A CD-ROM reader mechanism includes a movable inner frame supporting a reader device thereon and being movably received in a fixed outer frame. At least one pair of flexible hinges are integrally formed between the inner frame and the outer frame at opposite sides to pivotally support the inner frame in the outer frame thereby allowing a front end of the inner frame to move between an upper position where the reader device is allowed to access an optic disk and a lower position where the reader device is moved away from the optic disk. The flexible hinges each include an undulated structure made of a deformable material. The undulated structure has a plurality of cavities therein which allow the structure to collapse for serving as a hinge.
