Abstract
Magnetic head adjustment means for a magnetic tape machine, comprising a magnetic head mounting plate on which a magnetic head is securely mounted, said magnetic head mounting plate being pivotally movable about contact means to slidably extend through a base plate and engage said magnetic head mounting plate in a plane in which a head gap is contained. Depression means is provided to depress said contact means whereby said magnetic head is adjusted in its vertical position. Vertical position adjusting screw means adjusts the depression of said depression means. Inclination adjusting means is also provided to engage and pivotally move said magnetic head mounting plate whereby said magnetic head is adjusted in its inclination in a magnetic tape running plane.

Magnetic head adjustment means for a magnetic tape machine, comprising a base plate a magnetic head mounting plate on which a magnetic head is securely mounted adjacent to one end thereof;
- support means provided adjacent to a middle portion of said magnetic head mounting plate to movably attach said magnetic head mounting plate to said base plate to permit a head gap of said magnetic head to incline in a magnetic tape running plane and so as to resiliently urge said magnetic head mounting plate toward said base plate;
- contact means to slidably extend through said base plate and to engage said magnetic head mounting plate as a fulcrum in the plane in which the head gap is contained and at two points of said magnetic head mounting plate spaced to each other along the direction perpendicular to said tape running plate so that the gap containing surface of said magnetic head is maintained parallel to said tape running plane whereby said magnetic head mounting plate is maintained substantially parallel to the direction perpendicular to said tape running plane as said magnetic head mounting plate pivotally moves about said fulcrum;
- depression means disposed on the other side of said base plate to depress said contact means against the urging force of said support means whereby said magnetic head is adjusted in a vertical manner while said magnetic head is maintained parallel to said base plate in the direction perpendicular to the tape running plane;
- vertical position adjusting screw means threadedly extending through said depression means to adjust the depression of said depression means whereby said magnetic head is properly positioned in its vertical position;
- and inclination adjusting screw means threadedly extending through said base plate to engage said magnetic head mounting plate at the other end and to pivotally move said magnetic head mounting plate about said fulcrum against the urging force of said support means whereby said magnetic head is properly positioned in its inclination in said magnetic tape running plane.
