Description

Optical disc drive

The present invention relates to an optical disc drive capable of reproducing various optical media.

In general, an optical disk drive is a device for recording / reproducing information of a disk-type recording medium such as CD, CD-R, DVD, DVD-RAM / ROM, and magneto-optical disk. In particular, a DVD-ROM (Digital Versatile Disc-Read Only Memory) is a reproduction-only recording medium (hereinafter referred to as an optical disc) that reproduces a large amount of various recorded information such as audio, video, and data.

In the high-density optical recording / reproducing apparatus, most cartridges are used because recording operations requiring high recording power are much less stable than read operations due to the influence of fingerprints and scratches. Also in a DVD-RAM drive apparatus, a cartridge is used to protect a disk from scratches, fingerprints, and the like and to maintain stability during recording. The cartridge corresponding deck mechanism is provided inside the optical disc drive capable of playing such an optical disc.

The deck mechanism according to the prior art has a structure in which the rotary cam directly lifts the deck at the bottom of the deck. This, by fixing the plate spring member on the rear end of the deck to maintain the deck in a horizontal state, and serves as a reference point of rotation during the up and down flow.

However, since the rotary cam is directly lifted by the leaf spring member while the rotary cam is directly lifted by the damper-free structure as described above, there is a problem vulnerable to vibration, noise, and load.

The present invention has been made to solve the above problems, and an object thereof is to provide an optical disk drive capable of withstanding vibration, noise, and load.

The optical disk drive of the present invention for achieving the above object, the main chassis, the deck is installed rotatably with respect to the main chassis, and the cartridge installed on the main chassis so that the optical disk is adopted, the seat is mounted In the optical disk drive comprising a tray, a clamping bracket installed on the tray to support the cartridge, and damping means for suppressing the flow of the cartridge seated in the tray, the damping means, And a tension member installed in the tray to provide a pressing force upward from a lower side of the cartridge, and a cartridge spring provided below the clamping bracket to provide a pressing force downward from an upper side of the cartridge.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are schematic exploded perspective views of elements employed in the optical disk drive according to the present invention, and FIG. 3 is a rear view of the clamping bracket coupled to the tray top in FIG. 1.

Referring to the drawings, a tray 20 on which a cartridge 10 employing an optical disk is placed, a deck 30 for supporting the tray 20, and the tray 20 and a deck 30 are provided. A main chassis 40 to be installed and a clamping bracket 50 to be installed on the upper part of the main chassis 40 are included.

The tray 20 is coupled to a plurality of tension members 22 into which the springs 21 are fitted to one side of the tray 20, and to one side of the tray 20 so as to fix the cartridge 10. A plurality of cartridge holders 23 and a plurality of holder springs 24 which are installed in combination with the cartridge holders 23 and are formed to penetrate the protrusions 33 of the deck 30. Four through holes 25 are formed.

The tension member 22 includes a boss portion 22a into which the spring 21 is fitted, and a hook portion 22b inserted into the boss portion 22a and the first coupling hole 201 of the tray 20. Formed. Accordingly, the first coupling hole 201 has one opening through which the boss portion 22a is inserted to form a hinge axis, and another opening formed in the shape of a long hole so that the hook portion 22b can be inserted and rotated by a predetermined angle. It will be included.

In addition, a protrusion coupling portion 23a is formed at one side of the cartridge holder 23 to be fitted into the second coupling hole 202 of the tray 20, and a protrusion 23b formed at the left and right sides of the cartridge holder 23. ) And the holder spring 24 are inserted into the third coupling hole 203 formed in the tray 20.

The deck 30 is provided on the frame 31, a plurality of rotating bosses 32 provided on one side of the frame 31, the front end of the frame 31, the through hole of the tray 20 Although not shown in the drawings, a plurality of lifting bosses 34 are provided to allow a cam slider to be fitted thereto.

The cartridge 10 is for protecting the optical disk, and the coupling groove 11 is formed at one side of the cartridge 10 to fit the upper end of the protrusion member 33. In addition, the main chassis 40 is provided with a plurality of hooks 41, which may be coupled to the pivoting boss 32 of the deck 30 at left and right sides, respectively.

The clamping bracket 50 includes a cartridge spring 51 for pushing the cartridge 10, an open catridge lever 52 for opening and closing a cartridge cover (not shown), and a cartridge 10 A clamper 54 for supporting the optical disk is included.

The optical disc drive according to the present invention configured as described above operates as follows.

The cartridge 10 is seated on the tray 20 in a state where the tray 20 shown in FIG. 1 protrudes from the main chassis 40 shown in FIG. 2. At this time, the cartridge 10 is seated on the tray 20 while retracting the cartridge holder 23 to the rear of the tray 20. In addition, the latching jaw 231 is formed in the cartridge holder 23, thereby preventing the cartridge 10 from being separated upward of the tray 20, and by the tension member 22 installed in the tray 20. 10) is elastically biased upwards.

Next, the tray 20 is inserted into the main chassis 40 by a loading device (not shown) installed in the main chassis 40. In the process of inserting the tray 20, the upper surface of the cartridge 10 is elastically biased in the direction of the tray 20 while contacting the cartridge spring 51 installed in the clamping bracket 50.

After the tray 20 is completely inserted into the main chassis 40, the lifting boss 34 is forced upward by a lifting means installed on the deck 30 located at the bottom of the tray 20 on the main chassis 40. It is rotated to the tray 20 side with respect to the rotational boss 32. As the deck 30 is raised, a turntable (not shown) installed on the deck 30 can lift the optical disc installed in the cartridge 10 and cooperate with the clamper 54 provided in the clamping bracket 50 to rotate the optical disc. To be supported. At this time, the cartridge 10 is opened by the cartridge cover (not shown) by the open cartridge lever (52).

Then, the projection member 33 formed on the deck 30 penetrates the through hole 25 of the tray 20 to be inserted into the coupling groove 11 of the cartridge 10 so that the cartridge 10 may be inserted into the tray 20. It is pressed against the flow.

As described above, the optical disk driver according to the present invention is a damping means for suppressing the flow of the cartridge 10 to the tension member 22 and the clamping bracket 50 elastically biased toward the cartridge 10 in the tray 20. By installing the cartridge spring 51 elastically biased toward the cartridge 10 side, the cartridge 10 does not flow in a state in which the cartridge 10 is seated on the tray 20 so that shock or vibration are not transmitted to the optical disk.

In addition, the deck 30 is raised to form a projection member 33 to be fitted to the coupling groove 11 formed in the lower portion of the cartridge 10 in the deck 30 is provided in the lower portion of the tray 20, the clamper 54 When supporting the optical disk accommodated in the cartridge 10, the projection member 33 is to suppress the flow of the cartridge (10).

The optical disk drive according to the present invention as described above has damping means so that the cartridge containing the optical disk does not flow with respect to the tray, thereby suppressing the transmission of vibration or noise transmitted to the cartridge through the tray or the clamping bracket to the optical disk. Has the effect.
