ABSTRACT:
In order to prevent any scratches from occurring at a back-end edge of a disk when a feeding roller finishes ejecting the disk and a user tries to grab and draw out the disk, a second ridge disposed on a side of an opening for inserting the disk of two ridges located on both sides of the feeding roller is made up of a straight part without any gradient for a specified range in a central part, a first tapered part with a sharp gradient within a specified range on both sides thereof, and a second tapered part with a gentle gradient on both sides further thereto. When the disk is drawn out for ejecting, only the back-end circumferential periphery of the disk point-contacts the first tapered part with a sharp gradient and accordingly it is possible to prevent any damage to the disk due to any possible line contact between the disk and the ridges.
