【0017】

Next, a case where the stopper member 20 is attached to the lid side wall portion 17 will be described with reference to FIGS. 4 to 6. First, the configuration of the mounting opening 32 and the like for mounting the stopper member 20 will be described. As shown in FIG. 4, a mounting opening 32 is formed at the rear end portion of the lid side wall portion 17, and step portions 33 are formed at both side portions of the mounting opening 32. Slits 34,34 are formed in the steps 33, 33, and holding holes 35, 35 are formed in the tips of the slits 34, 34.

【0018】

Further, a projecting piece 36 projecting to the outside of the case is formed at the bottom of the mounting opening 32, and a pair of elongated holes 37, 37 are formed on the surface of the projecting piece 36 facing the stopper member 20. The elongated holes 37, 37 are configured with stroke regulating means 39 (see FIG. 9) in which the protrusions 25, 25 of the block 21 are loosely fitted, and the stroke regulating means 39 is the moving stroke amount of the stopper member 20.

Further, the structure may be such that the elongated hole penetrates the outer side of the case, and the position is regulated only when the stopper member 20 is pushed, that is, the pushing amount is regulated.

【0019】

Next, as shown in FIG. 4, the stopper member 20 is inserted into the mounting opening 32 described above. That is, the stopper member 20 is pressed in the direction of the arrow, and the locking claws 29, 29 at the ends of the elastic portions 28, 28 are inserted into the slits 34, 34. Since the tapered portions 34a and 34a are formed on the inlet side of the slits 34 and 34, the locking claws 29 and 29 can be easily inserted.

【0020】

Then, when the locking claws 29, 29 forcibly pass through the slits 34, 34 and fit into the holding holes 35, 35, the locking claws 29, 29 snap-fit to the lid side wall portion 17 as shown in FIG. The stopper member 20 is firmly attached to the lid side wall portion 17 because it is held by the lid. The locking claws 29, 29 face outward to each other as shown in FIG. 5, but the locking claws 29, 29 are locked in the directions as shown in FIGS. 6 (a) to 6 (c). The direction may be any direction as long as it can stably perform the function, and may be inward, upper, or lower depending on the design conditions and the like.

【0021】

Next, a case where the lid body 15 is closed and the index sheet 40 is stored in the MD cartridge storage case 1 will be described with reference to FIGS. 7 to 8. As shown in FIG. 1, the index sheet 40 is arranged in the cartridge storage space 7 of the storage case main body 3. Next, when the lid 15 is rotated around the rotation shafts 8 and 8 and closed to the case housing 3, the lock claws 23 and 23 come into contact with the inner surfaces of the locking projections 9a and 9a as shown in FIG. , The stopper member 20 enters the inside of the case side wall portion 5. In this case, the elastic portions 28, 28 are in an stretched state. Then, when the lock claws 23, 23 get over the locking projections 9a, 9a, the stopper member 20 is fitted into the locking portions 9, 9 as shown in FIG. 8, and the lid 15 is closed to the storage case body 3. Hold in the state.

【0022】

At this time, in the index sheet 40, the bent portion 40a is held by the lid rear wall portion 18 and the case rear wall portion 6, and the side portions 40b and 40b are the lid side wall portions 17 and 17 and the bottom wall portion of the storage case body 3. It will be in a state of being held by 4. As a result, the index sheet 40 is held in the cartridge storage space 7. The amount of overlap between the lock claws 23,23 and the locking portions 9,9 when the lock claws 23,23 are fitted into the locking portions 9,9 is 0.1 to 0.5 mm, more preferably 0.15 to 0.4 mm. And. That is, if the overlap amount is smaller than 0.1 mm, the engagement between the lock claws 23,23 and the locking portion 9,9 becomes insufficient, and if it is larger than 0.5 mm, the locking claws 23,23 and the locking portion 9,9 This is because it becomes difficult to disengage with.

【0023】

Next, a case where the lid body 15 is opened and the index sheet 40 is taken out from the MD cartridge storage case 1 will be described. First, the MD cartridge 2 is taken out from the MD cartridge storage case 1. Next, the release pressing portion 22 of the stopper member 20 is pushed in with a finger to retract the lock claws 23 and 23 from the lower end edges of the locking projections 9a and 9a. In this state, if you put your finger on the recess 11 of the rear wall of the case 6 and rotate the lid 15 around the rotation shafts 8 and 8 to open it from the case storage body 3, the index 40 can be opened from the cartridge storage space 7. Can be taken out. At this time, as shown in FIG. 9, since the tip portion of the projecting piece 36 enters the inside from the outer surface of the release pressing portion 22, the release pressing portion 22 can be easily pushed by the finger. The penetration amount S is 0.1 to 0.5 mm, more preferably 0.15 to 0.4 mm. The amount of penetration S is determined according to the amount of overlap between the lock claws 23, 23 and the locking portions 9, 9 described above.

【0024】

Next, a case where the MD cartridge 2 is stored in the MD cartridge storage case 1 will be described with reference to FIGS. 8, 10 and 11. As shown in FIG. 8, with the lid 15 closed to the storage case body 3, the MD cartridge 2 is inserted into the cartridge storage space 7 from the insertion slot 25. As shown in FIG. 10, the tip corners 2a and 2a (only one side is shown) of the inserted MD cartridge 2 abuts on the MD cartridge holding portion 24, and the MD cartridge holding portion 24 is pushed out of the case (in the direction of the arrow). ..

【0025】

When the MD cartridge 2 is further inserted from this position, the MD cartridge holding portion 24 is inserted into the recesses 2b and 2b (only one side is shown) formed on both sides of the tip portion of the MD cartridge 2 (see FIG. 11). As a result, the MD cartridge 2 is held so as not to come out of the cartridge storage space 7. In this way, the movement of the stopper member 20 to the inside of the case is restricted by the MD cartridge holding portion 24 entering the recesses 2b and 2b of the MD cartridge 2. Therefore, even if the release pressing portion 22 of the stopper member 20 is further pushed in by a finger, the portion 24a of the stopper member abuts on the MD cartridge 2 and cannot be pushed in. Therefore, since the lock claws 23 and 23 cannot be released from the locking portion 9, the lid 15 does not open from the case housing 3.

【0026】

Further, since the ridges 30 and 30 projecting from the outer surfaces of the ends of the elastic portions 28 and 28 are in contact with the case side wall portion 5, the MD cartridge holding portion 24 is outside the case in the MD cartridge 2. Even when it is pushed out in the direction of the arrow, it is possible to prevent the locking claws 29 and 29 from being pulled to the outside of the case due to the restricting effect of the ridges 30 and 30. Therefore, even if the MD cartridge 2 is repeatedly taken in and out, stress is not repeatedly generated in the bent portion 29a of the locking claw 29, so that there is no risk of damage.

【0027】

The disk cartridge storage case according to the present invention is not limited to the storage case for MD cartridges in the above embodiment, and can be applied to storage cases for other disk cartridges such as 3.5-inch floppy disks and optical disks. Of course. Further, the shapes of the lid body and the storage case body, and the shapes of the stopper member 20 and the locking portion 9 are not limited to the shapes of the lid body 15 and the storage case body 3 of the above embodiment, and various forms can be used. Needless to say, it can be taken.

【0028】
