Problems solved by technology

[0004] However, the prior art slot-in type optical disk drive 10 rotates the transmission rod 12, although the worm wheel 14 can be driven to drive the gear set 15 to rotate and eject the optical disk in an emergency.
However, the worm gear 14 with low lead still needs a long time to drive the gear set 15 to rotate the roller 16 to complete the ejection of the optical disc, which cannot meet the needs of rapid ejection maintenance.
Therefore, the prior art slot-in optical disc drive still has problems on the emergency ejection mechanism, which needs to be solved urgently.

Embodiment Construction

[0051] In order to achieve the above object, the present invention adopts the technical means and its effects, hereby give preferred embodiments, and illustrate as follows in conjunction with the accompanying drawings.

[0052] Please also refer to figure 2 and image 3 , figure 2 For the slot-in optical disk drive 20 of the present invention, image 3 It is an enlarged view of the emergency film ejection device of the present invention. The slot-in optical disc drive 20 includes a housing 21 with a hollow interior, a front end with a roller 22 to push in or out the disc by forward and reverse rotation, and an ejection hole 23 nearby, the ejection hole 23 can respond to an emergency ejection device The configuration of 24 is located at the front end or side of casing 21.

[0053] The slot-in CD player 20 is powered by the self-locking power unit 30 to drive the transmission gear set 31. The transmission gear set 31 is composed of a plurality of gears connected in series....

Abstract

An emergency ejection device is disclosed for a slot-in optical disc drive. A thin stick inserts into an ejection hole to rotate an ejection plate for an emergency ejection. A guide pin slides along a guide slot to rotate a release bar such that a clutch gear at the other end of the release bar departs from a self-locking power unit. Then the ejection plate moves a rack to rotate a ratchet unit at a predetermined direction for driving a transmission gear unit to unload a disc.

Description

technical field [0001] The invention relates to a slot-in optical disc drive, in particular to an emergency ejection device for ejecting optical discs by manual operation under abnormal conditions such as faults or power failures of the slot-in-type optical disc drive. Background technique [0002] The slot-in optical disc drive mainly uses the gear set to drive the lever, rollers or tires to guide the disc to advance and retreat. When the power is cut off or fails, the disc cannot be automatically ejected, and the disc needs to be disassembled to take out the disc. However, ordinary users cannot easily disassemble the slot-in disc drive, especially the slot-in disc drive installed in car audio, computer or high-end audio-visual equipment, and professional technicians are needed to remove the disc. [0003] Such as figure 1 As shown, it is the prior art slot-in optical disc drive of the United States Publication No. US8042128 patent case. The prior art is a roller type slot...
