ほぼ等間隔に饅けられた穴（または突起）を使用し、回
転体の該穴（または突起）が近傍を通過したことを検出
して電気信号に変換する装置と、該電気信号から回転体
の回転周期番演算し回転速度を算出する装置とからなる
回転加減速検出装置において、複数個の穴（または突起
）のうち、−個の穴（または突起）から、つぎの−個の
穴（または突起）が通過するまでの周期をその都度演算
し、該周期変動から回転体が一回転しないうちに原動機
の急加減速を検出するように構成したことを特徴とする
回転加減速検出装置。It uses holes (or protrusions) placed at approximately equal intervals on the concentric circle of the rotating surface of a rotating body that rotates in synchronization with the prime mover, and detects when the holes (or protrusions) of the rotating body have passed nearby. In a rotational acceleration/deceleration detection device consisting of a device that converts the signal into an electrical signal, and a device that calculates the rotational speed of a rotating body by calculating the rotation period number of the rotating body from the electrical signal, one of the holes (or protrusions) - The cycle from one hole (or protrusion) to the next - number of holes (or protrusions) is calculated each time, and sudden acceleration or deceleration of the prime mover is detected from the period fluctuation before the rotor has made one revolution. A rotational acceleration/deceleration detection device characterized in that it is configured to.
