Claims

[Scope of utility model registration request]

A vertical adjustment mechanism comprising a magnetic head mounting plate to which a magnetic head is attached and a rotatable driven member, and which moves a predetermined location of the magnetic head mounting plate in the height direction of the magnetic head by rotation of the driven member. a reciprocating member that moves the vertical adjustment mechanism together with the magnetic head mounting plate in a direction in which the magnetic head advances relative to the magnetic tape; and a drive member that rotates by a rotation operation, the reciprocating member The magnetic head on the magnetic head mounting plate is moved forward relative to the magnetic tape by reciprocating, and the driven member is engaged with the driving member, and the magnetic head is mounted by the driving member via the driven member. A magnetic head adjusting device characterized in that a predetermined portion of the plate is moved in the height direction.
