Next, the disk cartridge to be stored will be described with reference to FIG. In the present embodiment, as shown in FIG. 2, a disk cartridge 39 having a substantially rectangular label area 41 formed on the front surface is stored. The dimensions of the disk cartridge 39 in the illustrated direction are such that the horizontal length is about 70 mm and the vertical length is about 67 mm. As shown in the figure, the label area 41 faces the front side of the case body 21, and the label area 41 is located on the left side and the shutter 4 when viewed from the front side.
2 is located on the right side, and with respect to the longitudinal direction of the label area 41, the end on the side where the distance from the edge of the label area 41 is large is on the upper side, and the slidable range 43 of the shutter 42 is on the lower side. Disk cartridge 3 status
9 is the correct storage position. When the disc cartridge 39 is stored in this state, the bottom 23 of the notch 23
The upper limit of the depth of the notch 23 is set so that a does not cover the label area 41.

The storage case 20 according to the present embodiment is configured as described above, and its operation will be described next.

FIGS. 1 to 4 show a state in which the lid 22 is in the open position. In this state, the disk cartridge 39 is inserted into and removed from the case body 21 through the opening 21f of the case body 21. In the present embodiment, for example, up to five mini-disc cartridges 39 can be stored.

The disk cartridge 39 is taken out of the case body 21 when the cover 3 is in the open position.
Is in the open position, the elastic strip 26 projects rearward (outside) of the back plate portion 21b so that the inner surfaces of both flat portions 26b, c sandwiching the curved portion 26a face each other as shown in FIGS. As shown in FIG. 1, a recess 40 is formed at the rear end of the center of the upper end of the disk cartridge 39 a on the innermost side (back plate 21 b side). The size of the recess 40 is determined by the width and depth of the notches 23 and 24 described above, that is, the width of the recess 40 is about 20 mm and the depth is about 1
0 mm and depth is about 10 mm. Since the recess 40 has such dimensions, as shown in FIG. 1, a finger can be inserted into the recess 40, and a finger is placed on the rear surface of the innermost disk cartridge 39a. The five disk cartridges 39 are narrowly pressed and grasped with a finger placed on the front surface of the disk cartridge 39b on the front side (the front plate portion 21a side), and the stored five disk cartridges 39 are easily taken out together. Can be. Also,
In determining the depth and width of the notch 23, in addition to the condition that a finger can be put on the rear surface of the innermost disk cartridge 39a, the label area 41, the shutter 42, and the slidable range of the shutter 42 are set. Since the condition that the notch 23 does not overlap with a certain shutter operation area 43 is set in consideration, temporarily,
The rearmost disk cartridge 39a is turned upside down from the position shown in FIG.
Even when the disc cartridge 39a is stored in the side position, no finger is applied to the label 41 or the shutter 42 of the disc cartridge 39a at the time of removal, and the label 41 is stained or the shutter 42 is deformed by applying force. Can prevent that.

Even when the disc cartridges 39 are taken out one by one by putting fingers on both side faces of the disc cartridge 39, the height of both side plates 21c and 21d is adjusted by the clamping force formed on the side face of the disc cartridge 39. Is lower than the upper edge portion 44a of the concave portion 44, so that the rear side disk cartridge 39a protrudes from the opening edge portion of both side plate portions 21c, d by an amount sufficient to put fingers on both side surfaces thereof, This disk cartridge 39a can be easily taken out. Even if the disc cartridge 39 does not protrude by an amount sufficient to put a finger on, the disc cartridge 39 can be taken out by hooking some kind of jig on the upper edge portion 44a of the concave portion 44. Alternatively, with the finger placed as shown in FIG. 1 and pressing the rear disk cartridge 39a against the front disk cartridge, only the finger put on the rear disk cartridge 39a is slid upward together with the disk cartridge 39a. By doing so, the rear side disk cartridge 39a can be easily
Can be taken out.

Next, the closing operation of the lid 22 will be described.

When the lid 22 is manually rotated in the closing direction (counterclockwise in the figure) about the connecting portion (thin portion) 25 from the open position shown by the solid line in FIG. The piece 26 is bent at both ends with respect to the lid 22 and the back plate portion 21b, and the curved portion 26a is extended, that is, elastic deformation that increases the angle θ formed by the inner surfaces of both flat portions 26b and c is performed. Then, it reaches the position shown by the dashed line in FIG. When reaching the position shown by the dashed line, the lid 22 is automatically closed in the closing direction without receiving any external force due to the restoring force of the elastic strip 26 that attempts to restore the extended curved portion 26a. To the position covering the opening 21f of the case body 21, and is maintained at this position, and the lid 22 assumes the first natural state.

When the lid 22 is further rotated in the closing direction from a state where the lid 22 is maintained at a position covering the opening 21f, as shown in FIG. 7A, the lid-side thin portion 34 is turned into a main-body-side thin portion. Begin to overlap outside of 29. At this time, the portions of the lid-side thin portion 34 and the main body-side thin portion 29 on the connecting portion 25 side are reduced in height, so that the deformation amount of the portions in the molding process and the like can be reduced, and [8A]-in FIG.
[8A] As shown in FIG. 8A which is a cross-sectional view taken along the line, no interference occurs between the thin portions 34 and 29 of each other.
As shown in FIG. 8B, the lid 22 can be closed by smoothly overlapping the lid side thin portion 34 on the outside of the main body side thin portion 29.

As shown in FIG. 7A, with the closing operation, the lid-side engaging projection 35 is configured such that its surface on the front plate portion 22b side is connected to the surface of the main body-side engaging projection 31 on the back plate portion 21b side. As shown in FIG. 7B, the front end portion 35a of the front engagement portion 35a of the lid-side engagement protrusion 35
Is brought into contact with the back plate side end face 31a of the main body side engaging projection 31 to be engaged, the lid 22 is completely closed, and the lid 22 has a force for returning to the first natural state, That is, the clockwise rotating force acts, and the front plate-side end surface 35a of the lid-side engagement protrusion 35 becomes the back plate-side end surface 3 of the main body-side engagement protrusion 31.
1a, the lid 22 is locked to maintain this closed state. Further, the upper end surface 5 of the main body side engagement protrusion 31
1 and the lower end surface 55 of the lid-side engaging protrusion 35 are each formed in a tapered surface shape (see FIG. 1), so that when the engaging protrusions 31 and 35 begin to overlap,
The lid-side engaging protrusion 35 is smoothly guided to the outside of the main-unit-side engaging protrusion 31 while preventing interference between the end surfaces 51 and 55 of the 35.
Even if the end surfaces 51 and 55 are formed not in a tapered shape but in a curved shape, a smooth engaging action can be obtained.

In the above operation, the lid-side engaging projection 35 is always positioned closer to the connecting portion 25 than the front plate-side end surface 31b which is the other end surface of the main body-side engaging projection 31.
It does not catch on the end surface 31b, so that it is not necessary to move over the main body side engaging protrusion 31 and move the lid side engaging protrusion 35 to the connecting portion 25 side from the main body side engaging protrusion 31 as in the conventional case. The operation of pushing the front plate portion 22b of the lid 22 toward the connecting portion 25 is unnecessary, and the lid 22 can be easily locked in the closed position by simply rotating the lid 22. it can. Also, the main body side engaging projection 3
By forming 1 near the boundary (corner) with the front plate portion 21a where deformation due to molding does not easily occur, a reliable engagement action with the lid-side engagement protrusion 35 can be obtained.

When the lid 22 is opened, the lid 22 is manually moved from the closed position shown in FIG.
, And is rotated clockwise about the connecting portion 25 to release the engagement between the main body side engaging projection 31 and the lid body side engaging projection 35, and further rotated to rotate a predetermined angle from the closed position. When the lid 22 reaches the position shown by the dashed line in FIG.
The lid 22 is automatically urged to the open position shown by the solid line without receiving any external force due to the restoring force of the elastic strip 26 for returning the stretched curved portion 26a to its original position. Maintained in position, the lid 22 assumes a second natural state.

Next, the elastic force of the elastic strip 26 will be described. In the first natural state, the lid 22 is maintained at a position covering the opening 21f of the case body 21 by the elastic force of the elastic strip 26. At this time, the elastic force of the elastic strip 26 is set so that the disk cartridge 39 stored in the case main body does not fall even if the storage case 20 is turned upside down with the lid 22 accidentally turned downward. That is, the weight of the five mini-disc cartridges 39 is about 80 g, and even if this load acts on the lid 22 in the first natural state, the elastic strip is formed so that the lid 22 does not rotate in the opening direction. 26 elastic forces are set. For example, it is designed to withstand a load of up to 100 g. If the elastic force is increased more than necessary, it is large to rotate from the open or closed position to the position shown by the dashed line in FIG. 3 against the elastic force of the elastic strip 26 when opening and closing the lid 22. Because it requires power,
The elastic force of the elastic strip 26 can smoothly rotate and can withstand the load of the stored disk cartridges (in the present embodiment, the load of the maximum number of stored five disk cartridges). Set as follows. The elastic force is determined by the width of the elastic strip 26 (that is, the notches 23, 2).
4), thickness, radius of curvature of the curved portion 26a, and the like.

In the case body 21 having a box shape at a deep bottom,
Due to the physical properties of the resin, the front plate 21a and the back plate 21b are likely to be warped during molding. However, in the present embodiment, as shown in FIG. 3, the bottom plate 21e of the case body 21 and the front plate 21a are formed. The groove 36 is formed on the inner surface of the boundary between the bottom plate 21e and the back plate 21b, and the groove 37 is formed on the inner surface of the boundary between the bottom plate 21e and the back plate 21b. And warpage can be prevented.

When the cover 22 is in the closed position,

As shown in FIG. 3, the curved portion 26a of the elastic strip 26 and the rear corner 50 of the lid 22 are substantially aligned with each other, and the outer surface of the elastic strip 26 is in contact with the lid 22 and the back plate. 21
b is in a state of being curved along the outer surface. At this time,
When the radius of curvature of the curved portion 26a is smaller than the radius of curvature of the rear corner 50 of the lid 22, both flat portions 26b and 26c sandwiching the curved portion 26a of the elastic strip 26 are respectively covered by the lid 2
Outer surface of the top plate portion 22a and the back plate portion 21 of the case body 21
b, and the curved portion 26a also protrudes greatly from the lid 22 and the back plate portion 21b. When the film-like sheet is pressed against the storage case 20 and packaged, the film-like sheet is brought into close contact with a step. As a result, the film-like sheet floats on the step and the film is likely to be torn. Therefore, both flat portions 26
b, 26c and the outer surfaces of the top plate portion 22a and the back plate portion 21b are flush with each other, and the radius of curvature of the curved portion 26a and the radius of curvature of the rear side corner portion 50 of the lid 22 are set so that the curved portion 26a does not project. Equal or, as shown, the curved portions 26a such that both flat portions 26b, 26c are slightly concave.
Is made larger than the radius of curvature of the rear corner 50 of the lid 22.

Although the embodiments of the present invention have been described above, the present invention is, of course, not limited thereto, and various modifications can be made based on the technical concept of the present invention.

The number of mini disk cartridges that can be stored is not limited to five, and the present invention can be applied not only to the storage case for mini disk cartridges but also to the storage case for floppy disk cartridges.
