目標座標における被検者の輪郭の最高点のＺ座標の値が、高さリミットを越える場合には（Ｓ１２：ＹＥＳ）、被検者の輪郭の最高点が高さリミットを越えた分だけＺ軸の目標座標値が減じられる（Ｓ１３）。目標座標における被検者の輪郭の最高点のＺ座標の値が、高さリミットを越えない場合には（Ｓ１２：ＮＯ）、上面板の現在の座標からＳ１１で読み込んだ目標座標までの上面板の動作を１００等分され、１刻みずつ進めたときの被検者の輪郭の軌跡が計算される（Ｓ１４）。Ｓ１４の処理で求めた全軌跡における被検者の輪郭の最高到達点が高さリミットを越えない場合には（Ｓ１６：ＮＯ）、目標座標に向けて上面板の動作を実行する（Ｓ１７）。 In the present invention, when the z coordinate value of the highest point of the contour of a subject with reference to a target coordinate exceeds a height limit (S12: YES), the excess of the highest point of the contour of the subject over the height limit is subtracted from the z coordinate value of the target coordinate (S13). When the z coordinate value of the highest point of the contour of the subject with reference to the target coordinate is not higher than the height limit (S12: NO), movement of an upper plate from the current coordinate of the upper plate to the target coordinate, which has been read in S11, is equally divided into 100 movements and the trajectory of the contour of the subject is calculated for each movement (S14). When the highest point of the entire contour determined by the process of S14 is not higher than the height limit (S16: NO), the movement of the upper plate to the target coordinate is executed (S17).
