出点の通過時刻を異なる位置に配置した一対の検
出器で検出し、該通過時刻の時間差信号により前
記回転体の回転速度を検出する回転速度検出器に
おいて、前記一対の検出器の少なくとも一方の前
記回転体の回転中心からの距離を調整可能とした
ことを特徴とする回転速度検出器。 A rotational speed detection method that detects the passing time of a detection point provided on a rotating body to detect the rotational speed using a pair of detectors placed at different positions, and detects the rotational speed of the rotating body based on a time difference signal between the passing times. A rotational speed detector, characterized in that the distance of at least one of the pair of detectors from the center of rotation of the rotating body is adjustable.
