Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an automatic performance device for POM audio discs, and particularly to a small autochanger that can accommodate a large number of discs and has a simple disc transport mechanism. This article relates to five suitable disc storage boxes.

[Background of the invention]

Conventional automatic disc playing devices include Siegbox,
There were magnetic disk back drives, but all of them had drawbacks such as being unable to accommodate a small number of disks or being large.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a disc storage box that can accommodate Pfffi digital audio optical discs, and allows easy loading and unloading of discs, as well as easy loading of discs into a player using the same in an automatic performance device.

[Summary of the invention]

Although the object of the present invention is a disc storage box that is used against an automatic performance device, it can also be used for a simple disc storage box. Digitano ν audio discs have nL2 recording on one side and are easily damaged. The pond and river are on the label side. In the present invention, f number of drawers are provided to accommodate each disc. Insert the disc so that the recording side of the disc is on the open side of the drawer.

The first point of the present invention is that when the drawer is pushed in, the ramyl surface of the disk is automatically pressed against the bottom plate of the drawer, leaving a gap on the recording surface side.

By doing this, especially when the drawer is used with the drawer upright, it is possible to prevent the recording surface of the disc inside the drawer from hitting the bottom plate of the adjacent drawer or the pond and sustaining damage when the drawer is put in or taken out. be.

The 20th point of the present invention is that an opening is provided in the bottom plate of the drawer. With such a structure, the disc can be pushed out from the outside of the paper board of the drawer through the opening, and the disc can be easily loaded into the player device installed on the opposite side.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a conceptual diagram of an automatic performance device necessary for explaining the present invention in detail. 1 is a storage box that stores a large number of discs. In order to take out the storage box 1 and the disc 2 and mount them on the player device 3, a disc transport device 4 is required.

4, as shown by arrow 5, first take out the disk 2 from the storage box 1. Next, the disc 2 is conveyed in the direction of arrow 6 to the player device 3, and the disc 2 is engaged with the spindle 7. 8 is H for self-recording or playback.

The requirement for the storage box in FIG. 1 is that as many discs as possible can be stored in the storage box 1. If you try to increase the number of discs stored, the gap between adjacent discs will become narrower, making it easier for the disc surface to come into contact with the partition wall or curve of the storage box when inserting or removing a disc. Particularly with optical discs, the recording surface is easily damaged, so extreme care must be taken. In this way, the number of stored discs and the maintenance of the disc surface are generally contradictory requirements.

FIG. 2 shows an embodiment of the present invention that satisfies the first requirement described above. In FIG. 2, a drawer 9 is fitted into the disc storage box 1. As shown in FIG. In reality, a large number of drawers are fitted into one, but only one drawer is shown in FIG. 2 for ease of viewing the drawing. A disc 2 is housed in the drawer 9. 1 is provided with a guide 10 for guiding the drawer 9.

FIG. 3 is a sectional view of FIG. 2. The periphery of the disk 20 is pushed by the inclined portion of the guide 10 and moved toward the bottom plate of the drawer 9. If a storage space and a drawer having such a structure are used, the disk will always be moved to the left side in FIG. 3, so that it will not come into contact with the folding drawer 7 when it is inserted. Therefore, if the left side is used as a label surface and the right side is used as a recording surface, it is possible to prevent the recording surface from coming into contact with the company drawer 9' and being damaged when the drawer is put in or taken out. It also makes it easier to put discs in and take them out of the drawer. Also, from a manufacturing technology perspective, is there any warpage that occurs during or after molding of the disc 2, drawers 9 and 91, etc.? Even considering this recording surface (right side) and 9'
The gap between the recording surface and the recording surface can sufficiently prevent contact between the recording surface and the recording surface. The thickness of the digital audio optical disc is 1.2rj, and the thickness of the bottom plate of the drawer is 1.2rj.
A disc storage box can be designed by taking into consideration the width of the corner and 1 inch for each disc.
This value of 3.7 to 4.2 mm is extremely thin, considering that the thickness of the disk is 11 mm, and the thickness of the compact floppy disk cartridge is 5 mm.

The width of a typical home stereo system is about 460 yen, so if you use this width to arrange the disc storage case of M and Akira, you will be able to store about 100 discs. This makes it possible to create an automatic performance device that is small and can accommodate a large number of discs.

Furthermore, according to the present invention shown in FIG. 2, it becomes easy to take out the disk 2 from the drawer and mount it on the conveying device 4.

That is, since the right side 11111 of the drawer 90 is open, the disk 2 can be easily moved to the right by pushing it from the opposite side. For this purpose, an opening 11 is provided in the bottom plate of the drawer 9.

Through the opening 11, the disk 2 is pushed out toward the transport device that is coming to pick it up.

In the present invention, the shape of the guide 10 only needs to have the effect of hitting the periphery of the disk and pushing it in one direction (toward the bottom of the drawer); for example, the shape of the guide 10 is not a linear slope as shown in FIG. , may be rounded and box-shaped.

Further, the effects of the present invention are not lost even if the shape of the opening 11 in the drawer bottom plate is not similarly limited.

In addition, in FIGS. 2 and 3, the present invention has been described in detail under the condition that the disc is stored in the drawer so that the recording surface of the disc is on the opening side of the drawer, but the method of inserting the disc is It has no direct relation to the present invention.

For example, even if the disk has recording surfaces on both sides, when the drawer 9 is pulled out, the recording surface on the bottom plate side of the drawer moves together with the drawer, so there is no sliding between them, making it less susceptible to damage. On the other hand, if the recording surface on the opening side of the drawer comes into contact with the adjacent drawer 9, it will be subjected to large sliding movements and the recording surface will be lost. The present invention
You can prevent many types of situations.

Next, take out and put in the stored drawer? The second feature of the present invention will be explained. When putting in and taking out a drawer, a handle is generally provided, and the handle is grasped and moved back and forth.In order to embody this kind of action with an automatic performance device, etc., each drawer is provided with a part corresponding to the handle,
Next, a clasp, a chin support, etc. for grasping and releasing the grip are required, making the device complicated. FIG. 4 is an oil embodiment of the present invention, showing a side cross-section 1 of a disk storage box.

A cutout 11 is provided at the bottom of the drawer 9, and a bottle 12 is placed in the cutout 11.

By moving the bin 12 in the direction of the arrow 15, the drawer 9 can be taken in and taken out, making the above-mentioned storage unit unnecessary.

FIG. 5 is a three-dimensional view of the fang 4. The incision 11 is cut along the front surface of the storage box. Therefore, bin 12 is 1
It can be inserted from the side.

FIG. 6 shows a case where the dovetail 712 is provided along the bottom surface of the storage box, and operates in the same manner as in FIG. 4.

Generally, when pulling out the drawer 9, the guide groove is used to guide the drawer. Since this guide groove is normally provided along the upper and lower surfaces of the drawer 9, the method shown in FIG.
There is a dent where the bottom guide groove hits the bottom guide groove. In Figure 4, such concerns do not arise.

〔Effect of the invention〕

According to the present invention, a large number of discs can be stored in a disc storage box using a drawer, and a gap between the recording surface of a disc therein and an adjacent drawer can be automatically created, so that the drawer can be taken in and out. In this case, damage to the disk recording surface due to contact can be prevented, and disks can be easily taken in and out of the drawn drawer.
