first embodiment
[0079] With reference to the accompanying drawings, a preferred embodiment according to the present invention will be hereunder explained in detail. FIGS. 5 and 6 show this invention, of which FIG. 5 illustrates it in an open state, and FIG. 6 illustrates it in a closed state.
[0080] In the drawings, the storage case is manufactured by injection molding, etc. and has a storing portion 12 for receiving the magnetic tape cassette 10, a lid portion 16 integrally connected to the storing portion 12 at its longitudinal side by means of a hinge portion 14. A storage space for the information sheets 17 is formed inside the lid portion 16.
[0081] The storing portion 12 is formed in a rectangular shape according to an exterior dimension of the magnetic tape cassette, and comprises a bottom plate 18 which has at its inner face a plurality of fitting protuberances and recesses corresponding to a configuration of the magnetic tape cassette 10, and a frame-like lateral wall 20 which is formed upri...
second embodiment
[0094] As a variation of the second embodiment, all of the pressing ribs 44, 46 and 48 may be formed of the same shape as illustrated in FIG. 8(a). In such a relationship too, the information sheets need not be positioned in alignment with the two pressing ribs which are respectively formed on the same outer wall, and can be smoothly inserted, thus enhancing the workability.
[0095] Now, a third embodiment according to the present invention will be explained referring to FIGS. 9 and 10. FIG. 9 is a developed view of the storage case according to the third embodiment of the present invention, and FIG. 10 is a sectional view taken along a line L-L in FIG. 9. In this third embodiment, a pair of pressing ribs 62 and 66 are formed inside the sideward outer walls 28a and 28c which confront each other.
[0096] Since the entire structure of the third embodiment is almost the same as that of the storage case in the second embodiment, the same members as in the second embodiment are designated by...
fourth embodiment
[0099] In this fourth embodiment, inside corners between the adjacent two outer walls 28a and 28b, and 28b and 28c respectively, pressing ribs 72 having sheet holding ribs 74 integrally formed therewith are provided in such a manner that the pressing ribs 72 bridge between the two outer walls 28a and 28b, and 28b and 28c like eaves. The pressing rib 72 is in a form of a quadrangular pyramid divided in four, of which a face confronting the cassette serves as a cassette pressing part and a face confronting the lid plate 26 serves as a holding part for the information sheets.
[0100] With the structure wherein the pressing ribs 72 are formed inside the corners between the two adjacent outer walls 28a and 28b, and 28b and 28c bridging both the adjacent walls respectively, the pressing ribs 72 function as reinforcing clamp members. Rigidity of the lid portion 16 is increased and deformation of the lid portion 16 will be prevented. For example, deformation such as inclination of both the ou...
