Claims

[Claims for Utility Model Registration] 1. A magnetic head is attached to the head mounting plate via a head azimuth adjustment mechanism, and an inner tape guide near the magnetic head and an outer tape away from the magnetic head are installed on both sides of the magnetic head. In the head peripheral mechanism for a cassette-type tape recorder, each of the pair of tape guides is fixed to the head mounting plate, and the pair of inner tape guides are connected to the head through the recording/playback head inlet of the tape cassette. It can be introduced into the tape cassette together with the magnetic head, and has an inclined surface in contact with the edge of the tape on one of the upper and lower tape widthwise movement regulating protrusions, and the tape widthwise movement regulating protrusion without the inclined surface has an inclined surface that contacts the edge of the tape. 1. A head peripheral mechanism for a cassette-type tape recorder, characterized in that a height position of a regulating surface of the tape guide and a regulating surface of the tape width direction movement regulating protrusion of the pair of outer tape guides are made to match. 2. A cassette type in which a magnetic head is attached to a head mounting plate via a head azimuth adjustment mechanism, and an inner tape guide close to the magnetic head and an outer tape guide distant from the magnetic head are provided on both sides of the magnetic head. In the head peripheral mechanism for a tape recorder, each pair of outer tape guides is integrally formed and fixed to the head mounting plate, and the pair of inner tape guides are directly fixed to both sides of the magnetic head to adjust the upper and lower tape width. One of the directional movement regulating protrusions has an inclined surface in contact with the tape edge, and the regulating surface of the tape widthwise movement regulating protrusion without this inclined surface and the tape widthwise movement regulating of the pair of outer tape guides. A head peripheral mechanism for a cassette type tape recorder, characterized in that the height position of the protrusion matches the regulating surface.
