2. Description of the Related Art It is known, for example, from Japanese Utility Model Publication No. 3-39433 to form a bookcase type protective case from a transparent or translucent plastic sheet. It is known in Japanese Utility Model Publication Nos. 4-8545 and 4-22448 to form a remaining amount scale on a transparent window plate of a tape cartridge in order to confirm the remaining amount of the tape. Further, in Japanese Utility Model Publication No. 1-387905, a label is attached to the outer surface of a tape cartridge, and a remaining scale is printed on a label adjacent to a transparent window plate.

[0003]

The remaining amount scale formed on the transparent window plate is integrally formed as a groove or a protrusion when the window plate is molded. Therefore, it is necessary to prepare a dedicated window plate for each different thickness of the magnetic tape, which increases the manufacturing cost of the tape cartridge. If one type of window plate is also used by a plurality of types of tape cartridges having different tape thicknesses, the remaining tape amount cannot be accurately known, so there is no point in providing a remaining amount scale. In this respect, when the remaining amount is displayed on the label on which the remaining amount scale is printed, the remaining amount corresponding to the difference in tape thickness can be displayed at a low cost. However, the label may peel off and lacks reliability during long-term use. When the tape cartridge is loaded in the tape deck, the peeled label may adhere to the loading mechanism and cause a failure. In the case of a tape cartridge stored in a bookcase type protective case,
There is also the inconvenience that the remaining tape amount cannot be confirmed without removing it from the protective case.

An object of the present invention is to provide a bookcase type protective case which allows confirmation of the remaining tape amount even when the tape cartridge is stored. An object of the present invention is to provide a protective case which can confirm the remaining amount of the tape corresponding to the difference in the tape thickness and can easily change the remaining amount display with a small cost. An object of the present invention is to provide a remaining amount indicator on an index card or an instruction manual that is housed in a case body together with a tape cartridge, and even when the tape cartridge is pulled out from the case body,
It is to provide a protective case that allows you to easily check the remaining tape amount.
