回転計。 A guide roller that detects rotation, a bobbin for winding a secondary coil (or primary coil), one of which surrounds the outer periphery of the iron core, and which integrates the number of rotations as the guide roller rotates, and the secondary coil (
or a primary coil) unwinding bobbin, means for passing current through the primary coil (or secondary coil) wound around the iron core, and a winding bobbin wound around the primary coil and the bobbin surrounding the outer periphery of the iron core. An integrating tachometer comprising: detecting means for detecting an electromotive force induced in a secondary coil wound around a bobbin surrounding the outer periphery of the iron core due to mutual induction with the secondary coil.
