Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disc playback device, and more particularly to a vehicle-mounted disc playback device that can take two positions: horizontal and vertical.

[Conventional technology]

Generally, a CD disc playback device mounted on a vehicle is placed horizontally or vertically in the trunk of a vehicle. This CD disc playback device has a playback mechanism floatingly supported within the outer casing via a support frame to cope with vehicle vibrations. The support frame is suspended from the outer casing by a damper containing silicone rubber, and the side surface of the support frame is suspended by a vibration isolation spring.

That is, as shown in FIGS. 5(a) and 5(b), the CD disc playback device 50 has an outer casing 51, and within the outer casing 51, a support frame 52 is provided with a vibration-proofing spring provided in the center thereof. 53, and supports a reproducing mechanism for positioning and rotating a CD disc on the support frame 52 to reproduce information. When the disc playback device is placed horizontally, that is, placed horizontally, the lower end of the vibration isolation spring 53 is attached to the support point S of the support frame 52, and the upper end is attached to the support point S formed on the support plate 54 of the outer casing 51. attached to s1 (
Figure 5(a)). When the disc playback device is placed vertically, as shown in FIG. 5(b), the lower end of the anti-vibration spring 53 remains as it is, and only the upper end of the support plate 54 is rotated 90 degrees from the support point S1 to the support point S2. Transfer to.

Further, as a method of suspending the vibration isolating spring 53, as shown in FIG. 6, there is a method in which both ends of the vibration isolating spring 53 are hung differently depending on whether the vibration isolating spring 53 is placed vertically or horizontally. That is, in the case of horizontal installation, as shown in FIG. 6(a), the lower ends of the anti-vibration LO10 springs 53 are attached to the support points S and S on both sides of the support frame 52, and their upper ends are attached to the support points S of the outer casing 51. , S.

When changing from this state to vertical installation, both anti-vibration springs 53
are removed from their support points 5s10' 11 , and the distance between the support points S 1 and s of the support frame 52 and the support points S 1 and S of the outer casing 51 is changed as shown in FIG. 6(b).

[Problem to be solved by the invention]

However, in the method shown in FIG. 5 where one end of one vibration isolating spring is changed, the support frame 5
2 becomes unstable in a vertical state, sometimes taking an oblique position, and is unable to sufficiently absorb vibrations applied to the support frame 52.

Further, in the method shown in FIG. 6(b), the vibration isolating spring is completely removed when changing the posture, so the vibration isolating spring is easily lost, and the work of rehanging and replacing the vibration isolating spring is also complicated.

In view of these points, the present invention makes it easy to operate the spring when changing the posture of the disc playback device, and there is no need to remove either end of the vibration isolation spring, so there is no need to worry about losing it. The purpose is to provide a disc playback device that does not require a disc playback device.

[Means to solve the problem]

Therefore, the present invention provides a disc playback system in which a playback mechanism for positioning the disc at a predetermined position, reading it, and reproducing the information on the disc by RAD is housed in a support frame, and this support frame is floatingly supported on the outer casing. In the apparatus, at least one anti-vibration spring is provided between both sides of the support frame and both sides of the outer casing opposing thereto, and when the disc playback apparatus is horizontally arranged, the anti-vibration spring is attached to the support frame side. The end portion is rotatably supported on a horizontal plane passing through the center of gravity of a floating support frame including a regeneration mechanism, and the end portion of the vibration isolation spring on the outer casing side is attached to a support point on the outer casing side. The support point is configured to be able to rotate by a predetermined angle in an arc shape on the outer casing.

[Effect]

There should be at least one surface between the side surface and the opposite side surface of the casing, so that the device of the support frame supporting the regeneration mechanism is not vertically or vertically when placed horizontally or vertically.
One end of the vibration isolating spring is rotatably attached to a side of the casing on a plane passing through the center of gravity of the support frame when the device is horizontal, and the other end of the vibration isolating spring is attached to the outside. The support point on the outer casing side should be installed above the support point on the support frame side when the device is placed horizontally, and the support point on the outer casing side should be installed above the support point on the support frame side when the device is placed horizontally. Rotate the outer casing approximately 90 degrees in an arc to position it approximately above the support point on the support frame side.

This eliminates the need to take the trouble to remove the anti-vibration spring when changing the posture of the device, making work easier.Furthermore, when the device is placed vertically, the support frame is supported without tilting to the left or right, which absorbs vibrations. The effect is great.
