Claim 4:
5. An optical disc drive, comprising:
a spindle motor;
a chucking pulley configured to fix an optical disc to the spindle motor;
a conveying roller configured to convey, toward a position of the spindle motor, the optical disc inserted through an insertion port;
a conveying roller position manipulation mechanism configured to move a position of the conveying roller between a first roller position where the conveying roller contacts the optical disc and a second roller position where the conveying roller is separated from the optical disc;
a centering mechanism configured to align a center of the optical disc with the position of the spindle motor; and
a chucking pulley operation mechanism configured to manipulate a position of the chucking pulley, wherein:
the conveying roller position manipulation mechanism includes a movable member configured to move in response to a collision with the optical disc that approaches the position of the spindle motor,
at least one of the centering mechanism and the chucking pulley operation mechanism includes a member coupled to the movable member,
the centering mechanism includes a contact portion and a bias member, the contact portion being configured to come into contact with an outer edge of the optical disc that moves toward the position of the spindle motor, the bias member being configured to use the contact portion to align a center of the optical disc with the position of the spindle motor, and
the movable member engages with the bias member and, when the optical disc reaches the position of the spindle motor, moves the bias member such that the contact portion moves away from the optical disc.
