The present invention relates to a compact disc player, and more particularly, to a loading device for lifting and lowering the card rich so that any disc among a plurality of compact discs mounted on the card rich can be loaded onto the turntable of the compact disc player. It is about.

Conventional loading devices for loading any diskette of a compact disc mounted on a card-rich onto a turntable of a compact disc player are disclosed in Utility Model Publication No. 90-7348 and shown in FIG. 2) On one side of the magazine housing (3) is fixed to support the card rich (20) in which a plurality of compact disks are stacked, a plurality of lead screws (4) vertically installed on the front surface of each of the lead screw At the lower portion of the le 4, a lift gear 4a meshed with the rack 6 provided to be moved forward and backward by the driving motor 5 is provided. The clamp holder chassis 8 is supported by the lifter 7 screwed to the lead screw 4, and the guide rod 7a is installed at the lifter 7 on one side thereof, thereby providing a guide of the carrier 9. 9a is slidably installed, and the carrier 9 is engaged with the transfer gear 9b driven by a drive gear (not shown) to draw in and take out a disc stacked on the card rich 20.

In the conventional compact disc player, the card-rich loading device 1 is configured such that the rack 6 is moved and the rack 4a is rotated as the drive motor 5 rotates. Is rotated, the clamper holder chassis 8 is raised or lowered by a predetermined height, and as the transfer gear 9b rotates, the carrier 9 moves forward or backward and is fixed to the magazine housing 3 of the deck. A disk is drawn in and out from the reach 20.

However, in the conventional card-rich loading device 1 of the compact disc player, the card-rich 20 is fixed to the magazine housing 3 on the deck, and the clamper holder chassis 8 of the turntable is provided with the rack 6 and the lead screw. While being moved up and down by (4), it is possible to draw in and take out a disk from the card rich 20, which has a problem that the structure is very complicated and vibration is applied to the deck.

The present invention has been devised to solve the above problems, and the card-rich loading of a compact disc player that can reduce the production cost as well as its structure is simple and mechanically stable by lifting up and down the card-rich mounted on the compact disc. The object is to provide a device.

In order to achieve the above object, the present invention provides a card-rich loading device for a multi-compact disc player, in which the turntable of the compact disc has a subchassi provided on one side thereof, which is located on one side of the subchassis and is predetermined by lifting means. It is characterized in that it is provided with a card rich holder which is lifted to a height and fixed to support a plurality of compact disks stacked stack.

Hereinafter, with reference to the accompanying drawings will be described in detail one preferred embodiment according to the present invention.

In the card-rich loading device 10 of the multi-compact disc player according to the present invention shown in FIG. 2 and FIG. 3, the drive device 40 of the compact disc is installed on one side of the subchassis 11, and on the adjacent side thereof. The card rich holder 12 into which the card rich 20 on which the compact disc is stacked is inserted is supported so as to be elevated by a lifting means. Here, the elevating means 30 is provided with a first gear 33 driven by the worm gear 31a of the drive motor 31 fixed to the bottom chassis (not shown) and the idle gear 32 engaged with. The first gear 33 is fitted with a plurality of second gears 35 for supporting and rotating the lead screws 34 respectively inserted into the plurality of through holes 11a formed in the subchassis 11. . Each lead screw 34 is screwed with the lifting member 37 supported by the support block 36 fixed to the guard holder 12, respectively. Meanwhile, although not shown in the drawing, the drive device 40 of the compact disc further includes a disk withdrawing means for drawing in and out from the card rich 20 which is lifted by the lifting means to the compact disc drive device 40. Reference numeral 36a is a lifting member support pin.

Referring to the operation of the card rich loading device of the multi-compact disc player configured as described above are as follows.

First, the card rich 20 in which the compact discs are stacked at predetermined intervals is mounted in the card rich holder 12 of the loading apparatus.

In this state, in order to load the desired compact disc among the compact discs loaded on the upper or lower portion of the card rich 20 on the turntable, first, the drive motor 31 is driven by a predetermined rotational speed and the worm gear installed on the rotating shaft. As 31a, the first gear 33 is rotated forward or reverse. When the first gear 33 rotates, each of the second gears 35 engaged with the second gear 35 rotates, and the lead screw 34 supported thereto rotates. Therefore, the elevating member 36, which is screwed with the lead screw 34 and is supported by the card rich holder 12, is lifted so that the card rich 20 supported by the card rich holder 12 is positioned at a predetermined position. do. When the card rich 20 is moved up and down at a predetermined position as described above, although not shown in the drawing, a desired compact disc is taken out and loaded on the turntable as a drawing means installed in the driving apparatus.

As described above, the card-rich loading device of the multi-compact disc player of the present invention can simplify the structure by raising and lowering the card rich by the elevating means, and can prevent the vibration from being applied to the deck, thereby improving the reliability of the product. There is an advantage to that.
