Abstract: It is desired to simplify the problem of putting cassettes in order and to extract cassettes, and to avoid throwing away the standard cassette boxes.The cabinet can hold cassette boxes (5) such as the standard type of cassette boxes in regular commercial use. Swinging components (3) swinging on an axis (4) hold the boxes (5). Each component (3), in its rest position is held in place by a disengageable lug. Cabinets (1) can be connected together in a row by grooves (10) and ribs (11) in dove-tail form. A cover (2) can be fixed removably by means of projections (12) which engage in the grooves (13). The cover can serve as a handle. The cover can receive a cabinet superimposed on the first one by removable connection means (14, 15).

Abstract: A protective case for magnetic tape or film cassettes comprising, on the one hand, a parallelepiped-shaped box dimensioned to hold at least two cassettes, the box having two main parallel faces joined by perpendicular faces and being open at least on one of its faces perpendicular to the main faces and, on the other hand, a carrier hinged to the box so that it can swing between a position where this carrier is engaged in the box and closes at least one of its open faces and a position where this carrier is opened out from the box. The carrier has at least one wall parallel to the main faces of the box, said wall having on each side at least one protrusion to fit into the hub of a cassette. The holding protrusions are preferably placed symmetrically apart on both sides of each wall of the carrier.
