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. 10 (a) and 10 (b), the CD disc reproducing apparatus 50 has an outer casing 51, and a supporting frame 52 is provided in the outer casing 51, and a vibration isolating spring is provided at the center 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. 10 (a)). When the disc reproducing apparatus is placed vertically, as shown in FIG. 10 (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. This transfer operation was performed by opening the cover or the like provided on the outer casing 2.

[Problems to be Solved by the Invention]

However, in the method of changing the vibration-proof spring as described above, after the cover is closed after changing it, the mounting position of the vibration-proof spring cannot be confirmed from the outside and the suspension is not suitable for the usage posture. There was a risk of using it in the state.

In view of the above point, the present invention has an object to provide a disc reproducing apparatus in which the suspension state of the vibration-proof spring can be reliably confirmed from the outside of the outer casing and the support frame is not supported in an incorrect suspension state. .

[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 vibration-proof spring is provided between both side surfaces of the support frame and both side surfaces of the outer casing facing the support frame, and one end of the vibration-proof spring is rotatably supported by the support frame. The outer casing side end of the above is attached to a rotating member that is rotatably attached to the outer casing, and a confirmation mechanism that can confirm the rotating position of this rotating member from the outside of the outer casing is provided.

[Action]

At least one anti-vibration spring is provided between the side surface and the side surface of the outer casing that faces the side surface of the support frame that supports the reproduction mechanism so that it does not become upside down when the apparatus is placed horizontally or vertically. One end of the anti-vibration spring is rotatably attached to the support frame, and the other end of the anti-vibration spring is attached to a rotating plate rotatably attached to the outer casing. A mechanism for confirming the position of the rotating plate is provided between the rotating plate and the outer casing, and the position of the rotating plate is always confirmed from the outside.

As a result, the vibration-proof spring adapted to the posture of the apparatus can be in a suspended state.

The magazine M is stored in the support frame 3 through the opening 5 on the front surface of the support frame, and then the trays in the magazine M are kicked out one by one by a kicking device (not shown). The t is positioned at the position shown in the figure, and at this position, the compact disc d is held by a clamp arm (not shown) and rotated at a predetermined rotation speed so that the information on the compact disc d can be read by the pickup.

The disc reproducing apparatus 1 is used by being placed horizontally as shown in FIG. 1 or vertically placed by raising it 90 degrees vertically from the state of FIG. The disk is housed in the trunk, and the desired disk d is kicked out together with the tray to the position shown in FIG. 1 by operating the operation panel in the cab, and the information on the disk is read by the pickup.

Between the side surface 3a of the support frame 3 and the side surface 2a of the outer casing 2, a pair of anti-vibration springs 11, 11 are provided on one side of the device 1 with a space therebetween. The both side surfaces 2a and 3a are the device 1
It is a surface that does not have a top-bottom relationship regardless of whether it is placed horizontally or vertically. The anti-vibration springs 11 cooperate with the damper 4 to absorb the vibration of the support frame 3 when the vehicle vibrates. The lower end of the anti-vibration spring 11 is rotatably attached to the 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 attached to the side surface 2a of the outer casing. The protruding end 12 of the rotating plate 12
It is stuck to a. The rotating plate 12 is shown in FIG.
As shown in the figure, a support shaft 13 is pivotally attached to the side surface 2a of the outer casing 2, and the rotary plate 12 is provided with arc-shaped openings 14 and 15 which are point-symmetrical with respect to the support shaft 13. . These arc-shaped openings 14 and 15 are 90 degrees centered on the support shaft 13.
This arc-shaped opening 14,1 is formed over an angular range of degrees.
5 includes a guide shaft 16 fixed to the side surface 2a of the outer casing,
17 are engaged with each other. Further, belleville springs 18 are provided between the rotating plate 12 and the side surface 2a of the outer casing 2, and the bevel spring 18 stops the rotating plate 12 at a predetermined position.

The support shaft 13 is fixed to the rotating plate 12 and is rotatably attached to 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 its center,
