Description

Optical pickup transfer device {OPTICAL PICK UP TRANSFER DEVICE}

The present invention relates to an optical pickup of a disc player, and more particularly, to a pickup transport apparatus configured to stably transport an optical pickup for optically accessing an optical recording medium.

In general, a disc player mounts an optical pickup to an optical pickup conveying apparatus and irradiates light onto the recording surface of the disk while transporting it in the radial direction of the disk, and receives the light reflected therefrom to record information on the disk or to reproduce information on the disk. . Therefore, the optical pickup transfer device requires precise control so that the optical pickup follows the correct track position.

1 is a perspective view schematically showing a conventional optical pickup transport apparatus.

As shown, the optical pickup transfer device is installed on the base 1 to linearly transfer the optical pickup 2 in the radial direction of a disc (not shown). To this end, a pair of guide shafts (3) and (4) are installed on the base (1), and the guide support (2a) is coupled to the optical pickup (2) to be slidable along the guide shaft (3) (4). . One side of the optical pickup (2) is provided with a rack gear portion (5) having gear teeth (5a), the rack gear driving portion 6 is coupled to the rack gear portion (5) along the guide graft (4) It is slidably moved.

In the conventional optical pickup transport apparatus configured as described above, the rack gear driving unit 6 for converting the rotational motion of the drive motor into linear motion is driven so that the optical pickup 2 can enter the inner circumferential direction of the disk.

However, due to the coupling tolerance between the guide support 2a of the optical pickup 2 and the guide shafts 3 and 4, flow is generated when the optical pickup 2 moves. This has a problem that an error may occur in the optical pickup (2) that acts very sensitively.

The present invention has been made in order to solve the above-described drawbacks, and to provide the optical pickup transport apparatus to ensure that the transfer of the optical pickup is made stable by transferring the transfer of the optical pickup along the interlocking guide rails. For that purpose.

The present invention for achieving the above object, in the optical pickup transport apparatus for linearly moving the optical pickup on the base, a plurality of guide rails and bent on the base and bent to move the optical pickup, respectively, engaged with the guide rail Provided is an optical pickup transfer apparatus including a plurality of guiders installed at both ends of the optical pickup to be transferred.

The above object and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

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

2 is an exploded perspective view of the optical pickup transfer apparatus according to the present invention, Figure 3 is a perspective view of the optical pickup transfer apparatus according to the present invention.

As shown in FIG. 2, a plurality of guide rails are installed on the base 10, and a plurality of guiders moving in engagement with the guide rails are installed in the optical pickup 20.

In the plurality of guiders, the first guider 30 is formed on one side of the optical pickup 20, and the second and third guiders 31 and 32 are formed on the other side thereof.

Each guider 30, 31, 32 forms an "C" shaped opening groove 30a, 31a, 32a which is opened inward, and the opening of the opening grooves 30a, 31a, 32a. The directions may be different from each other.

The second guider 31 is opened such that the opening groove 31a faces downward, while the opening guide 32a of the third guider 32 opens toward one side.

In addition, a rack gear unit 50 having gear teeth 51 integrally connected with the optical pickup 20 is formed below the second and third guiders 31 and 32 to be coupled to the rack gear driving unit 60. .

In addition, first, second, and third guide rails 40, 41, 42 are formed on the base 10 so that each guider 30, 31, 32 may be coupled and transported.

The first guider 30 is engaged with the first guide rail 40 in correspondence with each other. Thus, the second guider 31 is connected to the second guide rail 41, and the third guider 32 is the third guide rail 42. ) Is moved by bite.

The guide rails 40, 41, and 42 may be integrally bent from the base 1 or may be separately formed rails.

Referring to the operation of the optical pickup transport apparatus according to the present invention configured as described above are as follows.

Referring to FIG. 3, the opening groove 30a of the first guider 30 is engaged with the first guide rail 40, and the opening groove 31a of the second guider 31 is the second guide rail 41. The opening grooves 32a of the third guider 32 are respectively coupled to the third guide rails 42.

In this state, as the rack gear unit 50 is driven by the drive of the rack gear driving unit 60, each of the first, second and third guides 30, 31, and 32 of the optical pickup 20 is moved to the first, second, and third positions. 2, 3 guide rails 40, 41, 42 will be transported along

In this way, each guider and the guide rail are interlocked with each other, thereby achieving stable transport without flow.

As described above, the above description merely illustrates a preferred embodiment of the present invention, and those skilled in the art should recognize that the present invention can be modified and changed without changing the gist of the present invention.

As described above, the optical pickup transfer apparatus according to the present invention has the effect that the transfer of the optical pickup is stable by transferring the transfer of the optical pickup along the guide rails engaged with each other.
