Description

DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a recording medium exchange device.
Recording media playback device, especially during playback
The present invention relates to a recording medium reproducing apparatus capable of exchanging media. [0002] 2. Description of the Related Art Conventionally, a recording medium having a recording medium exchange device is provided.
As shown in FIG. 11, a disc is inserted as a body reproducing device.
The inserted magazine is loaded into the device from outside and the magazine
The disc player that selects and plays the disc in the
there were. In such a disk reproducing device, a magazine
Remove the magazine from the device when replacing
To replace the disc, but replace the disc that was in the magazine.
When the disc is playing, the place where the disc being played was
If you insert another disc into the
When returning to the gin, there is a
Prohibit taking out magazines during playback.
The disk in the magazine cannot be replaced.
Was. [0004] Also, since an expensive magazine is required,
There is a problem that the cost of the entire apparatus is increased. Further
When replacing only one disk in the device,
Gin has to be removed and the disk replacement operation is troublesome.
There was a problem that. [0005] Disc playback with disc changer
Japanese Patent Application Laid-Open No. 4-3 / 2004 discloses that the apparatus does not use a magazine.
FIG. 1 shows an example of a disk reproducing apparatus disclosed in JP-A-8673.
It is shown in FIG. The stocker shown in the figure is a
Contains a number of carriers and any carrier
To the stocker moving means to match the height that is drawn out
More up and down. The tray is shown in FIGS. 12 (a) and 12 (b).
Between the load position and the eject position shown in FIG.
Be moved. As shown in FIG.
The carrier on which the load is placed is pulled on the tray at the loading position.
And, as shown in FIG.
Playback is performed by clamping the disc. FIG. 12A shows a tray on which a carrier is placed.
When moving from the state shown in FIG. 12 to the position shown in FIG.
The carrier on the tray is exposed outside the housing,
Replace disk or use new disk in carrier
Can be placed. Fig. 1 shows the tray on which the carrier is placed.
Move from the state shown in FIG. 2 (c) to the position shown in FIG. 12 (a)
And the carrier on the tray is returned to the stocker.
This makes it possible to swap disks or insert disks into devices.
Entry is performed. However, this type of disk reproducing apparatus
In this case, the transport means that transports the carrier in one direction
The disc is transferred to the playback position or outside. And di
The carrier on which the disc is placed passes from the stocker to the playback position
During playback of the disc.
There was a problem that exchange was not possible. [0009] On the other hand, during playback of the disc, the user must replay the disc.
We often think of discs that will be
If there is no disc in the unit, change the disc during playback.
Or there was a strong demand to add more disks. [0010] SUMMARY OF THE INVENTION The present invention has the above-mentioned points.
Was made in view of
Can be used during playback without using the magazine.
Recording media that can be replaced or additional recording media
A playback device is provided. [0011] SUMMARY OF THE INVENTION Reproduction of a recording medium according to the present invention
The apparatus includes a stocker capable of storing a recording medium and a recording medium.
Reproducing means for reproducing, a recording medium in the stocker and a housing
A first transfer means for transferring between the outside and the recording medium;
A second transfer between the stocker and the regenerating means.
Transfer means, the stocker and the first transfer means, and
Position relative to the second transfer meansThe above
Raise and lower the stockerPositioning means, said first transfer hand
A first motor for driving the stage and the second transfer means;
And a second motor that moves.
Therefore, when the recording medium is transferred to the reproducing means,
To move the positioning means, and move to the reproducing means.
A recording medium different from the transmitted recording medium is transferred to the first transporter.
Step allows transfer between the inside of the stocker and the outside of the housing
It is composed. [0012] According to the recording medium reproducing apparatus of the present invention, the first and second recording media reproducing apparatuses are provided.
And the second motor drive the first and second transfer means, respectively.
Recording media that can be exchanged during playback
A playback device can be provided. [0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A disk reproducing apparatus according to an embodiment of the present invention will be described.
