Abstract

The invention relates to a CD player. For a traditional socket CD player, it has the following characteristics: it is composed of a CD output guiding inclined plane whose height gradually expands from outside of its entrance inward. Thus, even if the size of the entrance is reduced, it can still improve the reliability of the CD output course; besides, prevent pollutants from flowing from the entrance onto the CD, thus able to effectively protect the CDs and the CD player so as to reduce the invading danger of external pollutants to them.

Description

【Technical field】 [0001] The present invention relates to an optical disc player. Specifically, for a slot-type optical disc player, even if the size of the inlet is reduced, the reliability of the disc ejection process can still be improved. At the same time, it can prevent pollutants from flowing into the optical disc from the inlet side, thereby effectively protecting the optical disc and the optical disc player, and reducing the risk of the optical disc and the optical disc player being infringed by external pollutants. The present invention relates to an optical disc player having the above features. 【Background technique】 [0002] Recently, the number of data storage devices and AV equipment using optical disc players has increased rapidly, and various types of products have entered the market. Among them, the growth of DVD playback devices has attracted the most attention. Generally, in an optical disc player, the portion for storing the optical disc is designed in...
