Description

Die Erfindung betrifft eine Vorrichtung zur gleichzeitigen Herstellung mehrerer photographischer Kopien nach einem Negativ durch Projizieren des Negativs mittels mehrerer Objektive auf das Kopierpapier o. dgl.The invention relates to an apparatus for the simultaneous production of several photographic images Copies from a negative by projecting the negative through several Lenses on the copy paper or the like.

Bei dem gleichzeitigen Herstellen mehrerer Kopien nach einem Negativ werden mehrere Objektive, z. B. drei oder sechs, verwendet, die neben- oder übereinander angeordnet sind. ίο Dabei hat es sich gezeigt, daß die am Rande befindlichen Objektive von der hinter dem Negativ aufgestellten Lichtquelle weniger Licht erhalten als die mittleren Objektive, und daß infolgedessen die Kopien verschieden ausfallen.If several copies are made at the same time from a negative, several Lenses, e.g. B. three or six, used, which are arranged next to or one above the other. ίο It has been shown that the lenses located on the edge of the one behind the The negative light source receives less light than the middle lenses, and that as a result the copies are different.

Nach der Erfindung wird dieser Nachteil dadurch behoben, daß die Lichtquelle während der Beleuchtung des Negativs zwecks besserer Verteilung des Lichtes auf sämtliche Objektive in einer Bahn beweglich angebracht ist, die im wesentlichen gleichmäßigen Abstand von der die Objektive enthaltenden Fläche hat.According to the invention, this disadvantage is eliminated in that the light source during the illumination of the negative for the purpose of better distribution of the light to all Lenses mounted movably in a path that is substantially uniformly spaced of the area containing the objectives.

In der Zeichnung ist schematisch eineIn the drawing is a schematic

Vorrichtung dargestellt, die beispielsweise zur Ausführung des Verfahrens nach der Erfindung dienen kann.Device shown, for example, for carrying out the method according to the invention can serve.

Abb. ι zeigt eine Anordnung mit radialer Stellung der Objektive und gebogenem Kopierpapier. Fig. Ι shows an arrangement with a radial position of the lenses and curved copy paper.

Abb. 2 zeigt dieselbe Anordnung der Objektive mit parallel zum Negativ in einer Ebene angeordnetem Kopierpapier.Fig. 2 shows the same arrangement of the objectives with parallel to the negative in one Copy paper arranged in a plane.

ίο In. dem Kasten α ist an der Lichtaustrittstelle ein Negativ b angeordnet. Objektive c, d und e entwerfen auf dem Kopierpapier o. dgl. f Bilder in der ihrer Zahl entsprechenden Anzahl. Eine Lichtquelle befindet sich bei g in ihrer Normalstellung, aus der sie in die Stellungen g1 und g2 bewegt werden kann.ίο In. the box α a negative b is arranged at the light exit point. Lenses c, d and e on the copy paper design o. The like. F images to the number of its corresponding number. A light source is in its normal position at g , from which it can be moved into positions g 1 and g 2 .

Diese Bewegung kann während der DauerThis movement can last for a long time

ao gehen. Die Ortsveränderung der Lichtquelle mit Bezug auf die Objektive kann natürlich auch dadurch erreicht werden, daß die Lichtquelle stillsteht und die Objektive bzw. die mit ihnen verbundenen Teile des Apparatesgo ao. The change in location of the light source with respect to the lenses can of course can also be achieved in that the light source is stationary and the lenses or the parts of the apparatus connected to them

as einschließlich des Kopierpapiers in bezug auf die Lichtquelle verschoben werden.as including copy paper related to the light source can be moved.

Die Lichtquelle kann auch auf einer anderen Bahn bewegt werden, als es in der Zeichnung dargestellt ist, beispielsweise auf einer gekrümmten Bahn. Es ist nicht notwendig, daß die Objektive auf einem Kreisbogen oder auf einer Kugelfläche angeordnet sind, und daß das Kopierpapier entsprechend gebogen ist. Das Kopierpapier kann vielmehr auch parallel zur Ebene des Negativs angeordnet sein (Abb. 2); auch können die Objektive in einer zu diesen Ebenen parallelen Ebene liegen.The light source can also be moved on a different path than shown in the drawing is shown, for example on a curved path. It's not necessary, that the lenses are arranged on an arc of a circle or on a spherical surface, and that the copy paper is bent accordingly. Rather, the copy paper can also be arranged parallel to the plane of the negative (Fig. 2); the lenses in lie in a plane parallel to these planes.
