AI Technical Summary

Benefits of technology

The present invention relates to a disk recording-reproducing apparatus that uses a pickup to record and play data from a disk-shaped recording medium. The apparatus includes a tray for holding the recording medium, a drive section for self-propelling the tray, and a detection means for detecting the type of recording medium placed on the tray. The apparatus also includes a lock lever for locking the tray and a chucking slider for moving the base unit up and down. The technical effects of the invention include improved loading and unloading of recording media, reduced apparatus depth, and improved detection of recording medium type.

Problems solved by technology

As a disadvantageous effect, the entire apparatus will have a large depth due to the drive section and the optical pickup on the front of the turntable.

Embodiment Construction

(1) Description of the Configuration Overall Configuration

[0083]FIGS. 1 and 2 show an overall configuration of the disk recording-reproducing apparatus according to an embodiment of the present invention. The disk recording-reproducing apparatus has an external chassis 10 forming a flat, rectangular solid. A front panel 11 closes a front aperture of the external chassis 10. A horizontal aperture 12 is formed in the front panel 11. As shown in FIGS. 1 and 2, the horizontal aperture 12 allows a tray 13 to be freely inserted and ejected. A step section 18 is provided on each of both inner sides of the external chassis 10 The both step sections 18 support the tray 13 so that it can slide.

[0084] A recessed section 14 is formed approximately at the center of the tray 13. The recessed section 14 holds and supports a disk-shaped recording medium. An aperture 15 is formed across the recessed section 14 in a tray movement direction. The opening 15 has a U-shaped cut 16 farthest from the fr...

Abstract

A disk recording-reproducing apparatus ensures a large transport distance of a tray which moves a disk-shaped recording medium between an ejecting position and a recording-reproducing position while decreasing a dimension in the transport direction. A drive section (47) is built into a tray (13) which can be extracted from and retracted into an external chassis (10) and moves a disk-shaped recording medium between the ejecting position and the recording-reproducing position. A pinion (56) comprises an output end of the drive section (47) and rolls on a rack (24) of a chucking slider (20) to self-propel the tray (13). After the tray (13) completely moves to the recording-reproducing apparatus side, an output from the drive section (47) of the tray (13) is used to move the chucking slider (20) to the ejecting direction of the tray (13). Then, a cam groove (23) provided on the chucking slider (20) is used to raise a base unit (30).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a divisional of U.S. patent application Ser. No. 10 / 432,438 filed Sep. 5, 2003, which is the National Stage of PCT Application No. PCT / JP02 / 09580, filed Sep. 18, 2002.TECHNICAL FIELD [0002] The present invention relates to a disk recording-reproducing apparatus and more particularly to a disk recording-reproducing apparatus that uses a pickup to perform recording and / or reproducing by rotating a disk-shaped recording medium. BACKGROUND ART [0003] There is widely used a disk recording-reproducing apparatus that uses disk-shaped recording media such as a CD (compact disk), a DVD and an optical disk for recording and / or reproducing music and videos. Further, such disk-shaped recording media are used as storage devices for information processing apparatuses such as computers. [0004] In this case, the disk-shaped recording medium is mounted on a tray. Then, the tray moves from an ejecting position to a recording-reproduci...
