Patent ID: 7069567

Claim:
A disc device comprising: a disc driving section including a turntable; a transport roller operable to transport a disc towards the disc driving section; a positioning member disposed closer to a back side of the disc device than the disc driving section in a disc insertion direction, wherein an outer peripheral edge of the disc that is transported by the transport roller comes into contact with the positioning member and is positioned so that a central portion of the disc is set at the disc driving section; a detection section disposed closer to a front side of the disc device than the disc driving section in the disc insertion direction, the detection section being pushed and moved by the outer peripheral edge of the disc that is transported towards the disc driving section; a transmitting member operable to transmit movement of the detection section to the positioning member; a roller supporting member operable to move the transport roller to a transport position where the transport roller is capable of transporting the disc and to a retreat position where the transport roller is separated from the disc; and a restraining section disposed at the roller supporting member, wherein when the transport roller moves to the retreat position, the detection section is restrained by being moved in a predetermined direction by the restraining section, and the movement of the detection section when restraining the detection section is transmitted to the positioning member through the transmitting member, so that the positioning member moves so as to separate from the outer peripheral edge of the disc.
