A pair of anti-vibration springs 11 are provided on one side of the apparatus 1 between the side surface 3a of the support frame 3 and the side surface 2a of the outer casing 2. The side surfaces 2a and 3a are surfaces that do not have a top-to-bottom relationship when the device 1 is placed horizontally or vertically. These vibration-proof springs 11 absorb the vibration of the support frame 3 when the vehicle vibrates in cooperation with the damper 4. The lower end of the anti-vibration spring 11 is rotatably mounted on a support shaft 10 fixed to the side surface 3a of the support frame 3, and the upper end of the anti-vibration spring 11 is rotatably mounted on the side surface 2a of the outer casing. The rotating plate 12 is fixed to the protruding end 12 a of the rotating plate 12. As shown in FIGS. 1 and 2, the rotating plate 12 is pivotally attached to the side surface 2a of the outer casing 2 by a supporting shaft 13, and the rotating plate 12 is point-symmetric with respect to the supporting shaft 13. Arc-shaped openings 14 and 15 are provided.
These arc-shaped openings 14 and 15 are formed over an angle range of 90 degrees around the support shaft 13, and the arc-shaped openings 14 and 15 have guide shafts 16 and 15 fixed to the side surface 2 a of the outer casing. 17 are engaged with each other. Note that springs 18, 18 are provided between the rotating plate 12 and the side surface 2a of the outer casing 2, and the rotating spring 12 stops the rotating plate 12 at a predetermined position.

As shown in FIG. 5, the support shaft 10 attached to the side surface 3a of the support frame 3 intersects a horizontal plane HP passing through the center of gravity G of the support frame 3 including the magazine M and the reproducing device and the side surface 3a. When the disc reproducing apparatus 1 is placed horizontally, the protruding end portion 12a of the rotating plate 12 on which the vibration isolating spring 11 is mounted is perpendicular to the support shaft 10 when the disc reproducing apparatus 1 is viewed from the side. It is located above.

In order to replace the horizontal state, that is, the horizontal state, with the vertical state, that is, the vertical state as shown in FIG. 6, a rotary rod is inserted into the space 31 of the support shaft 13 of the rotary plate 12, and It is rotated 90 degrees in the same direction (counterclockwise in the figure) so that the protruding end 12a of the rotation plate 12 and the support shaft 10 are aligned with the vertical plane VP passing through the center of gravity G. The vertical plane VP when the device 1 is placed vertically corresponds to the horizontal plane HP when the device 1 is placed horizontally. If the support points at the upper and lower ends of the vibration-proof spring 11 are made to coincide with the vertical plane VP in this manner, the support frame 3 can be accurately held in the vertical position, and even if the device 1 vibrates, Vibration of the support frame 3 can be effectively prevented. If the two rotating plates 12 are connected by a link L, the other rotating plate 12 can be rotated by the same angle only by rotating one of the rotating plates 12 by 90 degrees (FIGS. 5 and 6).

Confirmation openings 60 and 61 for confirming the position of the turning plate 12 are provided in the turning range of the turning plate 12 on the side surface 2a of the outer casing 2. An identification portion 62 is formed at an appropriate position of the rotating plate 12.
