As shown in FIG. 1, the lower case 1 has a quadrangular planar shape, has a bottom surface portion 4, a front wall 5, a rear wall 6, and left and right side walls 7, and a through hole 8 is opened near the rear wall 6 of the side wall 7. ing.
[0031]
As shown in FIG. 2, the lid member 3 has a quadrangular planar shape, and a plurality of support protrusions 10 for supporting the library are provided inside the left and right side walls 9, and the rear end of the side wall 9 is formed from the upper surface portion 11 of the lid member 3. Is also formed slightly longer and has a pin 12 protruding inward.
[0032]
The tray 2 also has a square planar shape, has a bottom surface portion 13, a front wall 14, a rear wall 15, and left and right side walls 16, and a through hole 17 is formed near the rear wall 15 of the side wall 16. A disk storage space portion 18 is formed by the bottom surface portion 13, the front wall 14, the rear wall 15, and the left and right side walls 16.
[0033]
A cylindrical portion 19 having a cylindrical shape is provided integrally with the bottom portion 13 from the bottom portion 13 so that the outer diameter of the cylindrical portion 19 is substantially the same as the inner diameter of the central hole of the optical disk 20 to be stored. Alternatively, the optical disc 20 is designed to be slightly smaller in diameter so that the optical disc 20 can be easily inserted into and removed from the cylindrical portion 19.
[0034]
A predetermined number of optical disks 20 (for example, 20 sheets) can be stored in the tray 2 (disk storage space 18), and the height of the cylindrical portion 19 is designed to be slightly higher than the total thickness of the predetermined number of optical disks 20 stacked. Yes. An insertion port 21 and a substantially moon-shaped locking piece 22 adjacent to the insertion port 21 are provided at the top of the cylindrical portion 19, and the locking portion is configured by both.
[0035]
As shown in FIG. 4, two substantially U-shaped cut grooves 23a and 23b extending from the rear wall 15 toward the cylindrical portion 19 side of the bottom surface portion 13 are provided at a predetermined interval. A lock piece 24 having a substantially U-shaped planar shape is formed between the letter-shaped cut grooves 23a and 23b. As shown in FIG. 3, the lock piece 24 is integrally connected to the upper portion of the rear wall 15 via the thin first hinge parts 25, 25 and extends from the first hinge parts 25, 25. 26 and 26, and a disc pressing portion 28 that is integrally connected to the distal end portions of the rotating piece portions 26 and 26 via thin second hinge portions 27 and 27.
[0036]
An opening portion 29 having a substantially half-moon shape is formed at a substantially central position on the free end side of the lock portion piece 24 (disk holding portion 28), and the opening portion 29 is designed to be slightly larger than the locking piece 22. A protruding piece 30 is formed on the inner side of the opening 29 so as to be one step lower and protrude toward the rear wall 15 (see FIG. 5).
[0037]
Between the opening 29 and the free end portion of the disc pressing portion 28, a convex portion 31 having a substantially half-moon-like planar shape is integrally formed. The convex portion 31 protrudes upward from the disc pressing portion 28 and is substantially concentric with the step portion 32 provided on the base side of the cylindrical portion 19 as shown in FIGS. Have the same height.
[0038]
The step portion 32 is provided so as not to damage the recording area of the optical disk 20 loaded in the tray 2. That is, as shown in FIG. 6, a doughnut-shaped non-recording area 34 is formed between the central hole of the optical disk 20 into which the cylindrical portion 19 is inserted and the recording area 33 on the outer periphery. On the other hand, the step portion 32 of the tray 2 is one step higher than the bottom surface portion 13, and the non-recording area 34 of the optical disc 20 is placed on the step portion 32, so that the recording area 33 becomes the bottom surface portion 13 of the tray 2. Therefore, the recording area 33 is prevented from being scratched.
[0039]
As described above, if the convex portion 31 having substantially the same height as the step portion 32 is provided at the free end portion of the lock portion piece 24, the lock portion piece 24 is caused by its own elastic force or the like so that the bottom surface portion of the tray 2 is provided. Even if it is lifted from 13, it is pushed downward by loading the optical disk 20 in the tray 2, and the lock piece 24 can be placed in a predetermined position as shown in FIG. Since the convex portion 31 is provided substantially concentrically with the step portion 32, the convex portion 31 contacts the non-recording area 34 of the optical disc 20, and the recording area 33 of the optical disc 20 is not damaged by the convex portion 31.
[0040]
As shown in FIGS. 3 and 4, a notch 35 for facilitating removal of the lock piece 24 is formed inside the free end of the lock piece 24 (on the rear wall 15 side). Further, in the vicinity of a corner portion where the front wall 14 and the side wall 16 are joined, concave portions 36 and 36 for facilitating the removal of the optical disk 20 from the tray 2 are provided. These notches 35 and recesses 36 are sufficiently wide to allow insertion of fingertips.
[0041]
As shown in FIG. 4, the intermediate portion 37 of the side wall 16 of the tray 2 is inevitably thin because the outer peripheral portion of the optical disk 20 approaches, but both side portions 38 on both sides of the intermediate portion 37 are covered with the lid member 3. It is thick due to the fitting. FIG. 12 is an enlarged cross-sectional view taken along the line YY of FIG. As shown in the figure, both side portions 38 are stepped due to the fitting with the lid member 3, and the lower half of the side portions 38 must be thick. However, if both side portions 38 are made thick as they are, deformation occurs due to resin sink at the time of molding, resulting in molding failure, and the lower case 1 cannot be reliably fitted.
[0042]
In order to avoid this problem, as shown in FIGS. 3, 5, and 12, a plurality of groove-like recesses 39 are formed on the outer surfaces of the side portions 38. In the present embodiment, the recess 39 extends in the horizontal direction, but a number of recesses that extend vertically or obliquely, or that are not groove-shaped but are independent of each other may be formed.
[0043]
The lower portion of the tray 2 is fitted inside the lower case 1, and both are detachably connected by engagement of a through hole and a pin or a concave portion and a convex portion. Then, the lid member 3 is rotatably supported by the tray 2 by inserting the pin 12 of the lid member 3 into the through hole 17 of the tray 2.
[0044]
FIG. 7 shows a state in which the lock piece 24 is placed on the bottom surface 13 side of the tray 2 and the lid member 3 is opened. In this state, the rotating piece portion 25 of the lock piece 24 is substantially vertical, and the disc pressing portion 28 is accommodated so as to be substantially flush with the bottom surface portion 13.
[0045]
FIG. 8 shows a state where a predetermined number of optical disks 20 are stored in the disk storage space 18 of the tray 2. When the optical disc 20 is stored, the rotating piece portion 25 and the disc pressing portion 28 are raised to a substantially vertical state while the free end portion of the lock piece 24 is taken out from the bottom surface portion 13 of the tray 2. Then, the cylindrical portion 19 of the tray 2 is sequentially inserted into the center hole of the optical disc 20 to load and store a predetermined number of optical discs 20 in the disc storage space portion 18.
[0046]
Next, the rotating piece 25 of the lock piece 24 and the disc pressing portion 28 are tilted almost horizontally to cover the upper surface of the optical disc 20, and the protruding piece 30 of the lock piece 24 is inserted from the insertion port 21 of the cylindrical portion 19. Then, it is immersed under the locking piece 22 of the cylindrical portion 19 and engaged with the locking piece 22. FIG. 8 shows the state of engagement between the cylindrical portion 19 and the lock piece 24.
[0047]
FIG. 9 shows a state in which the optical disc 20 is loaded and stored in the disc storage space 18 from above the lock piece 24 in the bottom portion 13. At that time, as shown in FIG. 10, the outer peripheral portion of the lowermost optical disc 20 is in contact with the lower portion of the rotating piece portion 26 and presses the rotating piece portion 26 in the arrow direction (1) with the first hinge portion 25 as a fulcrum. .
[0048]
When the rotary piece portion 26 is inclined as shown by a broken line and the lock piece 24 is not in a predetermined position on the bottom surface portion 13 of the tray 2, a part of the disc pressing portion 28 overlaps the bottom surface portion 13. . When the optical disk 20 is stored in this superposed state, the recording area 33 of the optical disk 20 may come into contact with a part of the disk pressing portion 28 and be damaged. In addition, when in a superposed state, there may be a case where a predetermined number of optical disks 20 cannot be accommodated in dimension.
[0049]
In order to avoid this, as described above, when the optical disc 20 is loaded in the disc storage space portion 18, the outer peripheral portion (the non-recording area portion) of the lowermost optical disc 20 comes into contact with the lower portion of the rotating piece portion 26. Thus, if the position of the lock piece 24 is set, even if the turning piece portion 26 is inclined, the turning piece portion 26 is pressed in the arrow direction (1) by the optical disc 20, and accordingly. The disc pressing portion 28 moves in the arrow direction {circle around (2)}, and the lock piece 24 automatically fits in a predetermined position on the bottom surface portion 13.
[0050]
FIG. 11 shows a state in which the lid member 3 is closed. The upper surface of the tray 2 is completely covered with the lid member 3 so that the optical disk 20 stored in the tray 2 is protected.
[0051]
Although not shown, the lid member 3 can be opened approximately 90 degrees and the optical disk 20 can be stored in a vertically placed state, and the optical disk 20 can be tilted forward by the engagement of the cylindrical portion 19 and the lock piece 24. There is nothing, and the vertical position is maintained. When using the optical disc 20, the lock piece 24 may be removed from the tubular portion 19, the desired optical disc 20 may be taken out, and the lock piece 24 may be engaged with the tubular portion 19 again.
[0052]
8 and FIG. 9, the disc storage container accommodates one optical disc 20 by removing the tray 2 from the lower case 1 and rotatably supporting the lid member 3 on the lower case 1. It can also be used as
[0053]
FIG. 13 is a diagram showing an engaged state of the lower case 1, the tray 2, and the lid member 3, and the tray 2 is not cross-sectional because the figure becomes complicated. As described above, the lower portion of the tray 2 is fitted to the lower case 1 and the lid member 3 is rotatably attached to the tray 2 to constitute a disk storage container.
[0054]
FIG. 14 is an enlarged cross-sectional view of the optical disk 20 stored in the disk storage container. For example, a tracking pregroove is formed concentrically or spirally on one side of a transparent substrate 41 made of a resin material such as polycarbonate resin or polymethyl methacrylate resin. On the transparent substrate 41, a recording layer 42 made of an organic dye such as a cyanine dye, an azo dye, a quinone dye, or an indigo dye is provided.
[0055]
A light reflecting layer 43 made of, for example, gold, silver, copper, aluminum or the like is formed on the recording layer 42, and further, a protection made of, for example, an ultraviolet curable resin, an epoxy resin, an acrylic resin, a silicone resin, or a urethane resin. A layer 44 is provided.
[0056]
When the optical disk 20 having such a configuration is stored in the disk storage container, a predetermined number of optical disks 20 are stacked so that the transparent substrate 41 is on the lower side and stored in the tray 2. Since the uppermost optical disk 20 has the protective layer 44, the light reflection layer 43, and the like on the upper side, even if the lid member 3 is formed of a transparent resin material, the characteristics of the recording layer 42 are not deteriorated by the light beam.
[0057]
However, since the lowermost optical disc 20 has the transparent substrate 41 on the lower side, if the lower case 1 and the tray 2 are formed of a transparent resin material, characteristic deterioration due to light rays of the recording layer 42 made of an organic dye occurs. .
[0058]
In order to avoid this problem, a light shielding sheet 40 is interposed between the lower case 1 and the tray 2 as shown in FIG. The light-shielding sheet 40 is composed of, for example, paper, a plastic sheet with low light transmittance, such as a sheet in which an ultraviolet absorber made of a salicylic acid derivative, a benzophenone organic compound, a benzotriazole organic compound, or the like is applied, mixed, or dispersed. . Note that the surface of the light shielding sheet 40 on the lower case 1 side can be printed or described.
[0059]
In the above embodiment, the lock piece 24 is provided on the rear wall 15 of the tray 2. However, the lock piece can be integrally extended from other portions of the tray such as the front wall and the side wall.
[0060]
In the embodiment described above, the locking portion is provided on the top surface of the cylindrical portion 19, but the locking portion can also be formed on the upper side surface of the cylindrical portion.
[0061]
In the above embodiment, the cylindrical tubular portion 19 is provided, but a polygonal tubular portion having a triangular shape or more can also be provided.
[0062]
In the above embodiment, the lid member 3 is pivotally supported on the tray 2, but the lid member 3 is pivotally supported on the lower case 1 and the tray 2 can be disposed therebetween.
[0063]
In the above embodiment, the case where the optical disk 20 is stored has been described. However, the present invention can also be applied to a disk storage container that stores a hard disk or other disk-shaped member.
[0064]
【The invention's effect】
As described above, according to the first to third aspects of the present invention, the disk stored even when the lid member is opened can be stored in the disk storage space by detachably locking the lock piece extending from the tray to the cylindrical portion. This prevents the unit from falling off, so that even if the disc is placed vertically and the lid member is opened, the stored disc does not fall out and come out. It can be stored. Moreover, even if the lid member is opened with the lid member down, there is no possibility that the stored disk is dropped and damaged. For this reason, it is possible to provide a disc storage container with good handleability.
[0065]
In addition, as described above, since the concave portion is provided in the thick portion of the side wall of the tray, the first aspect of the present invention can prevent deformation due to sink marks at the time of forming the tray.
[0066]
Further, as described above, since the light-shielding sheet is interposed between the tray and the lower case in the second aspect of the present invention, it is possible to prevent deterioration of characteristics due to light of the stored disk.
[0067]
Further, as described above, the third aspect of the present invention is that the tray with the lock piece extended is molded with a polyamide-based resin or a polyolefin-based resin having excellent bending resistance, and the lid member has excellent moldability and transparency. By molding with an inexpensive polystyrene-based resin, the balance of rigidity of the entire storage container can be improved.
