Claims

[Scope of utility model registration request]

A support shaft having a threaded portion at the tip is erected on the main board, and a head mounting plate holding an audio head is supported on this support shaft so as to be able to move up and down and freely rotate, and the head mounting plate is moved in the axial direction of the support shaft. In addition, an elastic member is provided that urges the head mounting plate simultaneously in the direction of rotation, and the axial movement of the head mounting plate is regulated by a height adjustment nut screwed into the threaded portion, so that the rotation of the head mounting plate is horizontally In a VTR audio head position fine adjustment device that is regulated by a position adjustment mechanism, the horizontal position adjustment mechanism has a stopper surface parallel to the support shaft on either the main board or the head mounting plate, and a rotating member on the other side. are provided, one end of the rotating member is brought into pressure contact with the stopper surface by the elastic force in the rotating direction of the elastic member, and the rotating member is locked in a fixed position by a horizontal adjustment screw so as to be freely rotationally adjustable. . A VTR audio head position fine adjustment device, characterized in that the head mounting plate can be rotated around the support shaft by rotation of the horizontal adjustment screw.
