この発明は上下に２分割された両ケースを合体化してケ
ース本体を構成したディスクカートリッジに関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disk cartridge in which a case body is formed by combining upper and lower two halves of the case.
一般に、この種カートリッジにおいては、磁気ディスク

ケースとを超音波融着手段などで完全結着させたのち、
上記ドロップアウト検出試験に供している。Generally, in this type of cartridge, it is necessary to perform a dropout detection test on the magnetic disk in a substantially completed state. In response to this, in the past, after the upper case and lower case were completely joined together using ultrasonic welding means,
It was subjected to the above dropout detection test.
ところが、上記試験で不合格と判定されたものは、上ケ

の上昇も余儀な（されている。However, since the upper case and lower case of those that are judged to have failed the above test are completely bound together, both cases must be disposed of along with the defective magnetic disk, thus saving resources. Not only is this going against the trend of change, but it is also forcing an increase in manufacturing costs.

る。In the figure, 1 is a case body made of synthetic resin, and this case body 1 is divided into two parts, an upper case 2 and a lower case 3.
Consisting of These upper and lower cases 2 and 3 are joined together by, for example, ultrasonic welding means, with their peripheral walls 4 and 5 abutted against each other. Reference numeral 6.7 denotes a plurality of welded parts for joining provided on each of the peripheral walls 4 and 5 of the upper and lower cases 2.3. For example, the welded part 7 of the lower case 3 is composed of a bottle-shaped projection, and The corresponding fused portion 6 of the upper case 2 is constituted by a recessed portion.

動軸挿通孔である。Near the front of the case body 1, there is a through hole 9 that does not prevent the entry of a drive shaft (not shown) of a recording/reproducing device (not shown).
9 is formed on the upper and lower cases 2 and 3. IO is a sheet-shaped magnetic disk located concentrically with the through hole 9 and housed in the case body 1, and 11.12 is a pair of upper and lower hubs made of synthetic resin, which are joined to each other to generate the magnetic disk. It holds the disk 10 and is rotatably fitted into the through hole 9. 13 is a drive shaft insertion hole formed in the lower hub 12.

いスライダを介して外部操作されるようになっている。14.15 is a magnetic head insertion window located on the front side of the case body 1 (right side in FIG. 1) and formed in the disk setting area, and is located in the radial direction of the disk 10 (direction of arrow a in FIG. 1). The magnetic head H is formed of a long hole that does not hinder the movement of the magnetic head H. 16.17 is upper and lower cases 2 and 3
An annular wall 18.19 formed concentrically with each drive shaft entry hole 9 is a shutter member that opens and closes each magnetic head insertion window 14.15 in the upper and lower cases 2.3. These shutter members 18, 19 are adapted to be externally operated via sliders (not shown).

As shown in B), the first and second
Concave and convex portions 20 and 21 are respectively formed to constitute positioning means.

４も兼務している。Reference numeral 22.23 denotes third positioning recesses and protrusions formed in the upper and lower cases 2.3 on the rear side of the case body l and press-fitted to each other, and together with the first and second positioning means, Temporary coupling means 2 for both cases 2.3 above
4 also serves concurrently.
つぎに、上記構成のディスクカートリッジの製造方法に

外部より移動操作するためのスライダとを連結させる。First, the shutter members 18, 19 are fitted into the annular walls 16, 17 of both the upper and lower cases 2.3 to prevent them from coming off, and the shutter members 18, 19 and this shutter member are moved from the outside. Connect the slider for
一方、磁気ディスク１０を上下１対のハブ１１゜１２間

孔の内縁に嵌合設置する。On the other hand, after the magnetic disk 10 is sandwiched between a pair of upper and lower hubs 11 and 12, this hub block is fitted and installed in the inner edge of the through hole of the lower case 3.
ついで、第１および第２の位置決め用の凹および凸部２
０ （２０）、 ２１ （２１）をそれぞれ圧入嵌合

て上下両ケース２．３を互いに位置決めさせる。Next, the first and second positioning concave and convex portions 2 are formed.
0 (20) and 21 (21) are press-fitted, and the third concave and convex portions 22.23 are press-fitted to position the upper and lower cases 2.3 relative to each other.
さらに、上記各位置決め手段が圧入嵌合構造で仮結合手

るドロップアウト検出試験を行う。Further, since each of the positioning means has a press-fitting structure and also serves as the temporary coupling means 24, the two cases 2.3 are temporarily coupled to each other in a positioned state. That is, in this temporarily coupled state, a dropout detection test is performed on the magnetic disk 10.
上記ドロップアウト検出試験で合格と判定されたものは
・そのままケース合体化工程に送られる。Those that are judged to have passed the dropout detection test above are sent directly to the case merging process.

体化手段は融着手段に限られるものではない。That is, in the merging step, ultrasonic waves are applied to the fused portion 6.7 for combining the upper and lower cases 2.3 while the upper case 2 is pressed against the lower case 3, thereby causing the fusion. The attached parts 6 and 7 are welded to each other and completely bound. Of course, the merging means is not limited to the fusion means.
他方、上記ドロップアウト検出試験で不合格と判定され

たものに対しても、直ちにケースごと廃棄する必要がな
くなり、生産性が上がることになる。On the other hand, if the dropout detection test is judged to have failed, the temporary connection between the upper and lower cases 2 and 3 is released, only the magnetic disk 10 is replaced, and the test is submitted to the above test again. If so, it is sent to the case merging process described above. In other words, the dropout detection test is performed in both cases 2 and 2.
．． By carrying out the process in the temporary bonded state in step 3, there is no need to immediately discard the entire case even if it is determined to be rejected, which increases productivity.

れば完全結合すればよい。The temporary connection of the upper and lower cases 2.3 is not limited to press-fitting the recesses 20 and protrusions 21 formed on the inner walls of the respective cases, but it is also possible to weld only the front parts of the upper and lower cases and make the rear parts open. A dropout detection test may be performed in this state. A dropout detection test is conducted using the disk cartridges temporarily joined in this way, and if it is determined to pass, the rear portions can be welded using ultrasonic waves or the like to completely join. Further, if it is determined that the dropout detection test has failed, the rear part is pushed open and only the magnetic disk 10 is replaced, and the above test is performed again. If the test is passed, complete coupling is performed.
また、ディスクカートリッジ内に収納されるディスクは

ィスクであってもよい。Further, the disk stored in the disk cartridge is not limited to the magnetic disk described in the above embodiment, but may be an optical disk.

上を図ることができる。As mentioned above, there are two upper and lower parts with a head insertion window on the front side.
In a disk cartridge in which a case body is formed by combining divided cases, the case body has positioning means that fit into the inner walls of the case on both sides in the width direction of the head insertion window, and the upper and lower cases are temporarily joined by this positioning means. By using a disc cartridge with a 2-millimeter diameter, it is possible to properly and reliably perform a dropout detection test with the upper and lower cases temporarily connected, eliminating the need to discard defective discs along with the case, saving resources and improving productivity. can be achieved.
