A miniature tape cassette comprises an integral one-piece drawn sheet metal casing having an upper wall, a lower wall and side walls, one side of the casing being opened. Aligned holes are provided in the upper and lower walls of the casing rotatably to receive hub portions of tape spools on which a magnetic tape is wound. The upper wall is provided with integral spring strips which extend from the holes toward a central portion of the open side of the casing. These spring strips flex outwardly to permit the insertion of the tape spools into the casing and then spring back into the plane of the upper wall so as to retain the tape spools in place. Guide rollers adjacent opposite ends of the casing and near the open side have axle portions that are received in slots provided in the upper and lower walls of the casing. Pads for pressing against the tape are provided at opposite ends of a leaf spring which is positioned in the casing by means of a pin having end portions received in the upper and lower wall. Small tab portions of the upper and lower walls at the open side of the casing are bent at right angles to provide guide elements for the tape. |
