Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a storage case for storing and storing a disk cartridge represented by a magneto-optical disk.
[0002]
[Prior art]
This type of disk cartridge includes a disk for recording information signals, a main body case for housing the disk, and a shutter for opening and closing a signal read / write window opened in the main body case. The main body case is formed in a quadrangular shape in which the vertical dimension and the horizontal dimension are substantially the same, and the insertion direction to the disk drive is difficult to understand. Generally, the insertion direction instruction mark is applied by printing or engraving.
[0003]
[Problems to be solved by the invention]
However, as disk drives, especially portable disk drives (disc players) become smaller, thinner, and lighter, disk cartridges become smaller, but along with this, insertion direction indication marks must be displayed smaller. As a result, the insertion direction indication mark printed and displayed disappears thinly due to rubbing with other objects as it is used, so that there is a problem that the insertion direction into the disk drive is likely to be erroneous.
[0004]
Therefore, in order to solve such a problem, the outer shape of the disk cartridge is formed in a shape having a corner dropping portion on the front end side to be inserted into the disk drive as shown in FIG. It is conceivable to form it in a form that makes it easy to understand.
However, when a disc cartridge having such an outer shape is stored in a rectangular storage case when being carried or stored, the disc cartridge is likely to rattle in the storage case, and the outer surface of the disc cartridge may be damaged due to rattling. is there.
[0005]
An object of the present invention is to solve such problems, and provides a storage case for a disk cartridge that can store the above-described disk cartridge having an external shape in which the insertion direction into the disk drive is easily understood. There is to do.
[0006]
[Means for Solving the Problems]
As shown in FIG. 1, the storage case of the present invention comprises a disk 1 which is an information storage medium and a cartridge case 2 which stores the disk 1, and the cartridge case 2 inserted into the disk drive is inserted in the insertion direction side. The disc cartridge C formed into a shape having a corner dropping portion 8 in which a corner portion where the side wall 5 of the side wall 5 and the side wall 6 (or 7) adjacent to one side of the side wall 5 intersect is dropped. In addition, a restriction rib 17 is provided inside the rectangular case main body 11 in which the disk cartridge C is removably stored, and when the disk cartridge C is stored in the case main body 11, the restriction rib is formed on the corner drop portion 8 of the disk cartridge C. 17 is in contact.
[0007]
When forming the disk cartridge into a shape having the corner drop portion 8, instead of forming the corner drop portion 8 only on one side of the side wall on the side of insertion into the disk drive, the corner drop is formed on both sides of the side wall 5. It is also possible to form the portions 8 and 8 and to provide the inside of the case main body 11 of the storage case with the regulating ribs 17 that respectively contact the corner dropping portions 8 on both sides thereof.
[0008]
[Action]
When the disc cartridge C is stored in the case main body 11, the regulating rib 17 comes into contact with the corner dropping portion 8 of the disc cartridge C, and it is possible to prevent the disc cartridge C from rattling in the case main body 11 by this contact action.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a disk cartridge storage case according to the present invention will be described with reference to the drawings. 1 and 2, a disk cartridge C accommodates a disk 1 such as a magneto-optical disk for recording information signals in a cartridge case 2 so as to be freely rotatable. For example, the disk cartridge C is commonly called a mini disk. .
[0010]
The cartridge case 2 is formed by joining an upper case 2a and a lower case 2b, which are molded with plastic, in a lid-like shape, and the vertical dimension W and the horizontal dimension W 'are formed in a rectangular shape having substantially the same dimension. . A signal read / write window 3 is opened on one side of the left and right cases of the upper and lower cases 2a and 2b. The window 3 can be opened and closed by a shutter 4 that is slidably mounted in the cartridge case 2 in the front-rear direction. The shutter 4 is closed and urged by a spring (not shown) and is locked and held by a lock mechanism at the closed position.
[0011]
The cartridge case 2 has a front side wall 5 which is the insertion direction side of the disc drive, and right and left side walls 6 and 7 adjacent to the front side wall 5 so that the insertion direction to the disc drive can be clearly seen in appearance. Is formed in a front end arc shape having a convex arcuate corner dropping part 8 in which the corner part where the two intersect is dropped.
[0012]
On the other hand, the storage case of the disk cartridge C has a thin quadrangular cylindrical shape and a case body 11 having an entrance 10 on one side surface. The case body 11 has an upper wall 12, a lower wall 13, left and right side walls 14 and 15, and a rear wall 16, and an entrance 10 is opened on the front surface. And inside the case main body 11, the regulation rib 17 extended to the front from the position near the right-and-left both ends of the rear surface wall 16 is provided.
In this storage case, the disk cartridge C is inserted and stored from the front side wall 5 having the corner drop portion 8. When this is completely stored, the tip end portion 17 a of the restriction rib 17 is the corner drop of the disk cartridge C. It is set so as to contact the portion 8.
[0013]
Therefore, the disk cartridge C is formed in a shape having a corner drop portion 8 in order to clearly indicate the insertion direction into the disk drive, and is stored in the case main body 11 of the storage case from the side having the corner drop portion 8. Even when a gap that causes rattling is formed between the inner surface of the case body 11 and the corner drop portion 8, the disc cartridge C is brought into contact with the corner drop portion 8 by contacting the restriction rib 17. There is no longer a rattling sound coming into contact with the inner surface of the.
[0014]
In the above embodiment, the regulating rib 17 is projected forward from the rear wall 16 inside the case main body 11 of the storage case. However, as shown in FIG. 3, the inner rear ends of the left and right side walls 14 and 15 of the case main body 11 It is also possible to project from the side portion in the horizontal direction or diagonally forward.
Further, in the above embodiment, the disk cartridge C is formed in the shape having the corner dropping portions 8 and 8 on both sides of the front side wall 5, but instead of this, the front side wall 5 and one side thereof as shown in FIG. Even if it is formed in a shape in which only the corner part where the left side wall 6 or the right side wall 7 adjacent to the crossing is dropped, the insertion direction into the disk drive becomes easy to understand, and the storage case of the disk cartridge C having such an outer shape In this case, as a matter of course, it is sufficient to provide the regulating rib 17 only on one side inside the case body 11. In addition, instead of forming the corner dropping part 8 in a convex arc shape, it can also be formed in a diagonal line shape as shown in FIG.
[0015]
The case body 11 of the storage case is not limited to the case body 11 formed in a thin quadrangular cylinder shape or a book case shape having the entrance 10 on one side as in the above-described embodiment. The present invention can be similarly applied to a case main body 11 with a lid that is often used as a storage case for an audio cassette as shown in FIGS. The case main body 11 is formed by connecting a lid 11b having a pocket 19 at the back of the inner surface to a rectangular box-shaped body 11a so as to be pivotable around an axis 20 so that the disk cartridge C can be inserted into the pocket 19. Insertion is possible from the side having the corner drop part 8 so that it can be inserted and removed. In this case, the regulation rib 17 is provided in the interior of the pocket 19.
[0016]
【The invention's effect】
According to the present invention, it is advantageous that the disk cartridge C having the corner drop portion 8 can be stored without rattling.
