Abstract
Abstract A magnetic tape cassette storage case having a casing made up of a pocket for receiving the rear half of a magnetic tape cassette and a broad wall obtained by extending one wall of the pocket. A first cover, swingably connected to the pocket, has a first recess formed in its inner surface. A second cover, swingably connected to the broad wall, has a second recess formed in its inner surface. The first and second recesses receive the cassette's thicker portion in combination when the case is closed by the first and second cover. With the inventive case, the space required for storing the cases is smaller than that required for storing the same number of conventional ones.
