  Anschlussvorrichtung für Zusatzapparate, insbesondere Beleuchtungsvorrichtungen, an photo- graphische Aufnahmeapparate mit verschiedenartig dimensionierten Kassettenfalzen passend. 



   Vorliegende Erfindung bezweckt es, Zusatzapparate, insbesondere Beleuchtungsapparate, die die gewöhnliche Kamera in Vergrösserungs-oder Verkleinerungsapparate umwandeln, an Aufnahmeapparate verschiedenen Formates, mit verschiedenartig dimensionierten Kassettenfalzen anzuschliessen, wodurch eine weitgehende Verbilligung und Vereinfachung in der Herstellung dieser Zusatzapparate möglich bzw. die Verwendung ein und desselben Zusatzapparat-modells an Aufnahmeapparaten verschiedenster Ausführung durchführbar wird. 



   In Fig. i stellt   K   den rückwärtigen Teil der Kamera mit den zur Aufnahme der Kassetten (des Mattscheibenrahmens) dienenden Nuten, Falzen n vor.   A   zeigt den Zusatzapparat, Beleuchtungsvorrichtung usw., der an die Kamera angeschlossen werden soll, was durch die beiden verschiebbaren, in die Falze n der Kamera gehörenden Laschen in geschieht, durch die die bei d gelagerten Federn f auseinandergetrieben werden, wodurch also auch bei verschiedener Distanz der Falze n zueinander die Hilfsapparate an die Kamera genau passend angeschlossen werden können. 



   Fig. 2 zeigt die ganze Anordnung perspektivisch, wobei m die verschiebbaren An-   schlusslaschen, f dieselben   stützenden Federn, d deren Lagerung am Gehäuse des Zusatzapparates   A   bezeichnen. Aus dieser Darstellung geht auch die Rolle der Federn. f als lichtabschliessende Organe an den Schmalseiten hervor.

  Connection device for additional devices, in particular lighting devices, suitable for photographic recording devices with differently dimensioned cassette folds.



   The purpose of the present invention is to connect additional devices, in particular lighting devices, which convert the ordinary camera into enlarging or reducing devices, to recording devices of different formats, with differently dimensioned cassette folds, whereby a substantial reduction in the price and simplification of the production of these additional devices is possible or the use of and the same additional device model can be carried out on recording devices of various designs.



   In FIG. I, K represents the rear part of the camera with the grooves, folds n serving to accommodate the cassettes (the focusing screen frame). A shows the additional device, lighting device, etc., which is to be connected to the camera, which happens through the two sliding tabs belonging to the folds n of the camera, through which the springs f mounted at d are driven apart, thus also with different ones Distance between the folds n to each other, the auxiliary equipment can be connected to the camera to fit exactly.



   2 shows the entire arrangement in perspective, where m denotes the displaceable connection lugs, f denotes the same supporting springs, d denotes their mounting on the housing of the additional apparatus A. The role of the feathers also emerges from this representation. f emerge as light-blocking organs on the narrow sides.

Claims

PATENT CLAIM: Connection device for. Additional devices, in particular lighting devices for photographic recording devices, characterized in that the additional device is provided on two opposing sides with sliding end flaps (m) which engage in the fold (s) of the rear wall of the photographic device and through two narrow sides offset by go0 on the other The additional device attached springs can always be kept at the distance corresponding to the distance between the folds of the camera, these springs also serve to shut off the light.
