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. In another construction, a damper spring is mounted between a side panel of the main reproducing unit and a projection of each spring loaded arm rotatably mounted to the outer casing. The spring loaded arm rotates 90 degrees when is actuated by a shift lever pressed with each shift pin of a vertical mounting bracket, thus resetting its damper spring for corresponding to the horizontal or vertical position of the main reproducing unit.

In a further construction, a connecting rod arranged extending at one end outward from the outer casing is used to rotate the spring loaded arm through 90 degrees upon coming into direct contact with e.g. the floor of a vehicle.
