As described above, the storage case is conventionally made of plastic. However, according to the present invention, it suffices to punch a flexible material such as paper and assemble it. Since a flexible material is used as the molding material,
Since existing equipment can be used, it can be manufactured at extremely low cost. Further, although conventional plastics have had pollution problems when discarded, the materials used in the present invention can also be burned, so there is no pollution problem at all. Further, since it is made of paper, it can be recycled and recycled after use. Furthermore, since the stopper is made of a flexible material such as a piece of paper, it has a high strength and can sufficiently withstand the load due to the movement of the recording medium.

In the conventional plastic case, the size of the conventional plastic case is limited, and it is usually impossible to store a booklet larger than 120 × 120 mm. Also, a booklet of a larger size,
For example, it is possible to make 120 × 140 mm and attach it to the outside of a plastic case and store it in one outer box, but this makes it difficult to handle. In the present invention, since there is no protrusion in the portion where the booklet is inserted due to the positional relationship of the stopper, the size of the storage case is fully utilized, and a booklet larger than the conventional booklet, for example, a 120 × 140 mm booklet can be stored without any obstacle. can do. Therefore, booklets such as photo books and booklets can also be stored, and it is possible to meet the recent needs for diversification of booklets. Further, since it is made of paper, the weight of the storage case itself is about half that of the plastic case, which reduces the labor in the store and can deal with the problem of overloading during transportation.
