DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk reproducing apparatus which prevents a disk surface from being damaged when a disk is transported.

[0002]

2. Description of the Related Art FIG. 9 is a perspective view of a conventional disk reproducing apparatus. In FIG. 9, a disc reproducing device is detachably fixed to the main body 1, and includes a disc rack 3 in which a plurality of discs 4 n are arranged in a horizontal direction in a vertical position and stored in the front-rear direction of the main body 1. It is movable along the arrangement direction of the stored disks 4n, and is rotatable from a vertical position to a horizontal position in which the outer peripheral end of the disk 4n arbitrarily selected from the disk rack 3 is gripped and placed on the disk reproducing unit 9. The transport unit 5 includes a suitable disk loader 11.

In order to reproduce the selected disk, the transport unit 5 raises a lifter unit to take out the selected disk from the disk rack, and guides the raised disk with guide rollers extending from the transport unit to guide the disk. Moving to the loader. Also, the disc that has finished playing is
It is moved from the disk loader to the disk rack for storage in the original location of the disk rack. This disc reproducing apparatus is disclosed in Japanese Patent Application Laid-Open No. 8-167222.

[0004]

However, since the cross section of the contact portion of the lifter portion with which the disk comes into contact has a plane, a V-groove or a U-groove, the lifter portion is raised and selected. When the disk is moved from the disk rack to the transport unit, the disk is inclined and contacts the partition plate of the disk rack. Then, since the disk moves while being guided by the guide rollers while being inclined, there is a problem that the disk surface comes into contact with the partition plate and is rubbed, and in some cases, the disk surface is damaged.

When returning the disk from the transport unit to the disk rack, the disk moves while being guided by the guide rollers, and moves while contacting the partition plate of the disk rack. Therefore, the disk rubs against the partition plate of the disk rack. ,
In some cases, there is a problem that the disk surface is scratched. SUMMARY OF THE INVENTION It is an object of the present invention to provide a disk reproducing apparatus which does not damage the disk surface when the disk is moved.

[0006]

According to a first aspect of the present invention, there is provided a disk reproducing apparatus comprising: a disk rack for storing a plurality of disks arranged in a horizontal position in a vertical position; A disc reproducing device, comprising: a disc reproducing unit, and a conveying unit that can move along the arrangement direction of the disks housed in the disk rack and mounts a disk selected from the disk rack on the reproducing unit. A lifter portion extending from the transport portion so as to swing freely and pushing up the disk from the lower surface of the disk rack, and the lifter portion is provided with a holding portion for erecting the disk.

Accordingly, the disc pushed up by the lifter is held upright by the lifter, so that the disc can be moved to the disc loader without rubbing against the partition plate of the disc rack.

According to a second aspect of the present invention, in the disk reproducing apparatus according to the first aspect, the lifter unit raises the lifter unit when storing a disk in the disk rack. The disc is held by the holding portion and lowered to receive the disc in the disc rack.

Therefore, when the disc is stored in the disc rack from the transport section, the lifter section is lifted and the disc is clamped by the clamping section of the lifter section, so that the disc stands upright and the disc rubs against the partition plate of the disc rack. You can move without. Further, even if the disk is stored in the disk rack by descending the lifter portion, the disk can be stored without being rubbed by contacting the partition plate of the disk rack.

According to a third aspect of the present invention, there is provided a disk reproducing apparatus for storing a plurality of disks arranged in a horizontal direction in a vertical position, and a disk reproducing means for reproducing the disks. In a disc reproducing apparatus including a transport unit that can move along the arrangement direction of the disks stored in the disk rack and mounts a disk selected from the disk rack on the playback unit, the transport unit swings from the transport unit. A lifter portion movably extending and pushing up the disk from the lower surface of the disk rack,
The lifter is characterized by having an inclined portion on which the disk slides down and a concave portion connected to the inclined portion and holding the disk upright.

Therefore, when the lifter is raised, the disk placed on the disk rack slides down along the inclined surface of the lifter and is supported by the concave portion. The disc can be moved to the transport unit without rubbing the disc with the partition plate of the disc rack.

According to a fourth aspect of the present invention, in the disk reproducing apparatus according to the third aspect, the lifter raises the lifter when storing a disk in the disk rack. Then, the disc is placed in the recess and then lowered to accommodate the disc in the disc rack.

Therefore, when the lifter is raised, the disk is supported by the concave portion of the lifter, so that when the disk is moved from the transport unit to the disk rack, the disk does not contact and rub against the partition plate of the disk rack. Further, even if the lifter section is lowered and the disk is stored in the disk rack, the disk can be stored without coming into contact with and rubbing against the partition plate of the disk rack.
