DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk storage tray used in a protective case for storing a disk such as a compact disk.

[0002]

2. Description of the Related Art Conventionally, a compact disc (hereinafter also referred to as a CD) is formed to have a diameter of 120 mm and a maximum diameter of a recording area of 116 mm according to the standard. The protective case 1 for accommodating a CD of this size and shape is generally made of plastic in a shape as shown in FIG. A disk storage tray (indicated by reference numerals 3 and 5 in FIGS. 5 and 6, respectively) is fitted in the protective case 1, and C
D is stored in this disk storage tray, and the protective case 1
Are closed and the packaging is carried out as required, and then sold at stores. For example, in the disk storage tray 3 as shown in FIG. 5, a range slightly larger than the CD to be stored is molded as the concave molded part 7, and the disk holding part 13 is raised at the center of the concave molded part 7. The CD is fixed in the disk storage tray 3 by pressing the center hole into the disk holding portion 13 and locking it.

The disk holding portion 13 is formed so as to gradually become thinner from the upper portion to the lower portion, and the outer diameter of the lower portion is substantially equal to the inner diameter of the center hole of the disk. Below the disk holding portion 13, a disk protection step portion 15 for directly contacting the non-recording area from the center hole of the disk to the inner edge of the recording area of the disk and protecting the recording area outside this range. Is formed. The disk protection step 15 is formed so as to be higher than the concave molding 7 of the disk storage tray 3 in a height range of 0.3 to 1 mm.

[0004] A user who purchases a CD stored in the disk storage tray 3 first receives a cover 1 of the protective case 1.
1 and press the disk holder 15 lightly with your thumb,
An index finger or other finger is placed in a predetermined notch 17 of the disc storage tray 3. When the finger on the side of the notch is hooked on the periphery of the disk and lifted, the disk comes off from the disk protection step portion 15. At the same time, the thumb is inserted into the center hole of the disk, a CD (not shown) is sandwiched between these fingers, and the disk is taken out (a storage case as shown in JP-A-6-336279 is most common). Is a typical form).

On the other hand, in the disk storage tray 5 without the disk holding part itself, as shown by reference numeral 5 in FIG. 6, the entire CD storage part is formed as a circular recess 9 and the rising surface 19 at the peripheral edge thereof is directed downward. It is formed so that the diameter slightly expands toward it. In the case of this type, the thumb is inserted into the center hole of the disk, and at the same time, another finger placed in the predetermined notch 21 is hung on the periphery of the CD and lifted up. (See Utility Model Registration No. 3011566 for an example of this type of disk storage tray.)

However, in the conventional disk storage tray as described above, the disk 23 is entirely embedded in the disk storage tray 3 as shown in FIG. When trying to take out, as described above, first, a predetermined notch (FIG. 5)
In this case, a finger must be put on the disc at a position (such as No. 15 in FIG. 6, and No. 19 in FIG. 6), so that the position for taking out the disc is limited to only such a position. In addition, when taking out the disk while holding the protective case in hand, the position of the protective case is limited due to the opening of the lid 11, so that the user is not allowed to be relatively busy when in a busy state or in a car. The removal is not smooth and is often felt inconveniently inconvenient. Pulling it out in an unreasonable manner may damage the disk, or in the worst case, deform the disk.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a disk storage tray which does not have a cutout portion for taking out a disk and can take out a disk from any position of the disk storage portion.

[0008]

According to the present invention, there is provided a disk storage tray which is used by being incorporated in a plastic protective case for a compact disk or the like, and has a bottom surface which is smaller than the outer edge of the disk. A disk storage tray formed as a convex molded part having a predetermined height is provided. In one embodiment, an annular convex molded portion is formed on the bottom surface in a range smaller than the outer edge of the disk, and the annular convex molded portion has an upper annular convex portion that contacts only the non-recording area of the outer edge of the disk. Have.

[0009]

By forming a convex molded part in the disk storage part, a finger can be put on the outer edge of the disk at an arbitrary position, and the disk can be taken out or rotated at an arbitrary position. It is also possible to take out while
Easier disk removal.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION In each of the embodiments described below, a CD is used as a disk, but other disks, such as a laser disk and a DVD, can be used in the same manner. First, a first embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a perspective view of a disk storage tray 10 as a first embodiment. The disk storage tray 10 has a tray peripheral edge 12 sized and fitted into the inside of a protective case, similar to the conventional type shown in FIG. 5, for example. A disc protection step 16 for directly contacting and supporting a non-recording area at the center of the disc at a disc number 14, and projecting upward from the disc protection step 16 so that the center hole 18 of the disc and a lightly elastic And a disk holding portion 20 having a leaf spring structure that engages and engages.

However, the disk protection step 16 and the disk holder 20 of the first embodiment are different from the conventional disk protection step 13 and the disk holder 15 shown in FIG. Unlike the portion 7, ie, being raised from the center position of the tray lowest portion, the disk storage tray 10 is further raised from the convex molded portion 22 raised to a predetermined height from the tray lowest portion. . As shown in FIG. 2, the convex molding 22 has a peripheral edge 24 positioned slightly inward of the receiving disk 14 so that it can be fingered sufficiently on the outer edge of the disk. And the disk holding unit 2
The height is raised such that a sufficient space for inserting a cover jacket or the like is secured between the upper end of the cover 0 and the inner surface of the cover of the protective case.

In a prototype manufactured using polypropylene as the material of the disk storage tray, the height of the disk protection step 16 is set to 0.5 to 0.6 mm, and the height of the convex molding 22 is increased.
The diameter of the peripheral edge 24 is 5 to 6 m larger than the diameter of the disc.
m is φ114 to 115 mm, and the height H (see FIG. 2) of the protruded molded portion 22 itself is 2.5 to 3.5 m.
m, so that it was confirmed that the conventional protective case can be used as it is when formed so that the height from the lowermost portion of the tray to the lower surface of the disk is 3 to 4 mm. A protective sheet such as a nonwoven fabric may be attached to the entire surface of the convex molded portion 22 to protect the recording area of the disc,
Further, as described in JP-A-6-336279, the material cost may be reduced by partially forming a hole in the convex molded portion 22.

FIG. 3 illustrates a disk storage tray 100 as a second embodiment of the present invention. In the second embodiment, the disk storage tray 100 has an annular convex molding 220 having a constant width. The peripheral edge portion 240 of the annular convex molded portion 220 is slightly inside the outer diameter of the CD 14 to be stored, for example, corresponding to the peripheral edge portion 24 of the convex molded portion 22 of the first embodiment. It has a diameter and the same height as the convex molded part 22 of the first embodiment, and each part inside and outside the annular convex molded part 220 is a tray minimum part 260. . Although the height of the disc holding unit 200 itself is the same as that of the first embodiment, the disc protection step 160 for protecting the recording area of the CD 14 to be stored is moved from the inner tray lowest part 260 to the first embodiment. It has been launched to be the same height as that at

As shown in an enlarged view in FIG. 8, it is desirable that the annular convex molding 220 is positioned so as to be in contact with the CD at a portion outside the recording area indicated by "R" of the CD 14 to be stored. When the CD is taken out, the index finger (middle finger) or the thumb is usually used to remove the CD.
3, the thumb or index finger (middle finger) of the same hand is hung on the outer peripheral edge of the CD 6, and the disk is lifted on the outer peripheral side to remove the CD 14 from the disk holding portion 13. This is because the outer peripheral edge of the disk on the side opposite to the side on which the finger is hung is slightly pressed against the annular convex molding 220. If the pressed area is the recording area, the disc will of course be adversely affected.

FIG. 3 shows a second embodiment of the annular convex molding 22.
As long as there is no problem in strength, 0 may be an aggregate of convex portions intermittent in an arc shape. According to the CD standard, the width "L" of the non-recording area on the outer peripheral edge of the disk is 2 mm.
The width of the annular convex molded portion 220 is 2 mm or less, and further, it is necessary to be 1 mm or less in consideration of the fact that the outer diameter of the annular convex portion is desirably equal to or less than the diameter of the disk,
Such strength may not be maintained. But,
In this case, as shown in FIG. 8, only the upper annular convex portion 280 in contact with the non-recording area x is formed with a width of 1 mm or less.
A sufficient strength can be maintained by providing a step in which only the upper predetermined range portion is 1 mm or less, such as making the portion below that width wider.

Both plastic and paper can be used as the material of the disc storage tray. In the case of plastic, it can be processed into a predetermined shape by pouring the plastic into a mold with a molding machine. In the case of paper, it is desirable to use a paper having a certain strength, for example, a thick paper of 1 to 2 mm, and to use press molding for processing.

The outer diameters of the convex molded portion 22 and the annular convex molded portion 220 of the disk storage tray are set to be smaller than the diameter of the disk by one in consideration of the ease with which a finger can be put on the outer peripheral edge of the disk.
It is preferable that the thickness is reduced to about 5 mm. Further, if the height of the convex molded portion 22 and the annular convex molded portion 220 is too high, the thickness of the entire case becomes thick, and if the thickness is too small, it becomes difficult to put a finger. The height from the bottom of the disc storage tray to the bottom of the disc is 2 to 6 m.
m is desirable.

[0018]

According to the present invention, there is provided a disk storage tray in which a notch is not provided for taking out a disk, and a disk can be taken out from any position of the disk storage.
