2. Description of the Related Art Generally, a CD disk reproducing apparatus mounted on a vehicle is placed horizontally or vertically in a trunk of a vehicle. In this CD disk reproducing apparatus, a reproducing mechanism is floated in an outer casing via a supporting frame to cope with vehicle vibration. The support frame is suspended from the outer casing by a damper containing silicon rubber, and the side surface of the support frame is suspended by a vibration-proof spring.

That is, as shown in FIGS. 10 (a) and 10 (b), the CD disk reproducing device 50 is provided with an outer casing 51.
And a support frame 52 in the outer casing 51.
Is supported by a vibration-proof spring 53 provided at the center thereof, and a support mechanism for positioning the CD disk and rotating it to reproduce information is supported by the support frame 52. When the disc reproducing apparatus is in a horizontal state, that is, in a horizontal position, the lower end of the vibration isolating spring 53 is attached to the support point So of the support frame 52, and the upper end is the support point formed on the support plate 54 of the outer casing 51. It is attached to S1 (FIG. 10 (a)). When the disk reproducing apparatus is set vertically, as shown in FIG. 10 (b), only the upper end is supported at the supporting point S1 while the lower end of the anti-vibration spring 53 is left as it is.
Is shifted to the support point S2 of the support plate 54 rotated 90 degrees from the position. This transfer operation was performed by opening a cover and the like provided on the outer casing 2.

[0004]

However, in the above-described system in which the vibration isolating spring is changed, the weight of the frame which is floatingly supported is applied to the vibration isolating spring, so that the anti-vibration spring resists a considerable load. In addition, the operation of moving the anti-vibration spring must be performed. In such a state, it is difficult to force the small vibration-proof spring itself or the member to which the vibration-proof spring is attached by directly holding it with a finger and to perform the work, and it is difficult to apply force and it is troublesome.

Further, after the cover is closed after the cover is replaced, the mounting position of the vibration-proof spring cannot be confirmed from the outside, and there is a possibility that the vibration-proof spring may be used in a suspended state which is not adapted to the use posture.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a device which can smoothly and easily change the vibration isolating spring.

After the magazine M is stored in the support frame 3 through the opening 5 on the front surface of the support frame,
The trays in the magazine M are kicked out one by one by a kicking device (not shown), and the kicked-out trays t are positioned at the positions shown in the figure. Rotated at rotational speed, compact disc d
The above information is read by a pickup.

The disc reproducing apparatus 1 can be placed horizontally as shown in FIG.
It is used in a vertical position by raising it 0 degrees vertically,
Normally, the desired disk d is stored together with the tray in the first trunk by operating the operation panel in the cab.
It is kicked out to the position as shown in the figure, and the information thereon is read by the pickup.

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 rotary plate 12 is pivotally attached to the side surface 2a of the outer casing 2 by a support shaft 13, and the rotary plate 12 is point-symmetric with respect to the support 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 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.

The support shaft 13 is fixed to the rotary plate 12 and is rotatably mounted on the side surface 2a of the outer casing. The support shaft 13 has a circular flange 30 on the side surface 2a. The support shaft 13 has a hexagonal space 31 at the center thereof as an engagement portion with an operation tool (not shown).
The rotating plate 12 is exposed to the outside, and the rotating plate 12 can be rotated by a predetermined angle (usually 90 degrees) by inserting a hexagonal rotating rod or the like as an operating tool into the space 31. In addition, as a mechanism for rotating the rotating plate 12 from outside the outer casing, a projection 3 functioning as a moving member together with the rotating plate 12 is used.
2, the protrusion 32 may be moved along an arc opening 33 as a restricting portion formed on the side surface 2a (FIG. 4).

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.
The identification portion 62 is colored red, blue, or the like, for example. When the identification portion 62 is aligned with the confirmation openings 60 and 61, the identification portion 62 is visually observed from the outside.

In the horizontal position shown in FIG.
2 is located at the position shown in FIG.
When the rotating plate 12 is rotated by 90 degrees when changing from the horizontal position to the vertical position, the identification portion 62 can be visually recognized through the confirmation opening 61. Therefore, the position of the rotating plate 12 can be confirmed by which of the confirmation openings allows the identification section 62 to be viewed.

As shown in FIG. 9, the discriminating portion is formed to be vertically long, the outer position P1 from the center of the rotating plate 12 is set to red, the inner position P2 is set to blue, and the red outer position P1 is set.
The confirmation opening 64 in the case of horizontal installation may correspond to the confirmation opening 65 in the case of the horizontal placement, and the confirmation opening 65 in the case of the vertical installation may correspond to the inside position P2 of blue, so that the color that can be recognized is changed according to each posture.

The mechanism for confirming the position of the rotating plate comprising the identification portions 62 and 63 of the rotating plate 12 and the corresponding confirmation openings 60, 61, 64 and 65 is, in particular, shown in FIG. In the embodiment shown in FIG. 4, the position of the rotary plate 12 can be confirmed by confirming the position of the projection 32 without any need.
