movable portion. The stress concentrating member is brought into contact with the inside of the empty box from the opening side of the empty box, thereby placing the empty box. The power transmission portion transmits, to the stress concentrating member, power for moving the stress concentrating member so as to bring the stress concentrating member into contact with the corner. The power transmission portion transmits the power to the stress concentrating member so that the stress concentrating member unfolds the corner by tearing and opening the corner.
