A book case type storage case is frequently used in a magnetic tape cartridge for a VTR or the like, in which an index card is attached in the storage case. However, in the MD storage case, the opening width of the entrance is only about 5-6 mm, and there is no room for inserting the fingertip into the storage case. For the current product, the index card is attached while covering the outer surface of the storage case. , And its outer surface is covered with a packaging film. In such an attached form, after opening the packaging film, the index card and the storage case are easily separated, and the index card is easily lost.

Although it is not impossible to store the index card together with the MD in the storage case, as described above, since the opening width of the entrance is extremely small, the operation of inserting and removing the index card becomes complicated. When removing the MD from the storage case, the index card may be removed by mistake at the same time. When the index card is formed of a single sheet to facilitate taking in and out of the storage case, the index card slides down from the entrance when the MD is removed from the storage case.

An object of the present invention is to provide a book case type storage case having an opening on the front side of the case, but to store the index card in the storage case together with the disk cartridge, and to easily insert and remove the index card.
