An opening and closing device of rotating cage type jukebox disc tray including a first disc tray carrying discs and an opening and closing mechanism of disc tray including a first linkage mechanism and a first driving device is provided. The first linkage mechanism includes a first linkage bar, a first sliding member and a second linkage bar. The second linkage bar is slidingly disposed on the first sliding member which is slidingly disposed on the first linkage bar. When an end portion of the second linkage bar is connected to a first ear portion on a lateral side of the first disc tray, the first driving device drives the first sliding member to slide on the first linkage bar, leading the second linkage bar to slide on the first sliding member and thereby leading the first disc tray to rotate around a first fixing post.

A disc transfer device according to the present disclosure is a disc transfer device that transfers a disc in a first direction from a first position toward a third position via a second position, and includes a roller, a roller support mechanism, a first retaining member, a second retaining member, and a retaining member support mechanism. The roller rotates in a state of contact with a disc end face on one side in a second direction being orthogonal to the first direction, until the disc reaches the third position from the first position. The roller support mechanism supports the roller such that the roller is in contact with the transferred disc and is moveable in the first direction and the second direction. The first retaining member extends in the first direction, and is brought into contact with the disc end face on the other side in the second direction until the disc reaches at least the second position from the first position. The second retaining member is brought into contact with the disc end face on the other side in the second direction until the disc reaches the third position from the second position. The retaining member support mechanism supports the second retaining member such that the second retaining member is in contact with the transferred disc and is moveable in the first direction and the second direction.

An opening and closing device comprises a disc tray, a mounting shaft and a jukebox manipulator. The disc tray is mounted on the mounting shaft. A positioning structure is provided between the disc tray and the mounting shaft. The mounting shaft is mounted on an outer circumference of a jukebox rotating cage. The jukebox manipulator is mounted on a manipulator driving unit. A side of the manipulator driving unit is provided with an optical drive, the jukebox manipulator is provided with a driving plate structure and the disc tray is provided with a driving lever. When the jukebox rotating cage rotates, the disc tray can revolve around the rotating shaft of jukebox rotating cage and can rotate around the mounting shaft. With the assistance of in-place bumping post which is provided by a side of the jukebox rotating cage, the positioning structure can locate the rotation of disc tray at a fixed static angle.

A disc device according to the present disclosure is a disc device for supplying a disc to each of a plurality of disc drives, and includes a carrier for retaining a plurality of discs in a stacked state, for separating one disc from the retained plurality of discs above a tray that is ejected from an arbitrary disc drive, and for placing the separated one disc on the tray. The carrier includes a first support claw that is capable of moving forward and backward below the plurality of discs, a second support claw that is capable of moving forward and backward into and out of a gap between a bottom disc and a disc that is adjacent to the bottom disc, among the plurality of discs, and a separation claw that is capable of moving forward and backward into and out of the gap and of pushing the bottom disc downward, where the bottom disc is separated from the retained plurality of discs by moving the first support claw, the second support claw, and the separation claw forward and backward, and pushing the bottom disc downward by the separation claw.

A cylindrical array of tightly spaced optical discs are each positioned vertically on edge to form a horizontal stack. Lifting a subset of optical discs enables that subset of optical discs to be grasped by their perimeters with much more room for robotic grippers between adjacent optical discs. An optical disc storage container includes a molded tray for vertically aligning a plurality of optical discs into the cylindrical array. The molded tray includes a bottom surface and side surfaces to support the optical discs and one or more openings formed in the bottom surface. A lifting mechanism is positioned along the one or more openings and is configured to lift the subset of optical discs a short distance relative to the remaining optical discs in the array, thereby enabling robotic grippers to grab the portion of the lifted optical disc protruding from the non-lifted optical disc array.
