Abstract: Provided is an optical disc drive that can implement a conveying roller position manipulation mechanism, a centering mechanism, and a chucking pulley operation mechanism, while allowing the number of components to be reduced. A base frame includes a spindle motor and an optical element. An inner case houses the base frame, and supports a conveying mechanism configured to convey an optical disc to the position of the spindle motor. An outer case houses the inner case. The base frame is fixed in the inner case via a first damper, and the inner case is fixed in the outer case via a second damper.

Abstract: There is provided an optical disc drive that can maintain contact between an optical disc and a conveying roller, while allowing the number of components to be reduced. A conveying roller includes a right roller that is rotatable around an axis and a left roller that is rotatable around an axis. The right roller portion and the left roller portion are arranged in a lateral direction. One of a right end portion of the right roller portion and a left end portion of the left roller portion is movable in an up-down direction relative to the other of the right end portion of the right roller portion and the left end portion of the left roller portion, with a relative position between the axis and the axis unchanged.
