Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case used for carrying a magnetic tape cassette.

[0002]

2. Description of the Related Art A magnetic tape cassette prevents foreign matter such as dust from adhering to the surface of a magnetic tape serving as an information recording medium or damage to the magnetic tape cassette.
It is carried by a storage case for a magnetic tape cassette (hereinafter simply referred to as "storage case"). Further, in recent years, commercial magnetic tape cassettes have tended to increase in size, as opposed to consumer magnetic tape cassettes, in order to improve image quality. For example, in a large cassette (D2L, etc.), since a large amount of magnetic tape is wound,
Some of them weigh more than 4 kg. For this reason, the storage case is important not only for the cassette protection function but also for portability.

A storage case of this type will be described with reference to FIG. The storage case 1 has a case body 3 and a lid portion 5 that is openably and closably connected via a hinge (not shown) provided on the lower surface of the case body 3. The case body 3 and the lid portion 5 cooperate with each other to form a cassette housing portion for housing the tape cassette between them when they are fitted together. A lock member 7 is provided on the upper surface of the case body 3, and the lock member 7 engages with an engagement portion (not shown) provided on the lid portion 5 when the lid portion 5 is closed. The lid 5 can be locked in the closed state.

A grip 9 is provided on the upper surface of the case body 3 so that it can be easily gripped when carrying the case. The case main body 3 and the lid portion 5, including the grip 9, are integrally formed with a hollow inside by blow molding or the like, and the protective function of the magnetic tape cassette is often enhanced. The grip 9 improves the handleability such as storage on a shelf or taking out,
As shown in the figure, it is provided on one end side of the upper surface of the case body. In such a structure in which the grip 9 is deviated to one side in the longitudinal direction of the case, for example, when the storage case 1 is gripped and held (the side opposite to the side where the grip is located is the front side). ), The storage case 1 is slanted down, and the grip 9 is slanted. In this way, the state in which the grip 9 is inclined is a device that allows the storage case 1 to be easily and firmly grasped from an ergonomic point of view (a palm or a structural surface of a finger). Also,
The grip 9 is designed so that the grip width W1 is smaller than the thickness W0 of the storage case 1.

[0005]

However, in the conventional storage case 1, since the thickness of the grip 9 is smaller than the total thickness W of the storage case 1, for example, two storage cases 1 can be simultaneously handled with one hand. When held, as shown in FIG. 8, since the grips 9 are in a state where a relatively wide gap is opened, inconvenience occurs in gripping. That is, when the two grips 9 are not tightly squeezed, the distance between the grips 9 is separated by the thickness of the lid portion 5, which makes it difficult to grip the grips 9, while the grips 9 are forced to approach each other. When gripping strongly, not only a strong grip is required, but the lower parts of the storage cases 1 spread out,
It was difficult to carry. Moreover, although the frequency of carrying two or more storage cases 1 is low, when such a situation arises, it becomes necessary to grip the storage case 1 with a stronger force, or the lower part of the case further expands, which enhances portability. Markedly reduced. Further, in forming the grip 9, it is necessary to complicate the mold, for example, it is necessary to form the grip opening 9a. Particularly, in the case where the inside is hollow and is integrally molded as in blow molding, the grip 9 is manufactured. It was also a factor that increased costs. The present invention has been made in view of the above circumstances, provides a storage case for a magnetic tape cassette that can easily carry a plurality of storage cases, and can be easily manufactured to improve portability and manufacturing cost. The purpose is to reduce

[0006]

The object of the present invention is to:
In a storage case for a magnetic tape cassette, which has a space for storing a magnetic tape cassette and is openable / closable, and which is provided with a grip for holding the case, the grip is selected at least in a position in the thickness direction of the storage case. This is achieved by a storage case characterized by being detachably attached. In a preferred embodiment of the present invention, the grip is formed in a rod shape, and the grip is attached so as to be rotatable about a central axis.

With the configuration of the present invention, for example, when carrying two storage cases at the same time, when the two storage cases are arranged in the thickness direction, the grips of the two storage cases can be selected and attached at positions approaching each other. Because you can
When the grips are in close proximity or in contact with each other, both grips of the two storage cases arranged in the thickness direction of the case are in a well-balanced position with respect to the total weight of the two storage cases and constitute one grip. It works just as it does. In addition, it is possible to avoid a situation in which the distance between the two storage cases is widened at a position away from the grips of both the storage cases, and both storage cases can be easily grasped simultaneously with one hand. Furthermore, if the attached grip is rotatable, the shaking of the storage case is absorbed, and the burden on the wrist during carrying is reduced.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of a storage case for a magnetic tape cassette according to the present invention will be described in detail below with reference to the drawings. 1 is an external perspective view of a storage case according to the present invention, FIG. 2 is an enlarged view of a grip attaching / detaching portion, and FIG. 3 is an explanatory view showing a state in which two storage cases according to the present invention are held side by side. The storage case 11 has a case body 13 and a lid portion 15 that is openably and closably connected via a hinge (not shown) provided on the lower surface of the case body 13. The case main body 13 and the lid portion 15 cooperate with each other to form a cassette housing portion for housing the tape cassette between them when they are fitted together. A lock member 17 is provided on the upper surface of the case body 13, and the lock member 17 engages with an engagement portion (not shown) provided on the lid portion 15 when the lid portion 15 is closed. The lid 15 can be locked in the closed state.

A recess 19 is formed at one end of the upper surface of the case body 13, and the recess 19 is formed in the thickness direction of the storage case 11. Therefore, the lid portion 15 that is openably and closably connected to the case body 13 by a hinge (not shown) avoids the recess 19 by the notch 21 provided on the upper surface side when the case body 13 is fitted to the case body 13 and is attached to the case body 13. It is designed to be closed.

Inner wall surfaces 23a and 23b of the recess 19 which face each other.
As shown in FIG. 2, for example, three fitting holes 25 are formed facing each other, and the fitting holes 25 are arranged in the thickness direction of the case body. A taper groove 27 is formed on the upper surface of the case body above each of the fitting holes 25, and the bottom of the taper groove 27 is connected to the fitting hole 25, so that the groove width becomes smaller toward the fitting hole 25. ing. The taper groove 27 is opened on the upper surface of the case main body, and is also opened on the inner wall surfaces 23 a and 23 b of the recess 19 to reach the fitting hole 25. That is, the fitting holes 25 opened on the inner wall surfaces 23a and 23b are opened on the upper surface of the case body without closing the opening circumference.

The taper groove 27 is formed in a taper shape in which the groove width becomes narrower toward the groove bottom as described above. Therefore, the bottom of the groove is a neck 29 that is narrower than the diameter of the fitting hole 25. Since the case body 13 is made of a resin material or the like, the neck portion 29 can be appropriately elastically displaced in the direction in which the groove width is widened. This insertion hole 2
A grip 31 formed in a rod shape is detachably attached to the member 5. A shaft 33 is projected from both ends of the grip 31. The shaft portion 33 is inserted into the fitting hole 25 by elastically displacing and expanding the neck portion 29 by being pressed toward the fitting hole 25 side from the taper groove 27 opened on the upper surface of the case body. The neck portion 29 prevents the shaft portion 33 inserted into the fitting hole 25 from coming off with a predetermined strength.

Therefore, as shown in FIG. 1, the grip 31 fitted in the fitting holes 25 in which the shaft portions 33 at both ends face each other, is shown in FIG.
It is rotatably attached to the inner wall surfaces 23a and 23b of the recess 19 which face each other. Further, since three sets of fitting holes 25 are provided in the recess 19 so as to face each other in the thickness direction of the case body, the grip 31 can be selectively attached in the thickness direction of the case body.

The storage case 11 thus constructed is
When carrying two storage cases 11 at the same time, the grips 31 are attached in the respective approaching directions, that is, attached to the fitting holes 25 on one end side of one storage case 11, and
When the two storage cases 11 are mounted in the fitting holes 25 on the other end side of the other storage case 11 and are arranged in the thickness direction as shown in FIG. 3, the grips 31 are close to each other (the diameter of the grip is If it is large, the grips may come into contact with each other.).

As described above, according to the storage case 11 described above, since the grip 31 is detachably provided at a position deviated in the thickness direction of the case body, when carrying the two storage cases 11 side by side in the thickness direction, Each grip 31
Can be brought close to each other. As a result, the grips of the two grips 31 become easy, and the open state of the lower portions of the two storage cases 11 due to gripping the separated grips also disappears, and the portability of the plurality of storage cases 11 is greatly improved. Can be made. Further, since the attached grip 31 is rotatably attached, the shaking of the storage case 11 is absorbed, and the burden on the wrist during carrying can be reduced.

Further, according to the storage case 11 described above, since the grip 31 is formed separately from the case body 13,
There is no longer a relatively long and thin part to form the grip part as in the past, and especially when the storage case is integrally molded by blow molding, it is possible to reduce the air pressure and the molding time. Will be easier.

The grip 3 in the storage case 11
The mounting structure of No. 1 is not limited to the above-mentioned mounting structure, and may be another mounting / demounting structure. For example, although not shown, only the fitting holes 25 are formed in the inner wall surfaces 23a and 23b (the structure in which the taper groove 27 is not provided), and at least one of the shaft portions 33 protruding from both ends of the grip 31 is provided inside the grip. By adopting a structure in which a spring or the like is biased in the protruding direction (axial direction), a detachable structure in which the shaft 33 is fitted into the fitting hole 25 by utilizing a change in the protruding amount of the shaft 33 in the grip axis direction can be considered.

Next, another embodiment of the storage case according to the present invention will be described with reference to FIGS. 4 is an external perspective view of a storage case according to another embodiment, FIG. 5 is a view taken in the direction of arrow in FIG. 4, (a) is a view taken in the direction of arrow AA, (b) is a view taken in the direction of arrow BB, and FIG. It is explanatory drawing which shows the state at the time of holding two storage cases of another embodiment in a line. The storage case 41 according to this embodiment has a case body 43 and a lid portion 45 that is openably and closably connected via a hinge (not shown) provided on the lower surface of the case body 43. The central portion of the upper surface of the lid portion 45 is bulging portions 47 and 49. A lock member 51 is provided on the bulging portion 47 of the case body 43, and the lock member 51 engages with a not-shown locking portion provided on the side surface of the bulging portion 49 of the lid portion 45 to close the lid portion 45. It is possible to lock to.

At both ends of the upper surface of the case body 43, there are bulged portions 4
Supporting portions 53 and 55 are provided so as to sandwich 7 therebetween. Grips 57 are attached between the bulging portion 47 and the supporting portions 53 and 55, respectively. As shown in FIG. 5A, the support portion 53 (55) facing the bulging portion 47.
An insertion hole 59 is formed in the inner wall of the, and a fitting hole 61 is formed above the insertion hole 59. Insertion hole 59 and insertion hole 6
