摘要： A platen knob includes a first hollow cylinder having one bottom wall, a second hollow cylinder extending from the interior surface of the bottom wall coaxially with the first cylinder. The second cylinder is fitted on a shaft of a cylindrical platen through a hollow boss of a casing housing the platen. A cavity defined between the sidewalls of the cylinders receives a vibration-proof lining and/or an acoustical layer. The lining suppresses a vibration of the platen knob. The acoustical layer seals the boss of the casing and leaks no noise from the interior of an electronic apparatus including a platen.
