EMI1.1
Den Gegenstand der Erfindung bildet eine Einrichtung zur Entnahme von photographischen Platten aus paramagnetischem Material, die auf einer Seite die lichtempfindliche Schicht tragen, aus einem Magazin, um sie in die Expositionsstellung zu bringen und nach erfolgter Exposition die Platten in einem unter der Kamera angebrachten Entwicklungskasten fallen zu lassen.
Die bisher bekannten Hebevorrichtungen bestehen entweder aus einem Saugnapf oder aus einem permanenten Magneten. Diese Einrichtungen haben den Nachteil, dass die exponierte Platte zwangläufig der Hebevorrichtung entnommen werden muss. Dieser Nachteil wird im Sinne der Erfindung durch die Verwendung eines Elektromagneten behoben, der bei Öffnung des Stromes die Platte selbsttätig loslässt.
Der Erfindungsgegenstand ist in Fig. 1 in Seitenansicht. in Fig. 2 in Vorderansicht dargestellt.
Der Plattenheber ist hinter ein Plattenmagazin 11A auf einer Welle 10 quer zur Öffnung des Objektives in der Kamera 1 drehbar gelagert und besteht aus einem Elektromagneten : 2, der auf dem Heber. 3 aufgeschraubt oder aufgenietet ist. Auf der Welle 10 befinden sich zwei Schleifringe 4. Durch diese wird der Strom einer Batterie 5 mittels zwei Schleiffedern 6 zu dem Magneten geleitet. Statt der Schleifringe 4 und der Schleiffedern 6 kann auch eine Litze verwendet werden.
Durch einen Hebelschalter 7, der aussen auf den Apparat 1 angebracht ist. wird der Stromkreis nach Wunsch geschlossen oder geöffnet. Will man nun eine Aufnahme machen, so wird der Hebel von aussen mittels Schlüssel 8 auf die Platten gedruckt, der Stromkreis wird geschlossen, so dass der Elektromagnet erregt wird und den obersten Bildschiehtträger an sich zieht. Ist dies geschehen. wird der Heber bis zum Anschlag 9 zurückgedreht. Nun kann die Aufnahme erfolgen. Nach beendeter Aufnahme wird der Stromkreis ausgeschaltet und die Platte 11 fällt selbsttätig durch die Gleitschieneu 7 ? in den Eiitwicklungsbehälter (auf der Zeichnung nicht angegeben).

EMI1.1
The subject of the invention is a device for removing photographic plates made of paramagnetic material, which have the photosensitive layer on one side, from a magazine in order to bring them into the exposure position and, after exposure, the plates fall into a development box attached below the camera allow.
The previously known lifting devices consist either of a suction cup or of a permanent magnet. These devices have the disadvantage that the exposed plate has to be removed from the lifting device. This disadvantage is eliminated in the context of the invention by using an electromagnet which automatically releases the plate when the current is opened.
The subject of the invention is shown in FIG. 1 in side view. shown in Fig. 2 in front view.
The plate lifter is rotatably mounted behind a plate magazine 11A on a shaft 10 transversely to the opening of the lens in the camera 1 and consists of an electromagnet: 2, which is on the lifter. 3 is screwed on or riveted on. There are two slip rings 4 on the shaft 10. Through these, the current of a battery 5 is conducted to the magnet by means of two slip springs 6. Instead of the slip rings 4 and the slip springs 6, a stranded wire can also be used.
By a lever switch 7 which is attached to the outside of the apparatus 1. the circuit is closed or opened as desired. If you now want to take a picture, the lever is pressed onto the plates from the outside by means of a key 8, the circuit is closed so that the electromagnet is excited and pulls the uppermost picture carrier towards itself. Did this happen. the jack is turned back to the stop 9. You can now record. After the end of the recording, the circuit is switched off and the plate 11 falls automatically through the slide 7? into the wrapping container (not indicated on the drawing).
