For example, the projection 49a does not necessarily need to be formed over the entire circumference of the neck portion of the shaft portion 49 of the stopper body 47 but may be formed only in a part of the circumferential direction of the neck portion of the shaft portion 49. .

Further, the entire shaft portion 49 may be formed in a polygonal column shape, and the transverse cross-sectional shape of the through hole 45 may be a shape in which the slide fits freely in the shaft portion 49.

Again, the stopper 23 is connected to the stopper 23 using the gap S (see Fig. 17) positioned between the inner circumference of the stopper stripping hole 16 and the thinner parts 18 to 21. It is also possible to form a projection to enter so that the stopper 23 does not rotate relative to the stopper fixing portion 17 by the projection and the interval S.

Moreover, the stopper 23 may not rotate with respect to the stopper fixing part 17 by the force which the stopper main body 47 and the fixing member 48 clamp the stopper fixing part 17, or the stopper 23 stops, You may make it adhere | attach to the government 17.

Again, the dust penetrating into the cartridge case main body 3 from the space | interval S is made into the magnitude | size which closes the hole 16 which stops the stopper peeling-off of the large diameter part 50 of the stopper body 47 (refer FIG. 24). You may prevent it.

25 and 26 show a fourth embodiment of the present invention.

In the above-described embodiment, the upper projection piece 36 and the lower projection piece 35b of the lid 4 are formed so as not to overlap in the vertical direction, but in the present embodiment, the lower projection piece 35b is formed in the upper projection piece 36. Even if the lid 4 is inclined to the right side in Fig. 26 when the lid 4 is held upward with the disc 4 recording medium D inserted therein, the cover 4 is installed at a portion opposite to the front side. Since the central portion of the lower surface side of one end of the disc-shaped recording medium D is supported by the lower protrusion piece 35b, the disc-shaped recording medium D can be prevented from falling in the right direction.

In addition, the portion on the lower projection piece 35b facing the upper projection piece 36 is semi-circular in the same shape as the upper projection piece 36, whereby the on-disk recording medium D can be stably held.

In this case, if the semicircular cutout is formed at the rear end edge of the lower surface of the cartridge case body 3 so as to face the portion, the cap 4 is pulled out by catching the upper projection piece 36 and the lower projection piece 35b. The lid 4 is easily taken out.

In addition, the upper protrusion piece 36 may be formed in the same shape as this lower protrusion piece 35b on the right and left sides of the upper part of the circumferential wall 35a like the lower protrusion piece 35b shown in FIG. Like the lower protrusion piece 35b shown in the figure, it may be formed in the same shape as the lower protrusion piece 35b only at both ends of the circumferential direction of the upper part of the circumferential wall 35a.

The upper protrusion piece 36 and the lower protrusion piece 45b may be formed over the entire circumferential length of the circumferential wall 35a.

As shown in Fig. 27, when the upper projection piece 36 is formed on the left and right portions except for the circumferential center portion of the upper portion of the circumferential wall 35a, the upper surface of the disc-shaped recording medium fits the upper projection piece at two points. Because of this, the disk-like recording medium can be supported in a stable state.

In addition, if the upper projection piece 36 and the lower projection piece 35b are formed so as to contact only the non-recording area formed along the outer circumferential edges on both sides of the disk-shaped recording medium, the damage of the recording surface of the disk-shaped recording medium is prevented. It is preferable because it can be done.

In particular, since the upper edge of the upper recording piece 36 is in contact with the edge of the upper surface of the disk recording medium, even if it is formed widely, there is little risk of damaging the recording surface of the recording medium on the disk. It is preferable that the width W (see Fig. 10) is equal to or less than the width of the non-recording area formed along the outer circumference of the disc-shaped recording medium because the lower surface of the green medium is brought into contact with it.

In addition, in each of the above-described embodiments, the disc D is replaced by inserting and supporting one end of the disc D into the lid 4 with the opening 3a side of the cartridge case body 3 facing downward. Although the example has been described, the lid 4 is removed from the cartridge case body 3 with the front end side of the cartridge case body 3 facing downward, and the disk D remaining in the cartridge case body 3 with the fingers. The disk D may be replaced by going in and out.

In addition, in the above-described embodiment, the case where the lid 4 is attached to the cartridge case body 3 and detached is described so that the disc-shaped recording medium is formed to enter and exit the cartridge case body 3, but the lid is simply a cartridge case body ( It may have only the function of closing the opening part of 3), and the disc-shaped recording medium may be made to enter and exit the cartridge case body 3 by human hands.

As described above, the cartridge case according to the present invention has an opening portion for allowing the disk-shaped recording medium to enter and exit in parallel with the recording surface on the rear end surface of the cartridge case body, and the lid for attaching and detaching the disk-shaped recording medium in the outward direction. Since the head access window and the drive shaft insertion window are provided on both sides, the shutter structure is not complicated and can be manufactured at low cost.

In addition, when the engaging means for engaging the lid to the cartridge case body while the lid is mounted on the cartridge case body is provided, the lid can be prevented from being peeled off from the cartridge case body.

In addition, the engaging means is provided on one side of the lid, the engaging arm having a flexible rod connected at one end thereof to the lid, and the engaging arm provided at the other end thereof and protruding outwardly from one edge of the lid. The side wall of the other side of the lid or the side wall of the cartridge case body opposite the lid, when the lid is provided on the side wall of the cartridge case body and the lid is a fitting hole for engaging the engagement portion in the state where the lid is mounted on the cartridge case body. One of the inner surface of the cartridge is formed with a convex portion and fitted on the other side of the lid or on the other side of the inner surface of the side wall of the cartridge case body opposite thereto in a state where the lid is mounted on the cartridge case body. When the fitting recess is fitted to the convex portion, the lid is carted. It can be certainly prevented from being peeled off the support case body.

In addition, when the lid accommodates one end of the disc recording medium on the front end side and one end of the disc recording medium is in a downward state, the cap is fitted to both sides of the disc recording medium by the inclination of the disc recording medium by its own weight. In the case of having a means for supporting the on-disk recording medium in contact with the disc, the lid on the cartridge case body is detached, and the on-disk recording medium is automatically removed from the cartridge case body. .

And a means for supporting the disc-shaped recording medium so as to protrude horizontally over the circumferential wall formed in an arc shape so as to face the outer circumferential surface of one end of the disc-shaped recording medium and along the outer circumferential surface thereof. And an upper projection piece which is formed to face the upper surface of one end of the disk-like recording medium and a lower projection piece that is formed to protrude in the horizontal direction at the lower portion of the circumferential wall and which faces the lower surface of the one end of the disk-shaped recording medium. In the case where the upper surface of the medium abuts the upper projection piece and the lower surface of the disk-like recording medium abuts the lower projection piece so as to support the disk recording medium, the upper projection piece is placed only in the circumferential center portion of the upper portion of the circumferential wall. If it is formed, the slide stroke of the slide core of the mold for forming the upper protrusion piece can be shortened. It can be cheaply and angry geumhyeongbi value.

If the upper projection piece is formed only in the circumferential center portion of the upper portion of the circumferential wall and the lower projection piece is formed in the circumferential center portion of the circumferential wall, the disk-shaped recording medium can be supported because the lower projection portion can support the center of the lower surface of one end of the recording medium on the disk. I can support it in a stable state.

In addition, when the upper projection piece is formed at a portion other than the circumferential center portion in the upper portion of the circumferential wall, the upper surface of the disk-like recording medium abuts on the upper projection piece at two points so that the disk-like recording medium can be supported in a stable state. There is a number.

In addition, when the upper protrusion piece and the lower protrusion piece are formed so as not to overlap each other in the vertical direction, the mold of the lid does not need to be a slide structure, so that the mold cost can be reduced.

In the case where the upper and lower projections are formed so as to contact only the non-recording area of the disk recording medium, damage to the recording surface of the disk recording medium can be prevented. It can be prevented from occurring.

In addition, the disc cartridge according to the present invention shows that the user pulled out the disc recording medium because the user must remove the stopper fixing part and the stopper by cutting the thin part when the user removes the disc recording medium from the cartridge case. ) Can be left.

When the driver fitting groove is formed on the outer surface of the stopper fixing part, the stopper fixing part and the stopper can be easily removed.

If the upper half or the lower half is formed with an opening facing the stopper fixing part on the other side, and the stopper can be fixed to the stopper fixing part through the opening from the outside of the cartridge case body, It is also possible to take a production method in which the disk-shaped recording medium is stored in the cartridge case body, so that it can flexibly respond to the customer's request or the shape of the production line.

In addition, when one end of the stopper is fixed to the stopper fixing part by fitting, since no adhesive is used, the handleability and productivity are improved.

In addition, a through hole is formed in the stopper fixing portion so as to form an opening on the other side of the upper half portion or the lower half portion opposite the stopper fixing portion so that the stopper penetrates the through hole of the stopper fixing portion and one end of the shaft portion. A stopper body having a large diameter portion formed on the outer surface of the stopper fixing portion and abutting the portion around the through hole on the outer surface of the stopper fixing portion, and a fixing member fitted to the shaft portion and fixing the stopper body to the stopper fixing portion. In the case where the stopper fixing part can be fixed to the stopper fixing part via a hole and an opening opening to be removed from the outside, no adhesive is used to fix the stopper to the stopper fixing part, and thus the handleability and productivity are improved.

In addition, since the stopper can be fixed to the stopper fixing part from the outside of the cartridge case main body, a production method of forming the cartridge case main body and storing the disc recording medium in the cartridge case main body can be taken. It is possible to respond flexibly.

When the driver fitting groove is formed in the end surface of the large diameter portion of the stopper, the stopper fixing portion and the stopper can be easily removed.

In addition, when the stopper is formed integrally with the stopper fixing part, the number of parts is reduced, thereby reducing the assembly labor and manufacturing cost.

It provides a cartridge case that can be manufactured at low cost without complicated structure even if the head access window and drive shaft insertion window are installed on both sides, and provides a cartridge case that can easily take out the recording medium on the disc. When the recording medium is removed from the cartridge case, a disc cartridge is provided so that the trace remains.
