<p>The recorder uses a cassette (4) with at least one hole on its wide side, through which a driving pin for a reel is passed when the cassette is inserted, and at least one hold in one of its narrow sides, through which a magnetic head can be inserted by a feeding device controlled by two operating elements (9) against a spring pressure (10). The magnetic head is protected against mechanical strains produced if one tries to remove the cassette when the head is inserted. The operating element (9) releasing the feeding device is placed so that the cassette can be reached only after the operating element is moved out of the way.</p> |
