Description
Die Erfindung bezieht sich auf ein D.urchlaufkopiergerät, bei dem das von einer _ Kopierlichtquelle mit gleichbleibender Intensität ausgestrahlte Lichtbüschel in seiner sich in der Laufrichtung des Kopiergutes erstreckenden Breite veränderbar ist, insbesondere zum Belichten von Schichtträgern für das Diffusionsverfahren. Es ist bekannt, das Lichtbüschel durch verstellbare Blenden zu verändern. Andererseits ist es bekannt, durch vorgeschaltete Filter die Lichtfarbe des ausgestrahlten Lichtces der Farbempfindlichkeit des Schichtträgers anzupassen. Bekanntlich werden für das Diffusionsverfahren gelbempfindliche Schichtträger verwendet, so daß in der Regel bei solchen Geräten durch eine gelbe Filterfolie beliohtet wird.The invention relates to a continuous copier in which that emitted by a copier light source with constant intensity Light bundle in its width extending in the direction of travel of the material to be copied is changeable, in particular for exposing substrates for the diffusion process. It is known to change the light bundle by means of adjustable diaphragms. on the other hand it is known to change the light color of the light emitted by upstream filters to match the color sensitivity of the support. As is well known, for the Diffusion process used yellow-sensitive support, so that as a rule in such devices is illuminated through a yellow filter film.
Der .Erfindung liegt d.ie Erkenntnis zugrunde, daß man einen, wesentlich. vereinfachten Aufbau erhalten und: den Aufwand einer zusätzlichen Folie vermeiden kann, wenn die Mittel zur Veränderung der Lichtbüschelgröße zugleich. zur Färbung des Lichtes benutzt werden. Das wird erfindungsgemäß dadurch erreicht, daß zwischen Kopierfläche und Kopierlichtquelle eine Blendenöffnung und eine das Kopierlicht auf diese Öffnung lenkende, schwenkbar gelagerte und nach Maßgabe der Farbempfindlichkeit des Schichtträgers gefärbte Reflektorfläche derart angeordnet ist, daß durch deren Schwenkung die Breite des durch die Blendenöffnung hindurchtretenden Lichtbüschels einstellbar ist.The invention is based on the knowledge that one, essentially. Maintain a simplified structure and: Avoid the expense of an additional film can if the means to change the light bundle size at the same time. for coloring of light. This is achieved according to the invention in that between Copy surface and copy light source an aperture and a copy light on this opening directing, pivotably mounted and according to the color sensitivity of the layer support colored reflector surface is arranged such that through their Pivoting the width of the light bundle passing through the aperture is adjustable.
Es hat sich als zweckmäßig erwiesen, als Reflektorschi:cht ein Gelbmetall, z. B. Messing, oder Reinstaluminium anod@ischgeglänzt oder gefärbt zu verwenden, um das übliche -Gelbfilter zu ersetzen.It has proven to be useful to use a yellow metal as the reflector layer, z. B. to use brass, or high-purity aluminum, anodized or colored, to replace the usual yellow filter.
Ein. Ausführungsbeispiel der Erfindung ist in der Abbildung schematisch dargestellt, und im folgenden beschrieben. DüTch ein über Transportrollen 1, a und eine Spannrolle 3 laufendes endloses Band 4 wird ein Schichtträger zusammen mit dem zu reproduzierenden Original in Pfeilrichtung über eine gewölbte lichtdurchlässige Platte 5 geführt und bei diesem Durchgang belichtet. Im Lampengehäuse 6 ist unterhalb der Platte 5 eine Blenden-Öffnung 7 vorgesehen. Das von einer Lichtquelle 8 ausgestrahlte Licht wird in Pfeilrichtung über einen bei g schwenkbar gelagerten Reflektor io durch die Blendenöffnvng 7 hindurch auf die Platte 5 geworfen.A. Embodiment of the invention is shown schematically in the figure and described below. DüTch on over transport rollers 1, a and a tension roller 3 running endless belt 4 becomes a substrate together with the original to be reproduced in the direction of the arrow over a curved translucent Plate 5 out and exposed during this passage. In the lamp housing 6 is below the plate 5 a diaphragm opening 7 is provided. That emitted by a light source 8 Light is transmitted in the direction of the arrow via a reflector which is pivoted at g thrown through the aperture 7 onto the plate 5.
Bei einer 45°-Neigung des Reflektors io erreicht der durch die Blendenöffnung 7 durchtretende Lichtstrom ein. Maximum. Durch Neigungsänderung des. Reflektors io kann der durchtretende Lichtstrom kontinuierlich verkleinert werden, ohne daß die Helligkeit der Lichtquelle 8 verändert wird.If the reflector is inclined at 45 °, it reaches io through the aperture 7 passing luminous flux. Maximum. By changing the inclination of the reflector io the luminous flux passing through can be continuously reduced without the brightness of the light source 8 is changed.
Der Reflektor i9 hat eine gelbe Oberfläche. Er kann z. B. aus Meseing hergestellt sein. Infolgedessen ist das die Platte 5 treffende Licht gelb gefärbt, ohne daß die Einschaltung eines zusätzlichen Filters erforderlich ist.The reflector i9 has a yellow surface. He can z. B. from Meseing be made. As a result, the light hitting the plate 5 is colored yellow, without the need to switch on an additional filter.
