レコーダのトルク測定装置。The reel has a reel in which an inner ring that engages with the reel shaft of the cassette tape recorder and an outer ring around which the tape is wound are connected via a thinly wound spring, and the inner ring and outer ring are connected as the thinly wound spring deforms. A cassette-type torque gauge that can determine the rotational torque of the reel shaft from the rotational angle difference, a marker for detecting the rotational phase provided on the inner ring and rear wheel of the cassette-type torque gauge, and a rotational phase detection marker provided on each of the inner and rear wheels of the cassette-type torque gauge. a pair of sensors that are installed at the sensor and detect the passing of the corresponding markers, and an arithmetic circuit that measures the time difference between the passing timings of the markers detected by the pair of sensors and calculates the rotation angle difference based on the time difference. A torque measuring device for a cassette tape recorder, comprising:
