The present invention relates to a disc reproducing device constructed such that a tray storing a disc can be loaded in and/or unloaded from a cabinet. In this disc reproducing device, a motor mounted with a disc motor and a turn table is constructed so as to be moved between the tray and a mechanical unit inside the cabinet. The tray has a pair of recessed portions as portions for holding the motor mount. The mechanical unit has as portions for holding the motor mount respective projecting portions of a pair of guide shafts for supporting a pick-up, a pair of lock levers, and a pair of guide projections. The pair of lock levers is also used as means for moving the motor mount between the tray and the mechanical unit.
