FIG. 1 shows an embodiment of a compact disc mounting device of the present invention.
It is sectional drawing when 8 cmCD and 12 cmCD are mounted. FIG. 3 is a sectional view showing the movement of each component when the same 12 cm CD is mounted. FIG. 4 is a cross-sectional view showing the components shown in FIG. 3 after being moved. FIG. 5 is a sectional view showing the state after the movement of each component when the 8 cm CD is mounted. FIG. 6 is a partial sectional view showing the movement of each component. As shown in FIG. 2, the guide wall 3b and the receiving portion 3c provided on the guide member 3 constitute a guide portion of 12cmCD6, and the peripheral wall portion 3d and the receiving portion 3e similarly form 8cmCD7.
Constitutes the guide part. The receiving portion 3c is formed with a mortar-like inclination from the peripheral wall portion 3b toward the inner peripheral wall portion 3d, and the guide member 3 is rotatably fixed to the cabinet 1 by the guide member support shaft 3a. The disk lid 2 to which the clamper portion 5 is attached is also rotatably fixed to the cabinet 1. Similarly, the disk drive unit 4 is fixed to the disk drive unit mounting boss 1a of the cabinet 1. When the 12 cm CD 6 is placed on the receiving portion 3c along the peripheral wall portion 3b of the guide member 3 with the disc lid 2 open, it becomes a slanted state.
Further, when the 8 cm CD 7 is placed along the peripheral wall portion 3e, it is directly mounted on the turntable 4a. As shown in FIG. 3, when the disc lid 2 is closed, the guide member 3 starts moving around the guide member support shaft 3a as a fulcrum. The 12 cm CD 6 moves in the same manner as the guide member 3, and as shown in FIG. 4, it is mounted on the turntable 4a and held between the clamper portion 5 mounted on the disc lid 2 and the turntable 4a. Further, as shown in FIG. 5, since the 8 cm CD 7 is mounted on the turntable 4a from the beginning, it is held by the clamper 5 and the turntable 4a regardless of the movement of the guide member 3. As shown in FIGS. 2 to 6, a holding portion 2b is provided on the disc lid leg 2a of the disc lid 2 or the like so that the guide member 3 is interlocked with the rotation of the disc lid 2. As a result, the guide member 3 moves upward when the disc lid 2 is opened, and the guide member 3 moves downward when the disc lid 2 is closed. Further, by making the surface of the receiving portion 3c of the guide member 3 into a mortar shape, even if the disc lid 2 is opened while the CD is rotating, the guide member 3 that is going to move upward has a 12 cm
Since only the outer edge of the CD6 contacts, scratches on the recording surface can be prevented. In the case of 8 cm CD7, the vertical wall of 8 cm + α of the guide member 3 serves as a guide, which prevents the guide member 3 from coming off the turntable 4a.

In this embodiment, the guide member 3 rotates,
The entire guide member 3 may move in the vertical direction. Further, the spot facing for guiding may be formed in a rib or pin shape.

As described above, the compact disc mounting device of the present invention is
A disk drive unit fixed to the cabinet, on which the disk is mounted, a disk lid that faces the disk drive unit and is openable and closable, and has a clamper that presses the disk against the disk drive unit; A disc guide member configured to be rotatable with respect to the cabinet so as to be guided on the turntable of the disc drive unit in association with opening and closing of the disc drive unit, the disc guide member being a receiving unit for discs having different diameters. And a guide portion composed of a peripheral wall portion, a notch portion is formed at a position corresponding to the disc drive portion, and the receiving portion of the small diameter disc guide portion is configured not to be located on the turntable even when the disc lid is opened. , Further, the receiving part of the guide part for the large diameter disc is inclined toward the peripheral wall part of the guide part for the small diameter disc. When the disc lid is closed, each guide portion of the disc guide member is configured to move to the rear position from the clamp surface of the disc, thereby facilitating the mounting of the disc and the rotation of the disc. It is possible to prevent the disc from coming off from the turntable when the disc lid is opened, and to prevent scratches on the recording surface of the disc.

Moreover, when a small-diameter disc is mounted, it is mounted directly on the turntable with the disc lid open, and there is no direct contact with the guide member of the disc, so that scratches on the recording surface of the disc can be reliably prevented. Further, when the large-diameter disk is mounted on the guide member, the contact of the disk with the inclined receiving portion is only with the outer peripheral end surface, so that the recording surface of the large-diameter disk can be surely prevented from being scratched. It is a thing.
