Disk guide apparatus for optical disk playback system to prevent misinsertions

摘要

A disk guide apparatus for an optical disk playback system includes a pinion gear having at least one non-toothed portion, a pair of guide plates respectively having a gear portion being engaged to the pinion gear, and a spring providing an elastic restoration to the guide plates. The apparatus prevents an erroneous insertion of the optical disk and carries out a disk loading/unloading operation by use of minimal parts thereof, thereby realizing a simplified structure and an easy assembly as well as decreasing production cost and improving workability.
