The front automatic storage system includes a plurality of shelves, a transferring apparatus, and a moveable frame. The shelves are arranged facing a semiconductor processing apparatus and at least one of the shelves is positioned above a transfer port of the semiconductor processing apparatus. The transferring apparatus is contrived to move among the shelves and transfer cassettes C between any shelf and the transfer port. The frame is contrived such that it can move the transferring apparatus and the at least one shelf positioned above the transfer port. The frame is also contrived such that it can move in a first horizontal direction toward and away from a first position where the at least one shelf is arranged above the transfer section.
