As described above, according to the present invention, disc-shaped record carriers are inserted or ejected one by one through the opening of the housing. The plurality of record carriers are housed in a housing means arranged in the housing. Since the storage means can expand the space for advancing or retracting the reproducing means, the space for only storing the record carrier can be kept small. When the storage means is divided, the reproduction means is moved so that the reproduction means is arranged at a position in the housing outside the range where the storage means moves together with the record carrier, and above or below the transport means. It is possible to reduce the size of the housing by narrowing the space required between the opening of the housing and the storage means.

Furthermore, according to the present invention, the transport means arranged in the housing transports the record carrier between the opening of the housing and the storage means. Since the storage means can expand the space for advancing or retracting the reproducing means, the space for only storing the record carrier can be kept small. Further, since the carrying means and the reproducing means are arranged vertically, the space in the housing can be effectively used. When the record carrier is inserted or ejected, the reproducing means is arranged in the housing outside the range where the housing means moves together with the housed record carrier and above or below the carrying means. The space required between the opening and the storage means can be narrowed to reduce the size of the housing. According to the invention it is also possible to record information on a record carrier.
