Claims

[Scope of utility model registration request]

When loading a tape in a magnetic recording/reproducing device that draws a tape out of a tape cassette and attaches it to a rotating cylinder to form a predetermined tape running path, a guide pin and a guide roller that pull out the tape and attach it to the rotating cylinder are used. a pair of guide roller bases, and a pair of guide grooves that guide the guide roller bases, and the guide roller bases extend over the guide grooves on the tape entry side with respect to the rotary cylinder, and when the guide roller bases are in a loading operation, the guide rollers a rotating arm that is in contact with the base and rotated so as not to interfere with the operation of the guide roller base; a shaft that is provided on the chassis as a rotation axis of the rotating arm and has a threaded tip; A tape guide having a flange, a full-width erasing head, and an impedance roller are provided on the rotating arm, and a compression torsion spring installed coaxially with the rotating axis of the rotating arm allows the rotating arm to be positioned at a predetermined position on a plane. The height of the rotating arm is changed by biasing the rotating arm in the height direction and moving the nut that prevents the rotating arm from coming off forward or backward. A tape guide adjustment mechanism characterized in that the tape guide height on a rotating arm is configured to be adjustable.
