Disc roller position-changing apparatus and disc player having the same

A disc roller position-changing apparatus and a disc player having the same are provided. The disc roller position-changing apparatus includes a movable hinge part for supporting the roller bracket on a main chassis such that the roller bracket is movable by a predetermined distance and pivotal, a protrusion part formed on the roller bracket, and a slider installed to be capable of reciprocating in a disc loading direction and selectively connected to a power transmission unit for transmitting power from a driving motor depending on its moving position, thereby being reciprocated. The slider has a guide slot part for receiving and guiding the protrusion part. Because the disc roller position-changing apparatus supports a disc roller such that the disc roller is movable by a predetermined distance when the disc roller is contacted with or separated from a disc, it is possible to reduce the operating space of the roller bracket and the height of a guide slot part, and as a result, it is possible to slim a resultant disc player having such a disc roller position-changing apparatus.
