Claims

[Claims for Utility Model Registration] In a cassette casing that can be installed in a cassette mounting part of a cassette type tape recorder, (al) a winding-side rotating body disposed at a position corresponding to the winding-side reel axis of the tape recorder; (b) an engagement protrusion attached to the take-up side rotary body for engaging the take-up side rotary body with the take-up side reel shaft; (C) corresponding to the supply side reel shaft of the tape recorder; (d) a rotary ring disposed concentrically with and rotatably relative to the outer periphery of the support portion; (e) the tape recorder; a tape-like body configured to be transported by a tape-pulling force exerted by a capstan and a pinch roller, and associated with the winding-side rotating body and the rotating wheel, respectively; further comprising urging means for urging the rotating ring relative to the support portion in a direction opposite to the direction of the rotational torque applied to the rotational ring through the body, the support portion being urged at least in the rotation direction the coupling is substantially coupled to the cassette casing at the cassette casing, and the coupling is configured to be readjustable so that the coupling of the support to the cassette casing can be released, the support can be rotated an appropriate amount, and then coupled again. , a tape tensile force caused by a capstan and a pinch roller of a cassette tape recorder configured to measure a tape tensile force according to the rotational position of the rotary wheel rotating with respect to the support part against the urging means; measuring device.
