Claims (1)

[Scope of utility model registration claims] (1) Recording and recording on a magnetic tape by running it closely on it.
In a rotating head assembly comprising a magnetic head consisting of a head chip that performs playback and a head base that holds it, and a rotating body that rotates while supporting this magnetic head, a head base support plate is provided, and a pin is connected to the head base support plate. The head base of the magnetic head is rotatably engaged to form a magnetic head assembly, and the head base support plate has a through hole, and by passing a mounting screw through the through hole, the magnetic head assembly can support the head base. The head base is fastened to the rotating body by a plate, so that the head base is rotatably attached to the rotating body around the pin, and the head base is attached to one of the opposing positions with the pin in between. a height adjustment bolt having a threaded hole on the side and screwed into the threaded hole of the head base through a through hole provided in the rotating body; The head base support plate is provided with a height adjustment screw that abuts on the side opposite to the position of the screw hole, and by adjusting these height adjustment screws and height adjustment bolts, the direction and amount of deflection of the head base support plate can be adjusted. The height of the head gear located at the tip of the head tip can be adjusted, and the head base can be rotated about the pin so that the posture of the tip of the head tip remains constant at any height adjustment position. A rotating head assembly characterized by: (2) The rotation according to claim 1 of the utility model registration claim, characterized in that the height adjustment screw and the height adjustment bolt, which are opposite to each other with the pin in between, are arranged as close as possible. Head assembly. (3) The rotating head assembly according to claim 1, wherein a space is provided in a portion where the rotating body, the head base, and the head base support plate adjacent to the head base face each other. (4) Utility model registration claim 1, characterized in that the space is provided by inserting a spacer having a constant thickness and a shape that does not overlap the head base between the head base support plate and the rotating body. The rotary head assembly according to item 3. (5) A utility model registration characterized in that the space is provided by providing a step between the head base and the part adjacent to the head base supporting plate and the vicinity of the through hole of the head base supporting plate. A rotary head assembly according to claim 3. (6) Claims for registration of a utility model characterized in that the space is provided by providing relief grooves on the rotating body side of the head base and a portion adjacent to the head base that faces the head base support plate. The rotating head assembly according to paragraph 3. (7) Utility model registration claim 1, characterized in that a groove is formed on the surface of the head base support plate between the through hole and the pin, substantially perpendicular to the direction in which the head base support plate bends and deforms. Rotating head assembly as described in section. (8) The lower surface of the head of the height adjustment bolt and the axis of the threaded portion of the height adjustment bolt are perpendicular, and the screw hole of the head base and the fixing surface of the head tip are perpendicular, and the rotation 2. The rotating head assembly according to claim 1, wherein a surface of the head of the height adjusting bolt that contacts the lower surface of the head of the height adjusting bolt is parallel to a rotating surface of the head tip.
