Abstract:
1. An optical disc apparatus capable of carrying out an emergency eject motion of an optical disc, comprising: a disc moving mechanism moving said optical disc in an inner portion of the apparatus; a loading motor generating a driving force for driving said disc moving mechanism; and a transmission system structured such as to be provided with a gear and transmitting the driving force of said loading motor to said disc moving mechanism, wherein said transmission system is provided with a driven gear receiving the driving force from a gear in a previous stage, and a driving gear arranged so as to be coaxial with said driven gear and applying a driving force to a gear in the next stage, said driving gear is coupled in an inner diameter side of said driven gear so as to be movable in an axial direction and be rotatable integrally with said driven gear, said driving gear is structured such that said coupling with said driven gear is canceled in a state of being kept engaged with the gear in the next stage, by moving and displacing in an axial direction with respect to said driven gear.
