0, a part of the outer peripheral portion is in the first position.
The first half member 11 and the second half member 12 face outward through cutouts 19 and 24 respectively provided. Therefore, the disc cartridge 1 is pulled out from the storage case 10 while holding the exposed portion. The lock member 15 releases the locked state of the disk cartridge 1 because the apex portion 28a engaged with the clamping recess 8 rides on the side surface by the elastic displacement of the elastic displacement portion 28. Thus, the disk cartridge 1 is further pulled out and taken out of the storage case 10.

In the above-described storage case 10, the lock member holding portion 23 is formed on the second half member 12, but this is formed on the first half member 11 side and the first half member 11 is formed in the assembly process. Needless to say, the second half member 12 may be assembled to the half member 11. In the lock member 15, the elastic displacement portion 28 is formed in an arc shape and the apex portion 28a is configured as an engagement portion with the clamping recess 8 of the disk cartridge 1. For example, the apex portion 28a has an arcuate cross section. It goes without saying that the engaging projections may be formed integrally.

[0050]

As described above in detail, according to the disk cartridge storage case of the present invention, the lock member holding portion formed on one half member is constituted by the engagement support portion having a sufficient height. The lock member is configured such that the lock member has a shaft-like fulcrum portion having a sufficient height with respect to the lock member holding portion and is supported by being relatively engaged with the shaft hole of the engagement support portion. This lock member is firmly held to one half member and no vibration occurs during the assembly process of assembling the other half member without taking special measures such as changing the assembly process or using a special jig for holding. Even when a shock or the like is applied, occurrence of a situation such as dropping from the lock member holding portion is reliably prevented. Therefore, the storage case of the disk cartridge reliably holds the disk cartridge stored in the storage space in the storage state.
