One side of the quadrangular field the admission port (55) with the storage field which becomes (20) the run car of the self-propelled type which is stored (12) being, the storage field (20) position in 4 corners the run car (12) the admission port which shows in the relative coordinate which designates position as standard (55) point side, and, the tripartite of the second dot and inner part side, and storage point acquisition means and the run car which acquire the four-points (12) with the storage field (20) with you acquire the standard distance Ls which shows the distance betweenWhen the standard distance sensing station (35) with, the run car (12) the storage field (20) the occasion where it gets near, standard distance Ls is first amendment distance N1 or more, the run car (12) it controls movement on the basis of with point, and the second dot when standard distance Ls is under first amendment distance N1, the run car (12) the portable control section which controls movement (33) with it has at least on the basis of the tripartite, and the four-points.四角形の領域の一方が進入口(55)となる収容領域(20)に収容される自走式の走行車(12)であって、収容領域(20)の4隅の位置を走行車(12)の位置を基準とした相対座標で示す進入口(55)側の第一点、および、第二点と、奥側の第三点、および、第四点とを取得する収容ポイント取得手段と、走行車(12)と収容領域(20)との間の距離を示す基準距離Lsを取得する基準距離検出部(35)と、走行車(12)が収容領域(20)に近づく際に、基準距離Lsが第一補正距離N1以上の場合、第一点と第二点とに基づき走行車(12)の移動を制御し、基準距離Lsが第一補正距離N1未満の場合、少なくとも第三点、および、第四点に基づき走行車(12)の移動を制御する移動制御部(33)とを備える。
