ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a disk cartridge storage case for storing a disk cartridge having a built-in disk-like information recording medium, and particularly relates to a disk cartridge storage case for storing a mini-disk cartridge which stores therein in a photomagnetic disk having a diameter of 2.5 inches.
Further, the present invention also relates to an index card used for a cartridge storage case which can stOre a cartridge built-in disk-like information recording medium such as a mini-disk (hereinafter referred to as the MD) through a slot in a storage portion thereof, and particularly relates to a structure designed to improve the durability of an index card.
A disk cartridge has a built-in information recording medium, such am a magnetic disk, an optical disk, a disk, etc. Recently, the size of such a disk cartridge has become able to be reduced as the density of information recording has become high. As such a disk cartridge with a reduced size, a mini-disk disk cartridge with a built-in mini-disk having a diameter of 2.5 inches, called “MD”, has been put into practical use.
The MD cartridge generally uses such a storage case
61
as shown in
FIG. 1
, in order to protect the whole of the cartridge from an external impact or in order to prevent dust from entering the cartridge to thereby make the storage and carrying of the cartridge easy and sure.
As shown in
FIG. 1
, the conventional storage case
61
is constituted by a box-shaped body in which a cartridge storage space
63
of a thin parallelepiped shape is formed in order to store an MD cartridge
60
therein. An insertion port
62
for loading the MD cartridge
60
is opened in one side surface of the storage case
61
. In addition, arched spring members
65
and
65
are disposed on opposite side walls
64
and
64
which define the cartridge storage space
63
. Further, at least the upper wall is formed from transparent resin (such as polycarbonate, polystyrene, AS resin, or the like).
The spring members
65
and
65
project into the storage space
63
so as to elastically engage with recess portions
60
a
and
60
a
formed in opposite side walls of the MD cartridge
60
, when the MD cartridge
60
is inserted into the storage space
63
through the insertion port
62
. Thus, the MD cartridge
60
is held so n not to come of from the storage case
61
unexpectedly.
When an index sheet on which recording contents of a disk, etc., is written is put into such a storage case
61
, it is necessary to insert the index sheet into the narrow storage space
63
through the insertion port
62
. However, if the index sheet is designed to be large enough so that the index sheet does not easily come off when it is forced into the storage space
63
, the capability of insertion of the index sheet becomes low so that the handling becomes poor. On the other hand, if the index sheet is designed to be small enough so that the index sheet can be inserted easily into the storage space
63
, the index sheet may come off easily. Conventionally, therefore, the index sheet is provided in the form of an application seal so that the application seal can be stuck onto the external surface of the storage case
61
.
However, when the index sheet is stuck on the external surface of the storage case
61
, there is a problem that the index sheet is apt to be dirty so that items mentioned on the index sheet becomes impossible to be read.
In addition, as shown in
FIG. 2
, as a conventional cartridge storage case for storing detachably a cartridge
390
with a built in disk recording medium, there is a cartridge storage case
381
comprising a case body
382
of flat parallelepiped provided with an inner space
383
which can store the cartridge
380
.
A insertion port
384
is formed at the upper end In
FIG. 2
showing a case body
382
, and a dimension A of the insertion port
384
in the direction from left to right in
FIG. 2
is larger than a dimension B of the cartridge
380
in the direction from left to right in FIG.
2
. The cartridge
380
is stored in an internal space
383
via the insertion port
384
and detached therefrom.
A case storing the MD is taken and explained hereinafter as an example of the conventional cases. In the vicinity of the innermost portion (the lower end in
FIG. 2
) of the inner space
383
of the case body
382
is provided a pair of lock members
385
capable of oelstic deformation. The lock members
385
are respectively and detachably in engagement with recesses
311
provided on an MD cartridge
380
to hold the MD cartridge
380
to the case body
382
.
In the conventional cartridge storage case
381
described above, there is a problem wherein because of too large dimension of a gap C (=dimension A−dimension B), if, for example, one holds a round corner portion of the cartridge
380
by a fingertip
386
and tries to insert the cartridge into the case body
382
, the posture of the cartridge
380
is apt to oblique relative to the insertion port
394
. Thereby, it is a great possibility that the cartridge
380
is held and caught between a point D in the vicinity of the insertion port
384
and the lock member
385
on the right side in FIG.
2
.
In the case of storing the MD, there is a problem wherein if the cartridge
380
is forced into the case body
382
, the cartridge
380
itself or the lock member
385
of the cartridge storage case
391
is damaged, and then it becomes impossible to pull out the cartridge
380
. There is also a problem in the carriage of the cartridge storage case in which the cartridge
380
vibrates and generates unpleasant noise.
Further, as shown in
FIG. 3
, as a cartridge storage came for storing a cartridge, such as the MD, etc, (not illustrated herein), there is currently available a so-called slot-in storage case.
This storage case
450
is so constructed that a case body
452
of a flat parallelepiped is provided with an insertion port
451
and an inner space
453
to detachably store a cartridge through the insertion port.
When it is desired to detachably attach through the insertion port
451
an index card
454
on which the recording content in the MD, etc is recorded or written, inasmuch as such cartridge storage case is basically constructed to permit a cartridge to be inserted/ejected through the insertion port, the index card has an area in the vicinity of the insertion port side edge
455
, particularly, sites shown by a symbol F in
FIG. 3
, which are cut by cutter, etc. during production of the index card proper and which are subject to deterioration due to rubbing with cartridges, In some cases, cracks occur or wavy wrinkles generate in the insertion direction of the cartridge.
As a result, in the storage cases of the so-called slot-in type, improvement in the durability of index cards was called for.
SUMMARY OF THE INVENTION
It is an object of the present invention to solve the foregoing problem, and particularly it is an object of first, second and third aspects the present invention to provide a disk cartridge storage case in which an index sheet can be disposed in the storage case easily, and can be prevented from easily coming off from the storage case.
The above object of the first, second and third aspects of the present invention can be achieved by a disk cartridge storage case in which a box-shaped body having a disk cartridge storage space and a disk cartridge insertion port communicating with the storage space is constituted by a storage case body and a cover openably/closably provided on the storage case body, wherein
a forward end of an index sheet inserted into the storage case body in a state where the cover is opened contacts with a stepped portion formed on a front end of a bottom wall portion of the storage case body so that the index sheet is disposed in a predetermined position, and the index sheet is fixedly held when the storage case body and the cover are closed relative to each other.
That is, according to the above-mentioned configuration, not only an index sheet can be ea
