Problems solved by technology

[0008] However, in the suction method proposed in Patent Document 1, for example, since a conveying roller longer than the diameter of the optical disk is used, the width of the device must be increased, and the thickness of the device must also be increased due to the existence of the conveying roller.
[0009] Therefore, in such a slot-in type optical disc device, it is difficult to realize thinning and miniaturization of the optical disc device body.

Abstract

A disc drive in which sufficient rigidity can be attained even when a material of low rigidity, e.g. an aluminum alloy or a magnesium alloy, is employed and malfunction due to deformation of the chassis enclosure can be prevented. The chassis enclosure is constituted of a base body (10) and a lid body, a disc insertion opening (11) for inserting a disc directly is formed in the front surface of the chassis enclosure, a deep bottom part (210) and a shallow bottom part (310) are formed in the base body (10), the shallow bottom part (310) is arranged on the side part of the deep bottom part (210), and the deep bottom part (210) and shallow bottom part (310) are covered with the lid body. The disc drive is characterized in that a first squeezing groove (136A) of a predetermined length projecting toward the base body (10) side, and a second squeezing groove (136B) of a predetermined length projecting toward the side opposite to the first squeezing groove (136A) are formed at the front surface side end part of the lid body.

Description

technical field [0001] The present invention relates to an optical disc device for recording on or reading from a disc-shaped recording medium such as a CD or DVD, and more particularly to a so-called slot-in type optical disc device in which an optical disc can be directly inserted or ejected from the outside. Background technique [0002] Most of the existing optical disk devices adopt a loading method in which the optical disk is placed on a tray or a turntable, and the tray or turntable is installed in the device body. [0003] However, in such a loading method, the space required for the tray or the turntable is a limitation for reducing the thickness of the main body of the optical disc device. [0004] On the other hand, for a suction-type optical disk drive, a method has been proposed in which a transport roller is brought into contact with the surface of the disk to suck the disk in (for example, Patent Document 1). [0005] In addition, as a slot-type optical disc...
