The housing 600 is provided with a locking device 610 so that the tray 500 is inserted into and caught by the housing 600, and also has a compressive force for pushing the tray 500 from the housing 600. A take-out device 620 is provided.

A locking jaw 540 is installed on the bottom of the tray 500 so as to catch the locking device 610 installed in the housing 600, and a disk D is provided on an upper surface of the tray 500. ), A turntable 510 for clamping the disk D, a spindle motor 520 for rotating the turntable 510, and an optical pickup unit for reproducing data recorded on the disk D. 530.

The locking device 610 is composed of an actuator 611 and a locking member 617. The actuator 611 is fixed to the embossed portion 615 of the housing 600 by a screw 616, and is installed to be slidably protruded and inserted into the stator 612 and the stator 612. 613 and a locking spring 614 provided between the iron core 613 and the stator 612 to provide a pressing force to protrude the iron core with respect to the stator 612. The actuator 611 generally uses a solenoid that linearly moves by an electrical signal. The locking member 617 is supported by a shaft 618 installed on the upper surface of the housing 500, one end of which is connected to the iron core 613, and the other end of the locking member 617 is disposed on the tray 500. The end is formed to protrude so as to connect to.

Therefore, when the actuator 611 is not operated, the locking member 617 coupled to the iron core 613 maintains the locking jaw 540 in the locking jaw 540 by the locking spring 614.

The take-out apparatus 620 is installed to be fixed to the upper surface of the housing 600, the first support 622 and the second support 623 is spaced apart a predetermined interval, the first support 622 and the second The takeout lever 621 is fixed to the pedestal 623. The support part 624 is installed in the takeout lever 621 so as to be slidable along the takeout lever 621 adjacent to the second support 623. In addition, a compression spring 625 is installed between the support part 624 and the first support 622 to surround the take-off lever 621. That is, the ejection lever 621 is installed through the compression spring 625. The shape of the take-out lever 621 may be a plate or rod as long as the take-out lever 621 is installed inside the compression spring 625.

In addition, a pushing table 550 is installed at a bottom of the tray 500 to correspond to the support part 624 that is slidably installed at the take-out lever 621. As the tray 500 is inserted into the housing 600, the pushing unit 550 pushes the support 624 in the direction in which the tray 500 is inserted into the housing 600, thereby supporting the support 624. By compressing the compression spring 625 supported in the ()) and the take-out lever 621 is elastically biased in the direction in which the tray 500 protrudes.

The tray 500 of the optical disk drive 400 according to the preferred embodiment of the present invention configured as described above is coupled to the housing 600 and protrudes below with reference to the drawings.

In the state where the tray 500 protrudes from the housing 600, the ejection spring 625 of the ejection device 620 is in a state where a compressive force does not apply.

When the tray 500 is pushed into the housing 600 in the direction of the arrow, the pushing table 550 installed on the bottom thereof also moves toward the housing 600. Accordingly, the pushing stand 550 pushes the support part 624 of the take-out device 620 and 620 installed on the upper surface of the housing 600, so that the push-out spring supported by the support part 624 ( 625 is compressed until the tray 500 is fully inserted into the housing 600.

When the tray 500 is fully inserted into the housing 600, the locking jaw 540 provided on the bottom surface of the tray 500 is caught by the locking member 617 installed on the upper surface of the housing 600. do. Accordingly, the tray 500 and the housing 600 are coupled to each other, and the ejection spring 625 is compressed so that the ejection lever 621 is elastically biased in the direction in which the tray 500 protrudes.

When an eject signal is input to the solenoid 610 while the tray 500 is coupled to the housing 600, the iron core 613 slides into the stator 612. One end of the locking member 617 connected to 613 is also moved together so that the other end of the locking jaw 540 is released from the locking jaw 540. Meanwhile, in an emergency in which the solenoid 610 is not operated, the eject lever is pushed to the iron core 613 of the solenoid 610 by pushing an eject lever installed on the bottom of the tray 500, which is not shown in the drawing. The locking member 617 is pushed into the stator 612 to be released from the locking step 540 by the above-described action.

Then, the tray 500 is disengaged from the housing 600 and pushes the support part 624 while expanding by the restoring force stored in the ejection spring 625 in the compressed state and the support part 624. ) Also pushes the pushing stand 550 in contact. Therefore, the tray 500 protrudes from the housing 600.

Therefore, as shown in FIG. 4, the tray 500 protrudes from the housing 600.

6A is an enlarged side view of the take-out apparatus 620, and FIG. 6B is an enlarged plan view of the take-out apparatus 620. As shown in FIG.

Referring to FIG. 6A, the take-out spring 625 is installed to be in close contact with the housing 600, and the take-out lever 621 is installed to penetrate the take-out spring 625. The width W2 is smaller than the diameter D of the take-off spring 625. Therefore, the width W2 of the ejecting lever 621 according to the present invention is reduced rather than the width W1 of the ejecting lever 621 of the conventional ejection apparatus 620 shown in FIG. 3A, and the conventional ejection spring ( The height h1 provided with the 253 is reduced to the diameter D of the take-out spring 625 according to the present invention, thereby saving space by the difference.

In addition, referring to Figure 6b, the take-out spring 625 is installed spaced apart by the h3 from the edge of the housing 600, which is of the take-off lever 254 of the conventional take-out device 250 shown in Figure 3a This is because the width W1 is reduced to the width W2 of the takeout lever 621 according to the present invention. Therefore, the space can be saved by the difference. Therefore, the optical disk drive 400 can be made slim and compact.

As described above, the optical disc drive according to the present invention uses a compression spring as a take-out spring in the take-out device and installs the take-out lever through the take-out spring, so that the diameter corresponding to the diameter of the take-out spring is spaced apart from the tray. Since the width is smaller than the diameter of the take-out spring, the space spaced from the edge of the tray is reduced, which makes it possible to slim down and downsize the optical disk drive.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary and will be understood by those skilled in the art that various modifications and variations can be made therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
