PROBLEM TO BE SOLVED: To provide a shape inspection device for inspecting a shape of a three-way frame more precisely than before.SOLUTION: A shape inspection device 100 for inspecting a shape of a three-way frame of an elevator entrance door system includes: a three-way frame 1 covering an opening part provided on an entrance of each floor of an elevator; and an entrance door provided in an opening part and capable of opening and closing along a doorsill 3 in linking with a car side door of the elevator, and further includes: angle measuring means 8A, 8B for measuring an angle of the inclination of a side face 101 of the three-way frame for the Z axis in a direction reverse to a gravity direction; the angle of the inclination of a top face 103 of the three-way frame for the Y axis, and the angle of the inclination of the doorsill for the Y axis; distance measuring means for measuring a distance up to the side face of the three-way frame from distance measuring means 6A and the distance up to the top face of the three-way frame from distance measuring means 6B; and a shape calculation part 10 for calculating a predetermined parameter value showing the shape of the three-way frame using a coordinate value on a YZ plane formed by the Y axis and the Z axis based on a signal showing the angle and the signal showing the distance. 【課題】従来に比べて正確に三方枠の形状を検査するための形状検査装置を提供する。【解決手段】エレベーターの各階の乗場に設けられた開口部を覆う三方枠１と、開口部に設けられ、エレベーターのかご側ドアと連動して敷居３に沿って開閉可能な乗場ドアとを備えたエレベーター乗場ドアシステムの三方枠の形状を検査する形状検査装置１００であって、重力方向と逆方向のＺ軸に対する三方枠の側面１０１の傾きの角度と、Ｙ軸に対する三方枠の上面１０３の傾きの角度と、Ｙ軸に対する敷居の傾きの角度とを計測する角度計測手段８Ａ、８Ｂと、距離計測手段６Ａから三方枠の側面までの距離と、距離計測手段６Ｂから三方枠の上面までの距離とを計測する距離計測手段と、角度を示す信号と距離を示す信号とに基づいて、Ｙ軸及びＺ軸により形成されるＹＺ平面上の座標値を用いて三方枠の形状を示す所定のパラメータの値を演算する形状演算部１０とを備えた。【選択図】図５
