DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk apparatus for selecting and reproducing / recording a desired disk from a disk magazine accommodating a plurality of disks, and more particularly to a disk apparatus in which the disk magazine is divided into upper and lower parts. The present invention relates to a disk device and a disk magazine used in the disk device, in which the components can be arranged close to each other by performing disk selection and recording / reproducing, thereby miniaturizing the entire device.

2. Description of the Related Art In recent years, disk devices using a disk as a medium, such as a CD player and an MD player, have become remarkably widespread. In particular, as an on-vehicle disk device, an auto-changer type device that selects and plays a desired disk from a disk magazine containing a plurality of disks has been developed. This autochanger type disk device is particularly convenient for in-vehicle use, since it is not necessary to insert and remove the disks one by one every time the disk to be reproduced is changed.

In a disk device using such a disk magazine, a disk reproducing unit is provided adjacent to the magazine storage unit. In many cases, a desired disk in a magazine is pulled out by a transport mechanism, transported to a disk playback unit, set, and then played back. However, with such a configuration, it is necessary to keep a certain distance between the adjacent disk reproducing unit and the magazine accommodating unit in order to secure a space for setting and reproducing a disk in the disk reproducing unit. is there. Therefore, the size of the entire disk device is increased, which is disadvantageous as an in-vehicle device whose mounting space is restricted.

For example, in the case of a recent in-vehicle acoustic device, the size of the opening on the vehicle side for accommodating it is DI
It has been standardized to 180 × 50 (mm) called N size or 180 × 100 (mm) called double DIN size. In addition, the depth dimension of the opening is currently only about 160 mm, so that the space for mounting the acoustic equipment of the vehicle is limited.

On the other hand, considering that the size of the compact disk is 120 mm in diameter, in the above-described disk device, 120 × 2 = 2 in the longest width direction.
Since a dimension of 40 (mm) or more is required, it can be seen that equipment cannot be stored in the opening located beside the driver's seat.

[0006] Under the circumstances described above, the conventional CD autochanger is stored in the trunk of the vehicle or near the foot of the driver's seat. However, in the former case, there are drawbacks such as a narrow trunk space, the need to open the trunk every time a disk is replaced, and the necessity of a long line connecting the trunk and the operation unit. In the latter case, the space at the foot may be so narrow that the foot may be damaged if touched by mistake.

To cope with this, Japanese Patent Laid-Open Publication No. Hei 6-203
As proposed in Japanese Patent Application No. 519, a disk device that divides a disk magazine into upper and lower parts and reproduces a disk in a state in which a disk reproducing unit is transferred between the two is proposed.
