Embodiment Construction

[0075] Referring to the accompanying drawings, a first preferred embodiment of a disk drive apparatus according to the present invention will now be described in detail.

[0076] Referring now to the attached drawings, especially Figures 1 to 8 , shows a first preferred embodiment of the disk drive apparatus according to the present invention. The disc drive apparatus 100 is designed to drive an optical disc having a central portion formed with a central hole. The disc is rotatable about an axis of rotation passing through its central bore.

[0077] figure 1 4, the disk drive apparatus 100 includes: a frame member 110; and a disk lock member 120 supported by the frame member 110, and the disk lock member 120 is rotatable about its rotation axis.

[0078] The disk locking member 120 has: a cylindrical shaft portion 121; and a locking portion 122 integrally formed with the shaft portion 121 of the disk locking member 120 and radially outward extend. The locking portion 12...

Abstract

Herein disclosed is a disc drive apparatus for driving an optical disc having a central portion formed with a central hole, comprising: a frame member, a disc retaining member rotatably supported by the frame member, a cam member supported by the disc retaining member and rockable with respect to the disc retaining member, a plurality of disc holding members each supported by the disc retaining member and operatively coupled with the cam member, each of the disc holding members being movable with respect to the disc retaining member to assume two different operation positions including a disc holding position in which each of the disc holding members is held in contact with the central portion of the optical disc, and a disc releasing position in which each of the disc holding members is held out of contact with the central portion of the optical disc, and a resilient member intervening between the disc retaining member and each of the disc holding members to have each of the disc holding members resiliently urged to assume the disc holding position.

Description

technical field [0001] The present invention relates to a disc drive device for driving an optical disc, and more particularly to a disc drive device equipped with a disc holding mechanism which detachably holds an optical disc thereon. Background technique [0002] Hitherto, there have been proposed various conventional disk drive devices designed to drive an optical disk having a circular hole formed in a central portion, such as a compact disk (CD) and a digital versatile disk (DVD). Heretofore, such conventional disk drive devices are used in various information recording and / or reproducing devices. Japanese Patent Laid-Open No. 10-134462 and No. 10-269722 disclose the conventional disk drive apparatus proposed above. [0003] A typical example of a conventional disk drive device is a mandatory mount type conventional disk drive device. A conventional disc drive of this type includes: a disc lock formed with a circumferential shoulder; a plurality of di...
