Abstract

An emergency disc ejecting device for an optical disc drive including a linkage module and a gear module is provided. The linkage module has a first linkage capable of moving along a disc loading direction and a disc ejecting direction. The gear module includes a first gear, a second gear and a pulley. The first gear is detachably connected to the first linkage. The second gear is driveably connected to the first gear and has a first contacting portion. The pulley is pivoted on the second gear and has a second contacting portion, wherein the second gear has an idle-stroking rotation relative to the pulley. When the second gear performs the idle-stroking rotation relative to the pulley, the first contacting portion moves relatively from a first side of the second contacting portion to a second side of the second contacting portion.

Description

technical field [0001] The present invention relates to an unwinding device of an optical drive, and in particular to an emergency unwinding device of an optical drive. Background technique [0002] In recent years, with the development of information technology, computers have become an indispensable and important item in our daily life. In order to make the functions of computers more diversified, computer peripheral products have become an important tool for computer expansion. As far as the data storage medium is concerned, the storage device for storing data and the reading device for reading the storage device have also become the focus of computer peripheral products. Among them, due to the advantages of cheap price, convenient portability, large storage capacity, easy storage, long shelf life and no damage to data, optical discs have gradually replaced traditional magnetic storage media. Due to the widespread use of optical discs, optical drives that can be used to...
