Claims

[Scope of utility model registration request]

Load it into a video tape recorder or tape recorder,
In a torque measurement cassette that measures the dynamic torque or static torque of a tape drive reel shaft, a measurement gauge built into the cassette body is mounted on two wheels: an inner ring into which the reel shaft is fitted, and an outer ring around which the tape is wound. The two wheels are connected rotatably to each other, the two wheels are connected by a spiral spring, and a polarizing plate is fixed to each of the inner and outer rings, which are stacked one on top of the other. A cassette gauge for torque measurement characterized by having a reflector plate installed on the cassette.
