Description

Kopiergerät mit zwei das Kopiergut zwischen sich einschließenden Decken Die Erfindung bezieht sich auf ein Kopiergerät nach Patent 693 oo2. Nach dem Hauptpatent hat das Kopiergerät zwei das Kopiergut zwischen sich einschließende Decken, deren eine durchsichtig ist und die nach dem Einbringen des Kopiergutes mittels ,eines Reißverschlusses miteinander verbunden werden.Copier with two covers enclosing the copy goods between them The invention relates to a copier according to patent 693002. According to the main patent the copier has two ceilings enclosing the copy goods between them one is transparent and after the copied material has been introduced by means of, one Zipper can be connected to each other.

Die vorliegende Erfindung bezweckt eine weitere Ausbildung des Gegenstandes nach dem Hauptpatent, um den Reißverschluß auch für Zylinderkopiergeräte benutzen zu können.The present invention aims at a further development of the subject matter according to the main patent to use the zipper also for cylinder copiers to be able to.

Sie besteht darin, daß die durchsichtige Decke in an sich bekannter Weise durch einen Glaszylinder ersetzt ist und daß die Stoßkanten der den Glaszylinder umschließenden Decke durch einen Reißverachluß miteinander verbunden werden.It consists in the fact that the transparent ceiling in itself is known Way is replaced by a glass cylinder and that the abutting edges of the glass cylinder surrounding blanket can be connected to each other with a zipper.

Es können in vorteilhafter Weise zum Festspannen der Decke auf dem Zylinder zwischen deren Stoßkanten und den Reißverschlußketten elastische Mittel, z. B. Federn, angebracht sein, die beim Schließen des Reißverschlusses gespannt werden.It can be used in an advantageous manner to clamp the ceiling on the Cylinder between their abutting edges and the zipper chains elastic means, z. B. springs, be attached, the tensioned when closing the zipper will.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung dargestellt. Um den Glaszylinder 2 ist lose die Decke 3 gelegt, hinter der das zu kopierende Gut angeordnet ist. Die innere Spannung der Decke einerseits und die an seinen Stoßkanten 4 befestigten Zugfedern 5 andererseits halten die Decke offen. Erst wenn die Reifiverschlußketten 6 durch Heraufziehen des Schlosses verschlossen werden, werden nach und nach von unten nach oben die Zugfedern 5 gespannt, die Stoßkanten 4 ;der Decke gegeneinander gebracht und damit die Decke selbst mit dem von ihr gehaltenen Arbeitsgut gegen den Zylinder 2 gedrückt.An embodiment of the subject matter of the invention is shown in the drawing shown. Around the glass cylinder 2, the cover 3 is loosely placed, behind which the to copying good is arranged. The inner tension of the ceiling on the one hand and the tension springs 5 attached to its abutting edges 4, on the other hand, keep the ceiling open. Only when the circlip chains 6 are closed by pulling up the lock are, the tension springs 5 are gradually tensioned from bottom to top, the abutting edges 4; the ceiling brought against one another and with it the ceiling itself with that held by it Work item pressed against cylinder 2.
