Embodiment Construction

[0016] figure 1 It is a perspective view of an optical drive according to an embodiment of the invention. figure 2 for figure 1 Schematic diagram of the tray ejecting the optical drive. image 3 for figure 1 Schematic diagram of the tray locking device of the optical drive. Please refer to Figure 1 to Figure 3 The optical drive 100 of this embodiment includes a housing 110, an optical head 120, a tray 130, a lead screw 112, and a tray locking device 140. The optical head 120 is engaged and connected to the lead screw 112, and when the lead screw 112 rotates, the lead screw 112 drives the optical head 120 to move on the lead screw 112 relatively. The tray 130 is movably arranged in the housing 110 and has a locking position (such as figure 1 Shown) and an exit position (e.g. figure 2 Shown).

[0017] The tray locking device 140 of the embodiment of the present invention includes a transmission assembly 142, a pushing member 144 and a hook 132. The hook 132 is pivotally dispose...

Abstract

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.

Description

Technical field [0001] The invention relates to a tray locking device, and in particular to a tray locking device of an optical drive. Background technique [0002] The more mature the computer is, the more types of data can be processed by the computer, and the greater the storage capacity required. Since optical disks have the advantages of low price, convenient portability, large storage capacity, easy storage, long shelf life, and difficult data damage, optical disks have gradually replaced traditional magnetic storage media and have become an indispensable light for modern people. Storage medium (opticalstorage medium). With the widespread use of optical discs, optical drives used to read data on optical discs have also become indispensable electronic products in life. [0003] Generally speaking, an optical head (optical head) is arranged inside the optical drive, and driving components such as a screw drive the optical head to move back and forth, so that the optical head ...
