Claims

[Scope of utility model registration request]

A magnetic head that is switched and rotated according to the reversal of tape running;
A slide plate for operating an operating arm that rotates this magnetic head, a partially toothed gear provided with a drive member that reciprocates this slide plate, and a partially toothed gear for imparting initial rotation to the partially toothed gear to mesh with the drive gear. a trigger member, a head substrate that supports the rotating magnetic head and the operating arm and moves forward and backward; and when the head substrate is in the forward position, a part of the substrate triggers the t-IJ member. A head rotation device for a reversible running cassette tape recorder, comprising a trigger regulating means for inhibiting a trigger.
