Abstract
An apparatus for recording and/or reproducing a disc-shaped recording medium. A medium is placed on each of a plurality of placement members. The members are stacked and housed in a housing unit. An elevating mechanism elevates the housing unit in the direction almost parallel to the stack direction of the members. A carrying mechanism carries one of the members among a position where a medium can be placed or ejected to/from the member, a position where the member is housed in the housing unit and a position where the medium placed on the member is loaded to the recording and/or reproducing unit. A driving source drives both the carrying mechanism and the elevating mechanism. A switching mechanism selectively supplies a driving force from the driving source to the carrying mechanism and the elevating mechanism. A photodetector detects the presence/absence of the medium on the members in the housing unit.
