ABSTRACT:
In a cassette type tape recorder, a bush rigidly mounted on a wall of a housing of the recorder around an opening in said wall from which a capstan for propelling the tape cantilevers, the capstan being received in a bore of said bush and protruding from the top of said bush by a length identical with the width of the tape, said bush having a base and a cylindrical body forming a step with the base having an outer diameter slightly less than the diameter of a cassette opening, and an upper tapered portion, said bush body entering said cassette opening and centering the latter by said tapered portion and supporting same by the stepped base, whereby the capstan rotation is guided by the bush and the camber effect on the protruding length is so reduced as to minimize the wow and flutter values of the tape recorder.
