Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a disc mounting device that can be applied to compact disc players and the like.

B. Prior Art A disk mounting device configured to mount the disk on a turntable by inserting the disk into a disk holding frame provided inside a lid body and then closing it is known, for example, from Utility Model Application No. 57- It is well known from No. 56369 etc. Considering the lid open state of such a disk mounting device, the lid and the disk holding frame are close to each other because the lid and the disk holding frame are linked and rotate within the same range. It will take some care to insert it.

C. Problems to be solved by the invention In this invention, the lid body and the disk holding frame are rotated in conjunction with each other, but by making the rotation ranges of the lid body and the disk holding frame different, the disk can be rotated in conjunction with the disk holding frame. It is intended to be inserted easily.

D. Means for solving the problem: A lid rotatably supported on the main body of the disc playback device, and a disc holder arranged inside the lid and rotatable to two positions: a playing position and a disc insertion position. A rotation range regulating means is provided to provide different rotation ranges to the frame, the lid body, and the disk holding frame.

E. Effect The rotation ranges of the lid and the disk holding frame are different depending on the rotation range regulating means. That is, even after the disk holding frame is prevented from rotating, the lid continues to rotate.
Therefore, the disc holding frame is located between the main body of the disc playback device and the lid in the open state, and the operation of inserting the disc into the disc holding frame becomes extremely easy.

F. Embodiment A bracket 2 is screwed to the bottom surface of a main body cabinet 1 of a disc playback device. This bracket 2 has recesses 2a and 2 that serve as pivot points.
b is formed (see Figure 1). The convex portion 3a provided on the disk holding frame 3 having the disk storage pocket 3c engages with the concave portion 2a of the bracket 2, so that the disk holding frame 3 is rotatably supported with respect to the cabinet 1. There is.
The upper part of the pocket 3c for storing the disk is the disk D.
It has a wide mouth for easy insertion. The disk holding frame 3 is constantly biased in the lid opening direction by a coil spring 4 (see FIG. 2). On the other hand, the convex portion 5b provided on the lid body 5 engages with the concave portion 2b of the bracket 2, so that the lid body 5 is rotatably supported with respect to the cabinet 1. The convex portion 5b is provided on a V-shaped piece 5a provided on the lid 5.

Now, FIGS. 1 to 3 show the closed state. In this state, the disk holding frame 3 is biased in the lid opening direction by the coil spring 4, and the tip 3b of the disk holding frame 3 in this state is in contact with the inside of the lid 5. Although the lid body 5 is also biased in the lid opening direction by the locking mechanism provided separately (as this is not the gist of the present invention,
(not shown) to maintain the lid closed state. When the lid is closed, disk D is at check 6.
and the turntable 7. The chuck 6 and turntable 7 are provided with well-known disk holding means composed of a magnet and a magnetic material. The turntable 7 is fixed to a drive shaft of a spindle motor 9 fixed to a mechanism chassis 8.

When the lock mechanism is released, the disk holding frame 3 and the lid body 5 are rotated in the lid opening direction by the biasing force of the coil spring 4. When the lid 5 rotates, the lid 5
The holding piece 5c formed on the chuck 6 engages with the chuck 6 and pulls the chuck 6 away from the turntable 7, and the chucking of the disc is released and the disc D
falls into the disk storage pocket 3c. Now, the rotation of the disk holding frame 3 is prevented by coming into contact with the front end 1a of the cabinet 1;
The lid 5 is further rotated by the V-shaped piece 5a and is prevented from rotating when the V-shaped piece 5a and the front end 1a of the cabinet 1 come into contact (see FIG. 4). That is,
The V-shaped piece 5a and the front end portion 1a constitute a rotation range regulating means 10.

FIG. 5 is a perspective view of the disk holding frame 3 seen from the rear, and 3d is a through hole for pick-up scanning.

Note that when the lid 5 is closed from the open state shown in FIG. 4, the centers of the disc D and the turntable 7, which are in contact with the bottom surface of the disc storage pocket 3c, are not far apart from each other to the left. The center hole of the disc D engages with the tapered part of the center protrusion of the turntable 7, and then the disc D is inserted along this tapered part.
is slightly raised, and the contact between the disk D and the bottom surface of the disk storage pocket 3c is released.

G. Effects of the invention According to the invention described above, the disc holding frame is located between the main body of the disc playback device and the lid when the lid is open, and the insertion of the disc into the disc holding frame is extremely difficult. It becomes easier.

[Brief explanation of drawings]

The drawings show the disk mounting device according to the present invention, and FIG. 1 is a front view, FIG. 2 is a sectional view, FIG. 3 is a sectional view showing the relationship between the lid and the cabinet, and FIG. 4 is a sectional view. FIG. 5 is a cross-sectional view with the lid open, and FIG. 5 is a perspective view of the disk holding frame. 1 is a cabinet, 3 is a disk holding frame, 5 is a lid, and 10 is a rotation range regulating means consisting of a front end portion 1a and a V-shaped piece 5a.
