  • Vibration damping suspension mechanism for recorded data reproducing apparatus
    Patent number: 5663943
    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.
    Type: Grant

    Date of Patent: September 2, 1997
    Assignee: Pioneer Electronic Corporation
