Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc reproducing apparatus, and more particularly to an on-vehicle disc reproducing apparatus which can take two postures, horizontal orientation and vertical orientation.

[Conventional technology]

In general, an on-board CD disc reproducing apparatus is placed in a trunk of a vehicle by being placed horizontally or vertically. In this CD disc reproducing apparatus, a reproducing mechanism is floatingly supported in the outer casing through 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 faces of the support frame are suspended by vibration-proof springs.

That is, as shown in FIGS. 5 (a) and 5 (b), the CD disc reproducing apparatus 50 has an outer casing 51, and a support frame 52 is provided in the outer casing 51, and a supporting frame 52 is provided in the central portion thereof. It is hung by 53 and CDs on the support frame 52.
A playback mechanism is supported for positioning and rotating the disc to play information. When the disk reproducing device is in a horizontal state, that is, when it is placed horizontally, the lower end of the vibration-proof spring 53 is attached to the support point S ₀ of the support frame 52, and the upper end thereof is a support formed on the support plate 54 of the outer casing 51. Point S ₁
(Fig. 5 (a)). When the disc reproducing apparatus is placed vertically, as shown in FIG. 5 (b), the lower end of the anti-vibration spring 53 remains unchanged and only the upper end thereof is supported by the supporting point S ₁
Is moved to the support point S ₂ of the support plate 54 rotated by 90 degrees.

Further, as a method of suspending the vibration-proof spring 53, there is also a method of suspending both ends of the vibration-proof spring 53 in the case of vertical installation and horizontal installation as shown in FIG. That is, in the case of horizontal placement, the sixth
(A) Support points S on both sides of the support frame 52 as shown in FIG.
The lower ends of the vibration-proof springs 53 are attached to ₁₀ and S _10, and the upper ends thereof are attached to the support points S ₁₁ and S ₁₁ of the outer casing 51. When changing from this state to the vertical installation, both anti-vibration springs 53 are removed from their supporting points S ₁₀ and S ₁₁ , and the sixth (b)
As shown in the figure, the supporting points S ₁₂ and S ₁₂ of the supporting frame 52 and the supporting points ₁₃ and S _{13 of the} outer casing 51 are hung on each other.

[Problems to be Solved by the Invention]

However, in the system shown in FIG. 5 in which one end of one vibration-proof spring is hooked up, the support frame 52 is
Is unstable in a vertical state, sometimes takes an oblique posture, and cannot sufficiently absorb vibration applied to the support frame 52.

Further, in the method shown in FIG. 6 (b), since the vibration-proof spring is completely removed when changing the posture, the vibration-proof spring is easily lost, and the work of replacing the vibration-proof spring is complicated.

In view of such a point, the present invention makes it easy to operate the spring associated with changing the posture of the disc reproducing apparatus, and it is not necessary to remove any one end of the vibration-proof spring, and there is no fear of loss. It is an object of the present invention to provide a disc reproducing apparatus that does not have a disc.

[Means for Solving the Problems]

Therefore, the present invention is directed to a disk reproducing apparatus in which a reproducing mechanism for positioning a disk at a predetermined position and reproducing information on the disk by a read head is housed in a supporting frame, and the supporting frame is floatingly supported by an outer casing. , At least one anti-vibration spring is provided between both side surfaces of the support frame and both side surfaces of the outer casing facing the support frame, and when the disc reproducing device is horizontally arranged, the end portion of the anti-vibration spring on the support frame side is provided. Is rotatably supported on a horizontal plane passing through the center of gravity of a floating-supported support frame including a reproduction mechanism, and the end portion of the vibration-proof spring on the outer casing side is attached to a support point on the outer casing side. Is configured to be rotatable in an arc shape on the outer casing by a predetermined angle.

[Action]

At least one surface is provided between the side surface and the side surface of the casing that faces the side surface of the support frame that supports the reproduction mechanism so that the apparatus does not become upside down even if the apparatus is horizontally or vertically installed.
Two anti-vibration springs are provided, and one end of the anti-vibration spring is rotatably attached to a casing side surface position on a plane passing through the center of gravity of the support frame when the device is horizontal, and the other end of the anti-vibration spring is outside. Attach it to the support point of the casing, and provide this outer casing side support point above the support point on the support frame side when the device is placed horizontally, and set the support point on the outer casing side when the device is changed from horizontal placement to vertical placement. Rotate the outer casing in an arc shape about 90 degrees so that it is located almost above the support point on the support frame side.

This eliminates the need to remove the anti-vibration spring when changing the posture of the device, facilitating the work, and supporting the support frame without tilting left and right when the device is placed vertically, thus absorbing vibrations. The effect is great.
