Abstract: An optical disk mechanism has a housing with at least one disk entry/exit aperture. A disk guide, such as a plate, is aligned with and guides an optical disk through the disk entry/exit aperture. Two beams rotatably support at least one roller and a drive mechanism. Flexing and biasing the roller towards the disk, the two beams maintain a rotational axis of the roller parallel to the disk and accommodate varying separation between the roller and the disk guide. The two beams are closely spaced and non-coplanar, and may be part of a double-beam mount. The double-beam mount attaches the two beams to the housing and to a frame, which positions the roller near the disk guide and the disk entry/exit aperture. Sliding the disk along the plate or other disk guide, the roller is reversible to drive the disk in or out through the disk entry/exit aperture.

Abstract: An optical disk cassette has a disk eject mechanism that ejects a disk such as a DVD or CD. The disk eject mechanism has pushrod, transfer and kick out portions. The pushrod portion slides relative to a side of the cassette case. Pivotally mounted within the case, the kick out portion pushes a disk to eject it from the case. The transfer portion translates pushrod motion to motion of the kick out portion. In a preferred embodiment, the disk eject mechanism is a unitary body, with pushrod, transfer and kick out portions made homogeneously as a single entity, the pushrod portion being a resilient joining elbow. In another preferred embodiment, the disk eject mechanism has a transfer portion that is a rack and a pinion. The rack extends from the pushrod portion and the pinion is attached to or formed as part of the kick out portion.
