The present invention is configured to mount and load the optical recording medium to be loaded to the recording medium to play selectively according to the user's choice by mounting the margin loaded with a plurality of optical recording medium in the medium, in particular the transfer of a plurality of trays The present invention relates to a plurality of optical record carrier auto changer players for automatically switching to a loading or unloading mode by a transfer member.

In general, an auto changer player equipped with a margin for loading a large number of optical recording media capable of playing a higher quality sound, such as a car audio system, and automatically selects and plays a song according to the driver's preference is put to practical use. There is a trend.

The structure of the auto changer player will be described with reference to the drawings contained in Korean Application No. 93-8742 as follows.

A play section (hereinafter referred to as a playback section) 10 for driving by installing a turntable 11 and a pickup assembly 12 on one side of the main chassis 1; A margin 20 installed at one side of the reproduction unit 10 to mount a tray (not shown) in which a plurality of optical recording media are embedded; A loading assembly (30) for loading the optical recording medium of the tray onto a turntable (11); It consists of operating means 40 for selectively operating this loading assay 30.

The loading assembly comprises a takeout means 60 for taking out the optical recording medium D loaded in the margin, and a loading means 50 for moving the loaded optical recording medium D to the turntable 11 for loading. The take-out means 60 is formed with a rack 62 engaged with the pinion 61 which is rotated by receiving the power of the motor M, and has a link plate 63 having a bent tension engaging portion at its tip. On the other hand, the loading means 50 guides the pair of feed rollers 51 rotated by the driving force of the motor M, and guides the optical recording medium D conveyed by the feed rollers 51. It consists of a guide 52.

Referring to the operation of the auto changer player configured as described above, if the tray with a plurality of optical recording medium is mounted in the margin, and the loading mode is given, while the motor of the power unit is driven, the loading assay 30 As the ascending order rises from the lowest position, the optical recording medium loaded in the margin is identified, and during the lowering operation, the selected optical recording medium is taken out, loaded into the turntable, and played.

However, the following problems are pointed out in the above auto changer player.

First, the auto changer is installed by dividing the main chassis image into roughly two portions and installing a tray holder equipped with a plurality of trays on one side, and a playing unit for playing the optical recording medium embedded in the margin when loading the other side. The size of the player has increased.

Secondly, a transport roller for transporting a tray and an optical recording medium, a loading assay for transporting the optical recording medium to a reproducing unit, and an up / down member for up and down to play the conveying unit to a fixed reproducing unit. There is a problem such as the complexity of the structure and the increase in production cost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above drawbacks, and is automatically switched to a loading or unloading mode by a tray conveying unit for conveying a plurality of trays, and at the same time, the reproducing unit is directly up / down and the optical recording medium is positioned at that position. It is possible to simplify and compact the configuration of the optical recording medium by enabling the transfer and reproduction of the optical recording medium.

FIG. 2 is a plan view briefly showing the optical recording medium autochanger player of the present invention, and FIG. 3 is an exploded perspective view showing a part of the present invention.

First, the present invention will be described with reference to FIGS. 2 and 3, and a regeneration unit 10 having a turntable 11 and a pickup unit 12 is provided on one side of the main chassis 1, and this regeneration unit ( A guide housing 100 for guiding 10); A first elevating device 200 for elevating the guide housing 100 itself; Drive means (400) for driving a plurality of trays (310) installed on one side of the guide housing (100); A second elevating device 500 for elevating and regenerating the regeneration unit 10 in association with the transfer of the tray 310; The technical configuration is given to the power transmission mode switching device 600 for controlling the loading mode of the tray driving means 400.

The mode switching device 600 includes a gear train G for transmitting power from the drive means 400 as shown in FIG. A train gear G1 formed in a part of the gear train G; A gear unit 311 formed at one end of the tray 310 which is engaged with the train gear G1 and transfers the optical recording medium D toward the reproduction unit 10; Mode switching to prevent the rotation of the tray gear G1 when the tray 310 is being loaded / unloaded and to allow the rotation of the tray gear G1 when the tray 310 is inserted into the margin 300. Member 610; First and second guide members 620 and 620 'for guiding movement of the mode switching member 610; It is composed of an elastic member 630 for returning the mode switching member 610 to its original state.

The mode switching member (610) and the rotating piece (640) for enabling the rotation by the pivot shaft (P) of the tray gear (G1) as a point; A locking projection 641 formed at the bottom of the pivoting piece 640; The first and second guide members 620 formed at predetermined intervals at the bottom of the guide housing 100 by the gear part 311 side of the tray 310 while temporarily stopping the locking protrusion 641. 620 'is composed of a conversion lever 650 actuated in response to the elastic force of the elastic member 630 (see Fig. 4).

The conversion lever 650 is formed with guide holes 651 and 651 for inserting the first and second guide members 620 and 620 'formed at the bottom of the guide housing 100. A catching piece 652 for catching one end of the elastic member 630 elastically engaged to the second guide member 620 'is bent downwardly.

The second elevating device 500 is a discontinuous gear that moves forward or backward along the guide holes 2 and 2 'formed on the main chassis 1 by the tray driving means 400 as shown in FIG. 510 and the guide inclined groove (10a) for inserting the guide pin 511 formed at one end of the discontinuous gear 510 is composed of a regeneration unit 10 formed on one side, the bottom surface of the discontinuous gear (510) Guide pins 512 and 512 ′ are formed to be inserted into the guide holes 2 and 2 ′ formed on the main chassis 1.

Next, the first elevating device 200 for elevating the entire guide housing 100 in which the regeneration unit 10 is installed is provided with guide plates 210 on both sides of the main chassis 1 as shown in FIG. 5. The guide plate 210 is formed to have a long guide hole 211 in a stepped shape, and guide pins 111 formed at both ends of the guide housing 100 are inserted into the guide hole 211 so that the guide plate ( It is configured to be stepped up and down by the operation of a driving means (not shown) engaged with the gear portion 212 formed at one end of the 210.

Therefore, the plurality of optical recording medium reproducing / lifting apparatus configured as described above is provided with the trays formed on the main chassis 1 by mounting the respective optical recording mediums D on the plurality of trays 310 stacked in the margin 300. When the optical recording medium loading mode is given to the mounting portion, the driving motor of a driving means (not shown) is operated, and the guide housing 100 in which the reproducing portion 10 is installed as shown in FIG. Stop at a desired position along the guide hole 211 of the guide plate 210 installed at both sides.

Next, the tray drive means 400 is operated, and the pinion gear 410 installed on the shaft of the drive means 400 is rotated, and the rotational force of the pinion gear 410 is the gear train of the mode switching device 600. (G) is delivered,

At this time, the tray 310 engaged with the tray gear G1 which is variably rotated when the pivot shaft P is loaded or unloaded as the support point of the gear train G moves toward the regeneration unit 10. When the conversion lever 650 is pushed in the direction of arrow A in FIG. 6A, the tray gear G1 also moves toward the regeneration unit 10 with the pivot shaft as a supporting point.

Next, as the clutch gear G2 and the driven gear G3 rotatably supporting the tray gear G1 rotate, the discontinuous gear 510 moves in the direction of arrow B of FIG. 6B.
