サーボ型受振器。[Claims for Utility Model Registration] A pendulum that vibrates due to the action of gravity, a displacement detector that detects the amount of displacement of this pendulum, a differentiation circuit that differentiates the displacement output, and that generates a restoring force for the pendulum. A drive unit;
A voltage conversion means converts the differential output supplied through the drive unit into a voltage, and the speed output of the displacement is detected from the output end of the displacement detector, and the voltage is converted at the same time as this speed detection. A servo type geophone, characterized in that an acceleration output corresponding to the displacement is detected by a means.
