ことを特徴とする振動検知装置。 A motor, a gearbox that transmits the rotation of the motor and has two gear mechanisms with different gear ratios, a stop detection rotating body that has a common rotation axis with a gear with a small number of teeth, and a rotation that shares a common rotation with a gear with a large number of teeth. A fine movement detection rotating body having a shaft, a stop detection circuit that determines that the rotation speed of the stop detection rotation body is less than a predetermined value as a stop, and a fine movement detection circuit that determines that the rotation speed of the fine movement detection rotation body is more than a predetermined value as a fine movement. A vibration detection device comprising: an AND circuit that takes an AND condition of a stop detection signal of a stop detection circuit and a slight movement detection signal of a slight movement detection circuit and outputs a vibration detection signal.
