Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention rotatably accommodates a disc-shaped information recording medium such as an optical disc, a magneto-optical disc or a magnetic floppy disc capable of recording an information signal such as a tone signal or a video signal. The present invention relates to a disk cartridge housing case for housing a different disk cartridge.

[0002]

2. Description of the Related Art Conventionally, a so-called sleeve case has been proposed as a case for accommodating a disk cartridge in which an information recording medium such as an optical disk is rotatably accommodated.
This sleeve case is formed by bending a sheet material made of a synthetic resin material such as polypropylene or polyethylene terephthalate or cardboard into a case-like shape having an opening at one side, and the disk cartridge is configured inside from the opening. It is inserted into the stored compartment. The sleeve case is formed to a size just needed to store the disc cartridge in the storage portion. As a result, the disc cartridge is configured so that the stored state is maintained by the frictional force between the outer surface of the disc cartridge and the inner surface of the sleeve case.

By the way, in the sleeve case formed by bending the sheet material as described above, the thickness dimension thereof is set to a thickness that allows the bending operation.
It becomes difficult to maintain sufficient rigidity in the sleeve case. Therefore, the sleeve case may be easily deformed when pressure is applied in the thickness direction. As a result, in the sleeve case, the disk cartridge housed in the housing portion may be damaged or deformed by the external pressure.

Further, the sleeve case is easily deformed due to the weight of the disk cartridges when the disk cartridges are stacked and stored while being housed therein. Therefore, the sleeve case
As in the case of receiving the above-mentioned external pressure, the disk cartridge housed in the housing portion may be damaged or deformed.

Further, since the sleeve case holds the disk cartridge housed in the housing part in the housed state by the frictional force with the inner surface of the sleeve case, it can be easily carried out when vibration or shock is applied. It causes a situation such as falling off and damage. Further, in the sleeve case formed by bending the sheet material, it is difficult to make the opening for inserting and removing the disc cartridge into a free shape, which makes the insertion and removal operation of the disc cartridge cumbersome and difficult. However, it has a problem that it is difficult.

In order to solve such a problem, a storage case for a disk cartridge is proposed, which is formed in a box shape by butt-joining a first member on the top plate side and a second member on the bottom plate side. There is. The first member and the second member are provided with sufficient rigidity by being formed by injection molding or the like. On the other hand, these first
The member and the second member are complicated when they are combined by screwing, for example. Also,
When the first member and the second member are structured to be combined by so-called ultrasonic welding, there is a possibility that the surface portion of each member may be damaged due to the propagation of ultrasonic waves, resulting in poor appearance.

Furthermore, in the case of the housing having the combination structure by ultrasonic welding, the fusion rib portion to which the ultrasonic waves are applied is scraped to generate dust, and these particles enter the disk cartridge in which they are housed. Attached to the surface of the optical disc,
There is a problem that recording and reproduction of information signals cannot be performed well. In addition, this storage case has a problem that the ultrasonically welded portion is not sufficiently ensured in an environment of high temperature and high humidity and is peeled off.

On the other hand, in the case of storage in which the first member and the second member are combined by using an adhesive, it takes a certain time for the adhesive to harden, and the adhesive adheres to the bonded portion. There is a problem in that the amount of the adhesive applied must be carefully paid because it may run out of the work, and the work is troublesome. Further, even in the case for storage combined with this adhesive, the durability of the bonded portion is not sufficiently ensured in a high temperature and high humidity environment, and there arises a problem of peeling.

In view of the above circumstances, the first member is constructed by vertically arranging the side wall portions on both side portions and the rear portion of the lower surface portion of the top plate portion, and the second member is the top member. Side wall portions are provided upright on both side portions and a rear portion of the upper surface portion of the bottom plate portion having substantially the same shape as the plate portion, and the first and second members are formed by the above-mentioned first and second members, respectively. There has been proposed a storage case for a disc cartridge in which an opening for inserting a disc cartridge is formed in a storage portion formed inside by combining the side wall portions while sliding the side wall portions.

This storage case adopting this so-called slide assembly structure has a simple structure as a whole and has sufficient rigidity, and the disk cartridge housed in the housing portion is surely protected, and the disk cartridge from the opening portion. Not only can it be easily inserted and removed, but there are various advantages that the work of assembling the first member and the second member is extremely simple.

In the case for storing the disk cartridge, the side wall portion on the side of one of the top plate portion of the first member and the bottom plate portion of the second member has a rear side portion. A mounting portion is integrally formed in the vicinity, and a disc cartridge holding means configured to hold the stored disc cartridge by an engaging member incorporated in the mounting portion. That is, the mounting portion of the disc cartridge holding means is composed of a pair of opposing L-shaped mounting pieces, and an elastic engaging member formed in, for example, a substantially U shape is fitted between the mounting pieces. It becomes. Therefore, by housing the disk cartridge in the disk cartridge housing case, the elastic engaging members come into contact with both side surfaces of the disk cartridge to firmly hold the disk cartridge in the housed state.

[0012]

As described above, the disk cartridge housing case adopting the slide assembly structure having various advantages is a separate member for holding the disk cartridge in the housed state. Since a joining member is required, the number of parts is increased, and there is a problem that the cost is increased as a whole together with the number of assembling steps. Further, when the first member and the second member are combined, the assembling work must be performed while confirming whether or not the elastic engagement member is firmly fitted to the mounting portion. However, there is a problem that the assembly process is troublesome.

Furthermore, since a pair of mounting pieces constituting the mounting portion of the elastic engaging member are integrally projected on the side wall portion on the side of one member, the base end portions of these mounting pieces are The plate thickness of the side wall becomes uneven. Therefore, a concave portion (sink) is likely to occur on the surface of the side wall portion due to molding strain, and stress is concentrated on the base end portion, so that the mounting piece is likely to be deformed or damaged due to a drop impact or the like. There was a point.

Therefore, according to the present invention, the number of parts and the number of assembling steps are reduced to reduce the cost of the product, the stored disk cartridge is securely held, and the shock resistance is improved. It was proposed for the purpose of providing.

[0015]

A case for storing a disk cartridge according to the present invention which achieves this object is constructed by combining a pair of upper and lower halves, and an insertion opening for inserting a disk cartridge into a storage portion formed inside. Are formed on one side surface. At least one of the half halves is integrally formed with an elastic locking projection for holding the disk cartridge in the housing by engaging the clamping recess formed on the back surface of the disk cartridge. .

[0016]

According to the disk cartridge housing case of the present invention constructed as described above, the clamping recess is elastically engaged with the elastic locking projection formed on the inner surface of one of the halves. The disc cartridge inserted into the storage portion through the opening is firmly held in the storage portion.

[0017]

As a result, the disc cartridge 1 has the elastic locking projections 23, 24.
Is firmly held in the storage portion S, and the movement of the disk cartridge storage case 10 from the opening I to the outside is restricted by impact or vibration.

In order to take out the disc cartridge 1 from the disc cartridge housing case 10, the notch portion 2 provided in the front portion of the upper half 11 and the lower half 12 is used.
The rear portion facing the outside is grasped and pulled out from the arcuate notch formed by 2 and 35.

The elastic locking projections 23 and 24 are pressed by both sides of the front portions of the clamping recesses 9A and 9B by the pulling operation of the disk cartridge 1, so that the elastic deformation portions 23B and 24C are elastically deformed. Then, the engaging projections 23C and 24C are released from the clamping recesses 9A and 9B, thereby releasing the locked state of the disc cartridge 1. The engaging projections 23C and 24C ride on the main surface of the disc cartridge 1 when the disc cartridge 1 is further pulled. The elastic locking projections 23 and 24 are accommodated in the engagement projections 23C and 24C by elastically returning the elastic deformation sections 23B and 24B to the initial state when the disk cartridge 1 is taken out from the insertion port I. It returns to the initial state in which it protrudes into the portion S.

As described above, the disk cartridge housing case 10 receives shock and vibration by housing the disk cartridge 1 in the housing S while being firmly held by the elastic locking projections 23 and 24. Even if the disc cartridge 1 is ejected, the phenomenon that the disc cartridge 1 rattles in the storage portion S does not occur. Therefore, in the case 10 for storing the disc cartridge, the elastic locking projections 23, 24 or the cartridge body 5 of the disc cartridge 1 is scraped to generate dust and the like, and the surface of the optical disc 2 rotatably accommodated in the cartridge body 5. The occurrence of inconveniences such as adhesion to the surface is prevented.

In the above embodiment, the case 10 for storing the disk cartridge for storing the disk cartridge 1 for storing the optical disk 2 has been described, but the present invention is also widely applicable to the case for storing the disk cartridge for storing other information recording media. It is applicable. Further, in the above embodiment, the elastic locking projections 23, 24 are provided on the lower half 12 side.
However, in the present invention, as shown in FIGS. 12 and 13, it is needless to say that the elastic locking convex portion may be provided on the upper half 11 side.

As shown in FIG. 13, the top plate portion 13 of the upper half 11 is located inside the side wall portions 14 and 15 in the vicinity of the rear portion thereof and has elastic locking projections 40 (40A, 40B).

A circular escape hole 41 is provided in the top plate portion 13, and this escape hole 41
The lower portion of the elastic deforming portion 42 is closed by an elastically deforming portion 42, and an engaging convex portion 43 bulged inward in the center of the elastic deforming portion 42 is formed in a hemispherical shape. These elastic locking projections 40 are elastic of the disk cartridge storage case 10 of the first embodiment described above when the disk cartridge 1 is stored upside down in the storage portion S of the disk cartridge storage case 10. Similar to the locking projections 23 and 24, the clamping recesses 9A and 9B
Respectively relative to each other. The elastic locking projections may be provided on both the upper half 11 and the lower half 12 respectively. In this case, the disc cartridge 1 can be inserted into the disc cartridge housing case 10 without worrying about the top and bottom.

[0044]

As described in detail above, according to the disk cartridge housing case of the present invention, the elastic locking projection protruding into the housing is housed by relatively engaging the clamping recess. Since the disc cartridge is firmly held, there is no inconvenience that the disc cartridge will fall out due to vibration or impact such as carrying. In addition, the elastic locking projection is formed integrally with the case for storing the disc cartridge,
The number of parts and the assembly process are reduced, and the cost of the product is reduced. Further, the elastic locking convex portion is formed with the engaging convex portion via the thin elastic deforming portion, so that the sink mark is prevented from being generated in the upper half or the lower half and the base end portion of the elastic deforming portion is prevented. Since concentration of stress is eliminated, impact resistance can be improved.
