摘要:
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.
