ABSTRACT:
A disk reading device has a housing having a disk receiving space provided therein, a first rod having a first guide pin, a second rod pivotably coupled to the first rod at a pivot point in a manner such that the first and second rods achieve a scissoring movement about the pivot point, with the second rod having a second guide pin. The device also includes a locking mechanism for locking the first and second rods at a fixed position, and a detection mechanism coupled to the first rod for detecting the size of a disk that is being inserted into the disk receiving space. The locking mechanism unlocks the first and second rods when a disk having a first size contacts the detection mechanism, and the locking mechanism maintains its lock on the first and second rods when a disk having a second size smaller than the first size is inserted into the disk receiving space.
