Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a floppy disk,
Magneto-optical disk, audio or video cassette, D
The present invention relates to a cartridge such as a CC, in which all resin parts are made of the same resin to facilitate recycling.

[0002]

2. Description of the Related Art Cartridges for DCC, MFD, MD, etc. are provided with a recording medium such as a disk, tape, etc. in a case to protect them from dust. In this type of cartridge, an opening for inserting a head is generally formed in a case, a shutter member for opening and closing the opening is provided, and a marking member for preventing erroneous erasing is provided. In such a cartridge, ABS, PS, PC resin is usually used for the case, and as another example, the case is molded with polypropylene resin (PP) as shown in Japanese Utility Model Publication No. 5-8777. , The shutter member and the marking member for preventing erroneous erasure are made of different resins such as polyoxymethylene resin (PO
It was molded with a resin such as M).

[0003]

However, in the conventional cartridge, the case is ABS, PS or P.
Since the shutter member and the like are made of C and PP resin by POM, it is necessary to separate the respective resins at the time of disposal in order to recycle, and there is a problem that recycling is difficult. The present invention has been made in view of these problems, and an object thereof is to provide a cartridge that can be easily recycled and can be manufactured in an inexpensive form.

[0004]

According to the present invention, in a cartridge having a recording medium inside, all resin parts constituting the cartridge other than the recording medium are made of the same kind of resin. Further, the present invention is a cartridge having a recording medium inside, a cartridge having an insertion opening for a recording / reproducing head or the like, an opening for driving a medium, and a shutter member for opening and closing at least one of the openings. Therefore, all the resin parts constituting the cartridge including the shutter member other than the recording medium are made of the same kind of resin.

[0005]

According to the cartridge of the present invention, all the resin parts except the recording medium are made of the same resin, for example, polypropylene. Therefore, even when the cartridge is reused at the time of disposal, the resin is disassembled and separated. Without having to do
It can be easily recycled and can be manufactured at low cost.

[0006]

Embodiments of the present invention will now be described with reference to the example of the floppy disk of FIG. 1. The case 10 is constructed by joining an upper half 11 and a lower half 12 and has a disk (recording medium) inside. ) 20 are housed. Upper half 1
1 has a concave portion 11b on the outer surface and an opening 11a for inserting a pickup in the concave portion 11b. Similarly, the lower half 12 has an opening 12c for inserting a drive shaft, a concave portion 12b and an opening 12a for inserting a pickup. Has been formed. The upper half 11 and the lower half 12 are formed by injection molding or the like using polypropylene resin as a raw material. A plug 24 for preventing erroneous erasure is provided on the case 10, and the plug 24 is also made of the same polypropylene resin as the upper and lower halves 11 and 12.

The disk 20 is a cartridge case 10.
Liners 22, 23 between the upper and lower halves 11, 12
It is accommodated by interposing. These liners 22 and 23 are also made of polypropylene resin.

In the cartridge case 10, a slide area is formed by the recess 11b of the upper half 11 and the recess 12b of the lower half 12, and a shutter 30 is provided in the slide area so that the openings 11a and 12a can be opened and closed. The shutter 30 has a U shape and has openings 11a,
An opening 30a corresponding to 12a is formed, and this shutter 30 is also formed by using polypropylene resin as a raw material.

In this embodiment, all resin parts such as the upper half 11, the lower half 12, the liners 22 and 23, the erroneous erasure prevention plug 24 and the shutter 30 are made of polypropylene resin, that is, the same resin. It For this reason, even when recycling the discarded material, it is not necessary to disassemble and separate the raw material resins, and the whole can be handled as a whole, and the recycling can be easily performed.

FIG. 2 shows another embodiment applied to the MD. In this embodiment, a disk 50 as a recording medium is rotatably accommodated in a case 50 formed by joining an upper half 51 and a lower half 52.
1, 52, the shutter lock 63, and the erroneous erasure prevention plug 64 are formed by injection molding or the like using the same resin, for example, polypropylene resin as a raw material. In addition, the upper half 5
1, a concave slide area 51b and a head insertion opening 51a are formed on the outer surface, and similarly, a lower half 5 is formed.
2 is a slide area 52b and an opening 52 for inserting a head.
a and the drive hole 52c are formed.

The case 50 has openings 51a and 52a.
The shutter 65 for opening and closing the
It is provided slidably on 1b and 52b. This shutter 6
Reference numeral 5 is made of metal or resin, and when it is made of resin, it is made of the same resin (polypropylene in this embodiment) as the upper and lower halves 51, 52, shutter lock 63 and erroneous erasure prevention plug 64. . In the figure, 61 is a clamping plate, and this clamping plate 61 is fixed to the disk 60 by caulking using ultrasonic waves, an adhesive, or the like.

Also in this embodiment, although the clamping plate 61 is made of metal, the upper and lower halves 5 are
1,52, accidental erasure prevention plug 64, shutter lock 6
3. All the resin parts of the shutter 65 are molded from the same polypropylene resin. Therefore, when disposing of
Separate collection and recycling are also easy.

In each of the above embodiments, the shutter 3
Although all the components including 0 and 65 are made of polypropylene resin, some components such as the shutters 30 and 65 may be made of metal, and the other resin components may be made of the same resin. That is, all the resin parts except the recording medium of the cartridge may be made of the same resin, and if there is a metal part, it is easy to discriminate it, and therefore, sorting for recycling is also easy.

Further, in each of the above-mentioned embodiments, polypropylene resin is exemplified as the resin, but it is also possible to mold all resin parts with other resins. Further, in each of the above-described embodiments, the cartridge having the shutters 30 and 65 is illustrated, but the invention can be applied to the cartridge having no shutters 30 and 65, and further, the MFD and the MFD.
Not only disk cartridges such as D, audio,
It is also possible to apply to video and tape cassettes such as DCC.

[0015]

As described above, according to the present invention,
Since all the resin parts constituting the cartridge other than the recording medium are molded from the same resin, it is possible to easily separate the resin parts at the time of recycling, and it is possible to omit the separation of the resin parts, which facilitates the recycling.
