Description

Vorrichtung zum Entwickeln belichteter Papiere, wie Photokopien, Lichtpausen u. dgl. Die Erfindung bezieht sich auf eine Vorrichtung zum Entwickeln belichteter Papiere, wie Photokopien, Lichtpausen, bei welcher das zu entwickelnde Papierblatt mit der Schichtseite nach außen auf einer drehbaren, in die Entwicklerflüssigkeit eintauchenden Walze mittels einer den einen Rand des Papierblattes einspannenden Leiste während des Entwicklungsvorganges festgehalten wird.Device for developing exposed papers, such as photocopies, blueprints and the like The invention relates to an apparatus for developing exposed Papers, such as photocopies, blueprints in which the sheet of paper to be developed with the layer side outwards on a rotatable, into the developer liquid immersing roller by means of a clamping one edge of the paper sheet Bar is held during the development process.

Bei -den bekannten Vorrichtungen dieser Art bereitet das Abheben des Papiers nach der Entwicklung oft dadurch Schwierigkeiten, daß das sich der Walze anschmiegende Papier schwer zu erfassen ist. Um diesen. Nachteil zu vermeiden, "ist nach der Erfindung die Halteleiste unter einem solchen Winkel zur Achse der Walze auf dieser befestigt, daß das auf der Walze aufliegende Papierblatt mit einer Ecke seines freien Randes seitwärts über die Walze herausragt, so daß es nach Beendigung des Entwickelns bequem erfaßt und dann leicht wieder von der Walze abgezogen werden kann.In the known devices of this type, the lifting of the prepares After the development of the paper, the difficulties often arise from the fact that the roller snug paper is difficult to grasp. To this one. Disadvantage to avoid "is according to the invention, the retaining bar at such an angle to the axis of the roller attached to this that the sheet of paper lying on the roller with a corner its free edge protrudes sideways over the roller, so that it is finished of the development can be easily grasped and then easily pulled off the roller again can.

Auf der Zeichnung ist die Vorrichtung nach der Erfindung in einem Ausführungsbeispiel in der Ansicht bei geöffnetem Deckel dargestellt.In the drawing, the device according to the invention is in one Embodiment shown in the view with the lid open.

Die Vorrichtung besteht aus dem Trog r, welcher durch den Klappdeckel a, der mit dem Fenster 3 versehen ist, verschlossen werden kann. Der unter Federwirkung stehende Stützhebel q. hält den Deckel a selbsttätig in der Offenstellung. Die Walze 5 ist in den Seitenwänden des Troges z gelagert und kann mittels des Knopfes 6 von Hand gedreht werden. Unter einem Winkel zur Achse der Walze 5 ist auf ihrem Umfang die Festbalteleiste 7 angeordnet, welche mit Zähnen versehen ist, unter welche der Rand des Papierblattes 8 leicht geschoben werden kann und an seinen Kanten festgehalten wird. Durch einen Abfluß 9 im Boden des Troges kann dieser entleert werden.The device consists of the trough r, which through the hinged lid a, which is provided with the window 3, can be closed. The one under spring action standing support lever q. holds the lid a automatically in the open position. The roller 5 is mounted in the side walls of the trough z and can by means of the button 6 of Hand rotated. At an angle to the axis of the roller 5 is on its circumference the Festbalteleiste 7 arranged, which is provided with teeth, under which the Edge of the paper sheet 8 can be easily pushed and held at its edges will. This can be emptied through a drain 9 in the bottom of the trough.

Die Benutzungsweise der Vorrichtung ist folgende: In den Trog r wird die Entwicklerflüssigkeit gegossen. Das zu entwickelnde Papierblatt 8 wird mit seinem einen Van.de unter die Zähne der Festhalteleiste 7 geschoben. Da diese Halteleiste 7 unter einem Winkel zur Achse ,der Walze 5 liegt, ragt die eine Ecke 8' des nicht eingespannten Randes des Papierblattes nach Umlegen um die Walze seitwärts über die Walze heraus, so daß die freiliegende Papierecke nach Beendigung des Ent-,vicklungsvorganges bequem mit den Fingern oder einer Pinzette erfaßt und von der Walze abgehoben werden. kann.The method of use of the device is as follows: In the trough r is poured the developer liquid. The paper sheet to be developed 8 is with his a Van.de pushed under the teeth of the retaining bar 7. Because this retaining bar 7 at an angle to the axis of the roller 5, one corner 8 'of the does not protrude clamped edge of the paper sheet after turning it around the roller sideways over the roller out, so that the exposed corner of the paper after completion of the development process can be easily grasped with your fingers or tweezers and lifted off the roller. can.
