ト式テープレコーダのヘツド支持機構。[Claims for Utility Model Registration] (1) The magnetic head is installed in a head support mechanism of a cassette-type tape recorder that performs playback or switching recording tracks by reversing the magnetic head 180 degrees as the running direction of the tape changes. A tapered surface is formed on at least one of the rotating member or the bearing member that rotatably supports the rotating member, and the tapered surface is brought into contact with the mating member by a reaction force from the magnetic tape side acting on the magnetic head. A head support mechanism for a cassette tape recorder characterized by the following. (2) Utility model registration claim 1, characterized in that both the rotating member and the bearing member are provided with tapered surfaces that come into contact with each other due to the reaction force from the magnetic tape side acting on the magnetic head. Head support mechanism of the described cassette tape recorder.
