ABSTRACT:
The invention makes it possible to carry out an emergency eject motion without attaching and detaching teeth between gears in a transmission system of a driving force of a loading motor, in an optical disc apparatus. At least one of gear units in a gear train constructing a transmission system between a loading motor and a disc moving mechanism is structured such that a driving gear is coupled in an inner diameter side of a large diameter driven gear in such a manner as to be movable in an axial direction and be rotatable integrally with the driven gear, and the driving gear moves and displaces in an axial direction with respect to the driven gear, thereby being canceled the coupling with the driven gear while keeping an engagement with a gear in the next stage, canceling the coupling by an external force by a manual operation so as to set the transmission system to a disconnection state at a time of an emergency eject, making the disc moving mechanism carry out a disc discharge motion by the external force, and discharging an optical disc out of the apparatus.
