Abstract
A disc transfer section for transferring an optical disc by guide members and a transfer roller is disposed adjacent to an opening of a casing. A detectorfor detecting the optical disc is disposed adjacent to the opening. When unloading the optical disc, the peripheral edge of the optical disc contacts with slide members so that the slide members are slid, thereby sensor switches SWto SWare appropriately switched on and off. Based on a time difference between the timings of the on/off switchings, the relation between a movement trajectory of the center of the optical disc and an axis of symmetry that is a straight line indicating a transfer direction at the center of the opening is judged in order to control the drive of a transfer motor according to the movement trajectory. The amount of advancement when the unloading is completed is kept constant.
