[0018] Next, a state of locking and unlocking by the lock structure of the storage case that also has the above-described structural force will be described. As shown in FIGS. 1 and 3, the storage case 6 can be opened and closed when the outer locking member 18 is removed. In this state, the storage card 6 is stored in the storage chambers 8e and 10e of the storage bodies 8 and 10. The recording card 20 is accommodated by storing 20 and closing the first and second storage bodies 8 and 10. When the first and second storage bodies 8 and 10 are closed in this way, the first and second lock portions 14 and 16 are overlapped and united. Here, when the outer fitting lock member 18 is put on the first and second mouth portions 14 and 16, the engagement pieces 14b and 16b are slightly pushed inward (in the direction of the lock body 14a and 16a). While passing, it passes through the opening 18a of the external fitting lock member 18. At this time, the linear protrusion 16d fits into the groove 18e and slides in the groove, thereby positioning the first and second lock parts 14, 16 and the external fitting lock member 18 smoothly. The external fitting lock member 18 can be attached. As shown in FIG. 5, the engagement pieces 14b, 16b that have entered the inside of the external fitting lock member 18 are spread when the tips of the engagement pieces 14b, 16b reach the engagement portion 18c of the external fitting lock member 18, and their step portions 14c, 16c engages with the engaging portion 18c. Thus, when the step portions 14c, 16c and the engaging portion 18c are engaged, the outer fitting lock member 18 is locked to the first and second lock portions 14, 16, and cannot be pulled out from each other. It will not come off. As a result, the first and second lock portions 14, 16 are held together by the external fitting lock member 18, and the first and second storage bodies 8, 10 are locked in the closed state.

As shown in FIG. 5, when the stepped portions 14c, 16c of the engaging pieces 14b, 16b and the engaging portion 18c are in an engaged state, as shown in FIG. When the pair of disengagement pieces 18b are simultaneously pushed inward by the fingertip, the projection 18d abuts against the engagement pieces 14b, 16b of the first and second lock portions 14, 16 and pushes them inwardly. . Engagement pieces 14b and 16b are pushed inward As a result, the engagement between the stepped portions 14c and 16c at the tip and the stepped engaging portion 18c of the external fitting lock member 18 is released, and the engaging pieces 14b and 16b may pass through the opening 18a again. It will be ready. Here, when the outer fitting lock member 18 is pulled away, the first and second lock portions 14 and 16 come out of the opening portion 18a of the outer fitting lock member 18 and become unlocked. Accordingly, the first and second storage bodies 8 and 10 can be freely opened and closed again, and the recording card 20 stored therein can be taken out. The storage case 6 described above is a force that forms the storage chambers 8e and 10e for storing the recording card 20 and the like in the first and second storage bodies 8 and 10, respectively. A deep storage chamber is formed only in one storage body. The other storage body may be formed as a lid.

[0020] As described above, in the lock structure of the storage case 6 of the present invention, the lock is not released unless the external fitting lock member 18 is removed from the first and second lock portions 14, 16. In order to remove the fitting lock member 18, it is necessary to consciously press the pair of disengagement pieces 18b simultaneously, so that the lock is not released by dropping or simply impacting. For this reason, as shown in FIG. 7, it is possible to reliably protect and store the stored item even when it is hung on the mobile phone 21 or the strap 22 of the game machine which is easily affected by external force. Incidentally, by providing the hole 18g at the front end of the external fitting lock member 18, it is possible to attach a string for hanging without affecting the operability of the disengagement piece 18b.

[0021] The first and second lock portions 14, 16 in the above embodiment have the same shape, and both the first and second lock portions 14, 16 are engaged with the engagement portion 18c of the external fitting lock member 18. The force to be combined The storage case 6 can be locked even if it is not necessarily configured in this way. For example, the structure of the first lock portion 14 is not changed, the shape of the second lock portion 16 is made into a different shape and structure that can be combined, and only the first lock portion 14 is engaged with the external fitting lock member 18. The storage case 6 can be locked even if it is configured to engage with the portion 18c. That is, as shown in FIG. 8, the first lock portion 14 includes a plate-shaped lock portion main body 14a projecting from the end force of the first storage body 8, and the left and right sides and the end of the lock portion main body 14a. And a pair of engaging pieces 14b that project and bend in the root direction, and have the same basic structure as the first lock portion 14 shown in FIG. The basic structure of the second lock portion 17 is that it comprises a substantially plate-shaped lock portion main body 17a from which the end force of the second storage body 10 protrudes. In addition, the first and second lock portions 14 and 17 shown in FIG. 8 are arranged in order to improve the positional accuracy and strength when the first and second storage bodies 8 and 10 are combined by closing. It is structured as follows. As shown in FIG. 9, the first lock portion 14 is set to a thickness that matches the vertical dimension of the opening 18a of the external fitting lock member 18, and has a recess 14e in the center of the lock portion main body 14a. Yes. On the other hand, the lock portion main body 17a of the second lock portion 17 is formed to be shorter and narrower than the lock portion main body 14a of the first lock portion 14, and as shown in FIG. The outer shape conforms to the recess 14e of the lock portion 14 of 1. When the first and second lock portions 14, 17 are combined, the lock portion main body 14a is fitted into the recess 14e, and positioning in the vertical and horizontal directions in the drawing is made more reliable.

[0023] When the external fitting lock member 18 is externally fitted to the first and second lock portions 14, 17 combined in this way, the combined state of the first and second lock portions 14, 17 is maintained, The first and second storage bodies 8, 10 are locked and cannot be opened. At this time, like the first lock portion 14 shown in FIG. 1, the engagement piece 14b of the first lock portion 14 shown in FIGS. The step portion 14c at the position engages with the engagement portion 18c. Further, when the engagement release piece 18b of the outer fitting lock member 18 is pushed inward, the engagement piece 14b is pushed inward by the engagement release piece 18b, so that the step portion 14c and the engagement portion 18c The engagement can be released and the external fitting lock member 18 can be removed.

As shown in FIG. 8 and FIG. 9, a protrusion 17f that protrudes in the direction of the first lock part 14 facing is provided at the tip of the lock part main body 17a of the second lock part 17. In the recess 14e of the first mouth portion 14, a hole 14f that fits the protruding portion 17f is provided. By inserting the protruding portion 17f into the hole 14f, the first and second lock portions 14 and 17 can be more reliably positioned relative to each other.

[0025] Further, by providing the second locking portion 17 with a linear protrusion 17d that fits into the groove 18e of the outer fitting lock member 18, the outer fitting lock member 18 can be easily fitted. .
