Claims

[Claims for Utility Model Registration] A rotating plate is provided with a rotation transmitting means for transmitting the rotation of the capstan to the rewinding reel stand, and when the magnetic tape is rewound and erased, the rotating plate rotates in the direction of rotation of the capstan. By rotating the tape, the rotation of the campus is transmitted to the rewinding rule table via a rotation transmission means provided on the rotating plate, and a recording/playback head and an erasing head for recording/playback are provided. In a head moving device for a magnetic recording/reproducing device in which a forward/backward plate is driven to an advanced position by a forward/backward plate drive means, the recording/playback head is movable in a direction in which the recording/playback head comes into contact with the magnetic tape and in a direction in which it separates from the magnetic tape. provided on the head support member supported by the advance/retreat plate,
This head support member is biased so that the recording/reproducing head moves in the direction in which it comes into contact with the magnetic tape, while
During rewinding and erasing operations, the movement of the head support member in the direction of the magnetic tape is restricted in response to the rotation of the rotating plate in the direction of rotation of the capstan so that the recording/reproducing head does not come into contact with the magnetic tape. 1. A head moving device for a magnetic recording/reproducing device, comprising a head support member regulating means.
