A tray locking device adapted to an optical disc drive for locking and releasing a tray is provided. The optical disc drive has an optical head connected to a lead screw and driven to move by the lead screw. The tray locking device includes a pushing member driven to move by the lead screw, a latching hook for locking and releasing a protruding pin, and a transmission assembly configured between the pushing member and the latching hook. The transmission assembly includes a first rod and a second rod movably configured in the tray. The first rod has a first driving portion, and the second rod has a second driving portion. When the transmission assembly is located at an initial position, the first driving portion is located on a moving path of the pushing member, while the second driving portion is not located on the moving path of the pushing member.

Tray locking device for optical disc drive

An optical disc drive is provided. The optical disc drive includes a housing having a protruding pin, an optical head engaged to a lead screw, a tray slidably disposed in the housing and a tray locking device disposed on the tray. The tray locking device includes a pushing member, wherein the pushing member and the optical head are driven by the lead screw to move, a latching hook used to latch and release the protruding pin, and a transmission assembly disposed between the pushing member and the latching hook. The transmission assembly has a driving portion disposed on a moving path of the pushing member, wherein the pushing member pushes the driving portion so that the transmission assembly is actuated and drives the latching hook to release the protruding pin.

Optical disc drive and tray locking device thereof

A tray locking device of an optical disc drive is adapted to lock and release a tray. The optical disc drive has an optical head engaged to a lead screw and driven to be moved by the lead screw. The tray locking device includes: a pushing member, disposed on the optical head; a first stop portion, disposed on the tray; a latching hook, adapted to latch and release a pin; and a transmission assembly, disposed between the pushing member and the latching hook and having a lever element and a weight block, wherein the lever element is movably disposed on the tray and has a second stop portion, and the first stop portion and the second stop portion can be coupled with each other.

Tray locking device of optical disc drive with anti-shock mechanism

An optical disk drive including a housing, a top cover, a spindle motor and a supporting element is provided. The housing has an accommodating space. The top cover covers the accommodating space. The spindle motor is disposed within the accommodating space and has a shaft. The supporting element is disposed between an end of the shaft and the top cover. When the top cover is deformed, the shaft props up the top cover through the supporting element.

Optical disk drive

A slot-in optical disc drive is provided to comprise a driving element moveably disposed in the optical disc and capable of moving toward a disc loading direction and a disc unloading direction, wherein the driving element has a loading drive groove; a disc loading element pivoted in the optical disc drive, wherein the disc loading element has a loading driven pin for operating with the loading drive groove; a disc unloading element pivoted in the optical disc drive; and an elastic element used for providing an elastic force on the disc unloading element.

Slot-in optical disc drive with disc loading/unloading mechanism

A disk drive includes an insert-and-eject device and a disk guide unit. The insert-and-eject device is used for inserting and ejecting a disk. The disk guide unit includes a rack and a slide member connected to the insert-and-eject device in such a manner that reciprocal movement of the disk guide unit along a first direction permits the slide member to drive the insert-and-eject device to insert and eject the optical disk from the disk drive. An emergency release device is mounted on the slide member, and includes a horizontal element movable along a second direction. The rack is formed with a retention groove such that the movement of the horizontal element along the second direction permits a the horizontal element to extend within or exit the retention groove so as to couple the slide member with the rack or to disengage the slide member from the rack.
