Description

Reproduktionskamer"i4i :einem Additionsanhang Die Erfindung bezieht sich auf eine Reproduktionskamera mit einem Additionsanhang.Reproduction camera "i4i: an addition appendix The invention relates on a reproduction camera with an addition attachment.

Bei einem solchen Gerät machte sich der Übelstand geltend, daß sich beim Verschieben der Kassette nach rechts oder nach links infolge des Kassettengewichts eine Verwindung des Kameraträgers ergab. Diese wirkt sich in der Höhe der optischen Achse durch den Hebelarm a erheblich aus und ist die Ursache, daß die Einzelaufnahmen nicht parallel, sondern winklig zueinander stehen.With such a device, the disadvantage asserted itself that when moving the cassette to the right or to the left due to the weight of the cassette a twisting of the camera carrier resulted. This affects the amount of the optical Axis by the lever arm a considerably and is the cause that the individual recordings not parallel, but at an angle to each other.

Dieser Übelstand wird durch die Erfindung beseitigt, indem gemäß der Erfindung mit der quer zur optischen Achse verschiebbaren Kassette ein gegenläufiges Laufgewicht derart gekuppelt ist, daß das aus dem Laufgewicht und dem Kassettengewicht resultierende Gewicht stets über der Stativmitte liegt.This drawback is eliminated by the invention by, according to the Invention with the cassette that can be displaced transversely to the optical axis is an opposite one Barrel weight is coupled in such a way that the barrel weight and the cassette weight resulting weight is always above the center of the tripod.

Die Zeichnung stellt ein Ausführungsbeispiel des Erfindungsgegenstandes dar, und zwar zeigen Fig. i eine Seitenansicht der Reproduktiönskamera mit dem Kassettenanhang, Fig. 2 eine Draufsicht zu Fig. i, Fig. 3 die Rückansicht des Additionsanhangs und Fig. q. eine Seitenansicht zu Fig. 3: Oberhalb des Kastens B (Fig. 3 und 4) sind zwei Lager 9, io angebracht, welche zwei Führungsstangen 11, 12 tragen. Auf diesen Stangen läuft das Gewicht 13. Auf den Lagerböcken 9, io sind noch die Rollen 1q., 15 angebracht, über die ein endloses Seil 16 gelegt ist. Der obere Strang des Seiles ist durch die Klemme 17 mit dem Gegengewicht 13, der untere durch das Winkelstück 18 mit dem Kassettenträger 6 fest verbunden, welcher in der am Kasten _8 befestigten Führung 5 gleitet.The drawing represents an embodiment of the subject matter of the invention Figure 1 shows a side view of the reproduction camera with the cassette attachment, FIG. 2 shows a plan view of FIG. I, FIG. 3 shows the rear view of the addition appendix, and FIG Fig. Q. a side view of Fig. 3: Above the box B (Figs. 3 and 4) two bearings 9, io attached, which two guide rods 11, 12 carry. On this Rods run the weight 13. On the bearing blocks 9, io are still the rollers 1q., 15 attached, over which an endless rope 16 is placed. The top strand of the rope is through the clamp 17 with the counterweight 13, the lower through the elbow 18 firmly connected to the cassette carrier 6, which is attached to the box _8 Guide 5 slides.

Wird nun beispielsweise die Kassette 7 nach rechts geschoben (Fig. 3), so bewegt sich das Gewicht 13, gleichzeitig nach links und gleicht somit das durch das Kassettenübergewicht hervorgerufene Kippmoment mit Bezug auf die Längsachse des Stativs 2o aus. Die optische Achse der Apparatur erfährt somit keine Ausschwingung mehr nach rechts oder nach links, und die Einzelexpositionen sind deshalb sämtlich parallel zueinander.If, for example, the cassette 7 is now pushed to the right (Fig. 3), the weight 13 moves at the same time to the left and thus resembles that overturning moment caused by the overweight of the cassette with respect to the longitudinal axis of the tripod 2o. The optical axis of the apparatus does not experience any oscillation more to the right or to the left, and the individual exposures are therefore all parallel to each other.
