As shown in the drawing, the deck part 3 is provided through the entrance 1a of the front of the case 1. Here, the deck portion 3 is moved forward and backward by a deck transfer means (not shown) and is configured such that its upper end is opened when it is exposed to the outside of the doorway 1a.

In addition, the deck portion 3 described above has a disk seating plate 5 formed integrally, and a plurality of seating parts 5a on which the disk 7 is seated is formed on an upper surface thereof.

The disk seating plate 5 described above is rotated by a motor 6 geared about its central portion. That is, the above-mentioned disk seating plate 5 is rotated by the rotation of the drive gear 6a fixed to the motor 6 by rotating the rotary gear 5b which is correspondingly fixed to the center of the disk seating plate 5. Will be rotated.

At the rear of the deck portion 3, head transfer means 4 including a head 4a is provided to reproduce the selected disc 7.

When the drive gear 6a is rotated as shown in FIG. 2 by the drive of the motor 6, the conventional disk chain storage device configured as described above rotates the rotary gear 5b in the other direction.

Therefore, the disk seat plate 5 fixed to the rotary gear 5b is rotated in the same direction with the rotary gear 5b, so that the position of the disk 7 seated on the seating portion 5a is changed to the head transfer means ( 4) It is moved to the top so that the selected disc 7 can be played.

However, such a conventional disk chain storage device has a problem in that the disk seating plate on which a plurality of disks are seated is formed in a circular shape so that the plane width thereof cannot be reduced, thereby increasing the volume of the disk seating plate and the entire case including the disk seating plate.

Accordingly, an object of the present invention for solving the above problems is to independently move each other by eccentric rotation of the seating plate on which a plurality of disks are seated independently, thereby increasing the speed according to the position movement and reducing the volume of the independent Disc chain storage having a rotating seat plate.

In order to achieve the above object, a disc changer device having an independent rotary seat plate according to the present invention is characterized in that a plurality of discs are provided so as to reproduce a selected disc by moving a position thereof. And a plurality of independent rotary seating plates that are seated and independently eccentrically rotated to move each other, and a rotation drive unit which rotates the independent rotary seating plates to a selected position, respectively.

In addition, the rotation driving unit is a drive gear rotated by a drive motor, a fixed gear formed to surround the drive gear, and the internal gear is inscribed in the fixed gear and the external drive gear is moved along the rotation direction, the independent on the top Preferably, the rotatable seating plate is composed of a plurality of rotary gears each of which is eccentrically fixed.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a disc changer device having an independent rotary seat plate according to the present invention will be described in detail.

Figure 3 is a schematic cross-sectional view showing a preferred embodiment of the disc changer device having an independent rotating seat plate according to the present invention, Figure 4 is a perspective plan view showing a rotating state of the disc changer device having an independent rotating seat plate according to the present invention to be.

As shown, the deck portion 31 is provided through the entrance 11 in front of the case 10, the deck portion 31 is moved back and forth by the deck transfer means (not shown). Therefore, when the deck portion 31 comes out of the doorway, its upper end is configured to open.

In addition, a plurality of independent rotary seating plates 30 are provided at the upper end of the deck part 31, and each disk 50 is seated at the upper end thereof, and when a predetermined disk 50 is selected, each of the eccentricities is independently eccentric. Rotation moves each other.

Accordingly, the head transfer means 20 including the head 21 moved forward and backward is provided at the rear of the deck part 31 to reproduce the selected disc 70.

In addition, the rotation drive unit 40 rotates the above-described independent rotary seat plate 30 to the selected position, respectively, so as to surround the drive gear 42 and the drive gear 42 rotated by the motor 41. A fixed gear 44 formed on the outside thereof is provided.

In addition, it is inscribed with the above-mentioned fixed gear 44 and moved outside the drive gear 42 in the rotational direction of the drive gear 42, the above-described independent rotary seat plate 30 is eccentric respectively. It is composed of a plurality of fixed rotary gear (43).

Referring to the operation of the present invention configured as described in more detail as follows.

First, the deck part 31 enters and exits through the doorway 11 of the front of the case 10, and when the deck part 31 comes out of the doorway by a deck transfer means (not shown), the upper part of the deck part 31 is opened. Thus, each disk 70 is inserted or removed on top of the plurality of independent rotating seating plates 30.

In addition, after the deck part 31 is inserted into the case 10, the independent rotating seating plates 30 on which the plurality of disks 70 are seated are independently eccentrically rotated to move each other, thereby selecting the selected disk. 70 is located above the head transport means 20. Thus, the selected disc 70 can be played back through the head 21.

Here, the above-described plurality of independent rotary seating plates 30 are rotated through the rotation driving unit 40 and moved to selected positions, which will be described in more detail with reference to FIG. 4 as follows.

First, when the drive gear 42 rotates in one direction by driving the motor 41, the plurality of rotary gears 43 provided on the outer circumferential surface thereof rotates in the opposite direction of the drive gear 42. At the same time, the plurality of rotary gears 43 are inscribed with the outer fixed gear 44 and move along the rotational direction of the drive gear 42.

Therefore, each independent rotary seat plate 30 fastened to the rotary gear 43 is rotated in the same direction as the rotary gear 43, thereby moving the position of the disk 70 seated here.

Therefore, by appropriately adjusting the contrast of the rotational speed according to the number of teeth of each of the gears 42, 43, 44, the movement speed is adjusted, thereby enabling the rapid movement of the selected disk 70.

On the other hand, the above-described plurality of independent rotating seat plate 30 is configured to be a surface friction at a corresponding length ratio, it is preferable to maintain a constant distance at all times.

That is, the above-described plurality of independent rotating seating plates 30 are divided into line segments each having an angle of 60 ° from the center of rotation, and each center thereof is eccentric with a predetermined distance ratio, wherein the lengths of the line segments are always a constant length. As a result, the surface is rubbed and rotated.

As described above, the disc chain storage device having the independent rotating seat plate according to the present invention is rotated independently of each other by moving the mounting plate on which the plurality of disks are seated, while maintaining a predetermined length ratio. There is an effect that can increase the speed and reduce its volume.
