The present invention relates to a compact disc changer, and more particularly, the reliability of the product is improved by eliminating the causes of damage and generation of static electricity of the compact disc transferred to the regeneration position of the reproducing apparatus by the operation of the ejecting plate. A compact disc conveying device of a compact disc changer which is intended to be improved.

In general, when the compact disk changer (Compact Disk Changer) accommodates a plurality of compact disks in the Disk Magazine (Bar Magazine), it is to take out any one of the compact disk to perform the playback function, The taken out compact disc is conveyed to a reproducing position of a reproducing apparatus having a scanner and a signal processing circuit in accordance with driving of the lift apparatus.

As shown in FIG. 1, the compact disc conveying apparatus of the conventional compact disc changer is provided with a guide plate 2 on one side of the lift 1, and an ejecting bar on the guide plate 2. (3) is elastically mounted to be movable by sliding.

Further, the ejection bar 4 is mounted at one end of the ejecting bar 3, and the ejecting bar 3 has a gear group 6 and a cam gear 7 in which rotational forces of the driving motor 5 are sequentially interlocked with each other. Is transferred by).

On the other hand, a pair of rollers (8a, 8b) are installed at a predetermined interval apart so as to be freely rotatable by the gear group (6), the surface of the roller (8a, 8b) so that the compact disc (CD) is in close contact and transported It is made of a rubber material, and the compact disc (CD) is stored in a plurality of disc magazine (not shown).

Therefore, the conventional compact disc transfer device is rotated while the drive group 5 is interlocked with each other sequentially by the drive of the drive motor 5, when the drive motor 5 is driven according to the user's mode setting, As a result, the ejecting bar 3 receives the rotational force of the cam gear 7 and slides on the guide plate 2 to move in the horizontal direction.

Then, as the ejecting bar 3 is moved, the ejecting piece 4 operates a lever (not shown) in the disc magazine to eject the compact disc CD to the outside, and the ejected compact disc CD is a roller. It is interposed between (8a, 8b). At this time, the roller (8a, 8b) is rotated by the gear group (6) to transfer the compact disc (CD) to the playback position of the playback device to perform the playback function of the compact disc (CD), which is the Since the static electricity is generated by the friction in the process in which the compact disc (CD) is taken out from the disc magazine, malfunction of the compact disc changer occurs.

In addition, as the compact disc CD is interposed between the rollers 8a and 8b, foreign matter such as dust or the like on the surface of the compact disc CD contaminates the rollers 8a and 8b. When the contamination of the (8a, 8b) is severe, there is a problem of lowering the reliability of the product, such as to further contaminate the compact disc (CD) more seriously to damage the surface.

On the other hand, the assembly structure of the components such as the roller (8a, 8b) is complicated to act as a factor to reduce the productivity, and at the same time occupy the installation space larger than necessary, causing problems in miniaturization of the product .

The present invention has been proposed to solve the conventional problems as described above, by removing the plate on which the compact disc is seated according to the slide movement of the ejecting plate from the disk magazine, the damage and static electricity generated by the conveyance of the compact disc The main cause of this is eliminated, the reliability of the product is improved, the composition of each component is simplified, the assembly process is easily improved, and the compact disc of the compact disc changer that makes the product small and manufactured by efficiently utilizing the installation space. The object is to provide a conveying device.

A feature of the present invention for achieving the above object is a compact disc changer configured to selectively take out any one of the compact discs housed in a disc magazine to perform a playback function, which is mounted on the side panel of the lift. An ejecting plate having a rack portion that is movable in a horizontal direction by a gear and having an operation pin coupled to the slide hole of the side panel so as to be guided; The compact disc transfer device of the compact disc changer is installed on one side of the ejecting plate to be provided with an elastic force of the spring, the holder is formed with a locker portion to be able to take out the plate on which the compact disc is seated from the disc magazine.

A more preferable feature of the compact disc conveying apparatus of such a compact disc changer is that a guide is formed on the side panel of the lift so that the ejecting plate is fitted and slides.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, one preferred embodiment of a compact disc transfer device of a compact disc changer according to the present invention will be described in detail with reference to the accompanying drawings. 2 to 4 are diagrams for explaining the compact disc conveying apparatus according to the present invention, the gear 12 is mounted on the side panel 11 of the lift 10, the gear 12 is not shown By the drive of the drive motor is not sequentially received the rotational force of the gear group rotated in conjunction.

A plurality of slide holes 13a and 13b extend in the same straight line at a predetermined position of the side panel 11, and one end of the side panel 11 extends the guide 14 in the longitudinal direction thereof. Is formed.

On the other hand, the lift 10 is a step (pitch) is stepped up and down by the slide plate 16 is transferred in the horizontal direction by receiving the driving force of the general drive device 15.

Reference numeral 20 denotes an ejecting plate, and the ejecting plate 20 is mounted to be slidably movable to the guide 14 of the side panel 11. The rack part 21 is formed on the upper part of the ejecting plate 20 so as to be engaged with the gear 12, and the operation pins 22a and 22b are coupled to one side of the ejecting plate 20 to slide the ball. It is fitted to 13a and 13b, respectively.

In addition, the fixing piece (23a, 23b) is bent away at a predetermined distance on one side of the ejecting plate 20, the fixing pin (24) is interposed between the fixing piece (23a, 23b), the fixing pin ( 24, the holder 30 is mounted to receive the elastic force of the spring 25.

In addition, the holder 30 has a locker portion 30a to take out the plate 32 on which the compact disc CD is mounted from the disc magazine 31, and the locker portion 30a is formed in a U shape. By the coupling relationship corresponding to each other and the locking groove (32a) of the plate 32 will be able to perform the extraction function of the plate (32).

Referring to the operation state of the compact disk transfer apparatus according to the present invention as described above are as follows.

First, when the driving device 15 is driven according to the user's mode setting, the slide plate 16 is horizontally moved by the driving force of the driving device 15 to move the lift 10 step by step by moving up and down step by step. It reaches a certain position.

On the other hand, the gear 12 mounted on the side panel 11 of the lift 10 is rotated by a gear group that is rotated in sequence by the drive of the drive motor, the gear 12 is meshed with each other The rotational force is transmitted to the rack portion 21 of the ejecting plate 20.

The ejecting plate 20 is slid in the horizontal direction on the guide 14 according to the guide of the operation pins 22a and 22b fitted to the slide holes 13a and 13b.
