により圧延材の板巾方向の振巾及び振動数を計測
することにより形状を得る形状検出器において、
投光系，受光系に多角形回転反射体を設けこれを
同期的に回転させることにより板巾方向の走査を
可能としたことを特徴とする形状検出器。 In a shape detector that obtains the shape by measuring the amplitude and frequency of the rolled material in the width direction by measuring the distance based on the optical path difference between a light source and a light receiver,
A shape detector characterized in that a polygonal rotating reflector is provided in the light emitting system and the light receiving system and is rotated synchronously to enable scanning in the board width direction.
