<p>Even if a recorded medium is exchanged during the reproduction of another recorded medium, the contents of the exchange work can be confirmed easily. A stocker accommodates a plurality of recorded medium carriers each holding a recorded medium. A first transport unit transports a recorded medium carrier between the outside of an apparatus housing and the stocker. A second transport unit transports a recorded medium between the stocker and a reproduction unit. The stocker is moved up and down in order to align the position of the recorded medium carrier with the first or second transport unit. While a recorded medium carrier is transported from the outside of the housing to the stocker, light emitting and receiving elements detect a presence/absence of a recorded medium. A control unit stores information of a presence/absence of a recorded medium at each stage of the stocker, and displays the contents of the information on a display unit. <IMAGE></p> |
