Abstract: A vibration damping support mechanism for a recored data reproducing apparatus is provided which allows the apparatus to be installed in either a horizontal or vertical position without shifting the tensioning direction of damper springs. Each pair of the damping springs is mounted between a main reproducing unit and an outer casing. The two damper springs are arranged to extend in the thicknesswise and depthwise directions of the main reproducing unit respectively or arranged tilting at a predetermined angle. In the horizontal position, external vibrations are absorbed by the elastic action of one of the two damper springs and thus prevented from propagating directly to the main reproducing unit. Similarly in the vertical position, such external vibrations are absorbed by the elastic action of the other damper spring and prevented from propagating directly to the same.

Abstract: A knob device mounted on an operating member such as an on/off switch or volume control of a piece of audio or video equipment has a push button which is pushed from the front side of a panel. The push button has a flange which is received in an escutcheon having an inner flange at its front end. A sheet having small projections on at least one of its inner and outer peripheries is disposed between the inner flange and the flange of the push button, as well as between the push button and the escutcheon, thereby to prevent any play or backlash from occurring. The sheet may be thin and interposed between the flange of the push button and the inner surface of the escutcheon in sliding contact with the flange. The knob device may be made of a light transmitting resin mounted on the operating element. The knob has a flange and a mark on its face formed by a non-light transmitting panel. The panel has a non-light transmitting knob guide formed on its rear to guide the flange.
