<p>In a device for positioning a magnetic tape on a sensing head (26) by means of guide pegs (16, 18) and/or guide rollers (12, 14), at least one elongated lever (22, 24) is provided which is rotatably guided at one end in a bearing (28, 30) and has a guide roller (12, 14) and an adjacent guide pin (16, 15) for the magnetic tape at the other end. The guide roller and the guide pin grip the magnetic tape in its rest position (20), and when the lever is rotated about the bearing first the guide roller alone and then the guide pin pulls the magnetic tape into the operating position, in which the magnetic tape is partially wound around the sending head. Positioning of the lever in its operating position is then effected by a centralising limit stop (48, 100).</p> |
