Patent 7707597 was granted and assigned to Pioneer Corporation on April, 2010 by the United States Patent and Trademark Office.
A transport unit 41 includes a holding section 41A that holds a disc 11 and a transport section 41B that transports the disc 11. Since the disc 11 is held by the holding section 41A when the disc 11 is transported, the disc 11 is prevented from being disengaged from the transport section 41B, so that a transport distance of the disc 11 can be lengthened.
