Abstract: A disc player apparatus for moving a tray unit between the inside and the outside of an outer casing for loading a recording disc. The disc player apparatus includes a pickup device arranged on the tray unit for reading out the recorded information from a recording disc, a first driving unit for moving the tray unit between a position of being housed within the outer casing and a position of being protruded outwardly from the outer casing, a disc table supported on the tray unit for movement in a direction towards and away from the pickup device, and a second driving unit for moving the disc table on the tray unit in a direction towards and away from the pickup device. The disc table holds and rotates the recording disc. The second driving unit shifts the disc table to a position furthest from the outer casing in a range of possible movement of the disc table relative to the tray unit if the first driving unit moves the tray unit to the position of being protruded from the outer casing.
