Claims

[Scope of utility model registration request]

In order to properly guide the magnetic tape along the recording or playback head disposed on the head base, the tape is held between a capstan and a pinch roller pressed against the capstan. A recording/playback device that runs a tape by the rotation of a stun and the rotation of a hinch roller that rotates in conjunction with the stun, in which the pinch roller and the roller bracket, which is rotatably supported by hand, are attached to a head base or this head base. is mounted on a roller arm disposed on a chassis in which the pinch roller is assembled so as to be rotatable in a direction that allows adjustment of the parallelism of the axis of the capstan and the axis of rotation of the pinch roller with respect to the tape running direction. Further, the magnetic tape recording/playback device is provided with an adjustment screw extending between the roller arm and the roller bracket so that the amount of rotation of the roller bracket relative to the roller arm can be adjusted by adjusting the screwing amount of the adjustment screw.
