    • A recording and/or reproducing apparatus which employs a disc as a recording medium and in which a recording and/or reproducing unit is supported in a floating state via plural damper units and elastic members. The recording and/or reproducing apparatus includes a recording and/or reproducing unit mounted on a base member via plural damper units and a closure member rotatably mounted on the base member for covering the recording and/or reproducing unit. Between the closure member and the recording and/or reproducing unit, there is mounted a spring plate for biasing the recording and/or reproducing unit towards the base member. When the closure member is at a position of sheathing said recording and/or reproducing unit, the recording and/or reproducing unit is maintained at a position in which the weight of the recording and/or reproducing unit, the elastic force of the damper units and the elastic force of the springplate counterbalance one another. The damper unit supporting the recording and/or reproducing unit on the base member has a vibration absorbing member and a further elastic member fitted on the outer side of the vibration absorbing member. There is also provided a supporting member on which is arranged the recording and/or reproducing unit. A further elastic member constituting the damper unit is provided between the base member and the supporting member for biasing the recording and/or reproducing unit toward the closure member against the bias of a spring plate.
    • 一种记录和/或再现装置,其使用盘作为记录介质,并且其中记录和/或再现单元经由多个阻尼器单元和弹性构件以浮动状态支撑。 记录和/或再现装置包括经由多个阻尼器单元安装在基座构件上的记录和/或再现单元和可旋转地安装在基座构件上用于覆盖记录和/或再现单元的闭合构件。 在封闭构件和记录和/或再现单元之间,安装有用于朝着基座构件偏压记录和/或再现单元的弹簧板。 当封闭构件处于所述记录和/或再现单元的护套位置时,记录和/或再现单元保持在记录和/或再现单元的重量的位置,阻尼器单元的弹力 并且弹性板的弹性力相互抵消。 支撑在基座上的记录和/或再现单元的阻尼器单元具有安装在吸振件外侧的振动吸收件和另一弹性件。 还设置有支撑构件,在该支撑构件上布置有记录和/或再现单元。 构成阻尼器单元的另一个弹性构件设置在基座构件和支撑构件之间,用于克服弹簧板的偏压将记录和/或再现单元朝向闭合构件偏压。
