Abstract: A frame structure of an electronic apparatus for containing a plurality of power supply units is disclosed. The frame structure includes a main frame, a tray, and at least one elastic element. The tray includes at least one fixing portion and is connected pivotally to the main frame to be in a first position or a second position. One end of each elastic element is fixed to the main frame, and the other end of each elastic element includes a fastening structure. When the tray is in the first position, each fixed portion is between the main frame and each elastic element. When the power supply units are placed into the main frame, each elastic element is pushed by the power supply units, and each fastening structure passes through the fixing portion and the main frame, for fixing the tray in the first position.

Abstract: The disc changer device, for transporting a tray to a stand-by position where trays are housed in a stacked state, to a disc exchange position where a disc on the tray is exchanged, as well as to a disc recording/reproducing position where a recording/reproducing operation is carried out on the disc on the selected tray, is provided with a plurality of tray locking units that are prepared in association with the respective trays, and engaged with a corresponding trays so that each of the corresponding trays is prevented from being transported from the stand-by position to the disc exchange position, and an engagement releasing unit for releasing engagement between the selected tray and the tray locking unit related to the selected tray as well as engagement between a tray adjacent to the selected tray on a lower side thereof and the tray locking unit related to the adjacent tray.

Abstract: An optical disk drive comprises a drive body, a spindle motor, an optical pickup device, a sled motor, a tray, a loading motor, and a controller. When the loaded optical disk is ejected, the controller controls the sled motor and the loading motor so that the returning of the optical pickup device and the opening of the tray are performed in non-chronological order. Accordingly, the time for the ejection of the optical disk is reduced.

Abstract: When a disk tray stops beyond or before a predetermined rotational position, there has heretofore been a likelihood of the disk tray being unable to be inhibited its rotation. As an arm portion 261b is displaced counterclockwise, a shaft portion 262b of a rotary stopper 262 moves toward an engaging groove 223, so that a sharp portion 262a1 is inserted into the engaging groove 223. At this time, slant faces formed on both sides of the tip of the sharp portion are guided along slant faces of the engaging groove 223 and are inserted to an inner part of the engaging groove. Thus, even when a rotary tray 220 stops at a position deviated from the predetermined rotational position, it is possible to surely inhibit the rotation of the rotary tray 220.
