Problem to be solved: to provide a male and female identification device of a spermatozoa capable of discriminating the male bites accurately and accurately at a low cost.Solution: in this apparatus, the tip end of the hollow rod member 6, which is coupled to the hollow rotary shaft of the electric motor 7 mounted on the arm part 4a of the support device 4, is rotated and held by the adsorption mechanism 5 of the tip of the hollow rod member 6 to rotate and hold the egg 10 at a predetermined height from the floor surface, and the beam profiler 3 is its In the vertical measurement range above the average long diameter, a laser beam is irradiated onto the surface of the egg 10 to obtain a line shaped reflection beam to measure the entire circumference including both ends of the egg 10.The personal computer 12 discriminates the male and female shape of the three-dimensional shape of the reflected beam of the reflected beam of the vertical direction of the beam 10 by the beam profiler 3 as an outline image which can be displayed on the display portion.Diagram【課題】簡易に精度良く短時間で形状計測を行うことができ、低コストで適確に雄雌識別できる有精卵の雌雄識別装置を提供する。【解決手段】この装置では、支持装置4のアーム部4aに取付けられた電動機7の中空な回転軸に結合されて回転する中空棒部材6の先端の吸着機構5で有精卵10の鈍端を吸着保持して床面から所定の高さで卵10を回転させ、ビームプロファイラ3がその平均的な長径寸法を超える鉛直方向の測定範囲で卵10の表面へレーザを照射してライン状の反射ビームを取得して卵10の両方の端を含む全周断面の計測を行う。パーソナルコンピュータ12は、ビームプロファイラ3による鉛直方向での反射ビームの卵10の全周断面に係る計測結果を画像処理した3次元形状を表示部へ表示可能な輪郭画像として雌雄判定する。【選択図】図1
