Claims

[Scope of utility model registration request]

A control member that is rotationally displaced according to the running direction of the magnetic tape, a head mounting plate to which a magnetic head is attached and one end of which is in contact with the control member, and a head mounting plate that is sealed to the control member. a spring member that urges the head mounting plate to maintain the abutment state, and a height position of one end side of the head mounting plate is changed by rotational displacement of the control member, and the magnetic tape is In the azimuth adjustment device for a magnetic head configured to adjust the azimuth of the magnetic head according to the running direction of the magnetic head, a fulcrum is provided by extending the other end side of the head mounting plate in the width direction of the head mounting plate. The head mounting plate is supported at the fulcrum part and is rotatable about the fulcrum part, and the spring member is made of a leaf spring, and the end of the leaf spring supports the head mounting plate in its width direction. An azimuth adjustment device for a magnetic head, characterized in that S is pressed parallel to the fulcrum portion over the entire area.
