Description

Die Erfindung bezieht sich auf eine weitere Ausbildung der in der Patentschrift 473 547 beschriebenen Wiedergabekamera mit in dem mit Verschlußdeckel versehenen Hinterkasten befindlichen zwei Einspannvorrichtungen für den Raster und die Einstellscheibe, welch letztere unmittelbar durch den Bildträger ersetzbar ist, so daß eine Kassette entbehrlich wird.The invention relates to a further embodiment of that described in patent specification 473,547 Playback camera with located in the rear box provided with a locking cover two jigs for the grid and the dial, which latter is directly replaceable by the image carrier, so that a cassette is dispensable.

Nach der Erfindung wird der mit dem Verschlußdeckel und der Einspannvorrichtung zum austauschbaren Halten der Einstellscheibe und des Bildträgers versehene Teil des Hinterkastens der Kamera mit dem Hinterkasten lösbar verbunden, so daß die Möglichkeit geboten wird, Wiedergabekameras, die keine Einspannvorrichtung für das Austauschen der Einstellscheibe gegen den Bildträger besitzen, ohneZuhilfenahme der sonst üblichen Kassette zu benutzen.According to the invention, the with the cap and the clamping device for interchangeable holding of the focusing screen and the image carrier provided part of the rear box the camera is detachably connected to the rear box, so that the possibility is offered Playback cameras that do not have a jig for changing the focusing screen against the image carrier without using the usual cassette.

Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.The invention is shown in an exemplary embodiment in the drawing.

Die Einspannleisten h für die Einstellscheibe d und den Bildträger, die mittels der rechts- und linksgängigen Schraubenspindelng gegeneinander verstellt werden können, befinden sich in einem besonderen mit Verschlußdeckel k versehenen Rahmen «', der in ähnlicher Weise wie die sonst übliche Kassette mit dem Hinterkasten α der Kamera lichtdicht verbunden ist. Der Deckel k läßt sich um eine Querachse j> hochklappen und wird durch Gegengewichte» in aufgeklappter Stellung gehalten.The clamping strips h for the setting disk d and the picture carrier, which can be adjusted against each other by means of the right-hand and left-hand screw spindles, are located in a special frame with a cover k , which is similar to the usual cassette with the rear case α the camera is connected in a light-tight manner. The cover k can be folded up about a transverse axis j and is held in the opened position by counterweights.

Der Anhang a! kann auch zum Halten des Rasters mit Halteleisten b versehen werden, deren Verstellung durch die rechts- und linksgängigen Gewindespindeln g' erfolgt.Appendix a! can also be provided with retaining strips b to hold the grid, the adjustment of which is carried out by the right-hand and left-hand threaded spindles g ' .

Wird der Anhang a' zur Vervollständigung einer Wiedergabekamera benutzt, die für die Bildzerlegung mit einer Rastereinrichtung und mit der Einstellscheibe versehen ist, so erhält er nur die Einspannvorrichtung g, h für den Austausch der Einstellscheibe und der lichtempfindlichen Platte.If the appendix a 'is used to complete a playback camera which is provided with a raster device and the focusing screen for image decomposition, it only contains the clamping device g, h for exchanging the focusing screen and the photosensitive plate.

Vor dem Befestigen des Anhanges a! ist der Mattscheibenrahmen m mit der Mattscheibe d' aus dem Hinterkasten α zu entfernen, weil alsdann an deren Stelle die Mattscheibe oder Einstellscheibe d des Anhanges a' tritt.Before attaching the attachment a! the ground glass frame m with the ground glass plate d 'is to be removed from the rear box α , because then the ground glass or focusing screen d of the appendix a' takes its place.
