The present invention relates to a compact disc autochanger player which loads a plurality of compact discs in a margin and mounts the margins in a disc player so that a disc to be played can be automatically loaded onto a turntable according to a driver's selection. In particular, the disc is loaded with a loaded Margin, the Margin lock plate and the eject lever is interlocked with each other and at the same time the locking plate is released by the loading plate, such as a smooth interlocking arrangement and a simple configuration.

In a recent car audio system, when installing a compact disc player for using a compact disc (CD) capable of playing better sound, a plurality of compact discs are loaded and automatically selected and played according to the driver's taste. The auto changer player has been put to practical use.

The general structure of the autochanger player described above will be described with reference to FIG.

It constructs a margin for storing and loading a number of compact disks, and loads a number of compact disks according to the driver's taste.

When a lot of discs loaded with a plurality of discs are mounted on the margin mounting portion of the auto changer player, the disc 3 in the margin 2 is searched by the lifting and lowering operation unit 1, and a predetermined disc to be played ( The pair of take-out rollers 4a and 4b are rotated and taken out 3).

Here, the lifting and lowering operation unit 1 has a clamper 6 which closely holds the disk 3 when it is loaded on the turntable 5, and a clamper arm 7 and a margin that freely support the clamper 6. It consists of a support table 8 for holding the disc 3.

And the optical pickup (9) for reading the record recorded on the disk (3) and the turntable (5) rotated and rotated by the spindle motor in order to rotate and play the disk (3) at the position where the lifting and lowering operation unit (1) descends. ) Is equipped with a drive unit.

That is, when a margin containing a plurality of disks is mounted, the disks are searched by the disk transport mechanism, the selected disks are drawn out, loaded on the turntable of the playing section, and the playback operation is performed.

In such a disc changer, it is necessary to discharge the margin from the disc changer or the margin attachment part when replacing the margin.

For this reason, a margaret ejector or a device is installed, but in this type of device, a lever is added to the margin in the discharge direction, and a margin is inserted against a force such as a spring acting on the lever. It is common for the margin itself or the lever to lock.

Next, when the margin is discharged for the replacement of the margin, the lock is released by the solenoid operation during ejection operation.

As a result, the lever is extruded in the direction of the insertion hole by the spring force, and the lever is discharged by the lever.

In the above-mentioned prior art, the lever is added by the spring, and the margin is discharged using the force. However, the margin loaded on the disc changer is increasing in weight because a plurality of CDs (compact discs) and the like are stored therein. Therefore, in order to reliably discharge this, the elastic force of the spring which adds the said lever must be set quite strong.

Therefore, on the contrary, when the margin is inserted, the force of the spring becomes resistive, so much force is required when inserting the margin, which makes it difficult to handle it considerably. At present, this type of disc changer is generally installed so that the marginal insertion direction is substantially horizontal in the trunk room of a car, etc., but conventionally, this type of disc changer is installed so that the marginal insertion direction is approximately vertical in the interior of a car. It is expected to be installed.

In this case, since the discharge direction of the margin is directly above, the force of the spring that adds the margin in the discharge direction must be increased by using the above-described conventional margin ejection apparatus. Therefore, in this case, the resistance at the time of inserting the margin increases.

In order to solve the above problems, there is a patent application No. 89-9537, but also, as shown in Figure 2 of the accompanying drawings, a disk drive unit (12) adjacent to the margin mounting portion 11, the disk drive unit ( 13) is disposed, and the disk drive unit 13 is fixed to the marginal table 20 side by side on the bottom plate 14 surface.
