MagnetbandkassetteMagnetic tape cassette

Beschreibungdescription

Die vorliegende Erfindung bezieht sich auf eine Kassette für Magnet "bild- oder Magnettonbänder.The present invention relates to a cartridge for magnetic picture or magnetic audio tapes.

In derartigen Magnetbandkassetten sind ein oberer und ein unterer, Magnetbänder enthaltender Gehäuseteil zusammengefügt und durch Schrauben miteinander verbunden. Infolgedessen können, falls die Schraubenverbindung gelöst wird, beide Gehäuseteile kurz voneinander getrennt und die darin enthaltenen Magnetbänder herausgenommen werden.Im Falle von für den Verleih bestimmten Magnetbildband-Kassetten beispielsweise hat sich daraus das Problem der mißbräuchlichen Handhabung ergeben, bei welcher ein Kunde nach Lösen der Schraubenverbindung bespielte Magnetbänder aus dem Gehäuse herausnimmt und durch unbespielte Bänder ersetzt.In such magnetic tape cassettes there are an upper and a lower housing part containing magnetic tapes put together and connected by screws. As a result, if the screw connection is released, both housing parts are briefly separated from each other and the magnetic tapes contained therein removed In the case of magnetic tape cassettes intended for rental for example, this has given rise to the problem of improper handling at which a customer removes recorded magnetic tapes from the housing after loosening the screw connection and replaced by blank tapes.

Es ist Aufgabe der Erfindung, eine Magnetbandkassette zu schaffen, welche eine derartige mißbräuchliche Handhabung durch Versiegeln von an der Außenseite des Gehäuses befindlichen Teilen der Schrauben verhindert.It is an object of the invention to provide a magnetic tape cassette which can contain such an abusive one Handling prevented by sealing parts of the screws located on the outside of the housing.

nachstehend wird die Erfindung anhand zweier Ausführungsbeispiele unter Beaugimr^-" auf ?,ie Zeichnung näher beschreiben. In the following, the invention is described in more detail using two exemplary embodiments under Beaugimr ^ - "auf ?, ie drawing.

Pig. 1 zeigt in perspektivischer Darstellung eine Magnetbildband-Kassette mit Schrauben 3, die an mehreren Stellen der Oberfläche von einem unteren Gehäuseteil 1 in einen oberen Gehäuseteil 2 eingeschraubt sind. Die Gesamtheit der Schraubenköpfe 3a dieser Schrauben 3 oder wenigstens ein Schraubenkopf ist versiegelt, um ein Lösen von der Außenseite zu verhindern. Zur Verwirklichung des Versiegeins der Schrauben 3 sind Konstruktionen möglich, die beispielsweise das Lösen von der Außenseite verhindern oder bei welchen ein Siegel so angebracht ist, daß ein Versuch zum Lösen desselben sichtbar bleibt (Pig. 2). Es sind auch Konstruktionen möglich, bei welchen die Schraubenköpfe 3a in ein Harz 6 eingebettet sind, welches in eine Vertiefung 5 eingefüllt wird, in der die Schraubenköpfe 3a der Schrauben 3 angeordnet sind.(siehe Pig. 3)·Pig. 1 shows a perspective view of a magnetic tape cassette with screws 3, which are attached to several Places the surface of a lower housing part 1 are screwed into an upper housing part 2. the All of the screw heads 3a of these screws 3 or at least one screw head is sealed to prevent loosening from the outside. To achieve the sealing of the screws 3 constructions are possible, for example, the loosening of the Prevent outside or where a seal is so attached that an attempt to loosen it remains visible (Pig. 2). Constructions are also possible in which the screw heads 3a are made of a resin 6 are embedded, which is filled into a recess 5 in which the screw heads 3a of the Screws 3 are arranged. (See Pig. 3) ·

Da die Magnetbandkassette gemäß der Erfindung derart versiegelt ist, daß die Verbindungsschrauben, wie vorstehend beschrieben, nicht gelöst werden können, wird das Auseinandernehmen der für den Verleih bestimmten Magnetbandkassette unmöglich gemacht. Dadurch wird eine mißbräuchliche Handhabung-, wie der Austausch des Magnetbandes oder dgl. verhindert. Die beschriebenen Ausführungsbeispiele beziehen sich auf Magnetbildband-Kassetten. Jedoch kann, falls notwendig, die gleiche Konstruktion der Schraubenversiegelung auch für Magnettonband-Kassetten benutzt werden.Since the magnetic tape cassette according to the invention is sealed so that the connecting screws as above described cannot be solved, the dismantling is the one intended for rental Magnetic tape cassette made impossible. This prevents improper handling, such as exchanging the Magnetic tape or the like. Prevents. The exemplary embodiments described relate to magnetic image tape cassettes. However, the same screw seal construction can be used for magnetic tape cassettes, if necessary to be used.
