Claims

[Scope of utility model registration request]

The driving torque is determined by inserting a torsion shaft between a driving machine and a driven device and detecting the torsional angular displacement of both ends of the torsion shaft through a torsion tube whose one end is coaxially fixed to the torsion shaft. A pair of parallel optical discs each having the same number of notches or holes arranged in equal pits along the circumference, each fixed to the torsion shaft and the torsion tube, and facing each other in close proximity; A light projector that projects a high-frequency optical pulse train signal onto a pair of parallel optical disks, and a light receiver that is provided opposite to the projector and receives the light pulse train signal that has passed through a notch or a through hole in the pair of parallel optical disks. 1. A torque measuring device comprising: a torque measuring device; and a torque calculation circuit that calculates torque by counting the number of pulses from the received light pulse signal of the light receiver.
