Description

  The present invention relates to a disk device that performs recording or reproduction on a disk-shaped recording medium such as a CD or DVD, and more particularly to a slot-in type disk device that can directly insert or eject a disk from the outside.

Conventional disk devices often employ a loading method in which a disk is placed on a tray or turntable, and the tray or turntable is mounted in the device body. In such a loading method, the tray or turntable is used. There was a limit to making the disk drive body thinner as much as a table was required. Therefore, recently, there is a slot-in type disk device in which a disk is directly operated by a lever or the like by a loading motor (for example, Patent Document 1).
In the apparatus of Patent Document 1, a lever disposed at the right front part in the apparatus realizes disk pulling and disk holding during disk chucking. This lever performs each operation by a cam provided on an upper surface portion of a slider disposed on the side of the traverse in the apparatus. The slider is also provided with a cam for raising and lowering the traverse on the side surface, and the disk pulling lever and the traverse are moved in a timely manner by the back and forth movement of the slider, thereby realizing disk conveyance, chucking, and the like.
